Answer:
The distance from the pitcher's mound to second base and to third base is the same, which is 90 feet. However, the distance from first base to second base is shorter than the distance from first base to third base. This means that the throw to second base is shorter than the throw to third base.
Therefore, the answer is:
The player should throw the ball to 2nd base.
As for how much farther the player must throw the ball for the longer throw, we need more information to calculate that.
use the divergence theorem to evaluate s (5x 7y z2) ds where s is the sphere x2 y2 z2 = 1.
The divergence theorem of the equation S(2x+2y+z2)dS exists 4/3 π.
What is meant by divergence theorem?Let S be the boundary surface of E with the positive (outward) orientation, and let E be a straightforward solid region. Let F be a vector field with continuous partial derivatives on an open region containing E for each of its component functions. Then
\($\iint_S F \cdot d S=\iint_S F \cdot n d S=\iiint_E div Fdv$\),
where n be the outward normal of S.
Let the given equation be
The sphere S is x² + y² + z² = 1
By using concept,
\($$\iint_S F \cdot n d S=\iint_S\left(2 x+2 y+z^2\right) d S$$\)
Therefore,
\($$F \cdot n=2 x+2 y+z^2$$\)
Given that the sphere S is x² + y² + z² = 1
For S, n will be
\($n=\frac{x i+y j+z k}{\sqrt{x^2+y^2+z^2}}$$\)
After substituting the value of x² + y² + z² = 1
n = x i + y j + z k
Therefore,
F(xi + yj + zk) = 2x + 2y + z²
Consider F = Pi + Qj + Rk
\($& (P i+Q j+R k) \cdot(x i+y j+z k)=2 x+2 y+z^2 \\\)
Px + Qy + Rz = 2x + 2y + z²
By comparing the values, P = 2, Q = 2, R = z
So, F becomes
F = 2i + 2j + zk
By using the definition of Divergence,
\(${div} F=\left(\frac{\partial}{\partial x}, \frac{\partial}{\partial y}, \frac{\partial}{\partial z}\right) \cdot(2 i+2 j+z k) \\\)
\($& =\frac{\partial}{\partial x}(2 i+2 j+z k)+\frac{\partial}{\partial y}(2 i+2 j+z k)+\frac{\partial}{\partial z}(2 i+2 j+z k) \\\)
= 0 + 0 + 1
div F = 1
By using Divergence Theorem,
\($ \iint_S F \cdot n d S=\iiint_E {div} F d V \\\)
\($& \iint_S\left(2 x+2 y+z^2\right) d S=\iiint_E 1 d V\)
Since \($\iiint_E 1 d V$\) is the volume of sphere with radius 1
\($& \iint_S\left(2 x+2 y+z^2\right) d S=\text { Volume of } E \\\)
\($& =\frac{4}{3} \pi(1)^3=\frac{4}{3} \pi\)
Thus,
\($\iint_S\left(2 x+2 y+z^2\right) d S=\frac{4}{3} \pi$$\)
Therefore, the divergence theorem of the equation S(2x+2y+z2)dS exists 4/3 π.
The complete question is:
Use the Divergence Theorem to evaluate S(2x+2y+z2)dS where S is the sphere x2+y2+z2=1.

Find the measure of arc EB. Circle A is intersected by line CD at points D and E and line CB at point B, forming angle ECB outside of the circle, the measure of angle ECB is 25 degrees, arc EB is 4x plus 16 degrees, and arc DB 7x plus 6 degrees.
Answer:
\(m\widehat {EB}\) = 96°
Step-by-step explanation:
From the figure attached,
m∠ECB = 25°
\(m\widehat {EB}={(4x+16)}\) degrees
\(m\widehat{DB}=(7x+6)\) degrees
From the theorem of secants intersecting outside the circle,
m∠ECB = \(\frac{1}{2}[m\widehat {DB}-m\widehat{EB}]\)
25° = \(\frac{1}{2}[(7x + 6) - (4x + 16)]\)
25° = \(\frac{1}{2}(3x-10)\)
50 = 3x - 10
3x = 60
x = \(\frac{60}{3}\)
x = 20
\(m\widehat {EB}\) = (4 × 20 + 16)°
= (80 + 16)°
= 96°
Therefore, measure of arc EB is 96°.

A. You have a cylinder with a height of 8 centimeters and a radius of 3 centimeters.
Find the surface area of the cylinder
B.If the radius remains the same but you double the height of the cylinder, will the
surface area also double?
C. If the height remains the same but you double the radius, will the surface area
also double?
And if you get this answer, please add an explanation...
Please
And thank you :-)
Answer:
A. A = 66π cm² ≈ 207.35 cm² B. No, will not. {will be less than double} C. No, will not. {will be more than double}Step-by-step explanation:
A.h = 8 cm, r = 3 cm
A = 2×πr² + 2πr×h = 2πr×(r + h)
A = 2π×3×(3 + 8) = 66π cm² ≈ 207.35 cm²
B.h = 2×8 = 16 cm , r = 3 cm , 2×66π = 132π cm²
A = 2π×3×(3 + 16) = 114π cm² ≠ 132π cm²
C.h = 8 cm , r = 2×3 = 6 cm , 2×66π = 132π cm²
A = 2π×6×(6 + 8) = 168π cm² ≠ 132π cm²
Part(A),
The total surface area of the cylinder is 207.35 cm².
Part(B),
The new surface area is about 2.55 times the original surface area, not double.
Part(C),
The new surface area is about 3.64 times the original surface area, not double.
How to calculate the volume and surface areas of the cylinder?A. To find the surface area of the cylinder, we need to find the area of the two circular bases and the curved lateral surface.
The formula for the area of a circle is A = πr², where r is the radius. So the area of the two circular bases is:
2πr² = 2π(3cm)² = 56.55 cm²
The formula for the lateral surface area of a cylinder is A = 2πrh, where r is the radius and h is the height. So the lateral surface area of the cylinder is:
2πrh = 2π(3cm)(8cm) = 150.8 cm²
Therefore, the total surface area of the cylinder is:
Total Surface Area = 2πr² + 2πrh = 56.55 cm² + 150.8 cm² = 207.35 cm²
B. No, if we double the height of the cylinder while keeping the radius constant, the surface area will not double. The surface area will increase, but not double.
When we double the height, the new height becomes 2 times 8cm = 16cm. Using the formula for the surface area of the cylinder, we get:
New Total Surface Area = 2π(3cm)² + 2π(3cm)(16cm) = 2π(3cm)(28cm) = 528 cm²
The original surface area was 207.35 cm².
The new surface area is 528 cm².
So the new surface area is about 2.55 times the original surface area, not double.
C. No, if we double the radius of the cylinder while keeping the height constant, the surface area will not double. The surface area will increase, but not double.
When we double the radius, the new radius becomes 2 times 3cm = 6cm. Using the formula for the surface area of the cylinder, we get:
New Total Surface Area = 2π(6cm)² + 2π(6cm)(8cm) = 2π(6cm)(20cm) = 753.98 cm²
The original surface area was 207.35 cm².
The new surface area is 753.98 cm².
So the new surface area is about 3.64 times the original surface area, not double.

let f(x) = x 4 2x 2 − x − 3. verify, using algebraic manipulations, that if f(p) = 0 then each of the following four functions have a fixed point at p
g1(x)=(3+x-2x2)1/4
g2(x)=(x+3-x4/2)1/2
g3(x)=x+3/x2+2)1/2
g4(x)=3x4+2x2+3/4x3+4x-1
We cannot verify if each of the four functions g1(x), g2(x), g3(x), and g4(x) have a fixed point at p when f(p) = 0.
To verify that if f(p) = 0, then each of the four functions g1(x), g2(x), g3(x), and g4(x) have a fixed point at p, we need to substitute p into each function and check if the result is equal to p.
g1(x) = (3+x-2x^2)^(1/4)
Let's substitute p into g1(x):
g1(p) = (3+p-2p^2)^(1/4)
To verify if g1(p) = p, we need to show that (3+p-2p^2)^(1/4) = p.
Since this is not an algebraic manipulation that can be solved easily, we cannot confirm if g1(x) has a fixed point at p without further calculations or approximations.
g2(x) = (x+3-x^4/2)^(1/2)
Let's substitute p into g2(x):
g2(p) = (p+3-p^4/2)^(1/2)
To verify if g2(p) = p, we need to show that (p+3-p^4/2)^(1/2) = p.
Since this is not an algebraic manipulation that can be solved easily, we cannot confirm if g2(x) has a fixed point at p without further calculations or approximations.
g3(x) = (x+3/x^2+2)^(1/2)
Let's substitute p into g3(x):
g3(p) = (p+3/p^2+2)^(1/2)
To verify if g3(p) = p, we need to show that (p+3/p^2+2)^(1/2) = p.
Since this is not an algebraic manipulation that can be solved easily, we cannot confirm if g3(x) has a fixed point at p without further calculations or approximations.
g4(x) = (3x^4+2x^2+3)/(4x^3+4x-1)
Let's substitute p into g4(x):
g4(p) = (3p^4+2p^2+3)/(4p^3+4p-1)
To verify if g4(p) = p, we need to show that (3p^4+2p^2+3)/(4p^3+4p-1) = p.
Since this is not an algebraic manipulation that can be solved easily, we cannot confirm if g4(x) has a fixed point at p without further calculations or approximations.
Therefore, based on algebraic manipulations alone, we cannot verify if each of the four functions g1(x), g2(x), g3(x), and g4(x) have a fixed point at p when f(p) = 0. Further calculations or approximations would be required to determine the fixed points of these functions.

What property is “If AB=CD than CD=AB”
The given property “If AB=CD then CD=AB” is known as the symmetric property. Symmetric property is a type of equivalence relation in mathematics that states that if the relation between two elements is in the form of "if A is related to B, then B is related to A," then this type of relation is symmetric.
The symmetric property states that if two objects are related to one another, then this relationship can be reversed. That is, if a=b, then b=a. The symmetric property applies to many different mathematical concepts and structures, including numbers, geometric figures, and functions.For example, if two angles are congruent, then they have the same measure. Using the symmetric property, we can say that if two angles have the same measure, then they are congruent. This property is important in proving theorems and solving problems in geometry, algebra, and other mathematical fields.For such more question on symmetric

A correlation coefficient, r can never be less than -1 or greater than 1. Thus, d. 1.032 is not possible as a correlation coefficient.
The correlation coefficient, r is a measure of the direction and strength of the linear relationship between two variables. The correlation coefficient (r) varies between -1 and 1, with -1 indicating a perfect negative correlation, 0 indicating no correlation, and 1 indicating a perfect positive correlation. A value greater than 1 or less than -1 is not possible. Therefore, the value that could not represent a correlation coefficient is d. 1.032.
Given, the correlation coefficient varies between -1 and 1. The value that could not represent a correlation coefficient is 1.032 since it is greater than 1. A correlation coefficient, r of -1 indicates a perfect negative correlation where one variable decreases as the other increases. A correlation coefficient, r of 1 indicates a perfect positive correlation where both variables move in the same direction.

PLS ANSWER ASAP
Answer:
80 degrees
Step-by-step explanation:
What we see in this drawing is a triangle formed by three lines. In order to solve this problem, we need to know that when two lines intersect, the two angles formed are supplementary (meaning they add up to 180 degrees). For example, the 150-degree angle, and the angle right next to it (the angle on the left side of the triangle) add up to 180 degrees. This means that the left-most angle of the triangle is 180-150, which is 30 degrees
We can figure out the topmost angle of the triangle using the same method. We know that the angle outside the triangle is 130 degrees, so the angle right next to it (in this case, right below it), is 180-130, or 50 degrees.
Next, we use the fact that triangles are 180 degrees on the inside to figure out the third angle (the one on the right, right next to angle 1). We know that the other two angles are 30 and 50 degrees, and if you add that up, you get 80 degrees. The last angle, then, is 180-80, or 100 degrees.
Lastly, we know that the rightmost angle of the triangle and angle 1 add up to 180 degrees. In other words, 100+Angle1=180. Therefore, Angle 1 is 180-100 or 80 degrees.

To find the 98% confidence interval for the number of chocolate chips per cookie in Big Chip cookies, we'll use the t-distribution since the sample size is relatively small (n = 61) and we don't know the population standard deviation.
The formula for the confidence interval is:
\(CI = \bar X \pm t_{critical} \times \dfrac{s } {\sqrt{n}}\)
where:
X is the sample mean,
\(t_{critical\) is the critical value for the t-distribution corresponding to the desired confidence level (98% in this case),
s is the sample standard deviation,
n is the sample size.
First, let's find the critical value for the t-distribution at a 98% confidence level with (n-1) degrees of freedom (df = 61 - 1 = 60). You can use a t-table or a calculator to find this value. For a two-tailed 98% confidence level, the critical value is approximately 2.660.
Given data:
X (sample mean) = 14.3
s (sample standard deviation) = 2.2
n (sample size) = 61
\(t_{critical\) = 2.660 (from the t-distribution table)
Now, calculate the confidence interval:
\(CI = 14.3 \pm 2.660 \times \dfrac{2.2} { \sqrt{61}}\\CI = 14.3 \pm 2.660 \times \dfrac{2.2} { 7.8102}\\CI = 14.3 \pm 0.7471\)
Lower bound = 14.3 - 0.7471 ≈ 13.5529
Upper bound = 14.3 + 0.7471 ≈ 15.0471

1 inches by 2 inches. What are the actual dimensions of her desk?
Answer:
Desk is 2 1/2 ft. by 4 1/2 ft.
Step-by-step explanation:
The scale is 1/2 inch = 1 foot.
To change from drawing size to real size, multiply the drawing size in inches by 2 and change to ft.
Desk is 1 1/4 inches by 2 1/4 inches.
1 1/4 × 2 = 2 1/2
2 1/4 × 2 = 4 1/2
Desk is 2 1/2 ft. by 4 1/2 ft.
maria bought a swimming pool with a circumference of 24 feet. she wants to buy a cover for her pool. what is the approximate size of the cover that maria will need to buy? round your answer to the nearest hundredth.
The approximate size of the cover that Maria will need to buy is 45. 84 square feet
How to determine the valueThe formula for calculating the circumference of a circle is expressed as;
Circumference = πr²
Where 'r' is the radius of the circle
Now, let's substitute the value of the circumference
24 = 2 × 3. 14 × r
r = 24/6. 28
r = 3. 82 feet
Formula for area = πr²
Substitute value of r
Area = 3. 14 × (3. 82)²
Area = 3. 14 × 14. 59
Area = 45. 84 square feet
Hence, the value is 45. 84 square feet

(1 point) Evaluate the integrals that converge, enter 'DNC' if integral Does Not Converge. ʃ1 0 4/³√x dx= ___
The given integral is ∫(1 to 0) (4/³√x)dx = ∫(0 to 1) (4x^(-1/3))dx
To find the integral of this form, we use the power rule of integration of the function x^n.
∫x^n dx = (x^(n+1))/(n+1) + C,
where C is the constant of integration
Now, we have ∫(0 to 1) (4x^(-1/3))dx = 4 ∫(0 to 1) (x^(-1/3))dx
Applying the power rule of integration,
∫(0 to 1) (x^(-1/3))dx = 3[x^(2/3)] (0 to 1)
= 3[1^(2/3) - 0^(2/3)]
= 3 × 1
= 3
Therefore, the integral is equal to 4 × 3 = 12.
Hence, the answer is 12.

Find the abscissa on the curve x2=2y which is nearest
to a
point (4, 1).
The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).
Given the equation x^2 = 2y.
The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:
To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].
Now we need to find the value of x that will minimize this expression.
We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.
Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T
he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).
The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).
