What is the rate of change of the area of a circle with respect to the radius when the radius is 4 in?

Answer:

x = 135,

y = 45

Step-by-step explanation:

45 and y are vertical angles.  That means they are equal

y = 45

45 and x form a straight line which means they sum to 180

45+x = 180

Subtract 45 from each side

45+x-45 =180-45

x = 135

Answer:

1+1=2

Step-by-step explanation:

easy lol

Step-by-step explanation:

the slow intercept form is

y = ax + b

the slope is always the factor a of x (in every line equation).

it is defined as the ratio y/x expressing how many units y changes, when x changes a certain amount of units - e.g. when going from one point on the line to another.

so, for the given 2 points x changes by -5 (from 7 to 2), and y changes by +10 (from 2 to 12).

therefore, the slope is 10/-5 = -2

our line equation looks more like

y = -2x + b

to get b we use the coordinates of one of the points.

e.g. 7, 2

2 = -2×7 + b = -14 + b

b = 16

or full line equation is

y = -2x + 16

Using the standard deviation value of these interarrival times, the coefficient of variation is 0.012.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The standard deviation to mean ratio, or coefficient of variation (CV), illustrates the degree of variability in proportion to the population mean. The dispersion increases with increasing CV.

Formula is given by:

\(CV = \frac {\sigma}{\mu}\)

\(\sigma = 0.02\)

Mean for the time of 0.02 sec is = 79 * 0.02

The time function f(t) = sin t sin 3t can be simplified using the trigonometric identity sin A sin B = 1/2 [cos (A-B) - cos (A+B)].

Starting with f(t) = sin t sin 3t, we can simplify this to f(t) = 1/2 [cos(-3t) - cos(3t)].

Using the double angle formula, we can further simplify the expression: cos (2x) = 2cos^2x - 1. This can be rewritten as: f(t) = 2cos^2(-3t) - 1.

Lastly, we can use the sum formula for cosine to get our final expression: f(t) = 4cos^3(-t) - 3cos(-t).

In conclusion, the time function f(t) = sin t sin 3t can be simplified to f(t) = 4cos^3(-t) - 3cos(-t) using the trigonometric identity sin A sin B = 1/2 [cos (A-B) - cos (A+B)] and the double angle and sum formulas for cosine.

See attached worksheet.

The inequality p(3)⋅x(p(1),w(1)) > w(3) holds, demonstrating that x(p(3),w(3)) cannot be directly revealed preferred to x(p(1),w(1)).

To prove the inequality p(3)⋅x(p(1),w(1)) > w(3), we'll use the transitivity property of the Weak Axiom of Revealed Preference (WARP) and the given conditions.

Since x(p(1),w(1)) is directly or indirectly revealed preferred to x(p(3),w(3)), we know that p(1)⋅x(p(3),w(3)) ≤ w(1). This implies that the cost of x(p(3),w(3)) under the price vector p(1) is affordable within the budget w(1).

Now, let's consider the budget line (p(3),w(3)). We have the budget constraint p(3)⋅x(p(3),w(3)) ≤ w(3). Since the revealed preferred bundle under this budget line is x(p(3),w(3)), the cost of x(p(3),w(3)) under the price vector p(3) is affordable within the budget w(3).

Combining the two inequalities, we get p(3)⋅x(p(3),w(3)) ≤ w(3) and p(1)⋅x(p(3),w(3)) ≤ w(1). Multiplying the second inequality by p(3), we obtain p(3)⋅(p(1)⋅x(p(3),w(3))) ≤ p(3)⋅w(1).

Given that p(n)⋅x(p(n+1),w(n+1)) ≤ w(n) for n=1,2, and using the fact that p(3)⋅x(p(3),w(3)) ≤ w(3), we can rewrite the inequality as p(3)⋅(p(1)⋅x(p(3),w(3))) ≤ w(3).

Since p(3)⋅x(p(3),w(3)) ≤ w(3) and p(3)⋅(p(1)⋅x(p(3),w(3))) ≤ w(3), we can conclude that p(3)⋅x(p(1),w(1)) > w(3).

) and (x

) is m=

x

We now find the slope of the line passing through the points (7,5) and (−9,5) as shown below:

m=

Therefore, the slope of the line is 0.

Now use the slope and either of the two points to find the y-intercept.

y=mx+b

5=(0)(7)+b

b=5

Write the equation in slope intercept form as:

y=mx+b

y=(0)x+5

y=5

Hence, the equation of the line is y=5.

Answer:

a = 3

Step-by-step explanation:

Since the line passes through the origin, we can find its equation using the two given points.

The slope of the line is:

m = (3 - 9) / (40 - a - 2a - 50) = -6 / (10 - 3a)

Using the point (2a+50, 9), we can find the y-intercept (b) of the line:

9 = m(2a+50) + b

b = 9 - m(2a+50)

b = 9 + (6/(3a-10))(2a+50)

So the equation of the line is:

y = (-6 / (3a-10))x + (9 + (6/(3a-10))(2a+50))

Since the line passes through the origin, the y-intercept (b) must be zero. Therefore:

0 = 9 + (6/(3a-10))(2a+50)

6(2a+50) = -9(3a-10)

12a + 300 = -27a + 90

39a = 210

a = 210/39

a = 3

Translated 1 unit right and 2 units up followed by a reflection across x-axis.

Given that, a parallelogram with vertices A(−2, 1), B(−4,−3), C(2,−5), and D(4,−1).

We need to find which sequence of transformations will result in a parallelogram with vertices.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or a geometric figure. The original shape of the object is called the pre-image and the final shape and position of the object is the image under the transformation.

Parallelogram has vertices A(−2, 1), B(−4,−3), C(2,−5), D(4,−1) while parallelogram A'B'C'D' has vertices A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

If a point X(x, y) is translated a units right and b unit up, the new point is X'(x + a, y + b).

If a point X(x, y) is reflected across the x-axis, the new point is X'(x, -y)

If parallelogram ABCD is translated 1 unit right and 2 units up (i.e. x + 1, y + 2), the new points is A'(-1, 3), B'(-3, -1), C'(3, -3), D'(5, -1). If a reflection across x-axis is then done, the new point is A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

Hence, translated 1 unit right and 2 units up followed by a reflection across x-axis.

Answer:

Step-by-step explanation:

given data

mean = 1.9 hours

standard deviation = 0.3 hours

solution

we get here first  random movie between 1.8 and 2.0 hours

so here

P(1.8 < z < 2 )

z = (1.8 - 1.9) ÷ 0.3

z = -0.33

and

z = (2.0 - 1.9) ÷ 0.3

z = 0.33

z = 0.6293

so

P(-0.333 < z < 0.333 )

=  0.26

so random movie is between 1.8 and 2.0 hours long is 0.26

and

A movie is longer than 2.3 hours.

P(x > 2.3)

P( \(\frac{x-\mu }{\sigma}\)  > \(\frac{2.3-\mu }{\sigma}\) )

P (z  > \(\frac{2.3-1.9 }{0.3}\)  )

P (z  > 1.333  )

= 0.091

so chance a movie is longer than 2.3 hours is 0.091

and

length of movie that is shorter than 94% of the movies is

P(x > a ) = 0.94

P(x <  a ) = 0.06

so

P( \(\frac{x-\mu }{\sigma }\) <  \(\frac{a-\mu }{\sigma }\) )

\(\frac{a-1.9 }{0.3 } = -1.55\)

a = 1.43

so length of the movie that is shorter than 94% of the movies about 1.4 hours.

Answer:  First, we need to find the composite function (fg)(x):

(fg)(x) = f(g(x))

= f(-4x-3)

= (-4x-3)^2 + (-4x-3) + 9 (substituting g(x) into f(x))

= 16x^2 + 24x + 18

Therefore, (fg)(x) = 16x^2 + 24x + 18.

Next, we need to find the quotient function (f/g)(x):

(f/g)(x) = f(x) / g(x)

= (x^2 + x + 9) / (-4x - 3) (substituting f(x) and g(x))

To simplify this expression, we can use polynomial long division or synthetic division. Using synthetic division, we get:

  -4 |   1    1    9

      |_____-4__ 12

      |  1  -3   21

Therefore, (f/g)(x) = -4x + 3 - 21 / (-4x - 3)

Simplifying further, we get:

(f/g)(x) = -4x + 3 + (21/4)(1/(x + 3/4))

Therefore, (f/g)(x) = -4x + 3 + (21/4)(1/(x + 3/4)).

As per the estimation method, the best approximation of root of 51 is D. 7.1.

Estimation method:

In math, estimation method gives us an approximate answer and is usually not accurate to more than 1 decimal place. However, it is easy to perform as can be seen under.

Given

Here we need to find the best approximation of the root of 51

In order to solve this one, we have to perform the following steps,

First, we have to find a perfect square that is smaller than 51 and one that is bigger than 51. In this case, 7 and 8 will work as their squares are 49 and 64.

Now, we have to writing in terms of inequality

=> 7<√51<8 = 49<51<64

Then we have to Multiply by 10 and write in terms of square roots

=> √4900<√5100<√6400

Now, we have to move closer to inequality

=> √5041<√5100<√5184 = 71<10√51<72

=>  7.1<√51<7.2

Then by taking average of upper and lower limits, we get

=> (7.1 + 7.2)/2 = 7.15

Therefore, we can estimate the square root of 51 is approximately 7.1.

The probability of the first cube landing showing a 1 and the second cube landing showing a number that is not 1 is b. 0.139.

To find the probability of the first cube landing showing a 1 and the second cube landing showing a number that is not 1, we need to consider the probabilities of each event separately and multiply them together.

The probability of the first cube landing showing a 1 is 1/6 since there is one favorable outcome (getting a 1) out of six possible outcomes (numbers 1 to 6 on the cube).

The probability of the second cube landing showing a number that is not 1 is 5/6 since there are five favorable outcomes (numbers 2 to 6) out of six possible outcomes.

To find the combined probability, we multiply these probabilities: (1/6) * (5/6) = 5/36.

Rounded to the nearest thousandth, the probability is approximately 0.139.

Therefore, the correct answer is b. 0.139.
