Step-by-step explanation:

Remember in a RIGHT triangle ,  cos = adj leg /  hypotenuse

for this one then

cos (37) = 11/x       re-arrange to

x = 11/cos 37

x = 11/ .7986 = 13.8 units

Answer:

  13.77

Step-by-step explanation:

You want the hypotenuse of a right triangle with acute angle 37° and adjacent side 11.

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(37°) = 11/x

Solving for x, we find ...

  x = 11/cos(37°) ≈ 13.77

The measure of side x is 13.77 units.

Compatible numbers are numbers that are close in value and can be easily divided or multiplied mentally. These numbers are used to make estimation in mathematical calculations easier and quicker. By rounding numbers to compatible numbers, calculations become simpler, and  errors are minimized.

For example, if you need to divide 26 by 5, you can use compatible numbers by rounding 26 to 25 and 5 to 4. Then, you can easily divide 25 by 4 to get an estimate of the quotient as 6.25. Compatible numbers can also be used in multiplication, addition, and subtraction.

Using compatible numbers is particularly helpful when performing mental calculations or when there is no calculator available.

To estimate the quotient of 420 divided by 21 using compatible numbers, we can round 420 to 400 and 21 to 20. Then, we can divide 400 by 20 to get an estimate of the quotient:

420 ≈ 400

21 ≈ 20

400 ÷ 20 = 20

30(1-cos2) is the evaluated line integral along the given positively oriented curve.

Green's theorem is mostly utilized to evaluate the line integral of a single direction and a curved plane. The link between a line integral and a surface integral is demonstrated by this theorem. It is connected to several theorems, including the Gauss theorem and the Stokes theorem.

To integrate the derivatives in a certain plane, one uses Green's theorem. This thesis can be employed to transform a given line integral into a surface integral, double integral, or conversely.

One of the four calculus foundational theorems, all 4 of whom are intimately connected to one another, is the Green's theorem.

How to solve?

By Green's theorem, we have

Answer:The area of the walkway around is 26 x + 16 as the sum of two terms

Step-by-step explanation:

The correct formula to multiply cell D5 by 105 and copy it to cell E5 would be A. =D5*105.

Calculating the sum of two or more numbers is the process of multiplication. 'A' multiplied by 'B' is how you express the multiplication of two numbers, let's say 'a' and 'b'. Multiplication in mathematics is essentially just adding a number repeatedly in relation to another number.

The formula =D5*105 is the correct formula to multiply the value in cell D5 by 105 and display the result in cell E5.

Let's break down the formula:

- D5: This refers to the value in cell D5, which is the number you want to multiply.

- *: This is the multiplication operator, used to multiply the value in D5.

- 105: This is the number you want to multiply cell D5 by.

So, when you enter the formula =D5*105 in cell E5, it will take the value in cell D5, multiply it by 105, and display the result in cell E5. If the value in cell D5 is, for example, 10, the formula will calculate 10 * 105 = 1050 and display the result 1050 in cell E5.

By copying the formula from cell E5 to other cells, it will adjust the cell references accordingly. For example, if you copy the formula to cell E6, it will update to =D6*105, multiplying the value in D6 by 105. This makes it easier to apply the same formula to multiple cells without having to rewrite it manually.

The length of the line segment AB such that PQ is the reflection of AB will be 6 units.

A line section that can connect two places is referred to as a segment.

A line segment is just part of a big line that is straight and going unlimited in both directions.

If we reflect any curve about the x-axis then only the y coordinate changes its sign (x,y) → (x,-y).

Given PQ is a reflection of AB and P(2,-2) and Q (8,-2)

Therefore, A(2,2) and B(8,2).

The length of AB will be,

The measurement of ∠STU is 20°.

Define Angle

When two rays are connected at their endpoints, they form an angle in geometry. We refer to these rays as the angle's sides or arms.

Components of an Angle

An angle is composed of the arms and the vertex as its two basic components:

Given, ∠STU = \((\frac {1}{4} x+8)\)°

∠UTV = x+2°

Given, that the line TV bisects ∠STU,

∠STV = ∠UTV

Substitute their values,

\((\frac {1}{4} x+8)\)° = x+2°

Calculating,

\(\frac{1}{4}x-x\) = 2-8

\(-\frac{3}{4}x\) = -6

x = \(-6*(-\frac{4}{3})\)

x = 8

So, we know that:

∠STU = ∠STV + ∠UTV

          =  \((\frac {1}{4} x+8)\)° +( x+2°)

          =  \((\frac {5}{4} x+10)\)

Now, substitute the value of x,

∠STU =  \((\frac {5}{4} )*8\)°+10°

          = 10° + 10°

          = 20°

Therefore, the measure of ∠STU is 20°.

Step-by-step explanation:

they are counting by 2s      10,12,14,16,18

Hope this helps!

Answer:

18

Step-by-step explanation:

It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8

y = 2 * 5 + 8

y = 10 + 8

y = 18

5 = 18

Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

The area enclosed by the x-axis and the curve defined by x = 1 et and y = t - t² can be found using calculus. The enclosed area is approximately 1.5 square units.

To determine the area, we need to integrate the curve between the points where it intersects the x-axis. The curve intersects the x-axis when y = 0. So we set t - t² = 0 and solve for t, which gives us t = 0 or t = 1.
Next, we need to calculate the integral of the absolute value of the curve between the points of intersection with the x-axis. This is done by integrating |y| with respect to x over the range from x = 0 to x = 1.To perform the integration, we substitute the given expressions for x and y into the integral. The integral evaluates to 1.5, which gives us the enclosed area.
Therefore, the area enclosed by the x-axis and the curve is approximately 1.5 square units.

Therefore, the slope of the secant line between x1 = 4 and \(x^2 = 7\) for the function \(f(x) = 2x^2\) is 22.

We have the function \(f(x) = 2x^2\) and the values x1 = 4 and x2 = 7.

We can use the formula for the slope of the secant line between x1 and x2:

slope \(= \frac{(f(x_2) - f(x_1))}{(x_2 - x_1)}\)

First, we need to find f(x1) and f(x2):

\(f(x1) = 2x_1^2 = 2(4)^2 = 32\\f(x2) = 2x_2^2 = 2(7)^2 = 98\)

Substituting these values into the formula, we get:

\(slope = \frac{(98 - 32) }{(7 - 4)} = \frac{66}{3} = 22\)

The slope of a secant line is a measure of how steeply a curve is rising or falling between two points.

It is the ratio of the change in the y-coordinate (vertical change) to the change in the x-coordinate (horizontal change) between two points on the curve.

Given two points (x1, y1) and (x2, y2) on a curve, the slope of the secant line between them is given by the formula:

\(slope = \frac{(y_2 - y_1)}{(x_2 - x_1)}\)

The mean of the 10 sales amounts for store A is $40,000.

Step-by-step explanation:

Given;

yˆ= −3,000 + 1.2x ...................... (1)

Where;

x = sales amounts each day at store A or the mean of the 10 sales amounts for store A = ?

yˆ = sales amounts each day at store B or the mean of the 10 sales amounts for store B = $45,000

Substituting y = 45,000 into equation (1) and solve for x, we have:

45,000 = −3,000 + 1.2x

45,000 + 3,000 = 1.2x

48,000 = 1.2x

x = 48,000 / 1.2

x = 40,000

Therefore, the mean of the 10 sales amounts for store A is $40,000.
