66.

Naddik [55]

Answer: 530.66 units²

Step-by-step explanation:

$Area_{(circle)}=\pi r^2\qquad and\qquad r=\dfrac{diameter}{2}\\\\\\\implies Area_{(circle)}=\pi \bigg(\dfrac{diameter}{2}\bigg)^2\\\\\\\text{It is given that the diameter = 26:}\\A=\pi\bigg(\dfrac{26}{2}\bigg)^2\\\\\\.\quad =\pi \cdot 13^2\\\\\\.\quad =169\pi\\\\\\.\quad =\large\boxed{530.66}$

What is the trigonometric ratio for sin Z ?

Schach [20]

In all right triangles, the ratio between a leg and the hypothenuse is the sine of the angle opposite to the leg.

So, in your case, we have

$\sin(Z) = \dfrac{XY}{XZ}$

In order to find XY, we have

$XY = \sqrt{XZ^2-YZ^2} = \sqrt{1600-1024}=\sqrt{576} = 24$

So, the ratio for the sine is

$\sin(Z) = \dfrac{XY}{XZ} = \dfrac{24}{40} = \dfrac{3}{5}$

Solve for 52=4(8m-5)-8(m-6)

ira [324]

Answer:

m = 1

Explanation:

1. Given: 52 = 4(8m - 5) - 8(m - 6)

2. Distributive property on the two binomials: multiply 4 times each term inside the first binomial and multiply - 8 times each term inside the second binomial:

52 = 32m - 20 - 8m + 48

3. Combine like terms: 32m and -8m are a pair of like terms; - 20 and + 48 are other pair of like terms:

52 = 24m + 28

4. Subtraction property of equality: subtract 28 from both sides:

52 - 28 = 24m

5. Simplify:

24 = 24m

6. Division property of equality: divide each side by 24

24/24 = m

7. Simplify:

1 = m

8. Symmetric property:

m = 1

What is the y and x intercept for f(x)=3x-2 find f(-5)

masya89 [10]

Answer: The y- intercept is -2. The x-intercept is 2/3

The attachment shows the solutions.

Step-by-step explanation: The y-intercept is the "b" term in the slope-intercept form of the equation. To find the x-intercept, substitute 0 for the output and solve for x.

0 = 3x -2 . Add 2 to both sides

2 = 3x . Divide both sides by 3

2/3 = x the x-intercept is 2/3

To find f(-5) substitute -5 for x and solve.

f(-5) = 3(-5) -2

f(-5) = -15 -2

f(-5) = -17
