Answer: Diameter = 4 cm

Step-by-step explanation:

20π = (π)(r^2)(5)

divide by 5 * π

4 = r^2

find the square root of both sides

2 = r

2 * 2 = d

4 = d

The value of x that satisfies the equation 4/3=x+10/15

kenny6666 [7]

For this case we must find the value of "x" that meets the following equation:

$\frac {4} {3} = x + \frac {10} {15}$

We subtract $\frac {10} {15}$ on both sides of the equation:

$\frac {4} {3} - \frac {10} {15} = x\\\frac {15 * 4-3 * 10} {3 * 15} = x\\\frac {60-30} {45} = x\\- \frac {30} {45} = x$

We simplify:

$x =\frac {6} {9}=\frac{2}{3}$

Finally, $x =\frac {2} {3}$

Answer:

$x =\frac {2} {3}$

If (-2,11)and(9,22) are two anchor points on the trend line, then find the equation of the line

Elza [17]

Answer:

The equation of the line is $y=x+13$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,11) and (9,22)

substitute

$m=\frac{22-11}{9+2}$

$m=\frac{11}{11}$

$m=1$

step 2

Find the equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=1$

$point\ (-2,11)$

substitute in the equation and solve for b

$11=(1)(-2)+b$

$11=-2+b$

Adds 2 both sides

$b=11+2\\b=13$

The equation of the line is

$y=x+13$

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. B = 46°, a = 12, b = 11

andreyandreev [35.5K]

*Hint: The Law of Sines is Sin A/a = Sin B/b = Sin C/c

In order to solve this equation, you will have to use this equation:

A= sin^(-1)[a sinB/b]
A= sin^ (-1) [12 (sin 46°) / 11]
A = sin^ (-1) [8.632077604/11]
A = sin ^(-1) [0.7847343276]
A = 51.69611349

Therefore, Sine A would be about 52°
