Answer:

Option A (4 \pi+26)\ in

Step-by-step explanation:

we know that

The perimeter of the figure is equivalent to the perimeter of a rectangle plus the perimeter of semicircle minus the length side of 8 inches

step 1

<u>Find the perimeter of rectangle</u>

the perimeter of rectangle is equal to

P=2(b+h)

we have

b=8\ in

h=9\ in

substitute

P=2(8+9)=34\ in

step 2

<u>Find the circumference of semicircle</u>

the of circumference of semicircle is equal to

C=\frac{1}{2}\pi D

we have

D=8\ in

substitute

C=\frac{1}{2}\pi (8)=4 \pi\ in

step 3

Find the perimeter of the figure

34\ in+4 \pi\ in-8\ in=(4 \pi+26)\ in

What is the solution to 3x²+x+10=0
e-lub [12.9K]

Answer:

x = - 1/6 + √-119/6, and, - 1/6 - √-119/6

Step-by-step explanation:

Using the quadratic formula which is: - b ± √b² - 4ac / 2a

a = 3, b = 1, c = 10

- 1 ± √1² -4 * 3 * 10 / 2 * 3

- 1 ± √1 - 120 / 6

-1 ± √-119 / 6

= -1/6 + √119/6,               or                  - 1/6 - √-119/6

A line passes through the point (2, -9) and has a slope of -9. Write an equation in point-slope form for this line.
Natali [406]

Answer:

y+9 = - 9x +18

Step-by-step explanation:

Line is passing through the point (2,\: - 9) =(x_1,\:y_1) and has slope (m) = - 9

General equation of line in point slope form is given as:

y-y_1 = m(x-x_1)

Therefore

y-(-9) = - 9(x-2)

y+9 = - 9x +18

This is the required equation of line in point slope form.
