What is the area of the figure?
rewona [7]

Answer:

57 square feet

Step-by-step explanation:

Split the boxes into two parts.

One box measuring 11.5 ft long and 3 ft wide. (Box A)

The second box measuring 7.5 ft long and 3 ft wide. (Box B)

Area (figure) = Area of box A + Area of box B

Area of box A

3 × 11.5 = 34.5 ft²

Area of box B

3 × 7.5 = 22.5 ft²

Area of figure = 34.5 + 22.5

Area of figure = 57 ft²

Identify the equation of the circle that has its center at (-16,30) and passes through the origin
dangina [55]

Answer:

(x+16)²+(y-30)²=1156

Step-by-step explanation:

We have given:

center at (-16,30). It means h = -16 and k=30

and it passes through the origin (0,0)

Thus the  radius will be distance between (-16,30) and (0,0)

r=√(-16 - 0)²+(30-0)²

r=√256+900

r²=(√1156)²

r²=1156

Now apply standard equation of circle:

(x-h)²+(y-k)² = r²

(x+16)²+(y-30)²=1156

Thus the equation is (x+16)²+(y-30)²=1156 ....

Which is the inverse of the function f(x)=1/3x+5 ?
PtichkaEL [24]
To find the inverse of a function, switch the x and the y and then solve for the new y.  Like this: x= \frac{1}{3}y+5.  Subtract 5 from both sides to get x-5= \frac{1}{3}y and then multiply both sides by 3.  3(x - 5) = y.  B is your choice.
