Answer:  The function of Rae's earnings : f(x)=60+5.25x

She would make $81 after 4 hours.

Step-by-step explanation:

Let x be the number of hours Rae works.

Given : Rae earns $60 for playing music on Saturday nights at the local coffee house. She makes an average of $5.25 in tips per hour.

Then , the function of Rae's earnings will be :_

f(x)=60+5.25x

Now, for x = 4 hours , we get

f(4)=60+5.25(4)=81

Hence, she would make $81 after 4 hours.

F(x) = 5.25x + 60

after 4 hrs..
f(4) = 5.25(4) + 60
f(4) = 21 + 60
f(4) = 81.......Rae would make $81 after 4 hrs

12. Find the surface area of each figure to the nearest tenth.
Zolol [24]

Answer:

  12a. 471.2 cm²

  12b. 60 m²

Step-by-step explanation:

Part A.

The surface area of each figure is the sum of the end area and the lateral area.

  <u>cylinder</u>

  S = (2)(πr²) +2πrh = 2πr(r +h)

  S = 2π(5 cm)(5 cm +10 cm) =150π cm² ≈ 471.2 cm²

__

  <u>triangular prism</u>

  S = (2)(1/2)bh + PL . . . . b=triangle base; h=triangle height; P=triangle perimeter; L=length of prism

  S = (4 m)(1.5 m) + ((4 + 2·2.5) m)(6 m) = (6 + 54) m² = 60 m²

_____

Part B.

Surface area is useful in the real world wherever products are made from sheets of material or wherever coverings are applied.

Carpeting or other flooring, paint, wallpaper are all priced in terms of the area they cover, for example.

The amount of material used to make containers in the shapes shown will depend on the area of these containers (and any material required for seams).
