emmasim [6.3K]

Answer: The area of the regions covered by grass is approximately 313.375 sq ft.

Step-by-step explanation:

Given: A company is building a new park in the shape of a circle with a 25 ft diameter.

Then radius = \dfrac{25}{2}=12.5\ ft

Required area = Area of circle - Area of rectangle + Area of triangle

Formula: Area of circle = \pi r^2

Area of rectangle = length x width

Area of triangle = 0.5 x base x height

Area of circle = (3.14)(12.5)^2=490.625\ \text{ft}^2

Area of rectangle = 20 ft x 10ft = 200 ft²

Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²

Required area = 490.625 -200+22.75 = 313.375 ft²

Hence, The area of the regions covered by grass is approximately 313.375 sq ft.

F(x) = 5x<br> G(x) = 3x + 5
Alja [10]

Answer:

f(g(x)) = 5(3x + 5) = 15x + 25

g(f(x)) = 3(5x) + 5 = 15x + 5

Step-by-step explanation:

Since you didn't say what you were trying to find, I'll give you a couple things you may have been trying to find.

f(g(x)) = 5(3x + 5) = 15x + 25

g(f(x)) = 3(5x) + 5 = 15x + 5
