Answer: 220 in^3

Step-by-step explanation:

Area of the rectangle: 20x8 = 160

Area of right triangle: 8x15/2 = 60

Side of right triangle = 8, as the pythagorean triple 8,15,17 states C:

Area of the figure: rectangle + triangle = 160+60 = 220

What are the domain and range of the function f(x)=(√x-7)+9?

Yanka [14]

Answer:

the domain of the function f(x) is $x\ge 7$

the range of the function f(x) is $f(x)\ge 9$

Step-by-step explanation:

Consider the parent function $y=\sqrt{x}.$

The domain og this function is $x\ge 0,$ the range of this function is $y\ge 0.$

The function $f(x)=\sqrt{x-7}+9$ is translated function $y=\sqrt{x}$ 7 units to the right and 9 units up, so

the domain of the function f(x) is $x\ge 7$

the range of the function f(x) is $f(x)\ge 9$
