Eddie built the ramp shown to train his puppy to do tricks. What is the surface area of the ramp. The dimensions are 20,20,20,23

mamaluj [8]

Answer:

3775 in²

Step-by-step explanation:

The surface area of the ramp :

Area of rectangle = 20 * 23 = 460 in²

Area of rectangle = 25 * 23 = 575 in²

Bottom rectangle = 60 * 23 = 1380 in²

For the trapezium: (front and rear)

1/2 (base 1 + base 2) * height

Base total = 20+ 20+ 20= 60

1/2(60)*15 = 450 in²

Total surface Area :

(460 + 460 + 575 + 1380 + 450 + 450) in² = 3775 in²

If f(x) = 3x2 and g(x) = x+2, find (f•g)(x).

Alecsey [184]

Since you have provided me with • symbol I must assume it's about function multiplication, but since standard keyboard doesn't have the function composition symbol $\circ$ I must assume you meant either.

1. Case you meant multiplication.

$(f\cdot g)(x)=3x^2\cdot(x+2)=\boxed{3x^3+6x^2}$

2. Case you meant composition.

$(f\circ g)(x)=f(g(x))=f(x+2)=3(x+2)^2=\boxed{3x^2+12x+12}$

Hope this helps. Next time please use LaTeX to format your equations so that others can give you answers as well.
