Answer:

Rectangular Pyramid volume = 84 ft^3
Rectangular Prism volume = 840 ft^3
Total volume = 924 ft^3

Step-by-step explanation:

Rectangular pyramid volume = 1/3 bh
Rectangular pyramid volume = 1/3 (84)(3)
Rectangular pyramid volume = 1/3 252
Rectangular pyramid volume = 84

Rectangular prism volume = l • w • h
Rectangular prism volume = 12 • 10 • 7
Rectangular prism volume = 840

840 + 84 = the total volume of the composite

The total volume of the composite = 924

posledela

Answer:

f(2) = 28

Step-by-step explanation:

\rm f(x) = 8 {x}^{2}  + 4x - 12

\rm Evaluate \:  8 x^2 + 4 x - 12 \:  where  \: x = 2: \\  \\  \rm \implies f(2) = 8 \times {2}^{2}  + 4 \times 2 - 12 \\  \\   \rm \implies f(2) = 8 \times 4 + 8 - 12 \\  \\   \rm \implies f(2) = 32 - 4 \\  \\   \rm \implies f(2) = 28

For all values of x,
Nana76 [90]

Answer:

For f(x) = 2x + 3 and g(x) = -x 2 + 1, find the composite function defined by (f o g)(x)

(f o g)(x) = f(g(x))

= 2 (g(x)) + 3

= 2( -x 2 + 1 ) + 3

= - 2 x 2 + 5 Given f(2) = 3, g(3) = 2, f(3) = 4 and g(2) = 5, evaluate (f o g)(3)
