Delaney bought a crate for her puppy when it was 3 months old. The crate is in the shape of a rectangular prism. Since the puppy
Alika [10]

Answer:

The volume of the new crate is exactly 174.4% of the old crate.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism of dimensions x, y and z is given by:

V = xyz

She decided that the dimensions of the new crate needs to be increased by 40% of the original length.

Each dimension is increased by 40%, which means that each is multiplied by 1 + 0.4 = 1.4. So

V = 1.4x(1.4y)(1.4z) = (1.4)^3(xyz) = 2.744(xyz)

Percentage:

The new volume is 2.744 the original volume. Considering the original volume is 100% = 1, it increased by 2.744 - 1 = 1.744 = 1.744*100% = 174.4%.

The volume of the new crate is exactly 174.4% of the old crate.

Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).
stich3 [128]

Answer:

(g\cdot f) =  -3x^2-3

Step-by-step explanation:

f(x) = x^2 + 1

g(x) = -3

The problem state to multiply the function f and g so the symbol seems to be incorrect.

We actually want to calculate

g(x)  f(x) =gf(x) =  (-3)  \cdot (x^2+1)= -3x^2-3

Note

g\circ f(x)=g(f(x))=g(x^2+1)=-3
