The correct question is
<span>Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem. Gavan must paint a cube-shaped box. The edge length of the box is 2 1/2 feet. What is the surface area of the box?

we know that
[surface area]=6*s</span>²
s is the edge length of the cube

in this problem
s=2 1/2 ft------> (2*2+1)/2-----> 5/2 ft
[surface area]=6*(5/2)²----> 6*(25/4)----> 75/2 ft²-----> 37 1/2 ft²

the answer is
37 1/2 ft²

Consider the multivariable function f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}f ( x , y , z ) = x 3 −
Lelu [443]

Answer:

f\left(2,3,1\right)=\bold{14}

Step-by-step explanation:

Given the function:

f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}

To find:

The value of f(2, 3, 1) = ?

Solution:

f(2, 3, 1) means the values of x, y\ and\ z as:

x=2\\y=3\\z=1

Let us put the given values in the given function and let us solve for it:

\Rightarrow f\left(2,3,1\right)=\dfrac{2^3-2.5\times 3^2+\frac{1}{2}}{1\left(2-3\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-2.5\times 9+0.5}{1\left(-1\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-22.5+0.5}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{-14}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\bold{14}

Therefore, the answer is:

f\left(2,3,1\right)=\bold{14}

Which equation represents a population of 370 animals that increases at an annual rate of 11% ?
Olegator [25]

The equation represents a population of 370 animals that increases at an annual rate of 11% is .

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1.

Given that,

A population of 370 animals that increases at an annual rate of 11%

a = 370, r = 11%

p=a(1+r)^{t}

  = 370(1+0.11)^{t}

p  =  370(1.11)^{t}

Hence, The equation represents a population of 370 animals that increases at an annual rate of 11% is .
