Answer:

You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

M(x)=15x-x^2 solve for x

The maximum number of mosquitoes would exist if 7.5 inches of rain fell.


We can find that by looking for the maximum value in the equation. This value always falls at the vertex. The x-value of the vertex (which is what we are looking for) can always be found through the equation -b/2a, in which a is equal to the coefficient of x^2 (-1) and b is equal to the coefficient of x (15).


-b/2a

-(15)/2(-1)

-15/-2

What is the exponential function modeled by the following table?
steposvetlana [31]

Answer:

f(x)=9^{x-1}

Step-by-step explanation:

The general form of the exponential function is,

y=ab^x

The points on the graph will be,

(2,9),(3,27),(4,81)

Putting the points in the function,

9=ab^2  -----------------------------------1

27=ab^3  ---------------------------------2

Dividing equation 2 by equation 1,

\Rightarrow \dfrac{27}{3}=\dfrac{ab^3}{ab^2}

\Rightarrow 9=\dfrac{b^3}{b^2}

\Rightarrow b=9

Putting the value of b in equation 1,

\Rightarrow a(9)^2=9

\Rightarrow a=\dfrac{9}{9^2}

\Rightarrow a=\dfrac{1}{9}

Putting all the values,

\Rightarrow y=\dfrac{1}{9}\cdot 9^x

\Rightarrow y=9^{x-1}
