Answer:

3 $\sqrt{141}$

Step-by-step explanation:

Use the Pythagorean Theorem.

$37^{2}$ = $x^{2}$ + $10^{2}$

1369= $x^{2}$ +100

-100 -100

1269= $x^{2}$

$\sqrt{1269}$ = $\sqrt{x^{2} }$

The profit from a business is

GuDViN [60]

First of all we will understand the question!!

The question is saying that you are given a function and you have to find the value of x which will give the maximum profit... Lets solve it by finding the extrema using the vertex

 $\rm \: p(x) = - 5 {x}^{2} + 30x + 8$ 

Identify the coefficients a and b of the quadratic function

 $\rm \: p(x) = { - 5x}^{2} + 30x + 8 \\ \rm \: a = - 5 \: and \: b \: = 30$ 

Since a<0, the function has the maximum value at x, calculated by substituting a and b into x=-b/2a

$\rm \: x = \frac{30}{ 2 \times (- 5)}$

Solve the equation for x

$\rm \: x = 3$

The maximum of the quadratic function is at x=3

Reggie is surveying a plot of land in the shape of a rectangle. The area of the land is 73,000 square meters. If the width of th

Ber [7]

You can start with the formula for area of a rectangle, then solve for the length.
area = length*width
73000 m² = length*(5025 m)
73000 m²/(5025 m) = length ≈ 14.53 m
