balandron [24]

Answer

square root of 32

Step-by-step explanation:

in a right triangle we can use Pythagorean theorem to find B

C^{2} =A^{2}+B^{2}  \\\\  9^{2}=7^{2}+B^{2}   \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}we substitute C for 9 and A for 7

A company's profit (in millions of dollars) can be represented by x^2-6x+12, where x is the number of years since the company st
Sergeu [11.5K]
The function that models the profit of the company in million of dollars is:

P= x^{2} -6x+12

where x represents the number of years since the company started. We want to find when the profit of the company was $4 million. Setting P as 4 in above equation, we can find the value of x when the profit was $4 million.

4= x^{2} -6x+12 \\  \\ &#10; x^{2} -6x+8=0 \\  \\ &#10; x^{2} -2x-4x+8=0 \\  \\ &#10;x(x-2)-4(x-2)=0 \\  \\ &#10;(x-2)(x-4)=0 \\  \\ &#10;x=2, x=4

Thus, we can conclude that the profit of the company was $4 million in 2nd and 4th year
