Answer: $1800\text{ feet}$

Step-by-step explanation:

Given : Hot air balloons generally descend at a rate of 200 to 400 feet per minute.

Also, Four balloons descend 200 feet per minute for 9 minutes.

Then, the total change in altitude for all 4 balloons will be :-

$200\times9=1800\text{ feet}$

Hence, the total change in altitude for all 4 balloons will be : Balloon descends 18 feet in 4 minutes.

Rewrite the function by completing the square.<br> f(x) = x2 – 10x + 44<br> +<br> f(x) = (x+

iVinArrow [24]

Answer:

$f(x)=(x-5)^{2}+19$

Step-by-step explanation:

we have

$f(x)=x^{2}-10x+44$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-44=x^{2}-10x$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$f(x)-44+25=x^{2}-10x+25$

$f(x)-19=x^{2}-10x+25$

Rewrite as perfect squares

$f(x)-19=(x-5)^{2}$

$f(x)=(x-5)^{2}+19$
