Let <em>x</em> = 0.424242... . Then 100<em>x</em> = 42.424242... . So we can write
100<em>x</em> - <em>x</em> = 99<em>x</em> = 42.424242... - 0.424242... = 42
which means
<em>x</em> = 42/99 = 14/33
and so
11.424242... = 11 + 14/33 = 377/33

The maximum height is the y-coordinate of the vertex (x,y) of the parabola.
First find the x-coordinate using the formula:

Now plug the value into the equation and find the y-coordinate:

The maximum height is 36 feet.
Answer:
Step-by-step explanation:
Simplify the expression -4x^2(3x − 7).
A. -12x^3 + 28
<h2>B. -12x^3 + 28x^2<= your answer</h2>
C. -12x^3 − 28
D. -12x^3 − 28x^2
They are equal because
1 yd=3ft
25 yds= x feet
x= 25*3
feet=75
