Answer:
10. (5,-10) and (2,-4)
11. The maximum height of the ball is 16 feet and it occurs 1 second after the ball is kicked.
Step-by-step explanation:
11. f(x)=-16x^2+32x
0=-16x^2+32x
0=x^2-2x
0=x(x-2)
f(x)=-16^2+32x
f(x)=-16 X (1)^2+32 X (1)
= -16+32
=16
Rationalizing the denominator involves exploiting the well-known difference of squares formula,
We have
so that
Rewrite 16 and 32 as powers of 2, then simplify:
So we have <em>A</em> = 8, <em>B</em> = 2, <em>C</em> = 4, and <em>D</em> = 7, and thus <em>A</em> + <em>B</em> + <em>C</em> + <em>D</em> = 21.
Answer: Jason will record 6 songs on day 3.
