(a)
R(p) = -8p² + 1328p
R(50) = -8(50)² + 1328(50)
= -8(2500) + 66,400
= -20,000 + 66,400
= 46,400
R(70) = -8(70)² + 1328(70)
= -8(4900) + 92,960
= -39,200 + 92,960
= 53,760
R(90) = -8(90)² + 1328(90)
= -8(8100) + 119,520
= -64,800 + 119,520
= 54,720
(b) R(p) = -8p² + 1328p NOTE: maximum is the vertex
<em>a=-8, b=1328</em>
p = = 83
(c)
R(83) = -8(83)² + 1328(83)
= -8(6889) + 110,224
= -55,112 + 110,224
= 55,112
Answer:
2
Step-by-step explanation:
ist you have to lind the lcd of each fraction. that would be 10.
1/2x5/5=5/10 of the boys have brown eyes
1/5x2/2=2/10 of the boys have blue eyes
3/10=3/10 of the boys have hazel eyes
The question is asking to see how many more boys have brown eyes than hazel eyes.
Subtract 3/10 from 5/10
and that gives you 2/10

Answer:
f(3) = 36
Step-by-step explanation:
ƒ(x) = 5x^2 − 9x + 18
Let x =3
ƒ(3) = 5(3)^2 − 9(3) + 18
= 5*9 -27 +18
= 45 -27+18
=36
