Answer:
(b) c2+6x+9=16
(e) (x+)2=16
Step-by-step explanation:
average rate of change is the slope (of the line) between the two coordinates
f(t) = -16t² + 48t + 100
f(3) = -16(3)² + 48(3) + 100 = -144 + 144 + 100 = 100 (3, 100)
f(5) = -16(5)² + 48(5) + 100 = -400 + 240 + 100 = -60 (5, -60)
m = 
= 
= 
= -80
Answer: -80 ft/sec
Answer:
y=6x+28
Step-by-step explanation:
y-y1=m(x-x1)
y-4=6(x-(-4))
y-4=6(x+4)
y=6x+24+4
y=6x+28
Given:
(3x^4 - 2 + 8x^3 ) + (7x^3 - 6 + 7x^4 )
Add like terms together ( same variables and exponents )
3x^4 + 7x^4 +8x^3 + 7x^3 -2 - 6
10x^4 + 15x^3 - 8
Answer :
10x^4 + 15x^3 - 8
<em>q(x)=8x-7</em> is your equation.
When x = 4
Plug in 4 for x
q(4) = 8(4) - 7
Follow PEMDAS. Multiply 8 with 4
q(4) = 32 - 7
Subtract
q(4) = 25
(D) 25 is your answer
hope this helps
