Answer:

ANSWER

Not a factor

EXPLANATION

The given polynomial has equation:

According to the remainder theorem, if (x+5) is a remainder, then f(-5)=0.

Let us substitute x=-5 into the function and evaluate to see if it will simplify to zero.

Since the remainder is not zero, x+5 is not a factor of

after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)=

MArishka [77]

General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2

If x3= 27 and y3 =125, what is the value of y-x

Leno4ka [110]

Answer:

32 2/3

(32.6 repeating)

Step-by-step explanation:

29/3 is 9 (just make it not 3 Xs,) so x=9

125/3 is 41 2/3 so y= 41 2/3

41 2/3 - 9 = 32 2/3
