Can somebody help me find the zeroes for this, algebraically?

To solve this algebraically, you can first factor out a 3:
3(x^2-2x-8)

Then, you can factor (I'm using guess and check) and my answer is -4 and 2:3(x-4)(x+2)

From here on, finding 0s is very easy. You just solve for x in the parentheses. So, the 0s are when x = 4, and x = -2. Remember, (4-4) = 0, and (-2+2) = 0, that's what you want.

the function h(t)=-16t^2+110t+72 models the height h, in feet, of an object above ground t seconds after being launched straight
Anettt [7]

Answer:

The initial height of an object above ground before being launched straight up in the air

Step-by-step explanation:

we have

h(t)=-16t^{2}+110t+72

we know that

The number 72 represent the y-intercept of the function

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The value of h when the value of t is zero

Therefore

The initial height of an object above ground before being launched straight up in the air

Write in y=mx+b form
DENIUS [597]

Step-by-step explanation:

b =-4 (y-intercept)

x =0

m = 0 (the line doesn't have a slope)

y = mx + c

y = 0(0) + (-4)

y = - 4
