Please help.

kirill115 [55]

we have

$y=-16t^{2} +120$

we know that

When the apple hit the ground the value of y is equal to zero

Find the x-intercept of the function

equate the function to zero

$-16t^{2} +120=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$-16t^{2} =-120$

$t^{2} =-120/-16$

$t^{2} =7.5$

$t=(+/-)\sqrt{7.5}$

$t=(+/-)2.74$

therefore

<u>the answer is</u>

$2.74\ sec$

using a graphing tool

see the attached figure to better understand the problem

How do you solve this equation? 1/3|6x+5|=7

ycow [4]

|6x + 5| = 7 · 3

|6x + 5| = 21

6x + 5 = 21 (1st equation)

-6x + 5 = 21

(1st equation)

6x = 21 - 5

6x = 16

x = 8/3

(2nd equation)

-6x - 5 = 21

-6x = 21 + 5

-6x = 26

x = -13/3

so all of the solutions are;

x = -13/3, 8/3
