The ball hits the ground at 0 seconds or 2.5 seconds.

h represents the height of the golf ball after x seconds. The height is given by:

h(x)=-4.8x(x-2.5)

h(x) = -4.8x² + 12x

The time taken for the ball to reach the ground is at h(x) = 0, hence:

0 = -4.8x² + 12x

4.8x² - 12x = 0

x(4.8x - 12) = 0

hence x = 0; or 4.8x - 12 = 0

x = 0; or x = 2.5

Therefore the ball hits the ground at 0 seconds or 2.5 seconds.

b=1/12 or just 12

Step-by-step explanation:

combine like terms

1/3b +12=16

subtract 12 on both sides

1/3b=4

divided both sides with 1/3

b= 12 or 1/12

A recipe called for the ratio of sugar to flour to be 10 : 3 if you used 70 ounce of sugar how many ounces of flour would type n
scZoUnD [109]

10 : 3 goes to 70 : x

How to solve? Well...

What gets you from 10 to 70 using multiplication?

70 divided by 10 is 7. So... 7!

So multiply the ratio by 7.

10 : 3 turns into 70 : 21

If you used 70 ounces of sugar, you would need to use <u>21 ounces of flour.</u>
