30         2       1
---   = 7 -- = 7 --
4           4       2
Now this is how it should look like. You will divide 30/4 = 7.5 or 7 and 2/4

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 16 feet, and the ball 2 is dro

KATRIN_1 [288]

Answer:

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.

h1(t) = -16t^2 + 181

h2(t) = -16t^2 + 238

When does ball 1 reach the ground? Round to the nearest hundredth. seconds

Solve: -16t^2+181 = 0

-16t^2 = -181

t^2 = 11.3125

t = 3.3634 seconds

-----------------

When does ball 2 reach the ground? Round to the nearest hundredth. seconds

Compare the two functions to see which has a greater rate of change. Function 1

AleksAgata [21]

Function 2 has greater rate of change

Step-by-step explanation:

In order to find the rate of change we have to covert the given linear functions in slope-intercept form

Function 1:

$-2x+5y = 10$

Adding 2x on both sides

$-2x+5y+2x = 2x+10\\5y = 2x+10$

Dividing both sides by 5

$\frac{5y}{5} = \frac{2x+10}{5}\\y = \frac{2}{5}x +\frac{10}{5}\\y = \frac{2}{5}x+2$

Let m1 be rate of change of function 1:

$m_1 = \frac{2}{5}$

Function 2:

$-6x+3y = 18$

Adding 6x on both sides

$-6x+3y+6x = 6x+18\\3y = 6x+18$

Dividing both sides by 3

$\frac{3y}{3} = \frac{6x+18}{3}\\y = \frac{6x}{3} + \frac{18}{3}\\y= 2x+6$

Let m2 be the slope of function 2

$m_2 = 2$

As we can see that

$m_2>m_1$

Function 2 has greater rate of change
