The time it will take the roller coaster to reach the ground is 171.65 seconds

<h3>Function and values</h3>

Given the roller coaster’s height given by the following parameters

h = –0.025t² + 4t + 50

On the ground level, the height will be zero. Substitute h = 0 and determine the value of t

–0.025t² + 4t + 50 = 0

0.025t² - 4t - 50 = 0

Factorize

On factorizing the time it will take the roller coaster to reach the ground is 171.65 seconds

Step-by-step explanation:

<u>Step 1: Define Inequality</u>

15 < -5x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide -5 on both sides:                    -3 > x
  2. Rewrite:                                               x < -3

Here we see that any number <em>x</em> that is smaller than -3 would work as a solution to the inequality.

7) Write the decimal number as a fraction
(over 1)
2.18 = 2.18 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 2.18 × 10 × 10 × 10 = 2180
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 2180 / 1000

Simplifying our fraction

= 2180/1000

= 109/50

= 2  9/50

8)7 ^{-5}  =  \frac{1}{7^{5}}
