Answer:
Robbie Glider
<u></u>
Step-by-step explanation:
Given
<u>Melissa Glider</u>
<u>Robbie Glider</u>
See attachment for function
Required
Which reaches the greater maximum within the first 6 seconds
<u>Melissa Glider</u>
First, we calculate the maximum of Melissa's glider
Differentiate:
Equate to 0 to find the maximum
Divide through by 0.4
Solve for s using quadratic formula:
Where
So:
Split:
This implies that Melissa's glider reaches the maximum at 5.4 seconds or 1.9 seconds.
<em>Both time are less than 6 seconds</em>
Substitute 5.4 and 1.9 for s in to get the maximum
The maximum is 10.02ft for Melissa's glider
<u>Robbie Glider</u>
From the attached graph, within an interval less than 6 seconds, the maximum altitude is at 3 seconds
<em>Compare both maximum altitudes, 22ft > 10.02ft. This implies that Robbie reached a greater altitude</em>
Slope: -4
Y-intercept : (0, -10)
1 and 2 are the factors its a compatable number
Answer: -1
Step-by-step explanation: Let the integer be x
It's additive inverse = -x
= x / -x = -1
Answer:
Step-by-step explanation:
Given
0.2467467467........
We require 2 equations with the repeating part after the decimal point.
Let x = 0.2467467....
Multiply both sides by 10
10x = 2.467467... → (1)
Multiply both sides by 10000
10000x = 2467.467467.... → (2)
Subtract (1) from (2) to eliminate the repeating part
9990x = 2465 ( divide both sides by 9990 )
x = =
