PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of s
1 answer:
Answer:
<h3>H. 150 ft</h3>Step-by-step explanation:
Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;
Hence the height of the golf after 2.5 seconds is 150ft.

Answer:
- <em><u>The reduction is 8.6%</u></em>
Explanation:
Call F the full monthly pension of a person retiring at 62.
If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:
Where r = 6 / 100 = 0.06, and t = number of years after retirement.
<u>For retirement at 65.5</u>:
- t = 65.5 - 62 = 3.5
<u>For retirement at 67</u>:
- t = 67 - 62 = 5
<u>Percent reduction of people who retire at 65.5 compared to what they would receive at 67</u>:
Answer:
1300 cm = 13 m
Step-by-step explanation:
We need to find meters in 1300 cm.
We know that,
1 m = 100 cm
1 cm = (1/100) m
It means,
Hence, there are 13 m in 1300 cm.
