percentages compare numbers in the numerator to 100 and the ratio that compares a number to 100 is logically called percent.
Answer:
h = 36.9 cm
Step-by-step explanation:
The function given to us is:
h(t) = 51 + 20 sin(225t)
Where h(t) is the function of the height in centimeters while t represents the time in seconds.
We have to find the height h(t) when the time is equal to 19 seconds.
Substitute t=19 into the given function
h(19) = 51 + 20 sin(225(19))
h(19) = 51 + 20 sin(4275)
h(19) = 51 + 20 (-0.7071)
h(19) = 51 + (-14,1421)
h(19) = 36.8579 cm
Rounding off to nearest 10th
h = 36.9 cm
Answer:
176 feet
Step-by-step explanation:
You will get the same answers but with more zeros. For example 7x20 is 140, and 7x2000 is 14,000 but with more zero's
