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:
30
Step-by-step explanation:
Q: (9/(3/10))
To solve, change the division sign to multiplication, and flip the denominator fraction.
(9/(3/10)) = 9 * (10/3)
Simplify. Multiply, then divide.
(9 * 10)/3 = (90)/3 = 30
30 is your answer.
