8 / 2 equals to 4
therefore 10 / 2 will be equal to 5
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
Third angle = 180 - (44 + 72) = 180 - 116 = 64 degrees answer
3/5 divided by -4/9
3/5 times the reciprical -9/4
-27/20=-1 7/20
