Answer:
125feet
Step-by-step explanation:
Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.
The arrow reaches the maximum height at dh/dt = 0
dh/dt = -32t + 80
0= -32t+80
32t = 80
t = 80/32
t = 2.5secs
substitute t = 2.5 into the formula;
h = -16t^2 + 80t + 25
h = -16(2.5)^2 + 80(2.5) + 25
h = -16(6.25)+225
h = -100+225
h = 125
Hence the maximum height the arrow reaches is 125feet
I’m pretty sure the angle in 53 degrees

Answer:
74/100 OR 37/50
Step-by-step explanation:
First add everyone together since its asking for no cold / everyone.
41 + 15 + 12 + 5 + 21 + 6 = 100
Then add to gether the total of people without a cold.
41 + 12 + 21 = 74
Next you just put the ratio in order which in this case would be no cold / everyone then if possible simplify.
74/100 = 37/50
