Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
6 = b
c= 8
a=?
now u just replace
a^2 + 6^2 = 8^2
a^2 + 32 = 64
a ^2 = 64-32
a^2 = 32
a = 5.65685424949
if you rounded
a = 5,7
Since the rate is constant, the growth of the height of the helicopter follows a linear pattern. The helicopter has an initial quota of 40ft, so that would be the constant term. The linear terms's coefficient is the rate of growth, so 21 ft/s. So, if is the number of seconds passed from when the observation started, we have
Which means that, if , the height is
Let y be the total number of the bike that are produced
let x be the number of hours
equation:
y = 15x
Area = 3.14(r^2)
Area = 3.14(4^2)
Area = 3.14(16)
Area = 50.2
The answer is C
