Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.
The answer is C. i hope this helps!!!
Hello.
1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]
Good luck to you!
Answer:
Equations weren't provided in the question but my answer is 3T=108
Step-by-step explanation:
t is oranges sold on Thursday.
f is oranges sold on Friday
If she sold the amount she sold on Friday is equal to 2x the amount on Thursday: 2t=f. But the total of 108 is both days added together. So she sold 2t on friday and 1t or ton thursday than you add it up like so: 2t+t=108 becasue 108 is the total. But 2t+t=3t so you get the final equation as 3t=108
