Answer:
Object will reach the max height in 10 seconds.
Max. height is 1817.
It will hit the ground in 20 seconds.
Step-by-step explanation:
In order to find the x value which makes the function take its greatest value, you need to take the derivative of the function and equalize the result to 0.
h'(t)=-12t+120=0
t=10
The object will reach its maximum height in 10 seconds.
h(10) (maximum height) = 6.10.10+120.10+17= 600+1200+17=1817
Considering this is a parabola, time in total is two times more than the time passed until reaching the max. height.
10.2=20
Answer:
First drawing - answer is: D: DG, FG and DE
Second drawing - answer is: π (pi)
Third drawing - answer is: 70° ( If you mean on measure of central angle which is corresponing to the arc CB)
Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )
Step-by-step explanation:
For the second drawing
arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π
For the third drawing
∠CAB is peripheral angle of the central angle ∠CFB.
∠CFB= 2·∠CAB= 2· 35° = 70°
Good luck!!!
The answer is 161.70 N.
EXPLANATION
To change from mass to weight multiply by gravity (9.8 m/s^2)
Fw = m * 9.8 m/s^2
Fw = 16.5 kg * 9.8 m/s^2 = 161.70 N.
