Answer:
d fasho
Step-by-step explanation:
Just try to form a triangle,so that we can apply "Trigonometric ratios"
In the final triangle of our figure,
Perpendicular = 32.5 - 6 = 26.5 Feet
Base = 110 Feet [ Given ]
Now, We know, Tan Ф = P / B
Tan Ф = 26.5 / 110
Tan Ф = 0.240
We know, Tan 13.5 = 0.240
So, Ф = 13.5
In short, Your Angle of Elevation would be 13.5 degrees
Hope this helps!
Answer:
one way x=2 and y=3 second way x=3 and y=3 third way x=1 and y=9
Step-by-step explanation:
- 3(2) = 6+3=12
- 3(3)=9+3=12
- 3(1)= 3+9=12
Answer:
the domain of the function = [0,12]
Step-by-step explanation:
Given that:
f(t) = 60 t - 5t²
at time t = 0
f(0) = 60 (0) - 5(0)²
f(0) = 0
the differential of f(t) is:
f(t)' = 60 - 10t
for the maximum height
f'(t) = 0
i,e
60 - 10t = 0
60 = 10t
t = 60/10
t = 6
Now, t = 6,
f(6) = 60(6) - 5(6)²
f(6) = 360 - 180
f(6) = 180
Hence, after 6 seconds, the stone is noticed to have raise to 180 m and 180 m drop after 6 seconds.
Hence, the domain of the function = [0,12]
