Answer:
Height of vertical post relative to the horizontal is 6.3 ft
Height of vertical post above the roof (roofing sheets) is 4.0 ft
Step-by-step explanation:
Given the roof is 20° relative to the horizontal and the solar panel should be 38° relative to the horizontal, then finding the vertical support holding the back of the panel relative to the horizontal will be;
Apply the formula for sine of an angle as;
Sin of angle theta = opposite side length/hypotenuse
Sin 38° = O/8 where O is the length of opposite side of the angle
8*sin 38°=O
4.93 ft = O
Applying Pythagorean relationship to find the length from the bottom part of the panel to the vertical support relative to the horizontal will be;
a²+b²=c² where a=?, b=4.93 and c = 8
a²+4.93²=8²
a²=8²-4.93²
a=6.3 ft
Finding the height of the roof from the horizontal at 20° angle
Tan 20°= O/6.3
6.3 tan 20° = O
2.3 ft =O
Now finding the length of vertical post above the roof will be;
6.3-2.3=4.0 ft
The area of the circle is pie times radius squared. In this case the radius is 3.5 and that to the second power would be 12.25
(What your finding is a half circle so you can divide by two if needed but the total area would not change since you would be adding them together anyway)
The rectangle is 77 because the area is base times height.

Step-by-step explanation:
Cosecant is undefined at π/2, so we can rewrite this integral as:
lim(u→π/2) ∫ᵤᵖⁱ 35 csc(x) dx
lim(u→π/2) 35 ln│csc(x) − cot(x)│|ᵤᵖⁱ
lim(u→π/2) [35 ln│csc(π) − cot(π)│ − 35 ln│csc(u) − cot(u)│]
undefined
The integral diverges.
Answer:
Tamu burnt 5.66 calories per minute.
Step-by-step explanation:
Tamu ran for 30 minutes.
Calories burnt by Tamu = 170 calories
Unit rate =
Unit rate =
Unit rate = 5.66 calories per minute
Therefore,
Tamu burnt 5.66 calories per minute.
