Answer:
16.30 ft ≈ 16 ft 4 in
Step-by-step explanation:
Please see the image attached. According to the figure, AB is the leaning flag. When the sun is directly overhead at noon, the shadow of the flag is the line AC in the figure. The length of AC is 5ft. The length of the string of plumb bob is 3ft and this is represented by the line XY. Y is the point of the plumb bob and this is at a distance of 11 in ( = 
ft from the base of the flag, i.e, AY = 0.92ft.
Now, the angle between the AB and AC is taken as ∅. In traingle AXY, tan(∅) = 
. In triangle ABC, for the same ∅, tan(∅) = 
. Therefore, tan(∅) = 
. Here, XY = 3ft, AY = 0.92ft, AC = 5ft.
Therefore, 
×5 = 16.30 ft ≈ 16 ft 4 in.
Answer:
2x2x2x5
Step-by-step explanation:
2x2x2x5 equals 40
Solution:
we are given that
Darlene wrote this proof of the identity (x + y)2 - (x - y)2 = 4xy.
we have been asked to find
Which of the following is a justification for Step 3 of her proof?
Step 3 of her proof is
As we can observe inside each of the paranthesis only like terms have been added. It mean the required justification is
C. Combining like terms
Volume of cone = 1/3 x pi x r^2 x h
where r = 5 ft and h = 16ft
Volume = 1/3 x pi x 5^2 x 16 = 400/3 π ft^3
