The height of flagpole is 12.5 feet.
Step-by-step explanation:
Given,
Height of woman = 5 foot
Shadow of woman = 6 feet
Ratio of height to shadow = 5:6
Shadow of flagpole = 15 foot
Height of flagpole = x
Ratio of height to shadow = x:15
Using proportion;
Ratio of height to shadow :: Ratio of height to shadow

Product of mean = Product of extreme

Dividing both sides by 6

The height of flagpole is 12.5 feet.

Answer:
3. C≈31.42
4.C≈94.25
Step-by-step explanation:
10 ÷ 2 =5
C=2πr
c=2 (3.14) 5
c= 2(3.14)15
Step-by-step explanation:
<u>Given:</u> [{36√(6) + 6^(5/2)} / (108×12)]² = 6ⁿ
<u>Asked:</u> Find the value of n = ?
<u>EXPLANATION</u><u>:</u>
Given that:
[{36√(6) + 6^(5/2)} / (108×12)]² = 6ⁿ
⇛[{(6)² * (6)^(1/2) * (6)^(5/2}/(36 * 3 * 12)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(36 * 36)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(6*6 * 6*6)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(6² * 6²)]² = 6ⁿ
⇛(6³⁻²)² = 6ⁿ
⇛(6¹)² = 6ⁿ
⇛6² = 6ⁿ
When an exponential has the same base on each side, then the exponents must be equal.
Therefore, n = 2.
<u>Answer</u><u>:</u> The Value of “n” for the given problem is 2.
