Answer:
7 feet long
Step-by-step explanation:
This set up will give a right angle triangle where;
Length of the ladder is the hypotenuse = x
The distance of the ladder to the house is the adjacent = 3 feet
Angle of elevation theta = 72 degrees
Using the CAH in trigonometry identity;
cos theta = adjacent/hypotenuse
cos 72 = 3/hyp
hyp = 3/cos72
hyp = 3/0.4258
hyp = 7.05 feet
Hence the ladder is approximately 7 feet long
Answer:
$71.61
Step-by-step explanation:
66/22 = 3
3 · $1.87 = $5.61
$66 + $5.61 = $71.61
OR
$23.87 · 3 = $71.61
Sorry if this is wrong!
Answer:
5^3 y^5
125 y^5
Step-by-step explanation:
5y^3/(5y)^-2
Distribute the exponent in the denominator
5y^3/(5 ^-2 y^-2)
A negative exponent in the denominator brings it to the numerator
5y^3 5 ^2 y^2
Combine like terms
5 * 5^2 * y^3 5^2
We know that a^b * a^c = a^(b+c)
5^(1+2) * y^( 3+2)
5^3 y^5
125 y^5

Answer: c
Step-by-step explanation:
You have to find the area of the base, step 2 multiply by the height. Then multiply length and radius in a circle of a base. The correct answer is C. use the diameter to find the radius of the cylinder to find the volume.
