Answer:

Step-by-step explanation:
When you multiply two exponents together with the same base, the exponents get added
Here the base is the same ie b
So 
The constants multiply in the usual sense so 7(-9) = -63
Answer is 
Answer:
About 4.2 ft
Explanation:
The area of the traingle can be calculated in two ways.

where width = 4.4 ft and length = 13.6 ft.
Putting in the values for width and length gives

The other way that the area can be calculated is

where height = vertical length and base = 14.3 ft; therefore.

This must equal the area of the triangle we found above; therefore,


dividing both sides by 7.15 gives


which is our answer!
Answer:
use Pythagoras theorem
the missing side is base
Step-by-step explanation:
pythagoras theorem
h^2 = p^2 + b^2
73^2 = 48^2 + b^2
5329 = 2304 + b^2
5329 - 2304 = b^2
3025 = b^2
√3025 = b
55 = b
Answer:
35
Step-by-step explanation:
For this question do 27 squared which is 729 + 22 squared which is 484 then add them to get 1213 then square root 1213 to get 34.8281495345 which rounded to the nearest inch would be 35
Answer:
1.54
Step-by-step explanation:
The cotangent value is referred to as the reciprocal or the opposite of a given tangent value. Cotangent is also referred to as it's short form called cot
Mathematically, Cotangent (cot) = 1/tan
In the above question, we are given a value where:
tan = 33°
Cotangent (cot) = 1/tan 33°
Cotangent (cot) = 1.5398649638
We are told to approximate to the nearest hundredth
= 1.54
