a Answer:
Step-by-step explanation:
Any number raised to a fraction just means that you take the number to the power of the numerator of the fraction and then root it by the denominator of the fraction.
In
, we raise 624 to
and then root it by
which gives:
=

Answer/Step-by-step explanation:
There are actually two methods that can be used to calculate AC (x):
1. Using Pythagorean Theorem
2. Using Trigonometric Function
1. Using Pythagorean Theorem, we have:
x = √(15² + 20²)
x = √625
x = 25 units
2. Using Trigonometric Function:
Reference angle = 37°
Adjacent = 20
Opposite = 15
Hypotenuse = x
Apply SOH:
Sin 37 = Opp/Hyp
Sin 37 = 15/x
x × Sin 37 = 15
x = 15/sin 37
x = 24.9246021 ≈ 25 units (nearest whole number)
The answer to your question is (e)
Option A
The inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches
<em><u>Solution:</u></em>
Given that the equation of the line of best fit is:
y = -0.368x + 18.483
Where "y" is the total snowfall in her city
"x" is the average temperature
To find: Inches of snow fall during the month of January when the average temperature is 
Substitute x = 2 in given equation to find the total snowfall
y = -0.368x + 18.483
y = -0.368(2) + 18.483
y = -0.736 + 18.483
y = 17.747
Therefore inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches
