Answer:
54 feet
Step-by-step explanation:
We can use proportions
1 inch 27 inches
--------- = ------------
2 feet x feet
Using cross products
1x = 54
The building is 54 feet
X² + y² - 4 x + 2 y = b
x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1
( x - 2 )² + ( y + 1 )² = b + 5
y - coordinate of the center of the circle is: y = - 1
b + 5 = r
b + 5 = 7
b = 7 - 5
b = 2
3² = x + 5. The equivalent equation to log₃(x+5) = 2 is 3² = x + 5.
In order to solve this problem we have to know about Logarithm.
Logarithm is defined as the exponent of a power with a certain base, that is, the number to which a given base must be raised to obtain a given result.
logₐ b = x ----------> aˣ = b
Solving for log₃(x+5) = 2 where a = 3, x = 2, and b = x + 5
3² = x + 5
