Answer:
39 feet
Step-by-step explanation:
From the question;
let length of ladder =x feet
height of ladder will be=x-3 feet
ground distance of ladder bottom to building=15 feet
Applying Pythagorean relation
a²+b²=c²
where a=15 feet b=x-3 feet and c=x feet thus
x²-15²=(x-3)²
x²-225=x²-6x+9
collect like term
x²-x²-225-9=-6x
-234= -6x
x= 39 feet length of ladder
distance from ground to top of ladder= 39-3=36 feet
The correct answer is Undefined
I just did this in pre-calculus and I’m positive it is correct
X - 1/2 because difference is subtraction

Answer:
7920.14
Step-by-step explanation:
The formula is y = a (1-r)^t
21000 (0.85)^6
0.85^6 = 0.37714951562
21000 (0.37714951562) = 7920.14
