A. ratio of areas = 2^2 /5^2 = 4/25
B 14^2 : 1 = 196:1
C. ratio of perimeters would be sqrt81 = 9 times
Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
Answer:
Zero
Step-by-step explanation:
Since the line is a horizontal line, the slope does not change. The slope is zero.
Answer:
9 years = .000000706$
Step-by-step explanation:
convert 7% to decimal 0 .07
17,500 x .07 = 1,225
1 year 1,225
2 year 85.75
3 year 6.0
4 year .42
5 year .029
6 year .002
7 year .000144
8 year .000010088
9 years = .000000706$
