Answer: 3.33% (choice B)
===================================================
Work Shown:
A = true value = 60
B = estimated or measured value = 62
C = percent error
C = ( |A-B|/A ) * 100%
C = ( |60-62|/60 ) * 100%
C = (2/60)*100%
C = 0.0333*100%
C = 3.33%
The result is approximate.
A. Answer: y = 32.913(1.126)ˣ
<u>Step-by-step explanation:</u>
You are given two coordinates (2, 53) and (9, 122). Use these to create a system of equations:
53 = a(b)² and 122 = a(b)⁹
122 = a(b)²· (b)⁷
122 = 53 · (b)⁷
1.126 = b
Substitute the b-value into either of the equations to solve for "a":
53 = a(1.126)²
32.913 = a
Input the a- & b-values into the general form of an exponential equation:
y = a(b)ˣ
y = 32.913(1.126)ˣ

B. Answer: 23 minutes
<u>Step-by-step explanation:</u>
Substitute y = 500 into the equation above to solve for x:
500 = 32.913(1.126)ˣ

Answer:
b^7/5
Step-by-step explanation:
The 5 is in front of the radical ,so it would go on the denominator.
