Answer: -1
Raising one exponential expression to another exponent means you multiply the exponents together. We have 5*5 = 25 as the new exponent.
So we end up with (-1)^25 = -1
The rule I'm using is that -1 to any odd whole number power is going to result in -1. If the exponent was even, then -1 to that power would be 1.
So in short, the rule says
(-1)^n = -1 if n is an odd whole number
(-1)^n = 1 if n is an even whole number
Diameter of the bigger semi-circle is 15 m
circumference of the bigger semi-circle = πd = 15π
diameter of the smaller semi-circle = 15 - 2(1.25) = 15 - 2.5 = 12.5 m
circumference of the smaller semi-circle = πd = 12.5π m
Total length of the segments between the two circles = 11(1.25) = 13.75 m
Total length of wrought iron used = 15π + 12.5π + 13.75 = 100 m
Answer:
x^2=-10
Step-by-step explanation:
x squared equals to negative 10
Answer:
5 seconds
Step-by-step explanation:
All you have to do is make a ratio.
10 yards = 5/3 seconds
10 * 3 = 30 yards
5/3 * 3 = 15/3 = 5 seconds
