Answer: 10^(1/2)</h3>
When we use an exponent of 1/2, it is the same as a square root. The more general rule is
In this case, we plug in x = 10.
The use of a fractional exponent is handy when you want to deal with things like cube roots on a calculator. This is because
![\sqrt[3]{x} = x^{1/3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%20%3D%20x%5E%7B1%2F3%7D)
Many calculators don't have a button labeled ![\sqrt[3]{}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%7D)
but they have the button 
to allow fractional exponents.
Answer:
5: 1, 2, 4, 11, 22, 44
6: 1, 5, 25, 125
7: 1, 5, 17, 85
8: 1, 3, 13, 39
Answer:
15.7 cm
Step-by-step explanation:
Angle AD = 180°- 66.4°= 113.6° (considering 2x90°=180° on opposite side)
P= 2*3.14*7.9=49.6 cm
Arc AD= 49.6*113.6°/360°= 15.7 cm
Answer:
C is the dependent variable and r is independent
Step-by-step explanation:
Adriana can ride the bus any number of times she wants. No one is stopping her from doing that so 'r' becomes an independent quantity.
Whereas, the total cost for the bus rides depends on the number of times Adriana rides the bus and the relation is given as, C=1.25r
This is because it costs $1.25 each time she rides the bus in one direction
