djyliett [7]

Answer:

$\frac{16}{15}$

Step-by-step explanation:

The number of stride Jim takes to walk a mile is $\frac{5280}{2\frac{1}{2}}=2112$ strides

The number of strides Jeffrey takes to walk a mile is $\frac{5280}{2\frac{2}{3}}=1980$ strides

Hence, ratio of number of strides of Jim to number of strides of Jeffrey is:

$\frac{2112}{1980}=1\frac{1}{15}$

Explain why (–4x)^0 = 1, but –4x^0 = –4.

Nastasia [14]

Any number raised to power zero = 1.

Note that 0 raised to power 0 is not 1, it is undefined.

Therefore:

(-4x)⁰ = 1

For the second part -4x⁰ = :

x⁰ = 1, -4x⁰ = -4*(1) = -4

This is true on the assumption that x is not equal to zero.

I hope this explains it.
