Mashutka [201]
So, you basically plug the values into the formula you have been given. D divided by T gives you the average speed.
We know the distance D is 145 miles and the Time T is 2.5 hours.

So, 145/2.5=58

Chemists use pH as a measure of acidity or alkalinity of a solution. It uses the concentration of hydrogen ions H+ in a logarith
SpyIntel [72]

Answer:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Step-by-step explanation:

Given

f(d) = (0.5 * 10^{-4})^d

g(H+) = -log_{10}(H+)

Required

Find the composite function g(f(d))

We have:

g(H+) = -log_{10}(H+)

Substitute f(d) for H+

g(f(d)) = -log_{10}(f(d))

Substitute f(d) = (0.5 * 10^{-4})^d

g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)

Apply law of logarithm

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Hence, the function is:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})
