Log base 4 of 32 is equal to 5/2.
What a log is looking for is what number do we have to raise 4 to in order to get 32. Since it is not an exact multiply of 4, we have to look for fractions. Since we know that 2 can multiply directly to 32, we would simply take the square root of 4. This can be done by raising 4 to the 1/2.
Now that we have 2, we know that raising that to the 5th power would give us 32. So we'll take that answer and the 1/2 from before and multiply them together to get the final answer.
5*1/2 = 5/2.
It would be C)15.75 miles because you divide it to get 2 hrs and divide again to get an hour then again to get half and hour and you add on the last number and 2nd to last so.. 42/2 is 21/2 is 10.5/2 is 5.25 add 10.5 and 5.25 is 15.75 which is 15 and 3/4 miles :)).
Answer:
Y=4x-3
Explanation: If we look 2 = 5 We can do 4(2)= 8 -3 = 5 So that the answer and 4(4)= 16-3 = 13 so these are the Y so this is the answer!
