Answer:
1.06
Step-by-step explanation:
This log is to the base 5.
Write 5 5
and then raise the first 5 to the power log5(x + 5)
and the second 5 to the power x^2:
log5(x + 5) x^2
5 = 5
Then we have x + 5 = 5^(x^2)
We can approximate the solution by graphing x + 5 and 5^(x^2) as two separate functions and then reading off the approximate x-coordinate of the point of intersection. The calculator indicates that this coordinate is approximately 1.06 (which matches the fourth answer choice).
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
Answer:
He has written about 100 times as many words.
Step-by-step explanation:
In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.
12,580 - 125 = 12,455
Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.
12,455/125 = 99.64 times more, or rounded, about 100 times more.
T = 5.34 + 0.78m
T = 5.34 + 0.78 * 5
T = 5.34 + 3.9
T = 9.24
Tina was charged $9.24 at the car wash for 5 minutes.
