Answer:
40.5
Step-by-step explanation:
i multiplied 30 with .25 which was 7.5
then i multiplied 30 with .1 which was 3
add those together 10.5

Answer:
The average rate of change over the interval [9,10] is greater than that over the interval [5,8] by 6490.
Step-by-step explanation:
The value of f(x) = 4052 for x = 9 and f(x) = 11014 for x = 10.
Therefore, the average rate of change of f(x) with respect to x over the interval [9,10] is given by
=
=
Now, the value of f(x) = 75 for x = 5 and f(x) = 1491 for x = 8.
Therefore, the average rate of change of f(x) with respect to x over the interval [5,8] is given by
=
=
Therefore, the average rate of change over the interval [9,10] is greater than that over the interval [5,8] by (6962 - 472) = 6490. (Answer)
Answer:
x = -172
Step-by-step explanation:
x + y = -11 and 161 - y = 0
hence using elimination method :
161 + x = -11
x = -11 - 161
x = - 172
