Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ]
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus
average rate of change = =
= 34
Answer: 14
Step-by-step explanation:
Step 1: Substitute the x and y values:
Step 2: Find 4 to the power of 3.
4 x 4 x 4 = 64
Now find 2 to the power of 3
2 x 2 x 2 = 8
Step 3: Subtract the two values as mentioned in the equation:
64 - 8 = 56
Step 4: Now divide 56 by 4 as mentioned in the equation.
56 ÷ 4 = 14
And... 14 is the answer!
Hope this helps :)

Answer:
A.
Step-by-step explanation:
We are given,
The cost of one book = $2.25
Since, it takes $2.25 to buy 1 book.
The, for $10, we can get i.e.
= 4.44
Since, number of books cannot be in decimals.
So, the closest integer to 4.44 is 4.
Hence, we can buy 4 books from $10.
Now, according to the options:
A.
B.
C.
D.
Hence, we see that from the options, A is correct.
