ANSWER

EXPLANATION
We want to determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5].
The average rate of change of f(x) over the interval [a,b]:

If the average rate of change over the interval [3, 5] is 19, then;

From the to table f(5)=13






Answer:
C
Step-by-step explanation:
Volume in math means s the amount of space in a 3D object.
the formula is l × W × H
So you do 25 × 11.25 × 6
it equals to 1687.5.
Therefore, the volume of the brick is 1687.5
Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k =
must be equal for all points
(2, 5) → k =
= 2.5
(3, 7.5) → k =
= 2.5
(5, 12.5) → k =
= 2.5
(18, 8) → k =
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists
Answer:
46 cm
Step-by-step explanation:
If Susan can knit 1 cm per night and knits for 10 nights the is 10cm. Then you add the 10cm to the 36cm to get 46cm.
