Answer:
Volume = 113.1 cubic cm
Step-by-step explanation:

Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]
In short, Option C is your answer!!!!
Let me know, if you have some doubt.
Answer:
100% B
Step-by-step explanation:
Answer: 80 g
Step-by-step explanation:
Given
The frosting is made of cream cheese and Powdered sugar in the ratio of 3:2.
If 120 g of cheese is used
Assume the quantity of powdered sugar is x
So, we can write the ratio as

So, 80 g of powdered sugar is used.

Answer: -6</h3>
======================================================
Explanation:
Plug in x = 1
f(x) = 17-x^2
f(1) = 17-1^2
f(1) = 17-1
f(1) = 16
Repeat for x = 5 to find that f(5) = -8
Now we'll use the formula below to find the average rate of change from x = a to x = b.

The average rate of change is -6
The formula is basically the slope formula, more or less. So that's why I used 'm' to represent the average rate of change.
The average rate of change on the interval [1,5] is the same as finding the slope through the lines (1, 16) and (5, -8)
