Tree height / 14 = 6 / 3.5
tree height = (14 * 6) / 3.5
Answer:
The rate of change for the given function is 6.
Step-by-step explanation:
Given function is:

The interval on which we have to find the rate of change is:
1≤x≤2
Here
a = 1
b = 2
We have to find the values of function on both points
Putting 1 in place of input (x)

Putting x = 2

The rate of change is calculated by using the following formula

Hence,
The rate of change for the given function is 6.
Answer:
21 kWh
Step-by-step explanation:
1. Subtract 25% from the original amount.
25% of 28 kWh is ...
0.25 × 28 kWh = 7.00 kWh
Subtracting this from 28 kWh, we find the usage after reduction to be ...
28 kWh - 7 kWh = 21 kWh
__
2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...
(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh
__
Mario must reduce his usage to 21 kWh or less.
Here is your answer
12m-6
REASON:
6(2m-1)
Multiply 6 with both the terms in bracket, we get
6×2m - 6×1
= 12m-6
