Answer:
Actual value after 5 years is £1344 more than John's value.
Step-by-step explanation:
Johns estimate:-
V = k/t (inverse proportionality) where V = value of the car and t = it's age.
When t = 2, V = £12,000:-
12,000 = k/2 giving k = 24,000
Therefore the value at 5 years of age, according to John's proposition is
V = 24,000 / 5 = £4,800
The actual value using the given depreciation is
12000(1 - 0.2)^3 = £6144
Difference is £1344
Answer:
G
Step-by-step explanation:
16 divided by 1/8 - 1
first, you would make 16 into a fraction, making the new equation 16/1 divided by 1/8 -1. you'd then flip 1/8 to 8/1 making the new equation 16 divided by 8 - 1. 16 divided by 8 is 2, and 2 - 1 = 1.
the answer is 1.
The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
The correct option is (A).
What is the average rate of change of a function?
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.
Using function notation, we can define the Average Rate of Change of a function f from a to b as:

The given function is
,
Now calculating the average rate of change of function from x = 1 to x = 2.

Now, calculate the average rate of change of function from x = 3 to x = 4.

The jump from m = 10 to m = 40 is "times 4".
So option (A) is correct.
Hence, The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
