If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
any questions?
We are given an exponential function:
f (x) = 2e^(3x)
The standard form of an exponential function is Aoe^(bx),
where Ao is the initial value of the function
b is the growth factor of the function
To graph the function, assign values of x then solve for the values of y corresponding the values of x.
This question is very confusing, because the answer is 100%. The box is not even over 70% and is no way of telling since none of the values are shown.
Answer:
Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Let x = original price
Knowing that multiplying the original price and the discount is the discount price. We formulate:
x(1 - 0.40) = 179.94
x(0.60) = 179.94
x = 179.94/0.60
x = 299.9
That is about 300 of the original price.
