So we are given the equation
y = 79.31(1.48)ˣ
Whereas the x represents the number of days <--- what you need to know
y is the final number you are going to get, does not matter for now
You are trying to find the number of bacteria on Day 8
Put 8 into x

1.48⁸ = 23.019
79.31 * 23.019 = 1825.667
Your answer would be A.
Answer:
7595.96 × 0.02 × x = y
Step-by-step explanation:
1. We start with $7595.96.
2. The interest is 2% or 0.02
3. Using this formula - P(Principle) x R(Rate) x T(Time) we pluck in the numbers.
4. 7595.96(Principle) x 0.02(Rate) x x(Time) = y(amount of money in the account after x years).
<span>f(x) = 0.3(4)x ------> f(x)=1.2x
As,
f(x)=y
So,
y=1.2x
re arranging x and y:
x=1.2y
y=1.2/x
f(-1)x= x/1.2
putting x=6:
f(-1) 6 = 6/1.2
</span><span>f(-1) 6 = 5</span>
Answer:
(3,0)
Step-by-step explanation:
We know that x intercepts is when the graph crosses the x-axis. Thus, all x intercepts have a y value of 0. (x, 0)
Therefore, we can set y to 0 to see when the graph equals y=0 or the x-axis.
2(0)-4x=-12
-4x=-12
x=3
There is no proper order to multiply in this case.
The answer is 72 either way!
