$8000 at 3% annually for 4 years

1 answer:

7 0

Here's the equation for one year:
0.03(8000) + 8000
For four years:
4(0.03(8000)) + 8000
0.12(8000) + 8000
To make it simpler/smaller:
1.12(8000) = 8960
You can make 960 more dollars, and you now have $8960

Edward is collecting data on the average length of lizards from head to tail for a particular generation. Initially, the average

Zina [86]

Answer:

The general form of a natural logarithmic function is f(x)=a In(x-h) +k. Since the initial average length of the lizards was 20 centimeters, one possible point (h+1,k) through which the function passes is (0,20).

In this case, h= -1 since h +1 = 0 and k = 20.

It follows that x - h = (-1) = x + 1.

So, the function takes the form f(x) = a In(x + 1) +20.

The average length of the lizards after 2 years is 22.197. So f(2) =22.197. We substitute this value into the function

Step-by-step explanation:

f(2) = a In(2 +1) +20

22.197 = a In(3) + 20

$\frac{2.197}{1.099}$ ≈ a

2 ≈ a

So the function that represents the average length of the lizards across this generation is f(x) = 2 In(x+1) +20
