Answer:
4:14, 6:21, 8:28
Step-by-step explanation:
The formula for compound interest is A=P(1+r/n)^nt, where n is the number of times an item is being compounded over the length of t, an amount of time, r is the rate of increase, and P is the principle amount (initial amount).
Our Principal, or initial amount is 600,000 and our rate of change is found by
dividing any number in the sequence by another number that is placed lower in the sequence, For example:
<u>r=69000/60000=1.15</u>
We are not given n, so our equation is 600,000(1.15)^n-1
:)
This is just one of many ways for this to be done
36.78 can also be written as 36 and 78/100 or 3678/100
2.4 can be written as 2 and 4/100 or 204/100
so we have 3678/100 ÷ 204/100
to divide fractions, you just have to flip the second fraction and multiply across
3678/100 * 204/100
750312/10000
Simplified that would be 75 and 312/10000
hope this helped
Answer:
Step-by-step explanation:
Given
Perpendicular to: y = x - 7
Passes through (-2,-6)
Required
Find the equation
An equation has the form:
Where
In 
Since the required equation is perpendicular to , then the relationship between their slopes is:
Substitute 1 for m
The equation is then calculated using:
Where
So, we have:
