ANSWER
The constant of variation is 6.
EXPLANATION
The inverse variation equation is:
We want to find the constant of variation, when x=-3 and y=-2.
We substitute the values for x and y to get,
Multiply out the left hand keeping in mind that negative times negative yields a positive result.
This implies that;
Hence the constant of variation is 6.
There are 4 decimal places because there is 2 numbers after the decimal in 3.75 and 2 numbers after the decimal in .25
7(2/7) is 2.
-2(3/7) is -.8571428571.
subtracting a negative is the same as adding a positive, so
2+ .8571428571 is
2.857142857
Total sum / number of slopes. That’s the formula for averages
Answer:
C. $452115.44
Step-by-step explanation:
To solve this, we will follow the steps below;
first write down the formula for compound interest
A= P [ 1 + ]^nt
where A is the ending amount
P represent the principal
r represent the interest rate
n represent the number of compounding a year
t represent the time {in years)
from he question above
p= $318 000
r = 0.071
n = 4 since is quarterly
t= 5
we can now proceed to insert the values into the formula
A= P [ 1 + ]^nt
=318 000 [1+] ^4(5)
= $318 000 [1+] ^20
=$318 000 [1+0.01775] ^20
= $318 000 [1.01775] ^20
=$318 000× 1.421747
≈$452 115.44
He will have $452 115.44 in the account
