Step-by-step explanation:
1.80/4= 0.45
2.70/6=0.45
5.40/12=0.45
0.45*20= 9$
Answer:
x = 1 ±√89
Step-by-step explanation:
We have the equation:
(x+7)(x-9) = 25
Using distributive property:
x(x-9) + 7(x-9) = 25
x²- 9x + 7x - 63 -25 = 0
x²- 2x - 88 = 0
To complete squares we need to add and subtract 1, as follows:
x²- 2x - 88 +1 -1 = 0
x²- 2x +1 -88 -1 = 0 (this is a perfect square)
(x - 1)² - 89 = 0
Solving for x:
(x - 1)² = 89
x - 1 = ±√89
x = 1 ±√89
The quotient of x and three is 3/x. quotient is a division term and when the dividend is divided by the divisor, the result is a quotient.
The given details follow the product rule. The different model of the car available are 756.
Given that:




The different possibility is calculated using the following product rule:

So, we have:


Hence, there are 756 different models available.

Solution
For this case we can use the following formula:

Where:
P= 400800 = present value
A= future value
r= 0.055 interest rate
n= 4, number of times that the interest is compund in a year (quarterly)
t= 4 years
Replacing we got:

then the interest would be:
