When a loan officer speaks to people about a loan for a certain principal, P, at a certain monthly rate, r, they always have to

balance two quantities, the monthly payment, m, with the number of payments, n, it takes to pay off the loan. These two vary inversely. All of these quantities can be related by the formula:

Answer:

M= \frac{Pr}{1-(1+r)^{-n}}

Step-by-step explanation:

When you take a loan, the amount collected is referred to as the Principal(P).

The loan is given at a certain rate(r) in this case a Monthly Rate for a period of n months. The Monthly payment is denoted using M.

All these variables are related by the function:

M= \frac{Pr}{1-(1+r)^{-n}}

Note that if the rate is given as an Annual rate, we divide by 12 to get the monthly rate required.

Solve each quadratic equation. Show your work 15. x2 + 3x = 10
OLEGan [10]
X² + 3x = 10

Convert to standard form.
x² + 3x - 10 = 0

factor x² = x * x
factor -10 = 5 * -2

(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0

x + 5 = 0               x² + 3x = 10
x = -5               -5² + 3(-5) = 10
                              25 - 15 = 10
                                     10 = 10

x - 2 = 0            x² + 3x = 10
x = 2               2² + 3(2) = 10
                             4 + 6 = 10
                                 10 = 10

Kathi and Robert Hawn had a pottery stand at the annual Skippack Craft Fair. They sold some of their pottery at the original pri
Vinil7 [7]

Answer:

The number sold at $12.50 is  25

The number sold at $9.50 is 62

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

x 12.50 + y 9.50=901.50

x+y= 87

Where

x= number of pottery pieces sold

y= number of pottery pieces sold at a decreased price  

Multiplying the second equation by 9.50, and subtracting the second equation to the first equation:

12.50 x + 9.50y = 901.50

-

9.50 x+ 9.50 y= 826.5

__________________

3 x = 75

Solving for x

x =75/3

x = 25

Replacing x=25 on any equation:

x+y= 87

25+y =87

y=87-25

y= 62

How many different arrangements can be made with ten pieces of silverware laid in a row if three are identical spoons, four are
LuckyWell [14K]

10 pieces of silverware laid in a row if 3 are identical spoons, 4 are identical forks, and 3 are identical knifes

The arrangement of 'm' objects on which 'n' objects are of same kind is \frac{m!}{n!}

Given: 10 pieces of silverware so its 10!

3 are identical spoons so its 3!

4 are identical forks so its 4!

and 3 are identical knifes so its 3!

Arrangements made = \frac{10!}{3!*4!*3!} = 4200
