joey wants to buy $4,000 vehicle with 10% down for three years at 12% interest. What will his monthly payment be?

Nataly [62]

Answer:

$119.57

Step-by-step explanation:

We have to find present value of annuity to find the monthly payment.

Given,

Present value, PV = $4,000

Down payment = $4,000 × 10% = $400

Remaining present value = $(4,000 - 400) = $3,600

Interest, i = 12% = 0.12

As we need monthly payment, the interest rate will be monthly = 0.12/12 = 0.01.

Number of period, n = 3

monthly payment, m = 12

We know,

Present value of annuity = PMT × $\frac{1 - (1 + \frac{i}{m})^{-n*m} }{\frac{i}{m} }$

$3,600 = PMT × $\frac{1 - (1 + \frac{0.12}{12})^{-3*12} }{\frac{0.12}{12} }$

or, $3,600 = PMT × 30.1075

or, PMT = $119.57

Monthly payment should be $119.57

A rectangular piece of plywood has a diagonal that measures three times the width. The length of the plywood is three feet more

Karolina [17]

Answer:

The length of diagonal is 4.922 feet.

Step-by-step explanation:

Let the width be = w

Let the diagonal be = d

Let the length be = l

Given is that the diagonal measures three times the width, this gives: $d=3w$

Also given is the length of the plywood is three feet more than the width. This is : $l=x+3$

Now, in terms of x we get:

Width = x

Length = (x+3)

Length of Diagonal = 3x

Now applying Pythagorean Theorem

$a^{2}+b^{2}=c^{2}$

$x^{2}+(x+3)^{2}=(3x)^{2}$

$x^{2}+x^{2}+6x+9=9x^{2}$

Solving this we get,

$-7x^{2}+6x+9=0$

We will use quadratic formula to solve this and get the answer,

x = 3/7 +/- (12√2) / -14

x = 1.64075 or x = -0.783612(neglect this negative value)

So, x = 1.64075 feet

Now length of diagonal is 3x = 3*1.64075 = 4.922 feet

So, length of diagonal is 4.922 feet.
