otez555 [7]

Answer:

$(x_4,y_4) = (1.5,-2\frac{1}{2})$

Step-by-step explanation:

Given

$(x_1,y_1) = (-3,3)$

$(x_2,y_2) = (1.5,3)$

$(x_3,y_3)=(-3,-2\frac{1}{2})$

Required

Determine the coordinate of the 4th point

From the given parameters, we can see that the rectangle is either horizontal or vertical.

This is because:

$x_1 = x_3 = -3$

and

$y_1 = y_2 = 3$

To calculate the fourth point, we simply make use of:

$x_2 = x_4$ and $y_3 = y_4$

Substitute 1.5 for x2 in $x_2 = x_4$

$1.5= x_4$

$x_4=1.5$

Substitute -2 1/2 for y3 in $y_3= y_4$

$-2\frac{1}{2}= y_4$

$y_4 = -2\frac{1}{2}$

Hence, the 4th point is:

$(x_4,y_4) = (1.5,-2\frac{1}{2})$

Mr. Steiner purchased a car for about $14,000. Assuming his loan was

djverab [1.8K]

Answer:

$415.18

Explanation:

The calculation of the present value of a cash flow or other income stream that produces $1 in income over so many periods of time.

DATA

Amount borrowed = $12,500

Annual interest rate = 12.00%

Monthly interest rate = 1.00%

Period = 36 months

Let monthly payment be x

12,500 = x/1.01 + x/1.01^2 + x/1.01^3 … + x/1.01^35 + x/1.01^36

12,500 = x * (1 - (1/1.01)^36) / 0.01

12,500 = x * 30.107505

x = 12,500/30.107505

x = 415.18

The monthly payment is $415.18

Here is a set of numbers , 10,10,10,10,11,12,13,15,17,find the mode, the median , the mean b there is a mistake in the set of nu

Georgia [21]

First, find the mode, median, and mean of the given set of numbers.

Mode

The mode is the number that shows up frequently within the given set. In this case, it will be 10, as it shows up 4 times, 3 times more than any other number.

Mode: 10

Median

The median is the number that is in the middle of the given set. In this case, there are 9 numbers, and so the 5th given number is your median:

10 , 10 , 10 , 10 , 11 , 12 , 13 , 15 , 17

Median: 11

Mean

The mean is combining all numbers within the given set and dividing by the amount of numbers in that said set:

(10 + 10 + 10 + 10 + 11 + 12 + 13 + 15 + 17)/9 = 108/9 = 12

Mean: 12

Find the slope -intercept equation of the line containing (1,-4) and having slope m=3

laiz [17]

Y=3x -7

you can figure this out or check if it’s correct by using point slope formula,
which is : y-y1=m(x-x1)
y1=-4, x1=1, and m=3 :)
