The coordinate of point R and S are (4,3)and(1,6)what is the distance between the point

1 answer:

3 0

Let the points R( 4,3) be
$x1andy1$
and S(1,6) be X2,y2.
using pythogras theorem RS
$rs^{2} ={ x2 - x1} {?}^{2} + {y2 - y1} {?}^{2}$

=3
${3}^{2} + { - 3}^{2}$
$\sqrt{18}$

$4\sqrt{2}$

Suppose you buy a CD for $1000 that earns 2.5% APR and is compounded

labwork [276]

The early withdrawal fee on this account is $6.25

Step-by-step explanation:

Suppose you buy a CD for $1000

It earns 2.5% APR and is compounded quarterly
The CD matures in 5 years
Assume that if funds are withdrawn before the CD matures, the early withdrawal fee is 3 months' interest

We need to find the early withdrawal fee on this account

∵ The annual interest is 2.5%

- Change it to decimal

∵ 2.5% = 2.5 ÷ 100 = 0.025

∴ The annual interest rate is 0.025

∵ The interest is compounded quarterly

∴ The interest rate per quarter = 0.025 ÷ 4 = 0.00625

∵ The early withdrawal fee is 3 months' interest

∵ You buy the CD for $1000

∵ A quarter year = 3 months

∴ The early withdrawal fee = 1000 × 0.00625 = $6.25

The early withdrawal fee on this account is $6.25

What ordered pair is a solution for y-4=7(x-6)

777dan777 [17]

The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)

Step-by-step explanation:

The point-slope form of a linear equation is:

$y-y_{1}=m(x-x_{1})$ , where

m is the slope of the line
$(x_{1},y_{1})$ is a point on the line

Any point on the line is a solution for the equation of the line

The solution of an equation is the values of x and y which make the left hand side is equal to the right hand side

∵ The equation is y - 4 = 7(x - 6)

- Compare the equation by the point-slope form above

∴ m = 7

∴ $x_{1}$ = 6 and $y_{1}$ = 4

- That means point (6 , 6) lies on the line

∴ Point (6 , 4) is a point on the line which represents the

given equation

∵ Any point on a line is a solution of the equation of that line

∴ (6 , 4) is a solution of the equation

The ordered pair (6 , 4) is a solution for y - 4 = 7(x - 6)

PLS HELP 44 pts! Meg plotted the graph below to show the relationship between the temperature of her city and the number of peop

aev [14]

Answer:

Okay so I am not positive but I will try to help you out. Okay so the line of best fit would positive. Because it is all going up. The approximate slope is 3/4 Because slope is change in y over change in x. The y intercept of the line of best fit would be (0,0). This is because when drawing the line you can see that it would intercept the y-axis at zero. My steps taken were basically just looking at it and peicing everything together. If you want to get more involved with slope you could pick to coordinates which I will include and do change in y over change in x.

My points I will pick are (1,1) and (5,2)

2-1/5-1=3/4

therefore approximate slope is 3/4

Like I said I am not positive but I am just trying to help out in some way.

If something is incorrect please inform me. If this helps also please inform me.

Solve equation 3(n - 5) = 7 - 2(n + 1)

AlladinOne [14]

Answer:

n= 4

Step-by-step explanation:

3 multiplied by n is 3n.

3 multiplied by -5 is -15.

so 3n-15= 7-2(n+1)

7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.

3n-15=7-2n-2

then move the variables to one side and numbers to the one side.

3n+2n=15+7-2

*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.

so 5n=22-2

5n=20

5 multiplied by 4 is 20 so n is going to be 4.

N=4
