On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) what is the length of SR

jenyasd209 [6]

the length of SR is $2\sqrt{17}$ .

Step-by-step explanation:

Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:

We know that , In a square there are 4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .

We know that distance between two points $Q(x_1,y_1),R(x_2,y_2)$ given by :

⇒ $QR = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Two points given are $Q(7,0), R(5,-8)$ :

⇒ $QR = \sqrt{5-7)^2+(-8-0)^2}$

⇒ $QR = \sqrt{(2)^2+(-8)^2}$

⇒ $QR = \sqrt{4+64}$

⇒ $QR = \sqrt{68}$

⇒ $QR = 2\sqrt{17}$

But QR=SR , Therefore , the length of SR is $2\sqrt{17}$ .

A salesperson at a jewelry store earns 5% commission each week. Last week, Jarrod sold $640 worth of jewelry. How much did he

Aleksandr-060686 [28]

Answer:

$32

Step-by-step explanation:

To find the commission, multiply the rate by the sales:

commission = 5% × $640 = $32

He made $32 in commission.

Additional comment

Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.

5% = 5/100 = 0.05 = 1/20

Then 5% × $640 = $640/20 = $64/2 = $32.

Which is an equation of the line with slope that contains the point (6, 4)?

Vesna [10]

Answer:

y=x-2

Step-by-step explanation:

x=6 and y=4, so simplest equation is y=x-2

You can have infinity lines with the point (6,4). Another example is $y=\frac{1}{2} x+1$
