One side of a square has endpoints (4.7) and (-3,5). What is the perimeter of the square?

Mathematics

Goryan [66]3 years ago

Answer:

= 4√53 units

that is option(a)

Step-by-step explanation:

all sides of the square are of the same length

so if we get the length if this side, we can calculate its perimeter

there's this formula,

<u>side length between two points, let's say A(x, y) and B(p, q), is equal to </u>

\mathsf{ \sqrt{ {(x - p)}^{2} +  {(y - q)}^{2}  } }

so here we go,

the same points A and B here are

(4, 7) and (-3, 5)

therefore, side length :-

= \mathsf{ \sqrt{( {7 - 5})^{2}  +  {(4 - ( - 3))}^{2} } }

=  \mathsf{ \sqrt{ {2}^{2} +  {7}^{2}  } }

=  \mathsf{  \sqrt{4 + 49}  }

=   \mathsf{\sqrt{53} }

the side length comes out to be <u>√(</u><u>53</u><u>) </u>

now perimeter of a square is

4 × side length

= 4√53 units

What is 50% of $68? Show all of your work. Use the percent proportion model shown below to set up the equation before you calcul
Natali5045456 [20]

Answer:

$34

Step-by-step explanation:

50% is half of 100%

(Because 50% x 2 = 100%)

Thus, half the money ($68) to find 50%.

So, 68÷2 = 34

Final answer is $34

Or

50/100 x $68 =$34

Answer:

D

-3 * (-4) matches, as well as the powers (I guess you wanted to communicate that these are powers, but it would also be correct if these where factors)

How to write an equation of a horizontal line through a point?
satela [25.4K]
Y= y1

replace the y1 with the ordinate ( the y-part) of the point you are going thru

example a horizontal line going through the point (7,12) would be y=12

Work out an equation of the straight line with gradient 3 that passes through the point with coordinates (2, 4).
Gnom [1K]

Answer:

The answer is

\huge \boxed{y = 3x - 10}

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (2, 4) and the slope is 3

The equation of the line is

y - 4 = 3(x - 2) \\ y + 4 = 3x - 6 \\ y = 3x - 6 - 4

We have the final answer as

y = 3x - 10

Hope this helps you
