What is the distance between (-5,6) and (4, 2)?

Sergeu [11.5K]

Answer:

9.85 units

Step-by-step explanation:

Let the distance between given points be d.

$\therefore \: d = \sqrt{ {( - 5 - 4)}^{2} + (6 - 2)^{2} } \\ \hspace{16 pt} = \sqrt{ {( - 9)}^{2} + (4)^{2} } \\ \hspace{16 pt} = \sqrt{ {81} + 16 } \\ \hspace{16 pt} = \sqrt{97 } \\ \hspace{16 pt}= 9.8488578 \\ \red{ \bold{ \therefore \: d =9.85 \: units }}\\$

What line would be parallel to 8x-2y=7 with a point of 12,1

SOVA2 [1]

Answer:

$y = 4x - 47$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Parallel lines:

When two lines are parallel, they have the same slope.

8x-2y=7

Placing into the format, we have thtt:

$2y = 8x - 7$

$y = 4x - \frac{7}{2}$

Slope of 4.

This means that the desired line has the following equation:

$y = 4x + b$

Point of (12,1)

This means that when $x = 12, y = 1$

We use this to find b.

$y = 4x + b$

$1 = 48 + b$

$b = -47$

So, the line has the equation:

$y = 4x - 47$

In the figure, angle A measures 41° and angle D measures 32°. What is the measurement of angle E?

Jlenok [28]

Interior angles of a triangle, when added, = 180
so < A + < B + < C = 180
41 + 90 + < C = 180
131 + < C = 180
< C = 180 - 131
< C = 49

< C + < D + < E = 180.....because when added they form a line
49 + 32 + < E = 180
81 + < E = 180
< E = 180 - 81
< E = 99 <======
