Answer:

Step-by-step explanation:

To find the slope of the line perpendicular, you take the reciprocal of the slope of the first line and multiply by -1. So a line with slope $\frac{1}{2}$ is perpendicular to a line with slope - $\frac{2}{1}$ .

In your case, the slope of the line perpendicular is going to be $-\frac{5}{2}$ . So yoo know your equation will look like y= $-\frac{5}{2}$ x+b. To solve for b, plug in the x and y-coordinates:

$-2=-\frac{5}{2}(2)+b$

b=3

So your final answer is y= $\bold{-\frac{5}{2}}$ x+3. Answer D is correct.

How to solve (8.76 x 109)(6.52 x 10-3)/13.27 x 105?

SVEN [57.7K]

Use PEMDAS:
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

First, start with the parenthesis:
(8.76 * 109)(6.52 * 10 - 3) / 13.27 * 105
(954.84)*(62.2) / 13.27 * 105

Then do ALL multiplication:
59,391.048 / 1,393.35

Now do all division:
42.62

So, your final answer is 42.62

Find the distance between the pair of points<br><br> (0,0)(6,8)

Ivahew [28]

A(0,0)
B=(6,8)

Distance formula

$\boxed{\sf AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

$\\ \sf\longmapsto \sqrt{(6 - 0) {}^{2} + {(8 - 0)}^{2} } \\ \\ \sf\longmapsto \sqrt{ {6}^{2} + {8}^{2} } \\ \\ \sf\longmapsto \sqrt{36 + 64 } \\ \\ \sf\longmapsto \sqrt{100} \\ \\ \sf\longmapsto 10$
