Hi There!

Eliminate C and D because when you are putting numbers into scientific notation the number can not be greater than 10.

8.4 x 10^-7 is the same as dividing 8.4 by 10 seven times which equals 0.00000084 which is not equal to the decimal form given in the question.

8.4 x 10^-8 = 0.000000084

Answer: B) 8.4 x 10−8

Hope This Helps :)

Answer and Step-by-step explanation:

The area of a circle:

$A = \pi r^{2}$

d = 2r

Plug in the values.

A = $\pi 7^{2}$

A = 49 $\pi$

58 = 2r

r = 29

$A = \pi 29^{2}$

A = $841\pi$

If u can help with this question, the options for both x' s are -8,-7,-6,-5,-4,-3,-2,-1,1,2,3,4,5,6,7,8

Simora [160]

1x + 1y = 100....multiply by -3/8
3/8x + 7/8y = 2000

no need to multiply the other equation by anything....the x's will cancel because one will be -3/8x and one will be 3/8x

What is the slope of the line that passes through (3, −7) and (−1, 1)?

Art [367]

Answer:

<h2>The answer is - 2</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, −7) and (−1, 1)

The slope is

$m = \frac{1 - - 7}{ - 1 - 3} = \frac{1 + 7}{ - 4} = - \frac{8}{4} = - 2 \\$

We have the final answer as

Hope this helps you
