Answer:

\boxed {m = -\frac{4}{7}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to help you find the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First point: (x_{1}, y_{1})

Second point: (x_{2}, y_{2})

-Substitute the two given points onto the formula:

First point: (9, 10)

Second point: (2, 14)

m = \frac{14 - 10}{2 - 9}

-Solve for the slope:

m = \frac{14 - 10}{2 - 9}

m = \frac{4}{-7}

\boxed {m = -\frac{4}{7}}

Therefore, the slope is -\frac{4}{7}.

For a regular 30 sided polygon , what is the degree of rotation
Mashcka [7]
The measure of any interior angle of a convex regular n-gon is :
180 º - ( 360 º / n )

For a 30-sided polygon,
interior angle = 180 º - ( 360 º / 30 )
..................... = 180 º - 12 º
..................... = 168 º

It took team rise over run 1 2/3 hours to hike 4 2/3 miles. What is their average speed in miles per hour?
pogonyaev

To find their average miles per hour we can divide the total miles by the hour used:

4 2/3 ÷ 1 2/3

=4x3+2/3 ÷ 1x3+2/3

=14/3 ÷ 5/3

In division, when we switch the place of numerator and denominator, we can change it to multiplication which makes the calculation easier as we can factorize the numbers.

=14/3 x 3/5

Factorize 3 in both amounts:

=14/1 x 5/1

=14/5

=2.8 miles/hour

Therefore their average speed is 2.8 miles/hour.

Hope it helps!

A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid i
Temka [501]

Answer:

9.48

Step-by-step explanation:

Complete question

<em>A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the​ pyramid?</em>

To get the height of the pyramid, we will use pythagoras theorem.

slant height l is the hypotenuse

length of the base is the adjacent

height of the pyramid is the opposite

According to the theorem;

l² = h² + b²

90.1² = h² + 89.6²

8,118.01 = <em>h²+</em>8,028.16

h²= 8,118.01 - 8,028.16

h² = 89.85

h =√89.85

h = 9.48

Hence the height of the pyramid will be 9.48

<em>Note that the value of the slant height was assumed to solve the problem</em>.
