What is the slope of the line through (10-11) and (10,-2)?

Vera_Pavlovna [14]

We can use the points (10, -11) and (10, -2).

Slope formula: y2-y1/x2-x1

= -2-(-11)/10-10

= 13/0

Since the denominator is 0, the slope is undefined.

Best of Luck!

if i want the track to have a circumference of 400 feet what does the diameter of the track need to be?

natta225 [31]

Answer:

The diameter of the track needs to be 127.27 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The circumference of any circle is C = 2πr, where r is the radius

of the circle and π is the constant ratio between the

circumference and the diameter of the circle which

approximately is 22/7 or 3.14

- The diameter of any circle is twice its radius

* <u><em>Lets solve the problem</em></u>

- The circumference of the track is 400 feet

∵ The circumference = 2πr

∵ π = 22/7

∴ 400 = 2 × 22/7 × r

∴ 400 = 44/7 r

- Divide both sides by 44/7 to find r

∴ r = 63.63

∵ The diameter of the circle = 2r

∵ The radius = 63.63 feet

∴ The diameter = 63.63 × 2 = 127.27 feet

* The diameter of the track needs to be 127.27 feet

0.611 convert Decimal to percentage

diamong [38]

Answer:

0.611 = 61.1%

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

Calculate the percent value:

0.611 =

0.611 × 100/100 =

(0.611 × 100)/100 =

61.1/100 =

61.1%;

In other words:

1) Multiply that number by 100.

2) Add the percent sign % to it.

At the Denver International Airport, planes must clear a mountain that is 1000 feet tall that is a horizontal distance of 2800 f

Readme [11.4K]

Answer:

19 degrees

Step-by-step explanation:

Will have a triangle with horizontal distance being 2800, and vertical being 1000 feet. Angle between the horizontal and hypotenuse is what we are looking for.

Thus it's a tangent function.

SOH

CAH

TOA <-----

Tangent is the opposite / adjacent

So we will be looking at doing an Arctan to find the angle.

Arctan α = $\frac{1000}{2800}$ = 19.29 degrees. Round to the nearest whole degree would be 19 degrees due to being less than .50

Your answer is 19 degrees
