Step-by-step explanation:

all you have to do is plug in 2 to the equations as x and solve for y!

y = 7 - 3(2)

y = 7 - 6

y = 1

y = (2)^2 -1

y = 4 -1

y = 3

y = (18/(2))

y = 9

two complementary angels are in the ratio 4:5, find the angles.

Answers

Answer:

1 st angle = 40

2 nd angle= 50

Step-by-step explanation:

let 1 st angle be 4x and 2 nd angle be 5x4x +5x =90 9x =90 x=90/9 x= 10

Answer:

First angle = 40

Second angle = 50

Step-by-step explanation:

let 1st angle be 4x and 2nd angle be 5x

4x + 5x = 90 [Complementary means the sum of angles is 90]

=> 9x = 90

=> x = 90/9

=> x = 10

First angle = 4x = 4(10) = 40

Second angle = 5x = 5(10) = 50

( show your work ) The banner that football players run through is 18 feet high and 30 feet long. How much paper is needed to
construct a banner ?

Answers

Answer:

540 square feet worth of paper

Step-by-step explanation:

This is an area problem. Area is length multiplied by width. The provided length is 30 feet and the provided width is 18 feet. When they are multiplied, you get 540 square feet. Note that the height is the width in this context because if you laid the banner down, 18 would be the width. The banner is being held up, so the 18 feet is called the height.

I am the only toolkit function that has a start and end number for the range. I am also the only that is cyclic, meaning I repeat over and over.

Which toolkit function am I?

Answers

The Toolkit function that has a start and end number for the range and is also cyclic is ; The constant Function ( i.e. f(x) = a )

There are about (9) toolkit functions and some of these toolkit functions :

Constant function Cube root function Square root functionreciprocal squared functionreciprocal functioncubic and quadratic function Absolute value function

The common characteristics between the various toolkit functions is that they all have undefined domains ( i.e. ( - ∞ , ∞ ) or ( -∞, 0 ), and undefined ranges as well. while the only Toolkit function with a defined range is the Constant function { a, a }

The range for a Constant function starts and ends with the value of the given constant. i.e. { a, a }. while other functions have undefined range values.

Hence we can conclude that the Toolkit function with a start and end number for the range is the Constant function.

Answers

Answer:

X equals 8.

Step-by-step explanation:

The polygon in the question has 5 sides. However, it is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides. So for a five sided polygon, the size of the exterior angle is calculated as

360/5 which equals 72. Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

Subtract 264 from both sides of the equation

12X = 96

Divide both sides of the equation by 12

X = 8

The value of x in the given polygon is 8.

What is Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain

The polygon in has 5 sides.

It is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides.

So for a five sided polygon, the size of the exterior angle is calculated as

360/5 =72.

Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

12X = 96

Divide both sides of the equation by 12

X = 8

Hence, the value of x in the given polygon is 8.
