Which number is irrational

Answer:

1. [tex]\frac{3}{8}[/tex]

2. [tex]\frac{1}{4}[/tex]

3a. [tex]-\frac{1}{4}[/tex]

3b. 3

3c. [tex]-\frac{4}{5}[/tex]

4. [tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}[/tex]

[tex]m = \frac{3-2}{-2-2}[/tex]

[tex]m = \frac{1}{-4}[/tex]

[tex]m = -\frac{1}{4}[/tex]

3b.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{-1 - 2}{-1-0}[/tex]

[tex]m = \frac{-3}{-1}[/tex]

[tex]m = 3[/tex]

3c.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{1 - (-3)}{-1-4}\\[/tex]

[tex]m = \frac{4}{-5}\\[/tex]

[tex]m = -\frac{4}{5}[/tex]

4.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

Answer:

x=65

Angle 1=65

Angle 2=115

Step-by-step explanation:

We know that angle 1 + angle 2 = 180. Writing it in terms of x, we get x + (x + 50)= 180. Then you have 2x+50=180. Subtracting 50 from both sides gives you 2x=130. Dividing both sides by 2, you get x=65. Angle 1 is 65 degrees. 180-65=115.

Answer:

-5<x<9

Step-by-step explanation:

Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:

3x+15<42

3x<27

x<9

We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:

3x+15=0

3x=-15

x=-5

so, -5<x

Put both parts together to get: -5<x<9

Answer:

B) a²-(2*4)

Step-by-step explanation:

Since we are looking for the gray area only, we need to find the total area of the figure, but subtract that from the area of the unshaded area.

The total area of the figure is a*a=a²

The area of the unshaded figure is 2*4=8 units^2

This means the gray area is a²-(2*4) units^2, making B correct

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

Step-by-step explanation:

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

Answer: = 40 . 24

Step-by-step explanation:

A triangular prism. The rectangular sides are 24 feet by 40 feet, 40 feet by 15 feet, and 40 feet by 15 feet. The triangular sides have a base of 24 feet and height of 9 feet.

2,001 square feet

2,376 square feet

2,592 square feet

4,320 square feet

Answer: b.

Step-by-step explanation: A triangular prism is the one which has 3 rectangular sides and 2 triangular sides. To find the surface area of a triangular prism, we have to find the surface area of 3 rectangular side and 2 triangular sides and add them up

Surface Area (rectangle) = Length · Width

Surface Area (triangle) = (1/2)(Base)(Height)

Rectangular side 1:

Length = 40 ft

Width = 24 ft

Surface Area = 40 · 24

Surface Area = 960ft

Rectangular side 2:

Length = 40 ft

Width = 15 ft

Surface Area = 40 · 15

Surface Area = 600ft

Rectangular side 3:

Length = 40 ft

Width = 15 ft

Surface Area = 40 · 15

Surface Area = 600ft

Triangular side 1:

Base = 24 ft

height = 9 ft

Surface Area = (1/2)(24)(9)

Surface Area = 108ft

Triangular side 2:

Base = 24 ft

height = 9 ft

Surface Area = (1/2)(24)(9)

Surface Area = 108ft

SURFACE AREA OF TRIANGULAR PRISM:

Add all surface areas found above

Surface area = 960 + 600 + 600 + 108 + 108

Surface area = 2376ft

  (a)  ∠HIK and ∠GFD

Step-by-step explanation:

In this geometry, there are only two pairs of alternate exterior angles:

  ∠HIK and ∠GFD

  ∠JIK and ∠EFD

Of these, only the first pair is among the answer choices.

__

Alternate exterior angles are ones that are outside the parallel lines, and on opposite sides of the transversal.

Answer:

The answer is 119

Step-by-step explanation:

Answer:

119

Step-by-step explanation:

There is a reason why the answer is 119

First, lets take a look at your perfect squares chart ( by tens )

10 x 10 = 100

20 x 20 = 400

30 x 30 = 900

40 x 40 = 1600

50 x 50 = 2500

60 x 60 = 3600

70 x 70 = 4900

80 x 80 = 6400

90 x 90 = 8100

100 x 100 = 10000

110 x 110 = 12100

120 x 120 = 14400

we know that 12100 < 14161 < 14400, so it has to be in between the square root of 110 and the square root of 120

111 x 111 = 12321

112 x 112 = 12544

113 x 113 = 12769

114 x 114 = 12996

115 x 115 = 13225

116 x 116 = 13456

117 x 117 = 13689

118 x 118 = 13924

119 x 119 = 14161

We found out that the square root of 119 = 14161

Therefore, the square root of 119 = 14161

Answer:

It is (a)

[tex]g(x) = ( { \frac{1}{4} x})^{2} [/tex]

Step-by-step explanation:

I hope that is useful for you :)

None of the given options are correct.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

The point (4,1) is on the graph of the function f(x) = x^2. That means f(4) = 1.

We want to find the equation of a new function g(x) that satisfies the condition g(4) = 1.

One possible equation for g(x) that meets this condition is:

g(x) = a(x - 4)² + 1

where a is some constant that we need to determine.

Since the graph of g(x) is a parabola, we know that it has the form y = ax^2 + bx + c. We can use the point (4,1) to find a:

g(4) = a(4 - 4)² + 1 = 1

Simplifying this equation, we get:

a = 0

Therefore, the equation for g(x) is:

g(x) = 1

So the correct answer is (none of the above), because none of the given choices matches this result.
