Answer:

Its D (-2,-5)

Step-by-step explanation:

Point A rest in the (negative, negative) and you have to go along the x first which is -2 and down which is -5 so your answer in (-2,-5)

Also I just did this and is was correct.

Hope this helps!

The coordinates of point A is (-2,-5).

Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate). The origin is located at (0,0).

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.

From the given graph, we can see

Point A rest in the (negative, negative) and you have to go along the x first which is -2 and down which is -5 so your answer in (-2,-5)

The coordinates of point A is (-2,-5).

I think the answer might be y=4

Answer:

The inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]

Option A is correct option.

Step-by-step explanation:

For the function [tex]f(x)= (x+7)^5[/tex], Find [tex]f^{-1} (x)[/tex]

For finding inverse of x,

First let:

[tex]y=(x+7)^5[/tex]

Now replace x with y and y with x

[tex]x=(y+7)^5[/tex]

Now, solve for y

Taking 5th square root on both sides

[tex]\sqrt[5]{x}=\sqrt[5]{(y+7)^5}\\\sqrt[5]{x}=y+7\\=> y+7=\sqrt[5]{x}\\y=\sqrt[5]{x}-7[/tex]

Now, replace y with [tex]f^{-1} (x)[/tex]

[tex]f^{-1} (x)=\sqrt[5]{x}+7[/tex]

So, the inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]

Option A is correct option.

Answer:

Most reasonable: 16°, 20° and 22°

If Emma is very short, 25°

Step-by-step explanation:

This is trigonometry using Tangent and arc-tan

Tan=opp/adj

The length of the adjacent is 20 yards. The opposite lengths given are the bottom, 6 yards and the top, 10 yards. Assuming Emma is of average height, it seems reasonable to subtract about 1.7 to 1.9 yards, the distance of her eyes above ground level, for accuracy. But that may not be necessary, given the range of angles.

I subtracted 1.8, about 5'6"

Calculating tangent from the top:

8.2/20 = .41. arc-tan .41= 22.3°

tangent for the bottom:

4.2/20= .21 arc-tan .21 = 11.8°

If you are using a scientific calculator, once you have the ratio of the opp to adj in decimal form, use the tan- key then the decimal to convert to degrees.

Answer:

0<x<5

Step-by-step explanation:

I assume based on the question that you are in a geometry class, so you should understand this. Based on the triangle inequality theorem, the sum of two sides of a triangle are greater than the third side. Using this, we can say that x+3+3 should be greater than 5. since 3+3 is already six regardless of what x is, we know that as long as x is greater than 0 it meets this requirement. Also, if 5 and 3 are added they should be greater. 5+3=8, so x must be less than 5 for the 5 and 3 sides to be greater.

Answer:

19 boxes of tomatoes

Step-by-step explanation:

If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.

The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.

A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

Given:

Nancy has 7 boxes of tomatoes,

Each day, she picks another 2 boxes,

The equation which will represent the above phrase is shown below,

Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,

Assume the total number is y and the number of days is x then,

y = 7 + 2 × x

y = 2x + 7

Put the value of x = 6,

y = 2 × 6 + 7

y = 12 + 7

y = 19

Thus, she has a total of 19 boxes of tomatoes after 6 days.

Answer:

Supplementary angles

Step-by-step explanation:

Definition of supplementary angles :

"If the sum of two adjacent angles is 180°, angles are said to be supplementary angles."

m∠ABC + m∠CBD = 90° + 90° [Given]

m∠ABC + m∠CBD = 180°

Therefore, both the angles are supplementary angles.

Answer:

B = 34.2°

C = 58.2° or 121.8°

c= 10.6

Step-by-step explanation:

Step 1

Finding c

We calculate c using Pythagoras Theorem

c²= a² + b²

c = √a² + b²

a= 8, b = 7

c = √8² + 7²

c = √64 + 49

c = √(113)

c = 10.630145813

Approximately c = 10.6

Step 2

Find B

We solve this using Sine rule

a/sin A = b/sin B

A = 40°

a = 8

b = 7

Hence,

8/sin 40° = 7/sin B

8 × sin B = sin 40° × 7

sin B = sin 40° × 7/8

B = arc sin (sin 40° × 7/8)

B ≈34.22465°

Approximately = 34.2°

Step 3

We find C

Find B

We solve this using Sine rule

b/sin B = c/sin C

B = 34.2°

b = 7

c = 10.6

C = ?

Hence,

7/sin 34.2° = 10.6/sin C

7 × sin C = sin 34.2 × 10.6

sin C = sin 34.2° × 10.6/7

C = arc sin (sin 34.2° × 10.6/7)

C = arcsin(0.85)

C= 58.211669383

Approximately C = 58.2°

Or = 180 - 58.2

C = 121.8°

Answer:

C=105.8 degrees. c=12

Final Answer: [tex]b = -18[/tex]

Steps/Reasons/Explanation:

Question: Solve [tex]-21 = -9 + \frac{2}{3}b[/tex].

Step 1: Simplify [tex]\frac{2}{3}b[/tex] to [tex]\frac{2b}{3}[/tex].

[tex]-21 = -9 + \frac{2b}{3}[/tex]

Step 2: Regroup terms.

[tex]-21 = \frac{2b}{3} - 9[/tex]

Step 3: Add [tex]9[/tex] to both sides.

[tex]-21 + 9 = \frac{2b}{3}[/tex]

Step 4: Simplify [tex]-21 + 9[/tex] to [tex]-12[/tex].

[tex]-12 = \frac{2b}{3}[/tex]

Step 5: Multiply both sides by [tex]3[/tex].

[tex]-12[/tex] × [tex]3 = 2b[/tex]

Step 6: Simplify [tex]-12[/tex] × [tex]3[/tex] to [tex]-36[/tex].

[tex]-36 = 2b[/tex]

Step 7: Divide both sides by [tex]2[/tex].

[tex]-\frac{36}{2} = b[/tex]

Step 8: Simplify [tex]-\frac{36}{2}[/tex] to [tex]-18[/tex].

[tex]-18 = b[/tex]

Step 9: Switch sides.

[tex]b = -18[/tex]

f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5

Given :

A crafter is making a triangular flag.

She has two sides of length 24 inches and 36 inches.

To Find :

The length possibilities (in whole inches) for the third side.

Solution :

We know, the sum of two sides of any triangle is always greater than the length of the third side.

Let, third side is d.

So, d is always less than the sum of other sides i.e. ( 24 + 36 ) = 60 .

d < 60

Also, difference between the difference of length is always less than the side.

So, d > 36 - 24

d > 12

Therefore, the length possibilities for the third side is between 13 inches and 59 inches.

Answer:

Number of game lose = 29 games (Approx)

Step-by-step explanation:

Given:

Winning part = 5/12

Total game = 49

Find:

Number of game lose

Computation:

Lose part = 1 - 5/12

Lose part = 7/12

Number of game lose = Total game x Lose part

Number of game lose = 49 x [7/12]

Number of game lose = 28.58

Number of game lose = 29 games (Approx)

They would lose 29 games if they play 49 games

They won 5 out of their first 12 games.

Hence the number of game lost in their first 12 games = 12 - 5 = 7  games

The rate at which they lose = 7 games / 12 games

Given that they played 49 games, hence:

Number of games lost = (7 games / 12 games) * 49 = 28.58

They would lose 29 games if they play 49 games
