Answer:

That is known as a Vertex

A figure formed by two rays that share a common endpoint is known as an angle. The common endpoint is known as the vertex, while the rays are considered the sides of the angle.

In mathematics, a figure formed by two rays that share a common endpoint is known as an angle. The common endpoint is referred to as the vertex and the rays are referred to as the sides of the angle.

Rays in the context of angles means a straight line that starts from a point (vertex) and extends indefinitely in a particular direction. For example, in a page of a book when it is half open, the two visible pages represent the rays, and where the pages meet (the spine) represents the vertex.

Answer:

  7 +1.25m = 43.25

Step-by-step explanation:

Let m represent the number of minutes on the trampoline. Then the charge (in dollars) for minutes you're on it is 1.25m. The entrance fee is added to that to give the total charges:

  7 + 1.25m = 43.25

Answer:

  c)  (-2, 6)

Step-by-step explanation:

Subtracting the second equation from the first gives ...

  (y) -(y) = (x^2 +3x +8) -(2x +10)

  0 = x^2 +x -2 . . . . . simplify

  0 = (x -1)(x +2) . . . . factor

Solutions for x are 1 and -2. The corresponding y-values are ...

  y = 2{1, -2} +10 = {2, -4} +10 = {12, 6}

The solutions are (1, 12) and (-2, 6). The only matching choice is (-2, 6).

hihi! so the ratio 2:1:3 can be rewritten as 2/6 (red) 1/6 (blue) and 3/6 (yellow).

this is because you have 2 floz of red, 1 floz of blue, and 3 floz of yellow, which adds up to 6 floz of paint total in your ratio.

since you have 18 fl. oz. of paint, you multiply the ratio 3/6 by 18 to get 9 fl. oz. of yellow paint.

hope this helps!

There would be of 9 ounces yellow paint needed.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

If tangents are drawn from the same spot, then they will be equal.

Since tangents AB and AC both start from point A, and go to the same circle, then:

AC = AB.

That means the statement:

'If AC is equal to 10cm, then segment AB is equal to 20cm'

is false

(if a AC  = 10cm, then AB would =  20cm as well)

_____________________________________

Answer:

False

Answer:

The given statement is false.

Step-by-step explanation:

We have been given a statement. We are supposed to determine whether our given statement is true or not.

Segments AC and AB are tangent to circle E. If AC is equal to 10 cm, then segment AB is equal to 20 cm.

We know that tangents of circle from same external point are congruent.

We can see that both tangents AB and AC are drawn from same point A, so AB will be equal to AC.

Since [tex]AB=20[/tex] and [tex]AC=10[/tex], therefore, our given statement is false.

For angles other than 1st-quadrant angles, it can sometimes be difficult to identify the relevant sides of the relevant triangle. If the angle were a 1st-quadrant angle, it would be clear that the side opposite the angle is the y-coordinate of the point on the terminal side. That remains the case for all angles. The hypotenuse is always the positive distance from the origin to the terminal point.

the smallest value of possible to obtain a k-coloring.

Final answer:

The chromatic number for a map is the minimum number of colors needed to color the regions of the map such that no two adjacent regions have the same color.

Explanation:

The chromatic number for a map is the minimum number of colors needed to color the regions of the map such that no two adjacent regions have the same color.

The chromatic number can vary depending on the specific map and its regions. To determine the chromatic number, one approach is to use a graph-theoretic representation of the map, where each region corresponds to a vertex and adjacent regions are connected by edges. Then, a graph coloring algorithm can be used to find the minimum number of colors needed to properly color the regions of the map.

Answer:

[tex]tan(\theta)=-\frac{7}{6}[/tex]

[tex]sec(\theta)=\frac{\sqrt{85} }{6}[/tex]

[tex]cos(\theta)=\frac{6\sqrt{85} }{85}[/tex]

[tex]sin(\theta)=-\frac{7\sqrt{85}}{85}[/tex]

[tex]cosec(\theta)=-\frac{\sqrt{85}}{7}[/tex]

Step-by-step explanation:

[tex]cot (\theta) = -\frac{6}{7}[/tex]

a) Since,

[tex]tan(\theta) = \frac{1}{cot(\theta)}[/tex]

[tex]tan(\theta) = \frac{1}{-\frac{6}{7} }=-\frac{7}{6}[/tex]

b) Also, according to the Pythagorean identity:

[tex]sec^{2}(\theta)=1+tan^{2}(\theta)[/tex]

Using the value of tan([tex]\theta[/tex]), we get:

[tex]sec^{2}(\theta)=1+(-\frac{7}{6} )^{2}\\\\ sec^{2}(\theta)=\frac{85}{36}\\\\ sec(\theta)=\pm \sqrt{\frac{85}{36} } \\\\ sec(\theta)=\pm \frac{\sqrt{85} }{6}[/tex]

Since, secant is positive in 4th quadrant, we will only consider the positive value. i.e.

[tex]sec(\theta)=\frac{\sqrt{85} }{6}[/tex]

c) Since,

[tex]cos(\theta)=\frac{1}{sec(\theta)}[/tex]

Using the value of secant, we get:

[tex]cos(\theta)=\frac{1}{\frac{\sqrt{85} }{6} } =\frac{6\sqrt{85} }{85}[/tex]

d) According to Pythagorean identity:

[tex]sin^{2}(\theta)=1-cos^{2}(\theta)\\sin(\theta)=\pm \sqrt{1-cos^{2}(\theta)}[/tex]

Since, sine is negative in fourth quadrant, we will consider the negative value. Using the value of cosine, we get:

[tex]sin(\theta)=-\sqrt{1-(\frac{6\sqrt{85} }{85})^{2}}=-\frac{7\sqrt{85}}{85}[/tex]

e) Since,

[tex]cosec(\theta)=\frac{1}{sin(\theta)}[/tex]

Using the value of sine, we get:

[tex]cosec(\theta)=\frac{1}{-\frac{7\sqrt{85} }{85}}=-\frac{\sqrt{85}}{7}[/tex]

Answer:

<1 = 100

<2 = 80

Step-by-step explanation:

Angle 1 and angle 2 are supplementary

Supplementary angles add to 180 degrees

<1 + <2 = 180

The angles are in a ratio of 5 to 4

Multiply by x to get the measure of each angle

<1 = 5x  <2 = 4x

5x+4x = 180

Combine like terms

9x = 180

Divide by 9

9x/9 =180/9

x =20

<1 = 5x = 5*20 = 100

<2 = 4x = 4*20 = 80

Choice A) [tex]F(x) = 3\sqrt{x + 1}[/tex].

Step-by-step explanation:

What are the changes that would bring [tex]G(x)[/tex] to [tex]F(x)[/tex]?

[tex]G(x) = \sqrt{x}[/tex]. The choices of [tex]F(x)[/tex] listed here are related to [tex]G(x)[/tex]:

The expression in the braces (for example [tex]x[/tex] as in [tex]G(x)[/tex]) is the independent variable.

To shift a function on a cartesian plane to the left by [tex]a[/tex] units, add [tex]a[/tex] to its independent variable. Think about how [tex](x-a)[/tex], which is to the left of [tex]x[/tex], will yield the same function value.

Conversely, to shift a function on a cartesian plane to the right by [tex]a[/tex] units, subtract [tex]a[/tex] from its independent variable.

For example, [tex]G(x+1)[/tex] is [tex]1[/tex] unit to the left of [tex]G(x)[/tex]. Conversely, [tex]G(x-1)[/tex] is [tex]1[/tex] unit to the right of [tex]G(x)[/tex]. The new function is to the left of [tex]G(x)[/tex]. Meaning that [tex]F(x)[/tex] should should add [tex]1[/tex] to (rather than subtract [tex]1[/tex] from) the independent variable of [tex]G(x)[/tex]. That rules out choice B) and D).

The graph of [tex]G(x)[/tex] is stretched vertically. However, similarly to the graph of this graph [tex]G(x)[/tex], the graph of [tex]F(x)[/tex] increases as [tex]x[/tex] increases. In other words, the graph of [tex]G(x)[/tex] isn't flipped about the [tex]x[/tex]-axis. [tex]G(x)[/tex] should have been multiplied by a number that is greater than one. That rules out choice C) and D).

Overall, only choice A) meets the requirements.

Since the plot in the question also came with a couple of gridlines, see if the points [tex](x, y)[/tex]'s that are on the graph of [tex]F(x)[/tex] fit into the expression [tex]y = F(x) = 3\sqrt{x - 1}[/tex].

Answer:

f(x) =3 sqrt(x+1)

Step-by-step explanation:

We notice two things about the graph, it has a shift to the left and is steeper

First the shift to the left

f(x) = g(x + C)  

C > 0 moves it left

C < 0 moves it right

g(x) is 0 at x=0   f(x) is 0 at  x=-1

We are moving it 1 unit to the left

This means our "c" is 1

f(x) = sqrt( x+1)

Now we need to deal with the graph getting steeper

f(x) = Cg(x)  

C > 1 stretches it in the y-direction

0 < C < 1 compresses it

Since it is getting taller, "c" must be greater than 1

Remember the - sign means it is a reflection across the x axis, which we do not have

f(x) =3 sqrt(x+1)

Answer:

They can buy 13meals if they buy 100 gallons of gasoline.

Step-by-step explanation:

3.50 PER gallon so 1 gallon is $3.50

if they buy 100 gallons you have to multiply 3.50 by 100 which gives you 350. you subtract 350 from 1000 so 1000-350 and get 650. now, you divide 650 by 50 because each meal is $50. And you get 13 so there you have it.

Final answer:

The family can buy 13 meals.

Explanation:

To find the number of meals the family can buy, we need to calculate the total cost of gasoline and subtract it from the total budget.

The family buys 100 gallons of gasoline at a cost of $3.50 per gallon, so the total cost of gasoline is 100 * $3.50 = $350.

The remaining budget for meals is $1,000 - $350 = $650.

The cost of each meal is $50, so the family can buy $650 / $50 = 13 meals.

The given confidence interval : (0.21, 2.45)              -------------(2)

From (1) and (2), we  have

[tex]\mu-E=0.21-------(3)\\\\\mu+E=2.45--------(4)[/tex]

Subtract equation (3) from (4), we get

[tex]2E=2.45-0.21\\\\\Rightarrow\ 2E=2.24\\\\\Rightarrow\ E=\dfrac{2.24}{2}=1.12[/tex]

Hence, the margin of error is 1.12 .

The margin of error can be calculated as half the width of the confidence interval.

The margin of error can be calculated by finding half the width of the confidence interval. In this case, the confidence interval is (0.21, 2.45), so the width is 2.45 - 0.21 = 2.24. Therefore, the margin of error is half of this width, which is 2.24/2 =

Step-by-step explanation:

By the Supplementary Angles Theorem, you add m<x by 165, and set that equal to 180°, or π. Of course you have to do the inverse of addition in order to get this, so deduct 165 from 180 to end up with 15.

The dimensions that minimize the total cost of material for the shipping crate are:

- Length: 24 feet

- Width: 24 feet

- Height: 8 feet

To solve this problem, we can start by writing down the volume formula for a rectangular box with a square base:

Volume = Length × Width × Height

Given that the volume is 3072 ft³, we have:

3072 = L × W × H

We also know that the material for the top and sides costs $4 per square foot and the material for the bottom costs $2 per square foot. Let's denote the areas of the top, bottom, and sides as A_top, A_bottom, and A_sides, respectively.

A_top = L × W

A_bottom = L × W

A_sides = 2 × (L × H + W × H)

The total cost, C, can be expressed as:

C = 4 × (A_top + A_bottom) + 2 × A_sides

C = 4 × (L × W + L × W) + 2 × 2 × (L × H + W × H)

C = 8LW + 4LH + 4WH

We can substitute the volume equation into the cost equation to eliminate one variable. Let's express L in terms of W and H from the volume equation:

L = 3072 ÷ (W × H)

Now substitute L into the cost equation:

C = 8(3072 ÷ (WH))W + 4(3072 ÷ (WH))H + 4WH

C = 24576 ÷ H + 12288 ÷ W + 4WH

To minimize C, we take the derivative with respect to W and H, set them equal to zero, and solve for W and H:

∂C/∂W = -12288/W² + 4H = 0

∂C/∂H = -24576/H² + 4W = 0

Solving these equations gives us W = 24 and H = 8, which leads to L = 3072 ÷ (24 × 8) = 16.

So, the dimensions that minimize the total cost of material are Length: 24 feet, Width: 24 feet, and Height: 8 feet.

Complete Question:
A shipping company must design a closed rectangular shipping crate with a square base. The volume is 3072ft3.

Answer:

(7, 0); the time it takes to empty the water in the pool

Step-by-step explanation:

The following table shows the amount of water leaking from an inflatable pool as a function of time:

x (time in minutes)    f(x)

0                            35

1                            30

2                            25

3                            20

4                             15

f(x) represents the amount of water in the pool. x intercept is the point where f(x) is 0 .At x intercept the amount of water in the pool is 0.

WE need to find out the point where f(x) becomes 0

F(x) is decreasing by 5. LEts extend the table till we get f(x) becomes 0

Decrease f(x) by 5

x (time in minutes)    f(x)

3                            20

4                             15

5                                  15-5=10

6                                  10-5=5

7                                   5-5=0

When x=7, f(x)=0. (7,0) is the x intercept.

(7, 0); the time it takes to empty the water in the pool
