Which Of The Following Graphs Represents The Reflection Of The Point ( -3, 5) Over The X-axis? I Have

Answers

Answer 1

We have to identify the graph that represents the reflection of the point (-3,5) over the x-axis.

A reflection over the x-axis can be defined by the following rule: if we have a point (x,y), the image point after the reflection will have the same x-coordinate but the opposite of the y-coordinate.

It can be expressed as:

[tex]P=(x,y)\longrightarrow P^{\prime}=(x,-y)[/tex]

Then, the image point for (-3,5) will be:

[tex](-3,5)\longrightarrow(-3,-5)[/tex]

Then, this can be represented in a graph as:

This matches the following graph:

The domain can be best described using interval notation. The domain is [-7,8].

The range can be best described using interval notation. The range is [-4,3]

The graph of a function is given. As the graph is a straight line, it is clear that the function is a linear function. Also the function graphed has no breaks or jumps. Hence the function is continuous.

The domain of a function is the x-values for which the function is defined or the function has values.

The values of the function corresponding to the x-values in the domain is called the range. It is also called image and is a subset of the co-domain set.

Now since the graph of the function given is continuous we can better describe the domain and range of the function in the form of intervals.

The x-values for which the function is defined lies form -7 to 8 on the x-axis and hence it is the domain.

The y-values corresponding to the x-values in the domain lies between -4 and 3 on the y-axis and hence it is the range.

That is,  The domain is [-7,8] and  The range is [-4,3].

Lookout station A is 12 miles from the fire. Lookout station B is 39 miles from station A. The angle at station A is 52°. Find the distance between Station B and the fire.

Answers

Therefore, in order to find out the distance from station b to the fire, we must use the sine formula, as we know that sine is the opposite side divided by the hypotenuse.

We want to find out the opposite side and we already have the hypotenuse that is 12 miles.

A spherical tank for liquefied petroleum is 8.0 in. In diameter. What is the ratio of the surface area to the volume of tank

Answers

The ratio of the surface area to the volume of the tank is 3 : 4

What is volume?

The volume of a shape is the amount of space in it

How to determine the ratio?

The given parameter is

Diameter, d = 8.0 inches

Calculate the radius of the above diameter

So, we have

r = d/2

Substitute the known values in the above equation

r = 8/2

Evaluate

r = 4

The surface area of a sphere is

A = 4πr²

Where r represents radius

So, we have

A = 4π(4)²

The volume of a sphere is

V = 4/3πr³

Where r represents radius

So, we have

V = 4/3π(4)³

The ratio is represented as

Ratio = A : V

So, we have

Ratio = 4π(4)² : 4/3π(4)³

Divide by 4³π

Ratio = 1 : 4/3

Multiply the ratio by 3

Ratio = 3 : 4

Hence, the ratio is 3 : 4

A rectangular piece of cardboard that is 10 inches by 14 inches has squares of length x inches on a side cut from each corner. (Assume that 0 < x < 5.) If the flaps of the figure are folded up, an open box is formed. Represent the volume of this box in the form of a polynomial function V(x).

Answers

This is an aproximation of the described situation. We are taking 4 squares of side lenght x from each corner.

The dashed lines mark up what would be the base of the box. The blue scrabbled areas will be the sides of the box.

Recall that to calculate the volume of the box, we need to multiply the lenghts of each side of the base and then multiply it by the height of the box. So, to calculate the volume we need to determine the lenght of the dashed lined.

Let us calculate the lenght of the black dashed lines. Notice that the horizontal side has a total lenght of 14. So, since we are taking 2 squares of side x, we have that the lenght of the dashed line plus twice the lenght x, we get the total lenght of the side. That is

[tex]\text{Black dashed line + 2x = 14}[/tex]

Then the lenght of the black dashed line is 14-2x.

In the same manner, we can calculate the red dashed lines' lenght. It is 10-2x. Now, our box would be

In the picture, the green line represents the height. Comparing the blue and red lines, we have that the lenght of the green line corresponds to the lenght of the side of the square (x).

So now, we know that the volume of the box is

height * lenght of the base * width of the base = (14-2x)*(10-2x) * (x)

which is a polynomial of the variable x.

I need help solving: c= 8a-3b and solve for a

Answers

hello

[tex]c=8a-3b[/tex]

solve for a

step 1

add 3b to both sides of the equation

reason; we're doing this so that we take -3b to the other side of the equation so the we can have a and it's coefficient on one side of the equation

[tex]\begin{gathered} c=8a-3b \\ c+3b=8a-3b+3b \\ c+3b=8a \end{gathered}[/tex]

or we can simply say take -3b to the other side of the equation in order to make it easy to equate a

but note that whenever a variable or real number crosses an equality or inequality sign, the sign changes from either positve (+ve) to negative (-ve) or negative (-ve) to positive (+ve).

in this case, -3b

now we have our equation almost set

step 2

divide both sides by 8 to solve for a

Answers

Answer: 4

Step-by-step explanation:

To find the first term you replace n with 1.

a(1) = 3(1) -7

a(1) = -4

Now that you have the first term you must find the fifth term by filling in 5 for n.

a(5) = 3(5) - 7

a(5) = 15 - 7

a(5) = 8

Now that we have both terms simply add them together to find the sum.

Step 1: Let's review the information given to us to answer the problem correctly:

• p = Principal

,

• 0.12 = Interest rate

• 224 = Future value

Step 2: Let's write a problem based on this information, using the Simple Interest Formula, as follows:

A = P(1 + rt), where:

A = Final amount

P = Principal

r = Annual interest rate

t = Time in years

224 = P (1 + 0.12t)

The value of set A union set B is A ∪ B = { 1, 2, 3, 5, 6, 7 }.

Consider the set,

A = { 1, 2, 3 }

And, B = { x | x is an odd whole number less than 8 }

An integer's parity determines whether it is even or odd. If an integer is a multiple of two, it is even; otherwise, it is odd.

Therefore, all the numbers less than 8 are:

Therefore, the set B will be:

B = { 1, 3, 5, 7 }

In set theory, the set containing every element in a collection is the union of all its sets.

Answers

Answers to both subparts are given below:

(A) Yes, x = 6 is the solution of the equation 8x+8 = 56.(B) We need to add 24 on the right side of the equation when x = 9.

What do we mean by equations?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

So, (A) x = 6 is the solution of equation 8x+8 = 56:

Substitute x = 6 in equation 8x+8 = 56 as follows:

8x+8 = 568(6)+8 = 5648 + 8 = 5656 = 56

Yes, x = 6 is the solution of the equation 8x+8 = 56.

(B) The change on the right side if x = 9:

Substitute x = 9 in equation 8x+8 = 56 as follows:

8x+8 = 568(9) + 8 = 5672 + 8 = 5680 = 56

Now,

80 - 56 = 24

Explanation:

To find thh correct category, we need to calculate the amount spend on each category for each family, so taking into account the circle graphs, we get:

Family A (income: $5,400)

Housing: 5400 x 19% = 1026

Food: 5400 x 14% = 756

Childcare: 5400 x 18% = 972

Transportation: 5400 x 11% = 594

Insurance: 5400 x 23% = 1242

Other Needs: 5400 x 9% = 486

Taxes: 5400 x 5% = 270

Saving: 5400 x 1% = 54

Family B (income $4675)

Housing: 4675 x 16% = 748

Food: 4675 x 16% = 748

Childcare: 4675 x 18% = 841.5

Transportation: 4675 x 13% = 607.75

Insurance: 4675 x 28% = 1309

Other Needs: 4675 x 7% = 327.25

Taxes: 4675 x 2% = 93.5

Family C (income: $6675):

Housing: 6675 x 14% = 934.5

Food: 6675 x 11% = 734.25

Childcare: 6675 x 30% = 2002.5

Transportation: 6675 x 9% = 600.75

Insurance: 6675 x 20% = 1335

Other Needs: 6675 x 6% = 400.5

Taxes: 6675 x 10% = 667.5

Now, we need to calculate the differences in each categories:

Housing

A - B = 1026 - 748 = 278 > 25

Food

A - B = 756 - 748 = 8

B - C = 748 - 734.5 = 13.5

A - C = 756 - 734.25 = 21.75

Childcare

A - B = 972 - 841.5 = 130.5 > 25

Transportation

A - B = 594 - 607.75 = -13.75

B - C = 607.75 - 600.75 = 7

A - C = 594 - 600.75 = -6.75

Insurance

A - B = 1242 - 1309 = -67 < -25

Other Needs

A - B = 486 - 327.25 = 158.75 < 25

Taxes

A - B = 270 - 93.5 = 176.5 > 25
