what is the domain of the function f(x)=x^2+3+5?

Answer:

37 degrees.

Step-by-step explanation:

No matter how much smaller or bigger the shape is, it is still similar to the other shape, meaning they will have different angle measurements, but the degrees will remain the same.

Since Angle A is equal to Angle X. the measure of angle X will be 53 degrees.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

The triangles ABC and XYZ are similar.

Side AB is proportional to side XY

Side AC is proportional to side XZ

Since we know side AB and side XY are proportional to each other, sp there angles must be similar.

Angle A = Angle X

We know that in triangle ABC

Angle A + Angle B + Angle C = 180

Angle A + 90 + 37 = 180

Angle A = 53 degrees

Thus, Since Angle A is equal to Angle X. the measure of angle X will be 53 degrees.

Explanation:

W = (-2,3) is given

Point W ' is the result of reflecting point W over the x axis. We flip the sign of the y coordinate while keeping the x coordinate the same. So W ' = (-2, -3) as shown in the diagram below. The rule for reflecting over the x axis is [tex](x,y) \to (x,-y)[/tex]

Then reflecting over the y axis will have W ' = (-2, -3) become W '' = (2, -3). We flipped the x coordinate's sign this time. The rule for reflecting over the y axis is [tex](x,y) \to (-x,y)[/tex]

Going from W = (-2, 3) to W '' = (2, -3) is the rule [tex](x,y) \to (-x,-y)[/tex] which exactly describes a 180 degree rotation (either clockwise or counterclockwise).

This is one example showing how a composition of reflections results in a rotation. Note that you must have an even number of reflections to produce a rotation. One reflection reverses the orientation, so another reflection is needed to revert back to the original orientation (otherwise, a rotation is not possible as a rotation preserves orientation).

Answer:

(2, -3 )

Step-by-step explanation:

Where the y axis is left side we are asked to reflect -2 3 across into the 3rd quadrant. Then reflect across the y axis line into quadrant 4.

We see that x coordinate will stay -2,  but change from -2, 3  to -2, -3 into quadrant 3 and then stay -3 but change to 2 , -3 into quadrant 4.

We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:

[tex]\dfrac{1}{2} \times \dfrac{\sqrt{98}}{7}[/tex]

We can rewrite 98 into [tex]2 \times 49[/tex]

Answer:

14 seats in row 1.

Step-by-step explanation:

We must calculate how many seats there are for row 1, for that we are going to see the behavior that it takes from row 10 to 8, like this:

row 10 there are 41 and in row 9 there are 38, the difference would be:

41 - 38 = 3

now in row 9 there are 38 and in row 8 there are 35, therefore the difference would be:

38 - 35 = 3

Therefore, we can assume that each row less, there are 3 seats less, therefore:

41 - (10-r) * 3

where r would be the row, therefore if it is row 1 it would be:

41 - (10-1) * 3 = 14

Therefore there are 14 seats in row 1.

Answer:

There are 9 llamas.

Step-by-step explanation:

For Billy, we have to find a number that is divisible by four, because he has one group of lambs, and 3 times as many llamas, which gives us 4 groups altogether. The number must be below 10 in order to not go above 17 when Milly's number of animals are included, but above 4 itself in order to reach the target of 17 in the first place.

As you can guess, the only number that fits all the criteria is 8. It's divisible by 4 and below 10, but above 4 itself.

If Billy has three times as many llamas as lambs, then he must have 2 lambs, and 6 llamas, as 2 × 3 = 6.

If we know that Billy has 8 animals, then we also know that Milly must have 9 animals, as 17 - 8 = 9.

We also know that Milly has 3 groups of animals; one group of llamas, and two groups of lambs, meaning we divide the number of animals she has by 3.

9 ÷ 3 = 3.

This tells us Milly has just 3 llamas, because 3 is one group of 9, and 3 × 2 = 6,  because she has twice the amount of lambs.

Billy has 2 lambs and 6 llamas.

Milly has 6 lambs and 3 llamas.

The amount of lambs is irrelevant to our final answer, so we can disregard them and do a final sum of 6 + 3 = 9, which gives us our answer.

Answer:

Billy: Has 4 lots of animals

Milly: Has 3 lots of animals

17 animals in total means that Billy must have 4 lots of 2 (8 animals) and Milly must have 3 lots of 3 (9 animals) So Billy has 6 llamas and Milly has 3, giving 9 llamas in total

Answer:

y = x + 16

Step-by-step explanation:

Step 1: Find slope of perpendicular line

Take the negative reciprocal of the 1st line

m = 1

Step 2: Find b

y = x + b

14 = -2 + b

b = 16

Step 3: Write equation

y = x + 16

Answer:

y = x + 16

Step-by-step explanation:

Given the equation y = -x - 1, we see that the slope (the coefficient of the x term) is -1.  A line perpendicular to this one has a slope which is the negative reciprocal of the given equation:   +1.

Using the point-slope formula for the equation of a straight line, we get:

y - 14 = +1(x + 2), or y - 14 = x + 2, or y = x + 16

The given triangle is a right angle triangle.

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In the given triangle,

[tex]\tan (30^{\circ})=\dfrac{n}{\sqrt{3}}[/tex]

[tex]\dfrac{1}{\sqrt{3}}=\dfrac{n}{\sqrt{3}}[/tex]

[tex]1=n[/tex]

Using Pythagoras theorem, we get

[tex]m^2=n^2+(\sqrt{3})^2[/tex]

[tex]m^2=1^2+3[/tex]

[tex]m^2=4[/tex]

Taking square root on both sides, we get

[tex]m=\sqrt{4}[/tex]

[tex]m=2[/tex]

Answer: Rita has $25 saved.

Step-by-step explanation:

You could think about it this way: $69 is $6 less than 3 times the amount of money that she has. So, let's solve this:

1) First you would add $6 to the $69 that the skateboard costs because you     need to know what her savings would be if she multiplied it by 3.

      $69+$6=$75  

2) Now that we know that if we tripled her savings, we would have $75. We can now find out how much she actually has saved up by dividing the total of $75 by 3.

      $75÷3=$25

I hope this helped you with your question!

The found values are:

A = 1/3

B = -8/3

Step-by-step explanation:

We know that general equation is given by:

y = mx + c

where m is the slope and c is a constant.

x + 3y = -5

y = -(1/3)x - 1/3(5)

Slop of the equation is -(1/3). As parallel line have same slope substitute it in the first equation:

Ax + By = 3

By = -Ax - 3

By = (1/3)x - 3

Hence, A = 1/3

Substitute point (-7,2) into the equation:

B(2) = (1/3)(-7) -3

B(2) = -7/3 - 3

B(2) = -16/3

B = -16/6

B = -8/3

Answer:

a) z = 70.5°

b) s = 83.6°

c) x = 0.7cm

Step-by-step explanation:

We would solve for the above questions using Trigonometric functions of either Sine, Cosine or Tangent.

a) We are given the following values

Hypotenuse = 21 inches

The triangle is divided into two to give us a right angle triangle

The adjacent side = 14inches/2 = 7 inches

We are to find Angle z

The Trigonometric function we are using is Cosine

cos z = Adjacent / Hypotenuse

cos z = 7/21

cos z = 1/3

z = arc cos(1/3)

z = 70.528779366°

To 1 decimal place

z = 70.5°

b) We are given the following values

Hypotenuse = 12 cm

The triangle is divided into two to give us a right angle triangle

The opposite side = 16cm/2 = 8 cm

We are to find Angle s, but it is split into 2

So we represent the half as x

The Trigonometric function we are using is Sine

sin x = Opposite/ Hypotenuse

sin x = 8/12

sin x = 2/3

x = arc sin(2/3)

x = 41.810314896°

Remember in the question, we are to find s.

s = x° × 2

s = 41.810314896 × 2

s = 83.620629792

To 1 decimal place

s = 83.6°

c) From the above diagram, we are to find the Opposite side represented by x

Our triangle is split into two equal halves

Adjacent side = 2cm

Angle θ = 36°/2 = 18°

We are using Trigonometric function tan to solve for question c

tan θ = Opposite/ Adjacent

tan 18° = Opposite/ 2

Cross Multiply = tan 18° × 2

0.3249196962 × 2

= 0.726542528cm

To one decimal place,

x = 0.7cm

Answer:

a) Median = 91

b) mode = 91

c)Mean 84.2

Step-by-step explanation:

a) Median is the middle term. So, 6th term

Median = 91

b) Mode is the score which occurs more number of times

91 occurs 3 times

Mode = 91

c) Mean= sum of all data's/Number of data's

            = 85 + 91 + 48 +98 + 99 /5

            = 421/5

  Mean = 84.2

Answer:

72 cm^2

Step-by-step explanation:

If the Length is twice the Width, then W = W and L = 2W.

The perimeter formula is P = 2W + 2L, which here is:

                                      36    = 2W + 2(2W), or

                                        36 = 2W + 4W = 6W; then W = 6 and L = 12.

The area formula is A = L * W, which here is:

A = 6*12 = 72 cm^2
