Graph the inverse of the provided graph on the accompanying set of axes. You must
plot at least 5 points.

Answers

Answer:

*See attached image for the 5 points on the graph*

Step-by-step explanation:

Step 1: Find 5 points to calculate inverse

We can use the vertex(-1,-4), 2 y-intercepts(0,-3) and (0,-5) and 2 more points (3,-2) and (3,-6)

Step 2: Find the inverse

You find the inverse when you swap the 'x' and 'y' so it would be

Vertex: (-4,-1)

y-intercept 1:(-3,0)

y-intercept 2:(-5,0)

Point 1: (-2,3)

Point 2: (-6,3)

Step 3: Graph

Graph the points on a graph and connect the points

The inverse of a graph is done by reflecting the graph across the line [tex]y = x[/tex].

See attachment for the inverse graph.

From the given graph, we have the following 5 points.

[tex](x_1,y_1) = (8,-1)[/tex]

[tex](x_2,y_2) = (3,-2)[/tex]

[tex](x_3,y_3) = (-1,-4)[/tex]

[tex](x_4,y_4) = (3,-6)[/tex]

[tex](x_5,y_5) = (8,-7)[/tex]

Reflect the above points across [tex]y = x[/tex], to get the inverse function

[tex](x_1,y_1) = (-1,8)[/tex]

[tex](x_2,y_2) = (-2,3)[/tex]

[tex](x_3,y_3) = (-4,-1)[/tex]

[tex](x_4,y_4) = (-6,3)[/tex]

[tex](x_5,y_5) = (-7,8)[/tex]

The inverse graph must pass through the above points

Answer: C. 324 cm∧3

Just took quiz.

Based on the calculations, the volume of this pyramid is equal to: D. 324 cm³.

Given the following data:

Base area = 54√3 cm².Edge length = 6 centimeters.Angle BAC = 60°.

How to calculate the volume of a pyramid?

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

Next, we would find the height of this pyramid from the right-angled triangle ABC by applying Tan trigonometry formula:

Tanθ = Opp/Adj = BC/AC

Tan60 = height/6

√3 = height/6

Height = 6√3 cm.

Now, we can calculate the volume of this pyramid:

Volume = 1/3 × base area × height

Volume = 1/3 × 54√3 × 6√3

Volume = 1/3 × 972

Volume = 324 cm³.

Step-by-step explanation:

Looking at the universal set, there are 40 students at this high school, 15 of which play string, 20 play brass, and 5 play neither (probably drummers).  Note how there is no intersection of A and B, which is the probability we are looking for.

Since there is no intersection in the universal set between subset A and subset B, you can say that there is a probability of 0 since there is no overlap between the two subsets.

fives times a number and the difference of 6

Answers

Answer: The equation that has resulted from this is 5x - 6.

Step-by-step explanation:

So far, we know that the givens are:

fives times a number and the difference of 6

Then, we can conclude that the term "a number" means an unknown term, so all we have to do is put a variable in its place. It can be k, s, h, z, x, etc. Next, just find the difference of 6. So, from what we know, this is what our new equation looks like:

5 times ( a number) - the difference of 6

In math form:

5 (x) - 6

Then, add [tex]10x[/tex] to both sides:

[tex]58-10x+10x\leq20+9x+10x\\58\leq20+19x[/tex]

Next, subtract [tex]20[/tex] from both sides:

[tex]58-20\leq20-20+19x\\38\leq19x[/tex]

Finally, divide both sides by [tex]19[/tex]:

Step-by-step explanation:

Given AP with the first two terms:

a₁= 27 and a₂=24

Common difference:

d= 24-27 = -3

To find

n for which Sₙ= -30SolutionSₙ = 1/2*n*(a₁+aₙ) = 1/2n(a₁+a₁+(n-1)d) =1/2n(27+27+(n-1)(-3))= 1/2n(54 - 3n + 3) = 1/2n(57 - 3n)

Since Sₙ = -30

1/2n(57 - 3n) = -3057n - 3n² = -6019n - n²- 20 = 0n² -19 n -20= 0

Solving the quadratic equation we get:

Look at the triangle ABC. What is the length of the side AB of the triangle? A.) 3 B.) 5 C.) Square root of 6 D.) Square root of 13

Answers

Answer:

The answer is option D

Step-by-step explanation:

To find the length of AB we use the formula

[tex] \sqrt{ ({x _{1} - x_{2}})^{2} + ({y_{1} - y_{2} })^{2} } [/tex]

Where

(x1 , y1) and (x2 , y2) are the points

From the question

A is (4 , 5) B is (2 , 2)

So the length of AB is

[tex] |AB| = \sqrt{ ({4 - 2})^{2} + ({5 - 2})^{2} } [/tex]

[tex] |AB| = \sqrt{ {2}^{2} + {3}^{2} } [/tex]

[tex] |AB| = \sqrt{4 + 9} [/tex]

We have the final answer as

[tex] |AB| = \sqrt{13} [/tex]

Answer:

sqrt(13) = c

Step-by-step explanation:

The length of BC = 4-2 =2

The length of AC = 5-2 =3

We can use the Pythagorean theorem

2^2 + 3^2 = c^2

4+9 = c^2

13 =c^2

Take the square root of each side

sqrt(13) = c

On a map, 1/4 inch between locations represents an actual distance of 2 miles between the locations. What is the actual distance, in miles, between the two cities that are 3 3/4 inches apart on the map?

Answers

Answer:

30 miles

Step-by-step explanation:

1/4 = 2

3  3/4 = x

15/4 = x

So, Cross multiply

=> 1/4 * x = 15/4 * 2

=> 1/4x = 15/4 * 4/2

=> 1/4x = 60/8

=> 1/4x = 7.5

=> 1/4x * 4 = 7.5 * 4

=> x = 30

So, 15/4 inches on the map equals 30 miles.

Earl needs to fill juice cups for his little brother's birthday party. There are 25 juice cups and each juice cup holds 12 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Earl need to purchase? (2 points) (1 quart = 32 fluid ounces, 1 gallon = 4 quarts) 1 bottle 2 bottles 3 bottles 4 bottles

Answers

Answer:

3 bottles

Step-by-step explanation:

Hello!

First, we find out how many fluid ounces 25 cups of juice hold.

One cup holds 12 fluid ounces so to find 25 we do

25 * 12 = 300 fluid ounces

Next, we find out how many fluid ounces one gallon holds.

One gallon is 4 quarts.

1 quart is 32 fluid ounces so to find how many 4 holds we do

32 * 4 = 128

So one gallon holds 128 fluid ounces

To find how many we need we divide the total needed by how much one bottle holds

300/128 = 2.34

You can't buy exactly 2.34 bottles of juice so we round up to the nearest whole number we will just have extra leftover

The answer is 3 bottles

Answer:

[tex]\Huge \boxed{{x=56\°}}[/tex]

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Create an equation.

64 + x + 60 = 180

Solve for x.

Add the numbers.

x + 124 = 180

Subtract 124 from both sides.

x + 124 - 124 = 180 - 124

x = 56

Answer:

56°

Step-by-step explanation:

64 + 60 = 124180 - 124 = 56

Why?

We did 64 + 60 because they are the two degrees that is given to us, and those two added with x will give us 180.When we add 64 and 60 together, we get 124. We then subtract that total from the total of the three angles to give us the remaining angle., which is 56.

Therefore, x is 56°

Answer:

The correct option is;

A. Randomized block design

Step-by-step explanation:

A randomized block design is one where the sample or subjects of the experiment are split into groups called blocks of experimental units where the variation in each block is lower than the variation among or between blocks, such that variation is controlled. In a random order, the treatments are performed on each experimental of the blocks.

In the question, the experimental units are grouped by gender and the treatment (consumption of chocolate or placebo) is randomly administered to the experimental units.

The four angles in a quadrilateral are in the ratio 2:5:6:7. Find the smallest angle in the quadrilateral?

Answers

Answer:

36º

Step-by-step explanation:

Since all the angles are in a ratio, and all angles add up to 360º, we can set up a simple equation to find the smallest angle.

2x + 5x + 6x + 7x = 360

20x = 360

x = 18

18 is NOT the answer since the smallest angle has a ratio number of 2. So we multiply 18 with 2 to get 36º.

2:5:6:7

Multiply by x

2x:5x:6x:7x

Add them together to get 360

2x+5x+6x+7x = 360

20x = 360

Divide each side by 20

20x/20 = 360/20

x =18

The smallest angle is 2x

2*18 = 36
