g={(-9,6),(-6,4),(2,-6),(6,-5)}
h(x)=3x-4
find the following
g^-1(-6)=
h^-1(x)=
(h^-1·h)(3)=

Answers

Answer 1
a) The ordered pair with -6 as the dependent value is (2, -6).
  g^-1(-6) = 2


b) Swap x and y and solve for y.
  x = 3y -4
  x +4 = 3y
  (x +4)/3 = y
Then the inverse function can be written as
  h^-1(x) = (x +4)/3


c) You have shown the product of h^-1(x) and h(x). We have to assume that is what you intend.
  h^-1(3) = (3 +4)/3 = 7/3
  h(3) = 3×3 -4 = 5
  (h^-1·h)(3) = h^-1(3)·h(3) = (7/3)·5
  (h^-1·h)(3) = 35/3

If you intend (h^-1◦h)(3), that value is 3.

what is the answer to 5+2x10

Answers

We are given expression :  5+2x10.

It can be read as 5 plus 2 times 10.

Now, we need to see, what operation should carry out first.

Please note: We always follow the order of operations.

The order of operations could be follow by the rule  PEMDAS.

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

We don't have Parentheses, Exponents in the given problem.

So, we would start order of operations: first multiplication and then addition.

So, we need to multiply 2 × 10 first.

2 × 10 = 20.

Now, we need to apply addition operation.

Therefore, 5+2x10 = 5+20.

On adding 5 and 20, we get 25.

So, the final answer is 25.

Answer:

25 (assuming the x means multiplication)

Step-by-step explanation:

Start by using PEMDAS (Parenthesis, exponents, multiplication and division from right to left, addition and subtraction from right to left) you would start with multiplication or 2x10 which is 20 and then you have 5+20 left and that is obviously just 25

A circle has an area of 78.5 square inches. What is the diameter of the circle?

Answers

We have to know the formula to finding the area of a circle. Since the area is clearly rounded, we can use 3.14 for pi.
R^2•3.14=78.5
Let’s divide both sides by 3.14.
R^2=25
5•5
5
So the radius is 5. The diameter is double the radius. The diameter of the circle is 10.
Final answer:

To determine the diameter of a circle with an area of 78.5 square inches, we solve for the radius using the area formula (A = πr²). We find the radius to be 5 inches, and since the diameter is twice the radius, the diameter is 10 inches.

Explanation:

The student has asked how to determine the diameter of a circle if the area is known to be 78.5 square inches. To find the diameter, we first need to calculate the radius using the area formula for a circle, which is A = πr², or area equals pi times the radius squared. Pi (π) is approximately 3.14159, but for most calculations, we can use 3.14 for simplicity.

To solve for the radius, we rearrange the formula to r² = A / π. Plugging in the given area of 78.5 square inches:

r² = 78.5 / 3.14 = 25

Next, we take the square root of both sides to find the radius: r = √25 = 5 inches.

Now that we have the radius, we can determine the diameter by multiplying the radius by 2, as the diameter is twice the length of the radius. Thus, the diameter of the circle is 10 inches.

The base of a pryramid can be any polygon how many faces does a pentagonal pyramid have ? Describe the shapes of the faces 22 points plz help give a good answer

Answers

The pentagonal pyramid will have 6 faces: 5 triangular and 1 pentagonal.  We know what one face is - the pentagonal base.  Since a pentagon has five edges, and the other triangular faces extend from these edges to the point of the pyramid, there must be 5 other sides.  I have also attached images of this pyramid both regular and flattened out so you can picture what it looks like.

A pentagonal pyramid has six faces: one pentagonal base and five triangular lateral faces. Each side of the pentagonal base connects to the apex forming five triangular faces. The total number of faces is six.

A pyramid is a three-dimensional geometric shape with a polygon as its base and triangular faces that meet at a single point called the apex.

A pentagonal pyramid has a base in the shape of a pentagon.

The total number of faces in a pentagonal pyramid equals the number of sides on the base (5) plus one more for the base itself, giving a total of six faces.

Thus, a pentagonal pyramid consists of six faces - one pentagonal base and five triangular lateral faces.

20 cups of oats and the number of cups of raisins times 2

Final answer:

Rosa can play a total of 60 games with 120 tokens.

Explanation:

To determine the number of games Rosa can play with 120 tokens, we need to divide the total number of tokens by the number of tokens required to play a game. Since each game costs 2 tokens, we divide 120 by 2. This gives us the number of games Rosa can play, which is 60.



We can also write a rule to calculate the number of games Rosa can play. Let G represent the number of games, and T represent the number of tokens. The rule would be: G = T ÷ 2. We can substitute T with 120 to find G: G = 120 ÷ 2 = 60.

Answers

X will be ticket cost Y is ticket agency fee 5X+y = $93 3x+y = $57 To solve, multiply the second by negative 1. -3x-y = -$57 Then subtract the second from the first. 5X+y = $93 -3x-y = -$57 To give you 2x=$36 Divide both sides by 2 to get x=$18 If x=$18, then plug it in to get your solution for y! 5($18) +y =$93 $90+y=$93 Y=$3 3($18)+y = $57 $53 +y =$57 Y=$3


Final answer:

The question can be solved using a system of linear equations. The price of each ticket is found to be $20, and the fixed fee added by the ticket agency is $13.

Explanation:

The subject of this question concerns solving a system of linear equations. Given the two scenarios, buying 5 tickets for $93 and buying 3 tickets for $53, we can represent these as equations where 't' represents the price of a ticket and 'f' represents the fixed fee. The equations thus become:

5t + f = 933t + f = 53

To solve this system of equations, we could subtract the second equation from the first, which would eliminate 'f' and yield an equation only in terms of 't'. This would look like:

2t = 40

From here, we can see that t (the price of each ticket) equals $20. We can then substitute 't' into one of the equations to find the fixed fee 'f', which in this case equals $13.

A. Lily made $75.36 more than Layla.
B. She is incorrect.

A. First find out how many cupcakes each made. To do so, you multiply 8 by 60 to find how many minutes are in those 8 hours, then divide by the number of minutes it took for each batch.
Next you'd multiply the answer you get by the number of cupcakes in each batch, to get how many they made total.
After that, you find how many each of them sold.
Then, you multiply how many they sold, by how much each costed.
Finally, you subtract the smaller value from the larger value to find the difference, and who made the most money.

Lily: First, 8*60 = 480. Divide 480 by 10 (how long each batch took) to get 48. Multiply 48 by 7 to get how many cupcakes she made (336).
Next, divide 336 by 3, to get 112, then multiply by 2 to find how many she sold (2/3 of 336 = 224).
Then, multiply 224 by $1.29 to find how much she made ($288.96).

Layla: First, 8*60 = 480 and divide 480 by 12 (again, how long each batch took) to get 40.
Multiply 40 by 8 (cupcakes per batch) to get 320.
Divide 320 by 4 to get 80, then multiply 80 by 3 to get how many she sold (240).
Multiply $0.89 by 240 to get her total ($213.60).
Finally, subtract Layla's total from Lily's total to find out how much more Lily made.

B. Since Layla made 240 cupcakes, and she thinks selling each for a dollar will make her total larger than Lily's, multiply $1.00 by 240, to get $240.00, thus proving her hypothesis was incorrect.

17) what is the area of a regular hexagon with a perimeter of 240cm?

I have more questions but will post separately because they are all pictures!!!!

Answers

Answers:
(1) Base
(2) Sector of a circle
(3) Radius
(4) Adjacent arcs
(9) 30
(13) 256 ft^2
(17) 4156.92 cm^2

Explanations:
(1) It's a common convention that you can choose any side of a triangle as a base, but in specific cases like in the right-angled triangle, the base should always be the adjacent leg with which the 90 degree angle is made. In other words, in the case of right-angled triangle, the two legs of a triangle must be perpendicular to one another (meaning make 90 degrees angle). But in general triangles you can choose any side as a base of a triangle.

(2) The image is attached below. As you can see that a sector of a circle is actually the region which is shaded. Two radii that meet at the end points of an arc yield a region within a circle know as "sector". Hence the correct fill in the blank is the "sector of a circle." 

(3) The radius of a regular polygon is the distance from the center to any vertex. It is the same for each and every vertex. The radius is also the radius of the polygon's circumcircle, which is the circle that passes through every vertex. In this role, it is sometimes called the circumradius. Hence the correct answer is "radius."

(4) Adjacent arcs in simple words are the arc that lie next to each other. They have one point in common being next to each other. Hence the correct answer is adjacent arcs. One interesting fact is that a circle is made up of very large number of adjacent arcs.

(9) As the hypotenuse is mentioned, it means that it is a right-angled triangle; therefore:

Area of a right angled triangle = 1/2 * base * height
Area of a right angled triangle = 1/2 * 5* 12 = 30 ft^2

(13) The picture consists of FOUR right-angled triangles (making a parallelogram) therefore the area would be:
Area = 4 * 1/2 * base * height
Area = 4 * 1/2 * 12.8* 10 = 256 ft^2

(17) The general formula for the area of a polygon is:
Area = [tex] \frac{3 \sqrt{3} a^2 }{2} [/tex]

Where P = perimeter = 6a (hexagon)
=> a = P/6 

Plug in the values
Area = [tex]\frac{ \sqrt{3} P^2 }{24} = \frac{ \sqrt{3} (240)^2 }{24} = 4156.92 cm^2[/tex]

4 ft × 12 = 48 in
2 yds × 36 = 72 in

Multiply 48 × 22 × 72 = 76032.

The volume of the cage is 76,032 in³.

Step One
Convert all the non inch measurements to inches.

4 feet [ 12 inches / 1 foot] = 48 inches      [The feet as units cancel]
22 inches = 22 inches. No conversion needed.
2 yards [ 3 feet / yard ] * [ 12 inches / foot ]  = 72 inches.

Step Two
Find the volume

V = L * W * H
V = 48 * 22 * 72
V = 76032 cubic inches. <<<<<< Answer

The running back for the Bulldogs football team carried the ball 3 times for a total loss of 6 3/4 yards. Find the average change in field position on each run. Enter the average change as a simplified mixed number.

Answers

-6 3\4 / 3 = -2 1/4
Average of -2 1/4 yards per play
Final answer:

The average change in field position per run is -2 1/4 yards. This is found by dividing the total yardage lost (6 3/4 yards) by the number of runs (3).

Explanation:

The subject of this problem is calculating the average. In this case, we are looking for the average yardage lost by the running back on each run. The running back for the Bulldogs football team has carried the ball 3 times for a total loss of 6 3/4 yards.

To find the average change in field position on each run, divide the total loss by the number of runs:

Convert the mixed number 6 3/4 to an improper fraction. This gives us 27/4. Divide the numerator (27) by the denominator (4). This gives us -6.75. Divide -6.75 by 3 (the number of runs). This gives us -2.25. Convert -2.25 to a mixed number, which gives us -2 1/4.

Therefore, -2 1/4 yards is the average change in field position on each run.
