What type of angle turns through 1 360 of a circle?.

The type of function always has an inverse is one to one.

In math function is referred as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Here we need to identify the type of the function always has an inverse.

As we all know that in each and every function has an inverse, here we have also know that but not every inverse will be a function.

Where as the inverse may fail the vertical line test.

Here we have identified that if the original function is a one-to-one function then its inverse will be a function.

Finally in a one-to-one function not only passes the vertical line test, then it also passes a horizontal line test.

32.56 is the expected weight for a bluegill fish that is 11 inches long.

Equation: What is it?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party. Multiple terms, operators, and variables are not required on each side of an equation. Without them, one can still create an equation, such as 5 + 10 = 15. There are no variables in the equation below.

given expression:

In(Weight) = -5.28 + 3.44 In(Length)

So, we have to find 11 inches then

In(weight) = -5.28 + 3.44 x 11

               = -5.28 + 37.84

               = 32.56

Hence, 32.56 is the expected weight for a bluegill fish that is 11 inches long.

According to the question A line has a slope of -3 and includes the points (9, 4) and (8, t) then the value of t is 7

Typically, a line's slope provides information about the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, (x1,y1) and (x2,y2). The letter "m" is typically used to signify slope.

tan θ = Δy/Δx

the solution is -

Considering a line with a slope of -3 and also the point (9, 4), we could use the point-slope form of either a line to find the equation of a line:

y - 4 = -3(x - 9)

y = -3x + 27 + 4

y = -3x + 31

We are given some other point on the line (8, t) we can try substituting it in the equation above:

t = -3(8) + 31

t = -24 + 31

t = 7

Consider given equation x₁ + x₂ + x₃ + x₄  = 17,

where x₁ , x₂ , x₃ and x₄ are non-negative integers.

As we know x₁ is the number of ones before the first zero, x₂ the number of ones between the first and the second zero, x₃ the number of ones between the second and the third zero, and x₄ is the number of ones after the third zero.

This means, there is a 1-1 correspondence between the solutions and reorderings of 17 ones and 3 zeros.

So, the number of solutions to given equation would be,

A. The work done is 300 ft-lbs when a 100 lb rock is lifted to a height of 3 ft.

To calculate the work done, we can use the formula: Work = force x distance x cos(Ф).In this case, the force is the force of gravity acting on the rock, which can be calculated using the formula:

force = m * g

where m is the mass of the rock and g is the acceleration due to gravity (32.17 ft/s^2).

force = 100 lb * 32.17 ft/s^2 = 3,217 ft-lbs

The distance is the height to which the rock is lifted, which is 3 ft.

The angle of the rock to the vertical is 90 degrees, so cos(90) = 0.

So,

Work = force x distance x cos(theta) = 3,217 ft-lbs * 3 ft * 0 = 300 ft-lbs

So, the work done is 300 ft-lbs.

Substitution is a method for solving systems of equations by substituting the values from one equation into the other. To use substitution to determine if an ordered pair is the solution to a system of equations, first solve one of the equations for either x or y.

Then substitute this value into the other equation, and solve for the other variable. If the ordered pair you obtain is also found in both equations, then it is a solution to the system.

Take the equation set as an example.

2x + y = 5

3x – y = 1

To use substitution to determine if (2, 3) is a solution to this system, first solve one of the equations for either x or y:

2x + y = 5  ⇒ y = 5 – 2x

Add this value to the other equation after that:

3x – (5 – 2x) = 1  

⇒  5x = 6  

⇒ x = 6/5

Finally, substitute 6/5 back into either equation to find y:

2(6/5) + y = 5  

⇒ 12/5 + y = 5  

⇒  y = 10/5  

⇒  y = 2

Since (6/5, 2) is found in both equations, it is a solution to the system.

There are several ways to find the measure of an angle in a triangle, depending on the information given about the triangle and the angles. Some common methods include:

Using the angles in a triangle sum to 180 degrees: If you know the measures of two angles in a triangle, you can use the fact that the angles in a triangle sum to 180 degrees to find the measure of the third angle.

Using the Pythagorean theorem: If you have a right triangle, you can use the Pythagorean theorem to find the measure of the right angle (90 degrees)

Using the Law of Cosines: If you know the measures of two angles and the lengths of all three sides of a triangle, you can use the law of cosines to find the measure of the third angle.

Using trigonometry: If you know the lengths of two sides of a triangle and the measure of one angle, you can use trigonometry to find the measure of the other angles.

It is important to note that in order to find the measure of an angle you need to know at least one angle and the values of the sides of the triangle or two angles.

Answer:

30 tiles

Step-by-step explanation:

We know

First store

$0.59 per tile

Rent a tile saw for $18

Second store

1 tile = $1.19

We have the equation

0.59x + 18 = 1.19x

18 = 0.6x

x = 30 tiles

So, she must buy 30 tiles for the same cost at both stores.

Answer:

Margo must purchase 30 tiles for the cost to be the same at both stores.

Step-by-step explanation:

By analyzing the "real-world" problem, we can convert the words into two algebraic equations.

Store 1:

"$0.59 per tile and rent a tile saw for $18."

y = 0.59x + 18

y = the price of the tiles bought

0.59 = price of one tile

x = number of tiles

18 = the fixed cost of a saw

Store 2:

"At another store, she can borrow the tile saw for free if she buys tiles there for $1.19 per tile."

In this case, the saw is free. Thus, we don't need to add a price to the equation.

y = 1.19x

y = the price of the tiles bought

1.19 = price of one tile

x = number of tiles

Now that we have both equations, we can write down the equations that equate other. This formula will indicate that the equations would intersect at a certain point on the x and y values. Hence, this step will answer how many tiles are required for both stores to equal the same price.

[tex]0.59x+18=1.19x[/tex]

Now solve for x:

[tex]0.59x-0.59x+18=1.19x-0.59x\\\\18=0.6x\\\\\frac{18}{0.6} =\frac{0.6x}{0.6}\\\\30=x[/tex]

Margo can buy 30 tiles from both stores for the cost to be equal.

You might ask, "But what about the price?" This is where we solve for y; this variable will answer how much the tiles would cost at 30 tiles. So, we can take the answer for "x" and plug it into any of the two equations.

[tex]y=1.19x\\y=1.19(30)[/tex]

For this equation, all you have to do is multiply both numbers to get your answer.

[tex]y=35.7[/tex]

Therefore, Margo can buy 30 tiles for the cost to be same at both stores at $35.70.

Answer:

x = -3

y = 5

Step-by-step explanation:

3x + 2y = 1

5x + 4y = 5 ​

First, we multiply the first equation by -2

-6x -4y = -2

5x + 4y = 5

-x = 3

x = -3

Now put -3 back in for x and solve for y

3(-3) + 2y = 1

-9 + 2y = 1

2y = 10

y = 5

Let's check

3(-3) + 2(5) = 1

-9 + 10 = 1

1 = 1

So,  x = -3 & y = 5 is the correct answer.
