The output value of y when input value x is -7:   -6

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check given expression is a function or not we can check it by a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

The length of f to the nearest 10th of an inch is 308.8 inches.

A trigonometric rule known as the Law of Sines connects any triangle's sides and angles. It claims that for all three sides of a triangle, the ratio of the length of one side to the sine of the angle opposite that side is the same. To put it another way, we may write: If we have a triangle with sides a, b, and c, and opposing angles A, B, and C:

Sin(A) / a = b / a sin(B) / c / sin (C)

Using the Law of Sines we have:

f / sin(89°) = e / sin(27°)

f = sin(89°) * 310 / sin(27°)

f ≈ 308.8 inches

Hence, the length of f to the nearest 10th of an inch is 308.8 inches.

Answer:

  613.7 in

Step-by-step explanation:

You want the length of side f in ∆EFG with e = 310 in, E = 27°, G = 89°.

The law of sines tells you ...

  f/sin(F) = e/sin(E)

Angle F is the third angle in the triangle, so its measure is ...

  F = 180° - 89° -27° = 64°

Then the length of f is ...

  f = e·sin(F)/sin(E) = (310 in)·sin(64°)/sin(27°) ≈ 613.7 in

The length of f is about 613.7 inches.

The equation for option 1 is y = 3.5x + 7.5 and option 2 is y = 5.5x. Option 1 will be the least expensive. The solution has been obtained by using the slope-intercept form.

What is slope-intercept form?

The graph of the equation y = mx + b is represented by a line with a slope of m and a y-intercept of b. The slope-intercept representation of the linear equation is employed, and the values of m and b are real numbers.

We are given two options.

Using slope-intercept form, we get the equations as

Option 1

It requires monthly fee of $7.50 which means this is the y-intercept and $3.50 per game which means this is the slope.

So, the equation is y = 3.5x + 7.5

Option 2

Slope = (33 - 16.5)/ (6 - 3)

Slope = 16.5/ 3

Slope = 5.5

The y-intercept for this is 0.

So, we get the equation as y = 5.5x.

Fee for renting 5 games

As per option 1: y = 3.5(5) + 7.5 = $25

As per option 2: y = 5.5(5) = $27.5

If she shoots 40 times and misses 8, we can create a ratio to represent the number of total shots to the number of misses:

40/8 = 60/x X represents the amount she will miss if she takes 60 shots.

We can find the value of x by using cross multiplication:

480 = 40x. We can now isolate x by dividing both sides by 40:

X = 12.

The value of x from the given triangle is approximately 19.10.

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

We can use the Pythagorean theorem to find the value of x. The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be represented as follows:

c² = a²+ b²

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

In this problem, c = 25, and we need to find the value of x which is the length of one of the other two sides. Let's call the other side y. Then, we can write the equation as follows:

25² = x² + y²

We are also given that the angle between x and y is 41 degrees. We can use trigonometry to find the value of y. The sine function gives us the ratio of the opposite side to the hypotenuse, so we can write:

sin(41) = y/25

Therefore, y = 25 * sin(41). Now that we have the values of x and y, we can substitute them in the equation derived from the Pythagorean theorem:

25² = x² + (25 * sin(41))²

Solving for x, we get:

x = √(25²- (25 * sin(41))²)

Using a calculator, we get that sin(41) = 0.661437827766148.

Now, we can substitute this value in the equation:

x = √(25² - (25 * sin(41))²)

x = √(25² - (25 * 0.661437827766148)²)

x = √(25² - (16.0359050108801)²)

x = √(625 - 256.132749101278)

x = √(368.867250898722)

x = 19.10

Hence, The value of x is approximately 19.10

Vertical compression factor: 1

Axis of reflection: -x + 6

Domain: all real numbers

The vertical stretch factor is a term used in mathematics to describe the transformation that changes the height of a graph while leaving the horizontal axis unchanged. In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.

The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward. If k > 1, the graph is stretched vertically; if 0 < k < 1, the graph is compressed vertically; if k = 1, the graph remains unchanged.

The equation to represent the function is y = 6x + 10 where y is the height of the drone in meters and x is the time in seconds. so the drone rises 6 meters per second.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Let us  find the rate of change, we can divide the total change in the height of the drone by the time taken for the change.

rate of change = (change in height) / (time taken)

(40 m - 10 m/ (5 s - 0 s)= 30 m/5 s=6m/s

The drone rises 18 m every 3 s

rise per second = 18 m / 3 s = 6 m/s

This means that the initial height of the drone is 10 meters, since it takes 3 seconds for the drone to rise to a height of 28 meters

The proof that z lies on the x-axis is shown below

For z to lie on the x-axis, then the coordinate must be represented as (x, 0)

Given that

[tex]\frac{|z - 5i|}{|z + 5i|} = 1[/tex]

We start by simplifying the given expression using the definition of the modulus of a complex number:

So, we have

[tex]\frac{|z - 5i|}{|z + 5i|} = \frac{\sqrt{(x - 0)^2 + (y - 5)^2}}{\sqrt{(x - 0)^2 + (y + 5)^2}} = 1[/tex]

Where

z = x + yi or z = (x, y)

Squaring both sides of the equation above, we obtain:

[tex]\frac{(x - 0)^2 + (y - 5)^2}{(x - 0)^2 + (y + 5)^2} = 1[/tex]

This gives

[tex]\frac{x^2 + (y - 5)^2}{x^2 + (y + 5)^2} = 1[/tex]

By comparison, we have

[tex](y + 5)^2 = (y - 5)^2[/tex]

Set y = 0 to test the equation

So, we have

[tex](0 + 5)^2 = (0 - 5)^2[/tex]

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the first term of the AP be a₁ = 1 3/4

Let the second term of the AP be a₂ = 1 9/16

So , the common difference of AP d = a₂ - a₁

On simplifying the equation , we get

The common difference d = 1 9/16 - 1 3/4 = ( 25/16 - 7/4 )

The common difference d = - ( 3/16 )

And , the nth term of the AP is a + (n - 1) d

So , the 5th term of the AP = ( 1 3/4 ) + ( 4 ) ( -3/16 )

On simplifying the equation , we get

The 5th term of the AP = ( 7/4 ) + ( -3/4 )

The 5th term of the AP = 4/4 = 1

Therefore , the value of A = 1

And , the 6th term of the AP = ( 1 3/4 ) + ( 5 ) ( -3/16 )

On simplifying the equation , we get

The 6th term of the AP = ( 7/4 ) + ( -15/16 )

The 6th term of the AP = 13/16

Therefore , the value of B = 13/16

And , the 7th term of the AP = ( 1 3/4 ) + ( 6 ) ( -3/16 )

On simplifying the equation , we get

The 7th term of the AP = ( 7/4 ) + ( -18/16 )

The 7th term of the AP = 10/16

Therefore , the value of C = 10/16
