Which function does not have a vertical asymptote

Answer:

C

Step-by-step explanation:

The sum of the angles is 90

2x + x = 90

3x = 90

x = 30

the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees

Given:

The function is:

[tex]y=x+2[/tex]

To find:

The inverse of the given function.

[tex]y=x+2[/tex]

Solution:

We have,

[tex]y=x+2[/tex]

Step 1: Interchange x and y.

[tex]x=y+2[/tex]

Step 2: Solve to y.

[tex]x-2=y[/tex]

[tex]y=x-2[/tex]

Therefore, the inverse of the given function is [tex]y=x-2[/tex].

According to the question the angle between right angle triangle hence the   M∠1 = [tex]90^{0}[/tex] .

90 degrees or a straight angle is always one angle. The hypotenuse is the side that has an angle of 90° on it. Always, the hypotenuse is the longest side. The remaining two inner angles add up to a total of 90°.

Right triangles are triangles with one of the internal angles at a right angle of 90 degrees. Since a triangle's three interior angles sum up to 180 degrees, a right triangle's three interior angles must always add up to 90 degrees since one of them is always 90 degrees (they are complementary).

1. The length of the altitude is 15 units.

2. The perimeter of trapezoid ABCD is 132 units.

An altitude is the vertical height of a given object from the sea level. This is majorly a height reached by an object to the sea level as a reference.

The perimeter of a trapezoid is the sum of all its sides.

From the question;

1. To determine AE,

DE = (DG - EF)/ 2

     = (22 - 6)/ 2          (since AB = EF = 6)

     = 8

DE = 8 units

The altitude AE can be determined by applying the Pythagorean theorem to triangle ADE. So that;

/hyp/^2 = /opp/^2 + /adj/^2

AD^2 = DE^" + AE^2

17^2 = 8^2 + AE^2

289 = 64 + AE^2

AE^2 = 225

AE = 15

Thus the length of the altitude is 15 units.

2. To determine the perimeter of the trapezoid, we have;

AE = (AD - EF)/ 2

     = (58 - 16)/ 2           (since BC = EF = 16)

     = 21

AE = 21 units

So that from triangle ABE, applying the Pythagorean theorem to determine the value of AB, we have;

/hyp/^2 = /opp/^2 + /adj/^2

AB^2 = BE^2 + AE^2

         = 20^2 + 21^2

AB = 841^1/2

AB = 29

Perimeter of the trapezoid = 29 + 16 + 29 + 58

                       = 132 units

Thus, the perimeter of the trapezoid is 132 units.

The area of a shape is the amount of space, the shape can occupy. The equation to calculate the value of x is: [tex](e)\ x^2 + 11x -42= 0[/tex]

The space on the border is given as:

[tex]Top = 2[/tex]

[tex]Others = 3[/tex]

So, the dimension of the sheet of paper is:

[tex]Length = x + 2 + 3[/tex]

[tex]Length = x + 5[/tex]

[tex]Width = x + 3 + 3[/tex]

[tex]Width = x + 6[/tex]

The area of the sheet is then calculated as follows:

[tex]Area= Length \times Width[/tex]

[tex]Area= (x + 5) \times (x + 6)[/tex]

Open brackets

[tex]Area= x^2 + 5x + 6x + 30[/tex]

[tex]Area= x^2 + 11x + 30[/tex]

From the question, we understand that the area of the sheet is [tex]72cm^2[/tex]

So, the equation becomes

[tex]x^2 + 11x + 30 = 72[/tex]

Subtract 72 from both sides

[tex]x^2 + 11x + 30 -72= 0[/tex]

[tex]x^2 + 11x -42= 0[/tex]

Hence,

[tex](e)\ x^2 + 11x -42= 0[/tex] can be used to calculate the value of x

Step-by-step explanation:

This is because the sound of the foot striking the floor is being transmitted through the air. The sun's light is absorbed when it strikes the sidewalk.

What is absorption and transmission?

Absorption is the process or action by which one thing absorbs or is absorbed by another.

The act of sending something, such as a cold or a message, or the component of a machine that transfers power from the engine to the moving parts is known as transmission.

Because of the air pressure, people can hear when their foot strikes the ground. In a similar manner, when sunlight strikes a sidewalk, it warms up as a result of absorbing the heat.

An increasing exponential function is defined as follows:

y = a(1 + r)^x.

For which the parameters are given as follows:

Her sample is of 10 grams, and the amopunt of goo increases by 100%, hence the parameter values' are given as follows:

a = 10, r = 1.

Thus the exponential function is defined as follows:

y = 10(2)^n.

Then the amounts are given as follows:

A decreasing exponential function is given as follows:

y = a(1 - r)^x.

The goo shrinks by 75% every hour, hence:

r = 0.75.

The amount after n hours is of 10(2)^n, hence the shrinking function is given as follows:

? = -1/2    dark gray box = - 1

y = -1/2 x - 1       or

y = -0.5x - 1

Step-by-step explanation:

The place to start is at 0.

When x = 0 then y = - 1

That means that the second box (the dark gray one) is - 1

So far what you know about the equation is

y = ?x - 1

We need to check two more points.

x =  4

y =  - 3

- 3 = ? 4 - 1             Add 1 to both sides

-3 +1 = ?4 - 1 + 1     Combine   The -1 and + 1 Cancel

-2 = ?4                   Divide by 4

-2/4 = ?

?  = -1/2 or - 0.5

Now we need 1 more point to check the result

Let x = 2. Do we get - 2 for y

y = -1/2 * 2 - 1

y = -1 - 1

y = - 2       just as it should

The total cost of the item after the sales tax of 8 % is given by the equation t = 1.08p , where p is the initial price of the item

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

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost price of the item be represented as t

Let the initial cost price of the item be represented as p

Now , the sales tax percentage = 8 %

So , the equation will be

The total cost price of the item t = sales tax percentage ( initial cost price of the item ) + initial cost price of the item

Substituting the values in the equation , we get

The total cost price of the item t = 8 % ( p ) + p

On simplifying the equation , we get

The total cost price of the item t = ( 8/100 ) p + p

The total cost price of the item t = 0.08p + p

The total cost price of the item t = 1.08p

Hence , the equation is t = 1.08p , where p is the initial price of the item

The reason why the cousin's procedure for getting the x and y intercepts work is because they represent the definition of those points on a graph.

The x-intercept of a graph or function simply refers to the point at which the graph crosses the graph crosses the x-axis or the point at which y = 0. In a similar manner, the y-intercept simply refers to the point at which the graph crosses the y-axis or simply the point at which x = 0.

Now, we are given the equation of the line as;

5x + 4y = 14

The general form of equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Rewriting the equation of the line in slope intercept form is;

y = -⁵/₄x + ⁷/₂

Now, the reason why we plug in 0 for x to get the y-intercept is because when x = 0, that is only where we can get the y-intercept as the corresponding value of x will be traced to 0.

Similarly,  the reason why we plug in 0 for y to get the x-intercept is because when y = 0, that is only where we can get the x-intercept as the corresponding value of y will be traced to 0.

If the dimensions of the cylinder are doubled, then by 4 factor the surface area changed

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface.

The radius of cylinder is r=8 inches

Height is 0.5 feet.

Surface area of cylinder=2πr(r+h)

We know that 0.5feet=6 inches

Suface area of original cylinder=2πr(r+h)

=2×π×8(8+6)

=224π

Now the dimensions are doubled ,so r=16 inches , h=12 inches

Suface area of changed cylinder=2πr(r+h)

=2π×16(16+12)

=32π×(28)

=896π

=4(224π)
