The x-intercepts and y-intercepts of the graph include the following:

x-intercept: B. -1.

y-intercept: D. none.

The equations for all vertical and horizontal asymptotes are as follows;

Vertical asymptote: x = 1.

Horizontal asymptote: y = 4.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

In Mathematics, an asymptote can be defined as a line which the graph of a given function approaches but would never touch. Additionally, the vertical asymptote of a function simply refers to the value of x which makes its denominator equal to zero (0).

Answer:

The distance between the student and the mirror is 7.5 feet.

Step-by-step explanation:

We can use similar triangles to solve this problem.

Let's call the distance between the student and the mirror "d". We can create a right triangle with the student's height as one leg, the distance "d" as the other leg, and the hypotenuse being the line from the student's eyes to the top of the school. Let's call the length of this line "h".

We can also create a second right triangle with the height of the school as one leg, the distance from the school to the mirror as the other leg, and the hypotenuse being the same line from the student's eyes to the top of the school.

Since these two triangles share an angle (the angle formed by the line from the student's eyes to the top of the school and the ground), they are similar triangles. This means that the ratios of their corresponding sides are equal.

We can set up the following proportion:

(student height) / d = (school height) / (distance from school to mirror)

Plugging in the given values, we get:

4.5 / d = 30 / 50

Simplifying, we get:

4.5 / d = 3 / 5

Cross-multiplying, we get:

3d = 22.5

Dividing by 3, we get:

d = 7.5

Therefore, the distance between the student and the mirror is 7.5 feet.

The distance of the student to the mirror, is 7.5 ft

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that, a mirror is placed outside a school the distance from the school to the mirror is 50 ft and the height of the school is 30 ft we need to find the distance of the student to the mirror,

This arrangement is creating two similar triangles, here we will use the properties of the similar triangles, to find the distance of the student to the mirror,

Therefore,

30 / 4.5 = 50 / d

d = 50 x 4.5 / 30

d = 225 / 20

d = 7.5

Hence, the distance of the student to the mirror, is 7.5 ft

The radius of the circle E is 27/5.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Let X be the intersection of the circles with centers B and E, and Y be the intersection of the circles with centers C and E.

Since the radius of B is 3, AX = 4.

Assume AE = p.

Then EX and EY are radii of circle E and have length 4 + p.

AC = 8, and ∠CAE = 60° because we are given that triangle T is equilateral.

Using the Law of Cosines on Δ CAE, we obtain

(6+p)² =p² + 64 - 2(8)(p) cos 60

The 2 and the cos 60 terms cancel out:

p² + 12p + 36 = p² + 64 - 8p

By answering the above question, we may state that Hence, when interest Kathleen retires, her total interest will be $10,389.

Divide the principal by the interest rate, the length of time, and other factors to arrive at simple interest. Simple return = principal + interest + hours is the marketing formula. This method makes it easiest to compute interest. The most typical technique to figure out interest is as a portion of the principle sum. He will only pay his share of the 100% interest, for example, if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you give it out, you must charge interest. Interest is often determined as an annual percentage of the loan total. The interest on the loan is this percentage.

[tex]FV = PV x (r/n + 1)(n*t)[/tex]

where: $6,000 is the initial investment's present value, or PV.

6.4% is the yearly interest rate at zero.

n = 12 is the number of times interest is compounded annually (monthly)

33 years are equal to t. (from age 32 to age 65)

When we enter the values, we obtain:

FV = $6,000 x (1 + 0.064/12)(12*33) FV = $6,000 x (1 + 0.00533)396 FV = $6,000 x 2.7315 FV = $16,389 FV = $6,000 x 2.7315 FV = $16,389.0

As a result, Kathleen's retirement account will be worth $16,389.0 when she turns 65.

The difference between the future value and the initial investment is the total interest that Kathleen will earn:

Total interest is equal to $16,389 minus $6,000

Each subscription costs $10 per month for a yearly commitment,

so the cost for one subscription for a year would be $10 x 12 = $120.

Therefore, the total cost for 400 subscriptions for a year would be $120 x 400 = $48,000.

In addition, they need 1 extra subscription for a different service for every two employees, so they need 20 / 2 = 10 extra subscriptions.

To solve for a hypotenuse you need to use the equation for the Pythagorean Theorem which states: [tex]a^{2} +b^{2}= c^{2}[/tex].

In this case, 36, and 77 are the two legs that make up this triangle.

We would insert these two numbers to replace a and b for when solving the equation.

Now you have [tex]36^{2}+ 77^{2}= c^{2}[/tex].

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
1296 + 5929 = 7725 or [tex]c^{2}[/tex].

After that, we'll make sure to add the terms on the first side and keep [tex]c^{2}[/tex] on the other and to also square root them giving this equation: [tex]\sqrt{7725} = \sqrt{c^{2}[/tex].

With that, your answer is 85 = X


Figuring out only if X is a Leg:

Figuring out only if X is Hypotenuse:
To solve for a leg you need to use the equation for the Pythagorean Theorem which states: [tex]c^{2}- b^{2}= a^{2}[/tex]

In this case, 36, is one of the two legs that make up this triangle while 77 is the Hypotenuse.

We would insert these two numbers to replace b and c when solving the equation.

Now you have [tex]72^{2} -36^{2} =a^{2}[/tex]

You then do the exponent operations for the terms that we know the values of and also add them up together to get this equation:
5929 - 1296 = 4633 or [tex]a^{2}[/tex]

After that, we'll make sure to subtract the terms on the first side and keep [tex]a^{2}[/tex] them on the other and also to square root them giving this equation:  
[tex]\sqrt{4633} =\sqrt{a^{2} }[/tex]

With that, your answer is 68.07 (rounded) = X
