The formula for calculating Alex's earnings from his employment at the theme park is 8(40 x 9 + 100) = 8(360 + 100) = 8(460) = $3,680.

Given: that the plane ticket costs $2,200 and that y = 11.5x gives the function that represents the potential earnings Alex may make from the tech internship, the inequality that reflects the maximum number of hours Alex can work at the internship follows.

He puts in 20 hours every week at the internship, which translates to 160 hours of work over the course of 8 weeks.

Given that the internship pays $11.5 an hour for 160 hours, her earnings of 11.5 x 160 = $1,840 will not be sufficient to cover the cost of the plane ticket.

A few of the theme park employment that are available in this sector include costume character work, ride technician, admissions attendant, lifeguard, and gaming attendant. Workers at concession stands must be swift to prevent long queues and receive cash for food and drinks.

Hence, Alex's employment at the internship will not generate enough income to pay for the ticket.

Way #2: The graphing calculator method

hi

A = 6x^(2)+4x+3*y + 6y + y^(2)

A= 6x²+y²+4x+9y

The range of the function is {-11, -9, -7, -5}.

The given function is g(x)=x−13.

We need to find the range of g(x).

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Now, put x=2,4,6,8 in the given function and find the range of function.

So, g(2)=2−13=-11

g(4)=4−13=-9

g(6)=6−13=-7

g(8)=8−13=-5

Answer:

f(x) = 12x+35

f(5) = 95 pages written at 5 months

Step-by-step explanation:

Step 1: write the slope intercept equation

f(x) = mx+b

f(x) = the value of the equation at month x

m = slope of the linear equation (pages written PER month)

x = the month

b = intercept of the equation (pages already written)

Step 2: relate given information to the variables

m = 12 pages per month

b = 35 pages already written

Step 3: update equation

f(x) = 12x+35

Step 4: solve for x = 5 months

f(5) = 12(5) + 35 = 60 + 35 = 95

% is a relative number that is used to represent hundredths of any quantity. Since one percent (1%) equals one tenth of something, 100 percent denotes the entire amount, and 200 percent denotes twice the amount mentioned percentage.

1 - Start : 3 end : 10

  formula for finding percentage increase is = [tex]\frac{end - start }{start } * 100[/tex]

so substituting value in the formula ;

       that is equal to = [tex]\frac{10-3}{3} * 100[/tex]

                                 = [tex]\frac{7}{3} * 100[/tex]

                                 = 233.33% increase

2 - Start : 9  End : 20

      directly substituting the values in the above mentioned formula

                                            = [tex]\frac{20-9}{9} * 100[/tex]

                                            = [tex]\frac{11}{9} * 100[/tex]

                                            = 122.22% increase

3 - Start : 100 end : 85

             plugging in the values = [tex]\frac{85-100}{100}*100[/tex]

                                                   = [tex]\frac{-15}{100} * 100[/tex]

Using relations in a right triangle, it is found that

The height of the tree is of 91.6 meters.

The graph for this problem is given at the end of the answer.

The relations in a right triangle are given as follows:

From the diagram graphed, we can build two relations involving the tangent of the angles, as follows:

From the smaller right triangle:

tan(43º) = h/x

0.9325 = h/x

x = (1/0.9325)h.

x = 1.0724h (we want to find h, hence we write x as a function of h).

From the larger right triangle:

tan(38º) = h/(x + 19).

tan(38º) = h/(1.0724h + 19).

0.7813 = h/(1.0724h + 19).

Applying cross multiplication:

h = 0.7813(1.0724h + 19).

h = 0.8379h + 14.8447.

0.1621h = 14.8447

h = 14.8447/0.1621

h = 91.6 meters.

The factors of the equation is  (x - 5)  (x + 2).

Given the equation is x²-3x-10

we are asked to factorize the equation.

Factorization is the process of identifying two or more expressions whose product is an algebraic expression. It is often referred to as finding the factors of an expression. Finding two or more expressions whose product is the given expression—known as factorization—is the process of breaking down algebraic expressions. A factor is any number that divides the given number by itself without leaving any remainder. It simply implies representing a number as the product of two other integers.

x²-3x-10

x² - 5x + 2x - 10

x(x - 5) + 2(x - 5)

(x - 5)  (x + 2)

Thus, the factorization of the given expression  x²-3x-10

= (x - 5)  (x + 2)

Hence we get the factors as (x - 5)  (x + 2)

Answer:

To factor the quadratic expression a2 - 3x - 10, we need to find two numbers that multiply to give -10 and add to give -3. These numbers are -5 and 2. Therefore, we can write:

a2 - 3x - 10 = (a - 5)(a + 2)

So the factors of the quadratic expression a2 - 3x - 10 are (a - 5) and (a + 2).

The quadratic function is defined as follows:

- 2 / 3 x² + 7 / 3 x + 8

The quadratic function has the following sets of values below:

(0,8) (2,10) (3,1).

The quadratic function is represented as follows:

f(x) = ax² + bx + c

using  (0,8)

8 = a(0)² + b(0) + c

8 = c

Therefore, using (2, 10)(3 , 1).

f(x) = ax² + bx + c

10 = a(2)² + b(2) + 8

10 - 8 = 4a + 2b

2 = 4a + 2b

1 = 2a + b

1 = a(3)² + b(3) + 8

1 = 9a + 3b

Hence, combine the equations,

2a + b = 1

9a + 3b = 1

multiply equation(i) by 3

6a + 3b = 3

9a + 3b = 1

3a = - 2

a = - 2 / 3

Therefore,

9a + 3b = 1

9(- 2  / 3) + 3b = 1

-6 + 3b = 1

3b = 7

b = 7 / 3

Therefore, the quadratic function is defined as follows:

1. The value of x is 14°

2. The value of x is 23°

3. The value of x is 22.5°

From the question, we are to determine the value of x in the given diagrams.

1.

∠ CBA = 180° - 6x (Linear pair theorem)

and

m ∠BAC + m ∠CBA = m ∠FCB (Exterior angle theorem)

Thus,

2x + 180° - 6x = 124°

180° - 4x = 124°

180° - 124° = 4x

56° = 4x

x = 56/4

x = 14°

Hence, the value of x is 14°

2.

m ∠ABE = 4x (Alternate angles theorem)

m ∠ABD + m ∠ABE + m ∠EBF = 180° (Sum of angles on a straight line)

x + 4x + 65° = 180°

x + 4x = 180° - 65°

5x = 115°

x = 115°/5

x = 23°

Hence, the value of x is 23°

3.

m ∠EAB = 2x (Vertical angles theorem)

m ∠AEB = 180° - 4x (Linear pair theorem)

m ∠ABE = 180° - 6x (Linear pair theorem)

m ∠EAB + m ∠AEB + m ∠ABE = 180° (Sum of angles in a triangle)

Thus,

2x + 180° - 4x + 180° - 6x = 180°

180° + 180° - 180° = 6x + 4x -2x

180° = 8x

x = 180°/8

x = 22.5°
