Answer:

Table C is a linear function. Table A is an exponential function. And lastly table B is a quadratic function.

Step-by-step explanation:

I know that table C is linear because it has a constant rate of change the whole entire time.

I know table A is exponential because of the way it drastically increases at the end.

And lastly I know that table B is quadratic because if I were to graph it and keep on placing points, it would make a parabola.

I hope I helped.

Answer:

y=3.50x+195

Step-by-step explanation:

y=3.50x+195

let y= total cost and x= square feet of carpet needed.

Answer:

If the coefficient of the squared term is positive, the parabola opens up. The vertex of this parabola is called the minimum point. If the coefficient of the squared term is negative, the parabola opens down. The vertex of this parabola is called the maximum point.

The graph opens upward, if the vertex of the quadratic function with a positive a value.

Given that, the quadratic function with a positive a value.

The vertex of the graph of a quadratic function is the highest or lowest possible output for that function. If you're looking at a graph, the vertex would be the highest or lowest point on the parabola. The easiest way to find the vertex is to use the vertex formula.

If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h, k). Any quadratic function can be rewritten in standard form by completing the square.

Therefore, the graph opens upward, if the vertex of the quadratic function with a positive a value.

Answer:

133 students would fill 2 buses and 3 vans

Step-by-step explanation:

Let x be the no. of students in each van

No. of students in 12 vans = 12x

No. of students in 14 vans = 14x

Let y be the no. of students in each bus

No. of students in 14 buses = 14y

No. of students in 12 buses = 12y

We are given that The senior class at Snellville rented and filled 12 vans and 14 buses with 796 students.

12x+14y=796 ---1

We are also given that General High rented and filled 14 vans and 12 buses with 738 students.

14x+12y=738 ---2

Plot 1 and 2 on graph

12x+14y=796 --- Green line

14x+12y=738 --- Purple line

Intersection point gives the solution

Intersection point=(x,y)=(15,44)

No. of students in 1 van = 15

No. of students in 3 vans = [tex]15 \times 3 = 45[/tex]

No. of students in 1 bus = 44

No. of students in 2 buses =[tex]44 \times 2 = 88[/tex]

So,Total no. of students in 3 vans and 2 buses = 45+88=133

Hence 133 students would fill 2 buses and 3 vans

Answer:

Hey!

Population at start : 8,230.

The rate of growth: r = 1.25

x - number of the years;

Answer:

B ) f ( x ) = 8,230 * ( 1.25 ) ^x where 1.25 is the rate of growth.

Step-by-step explanation:

Jessica develops a function to model this 8230(1.25)ˣ, where 1.25 is the rate of growth.

In an ideal condition where there is an unlimited supply of food and resources, the population growth will follow an exponential order.

Jessica has been tracking the population of a town.

The population was 8,230 last year and has been increasing by 1.25 times each year.

The population growth function is;

[tex]\rm f(x)=P_0 x^t[/tex]

Substitute all the values in the formula;

[tex]\rm f(x)=P_0 x^t\\\\f(x) = 8230 (1.25)^x[/tex]

Hence, Jessica develops a function to model this 8230(1.25)ˣ, where 1.25 is the rate of growth.

Answer:

A =28.26 inches^2

Step-by-step explanation:

The diameter is 6 so the radius is d/2 = 3

The area is given by

A = pi r^2

A = pi (3)^2

A = 9pi

Using 3.14 for pi

A = 9 * 3.14

A =28.26 inches^2

Answer:

~28.2743

Step-by-step explanation:

- The formula for a circle's area is:  Area= pi * radius^2

1.) We know the diameter is 6, and the radius is ALWAYS half of the diameter so the radius=3.

2.) Now we square the radius and multiply it by pi, which ends up as ~28.2743 as the area.

Answer: 5% approximately

Step-by-step explanation:

Jen earns $35,650 a year working for an electronics supplier and pays $1,749.80 in state income tax each year. To calculate the income tax rate, we divide the amount paid as tax by her annual income and then multiply by 100. This will be:

= 1749.80/35650 × 100

= 4.91%

= 5% approximately

The state's tax rate is 5%.

Step-by-step explanation:

If you were asking how many strawberries it would take to finish all 60, this is the answer, otherwise please rephrase the question.

If Charlotte ate 12 strawberries, you would have to do 12 x 4 which would be four times the amount of strawberries Charlotte ate, 12 x 4 = 48, Emily ate 48 strawberries, 48 + 12 = 60.

Charlotte eats 12 strawberries.

Let the amount of strawberries eaten by Charlotte be represented by x.

Since Emily eats four times the amount that Charlotte eats, then Emily will eat:

= (4 × x) = 4x.

Since Emily and Charlotte have a total of 60 strawberries, then this will be:

4x + x = 60

5x = 60

x = 60/5

x = 12

Therefore, Charlotte eats 12 strawberries.

In order for a line to be parallel the lines need to have the same slope.

Answer:

The answer would be y=3/4X+9

Step-by-step explanation:

It must have the same slope since it is parallel, so

m = 3/4

y - y1 = m(x - x1)

y - 0 = (3/4)[x - (-4)]

y = (3/4)(x + 4)

The mean absolute deviation (MAD) of her Math scores would be 1.2.

Step-by-step explanation:

Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1

7.1 - 5.4 = 1.7

7.1 - 6.4 = 0.7

7.1 - 7.8 = 0.7

7.1 - 8.8 = 1.7

Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2

Answer: [tex]x=\frac{31}{2}[/tex]

Step-by-step explanation:

[tex]2log_a(x+2)=log_a(x+9)+log_a(x-3)[/tex]

The first thing we are going to do is to get rid of the 2 in front of the first logarithm. To do this, we have the power property that says:

[tex]log_aX^n=nlog_aX[/tex]

Basically, the number in front, is the power of the number in the middle.

Let's rewrite this.

[tex]log_a(x+2)^2=log_a(x+9)+log_a(x-3)[/tex]

Now, in order to add logarithms with the same base (in this case "a"), we write the same base of the logarithm, and multiply their values.

[tex]log_a(x+2)^2=log_a(x+9)(x-3)[/tex]

Multiply the parentheses.

[tex]log_a(x+2)^2=log_a(x^2-3x+9x-27)[/tex]

Combine like terms;

[tex]log_a(x+2)^2=log_a(x^2+6x-27)[/tex]

Solve the binomial on the left side.

[tex]log_a(x^2+4x+4)=log_a(x^2+6x-27)[/tex]

When we have logarithms with same base, we equal their values.

[tex]x^2+4x+4=x^2+6x-27[/tex]

Subtract [tex]x^2[/tex]

[tex]x^2-x^2+4x+4=x^2-x^2+6x-27\\4x+4=6x-27[/tex]

Subtract 6x

[tex]4x-6x+4=6x-6x-27\\-2x+4=-27[/tex]

Subtract 4

[tex]-2x+4-4=-27-4\\-2x=-31[/tex]

Divide by -2.

[tex]x=\frac{-31}{-2}\\ x=\frac{31}{2}[/tex]

Answer:

x = -4 or 3

Step-by-step explanation:

[tex]x^{2}[/tex] + 6x - 2 = -[tex]x^{2}[/tex] + 4x + 22

2[tex]x^{2}[/tex] + 2x - 24 = 0

[tex]x^{2}[/tex] + x - 12 = 0

(x + 4)(x - 3)=0

x = -4 or 3
