The graph is showing the quadratic function.

What is Quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must have at least one second-degree term. It performs algebraic operations.

As, the linear function have graph consist of straight line.

Then, The quadratic function has the shape of a parabola and has the variable squared.  

and, exponential function have raising curve or falling curve.

Part A

The length (l) of a rectangular box is 5 centimeters more than twice its width (w).

Write an equation to represent the length of the rectangular box.

Part B

Find the length of the box if its perimeter is 100 centimeters.

Answers

Answer:

length of rectangular box = 2[w] + 5

length of rectangular box = 35 cm

Step-by-step explanation:

Given:

length (l)

width (w)

Perimeter = 100 centimetre

Computation:

Part A;

length of rectangular box = 2[width] + 5

length of rectangular box = 2[w] + 5

Part B;

Perimeter = 2[l+w]

100 = 2[2w + 5 + w]

100 = 6w + 10

w = 15 cm

length of rectangular box = 2[w] + 5

length of rectangular box = 2[15] + 5

length of rectangular box = 35 cm

Find the largest number which divides 94 and 76, leaving a remainder of 4.​

Answers

Answer:

6 for 76 and 5 for 94

Step-by-step explanation:If you divide 76 with 6 the quotient will be 12 and the remainder will be 4 and if you divide 94 by 5 the quotient will be 18 and the remainder will be 4. Thank me later .

The largest number which divides 94 and 76, leaving a remainder of 4. is 18.

It is required to find the largest number.

What is factor?

A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.

Given:

we have to  find the largest number which divide 94 and 76 leaving remainder 4 in each case.

According to given question we have

so let us subtract 4 from 94 and 76.

⇒ 94−4=90

⇒ 76−4=72

now lets find the HCF

⇒ prime factorization of 90 = 2 × 3 × 3 × 5

  prime factorization of 72 = 2 × 2 × 2 × 3 × 3

now lets take out the common factors from both the cases

⇒ 2,3 and 3

x=2*3*3=18

∴ 18 is the number which will divide 94 and 76 leaving remainder 4 in each case.

Therefore, the largest number which divides 94 and 76, leaving a remainder of 4. is 18.

What is the center of the circle with equation x^2 + y^2 - 10x +6y-2= 0

Answers

Answer:

C(5, -3)

Step-by-step explanation:

Given the equation of circle;

x² + y² - 10x + 6y - 2 = 0

The general equation for a circle is given by the formula;

x² + y² + 2gx + 2fy + c = 0

Where the center is C(-g, -f)

To find the center, we would compare the two equations;

For the value of g.

2gx = -10x

2g = -10

g = -10/2

g = -5

To find the value of f.

2fy = 6y

2f = 6

f = 6/2

f = 3

Therefore, the center C(-g, -f) = (-(-5), -(3))

C(-g, -f) = C(5, -3).

One year, the population of a city was 160,000. Several years later it was 140,800. Find the percent decrease.

Answers

Answer:

Percent decrease in population = 12%

Step-by-step explanation:

Given that:

Population of city = 160,000

Population of city after several years = 140,800

Difference= 160000 - 140800 = 19200

Percent decrease = [tex]\frac{Difference}{Population} * 100[/tex]

Percent decrease = [tex]\frac{19200}{160000}*100[/tex]

Percent decrease = 0.12 * 100

Percent decrease = 12%

Hence,

Percent decrease in population = 12%

If a pound of barley costs $8, how many ounces can be bought for $2.55?

Answers

Answer: I believe the answer would be 5.1 ounces...

Step-by-step explanation:

To get this answer I used a proportion and transformed pounds into ounces. 1lb=16oz

x/16= 2.55/8

Cross multiply....

8x=40.8

And simplify!

x=5.1

So for $8 you can get a pound, for $2.55 you can get 5.1 ounces (or 5 ounces if needed in whole numbers)

A local hair salon has 6 2/3 gallons of shampoo to split among 5 hairdressers. How much shampoo will each hairdresser receive?

Answers

Answer:

1 1/3 gallons of shampoo

Step-by-step explanation:

The above question is calculated as:

5 hairdressers = 6 2/3 gallons of shampoo

1 hairdresser = x gallon

We cross Multiply

5 hair dressers × x gallon = 6 2/3 gallons × 1 hair dresser

x gallon = 6 2/3 gallons × 1 hair dresser/5 hair dressers

x gallons = 6 2/3 gallons ÷ 5

x gallons = 20/3 gallons ÷ 5

= 20/3 × 1/5

= 4/3

= 1 1/3 gallons of shampoo

Therefore, each hair dresser would receive 1 1/3 gallons of shampoo

Jenna is at a fair with four friends. They all want to ride the roller coaster, but only three people can fit in a car. How many different groups of three can the five of them make

Answers

Answer:

They can make 10 different groups of three.

Step-by-step explanation:

The order in which the people are in the car is not important, so we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different groups of three can the five of them make?

Combinations of 3 from a set of 5. So

[tex]C_{5,3} = \frac{5!}{3!(5-3)!} = 10[/tex]

They can make 10 different groups of three.

Grace scored n points in her first basketball game of the season. She scored 8 more points in her second game than in her first, 3 fewer points in her third game than in her second, and 11 more points in her fourth game than in her third, scoring a total of 25 points in her fourth game. How many points did Grace score in her first game?

Answers

Answer:

Grace scored 9 points in her first game.

Step-by-step explanation:

In her first game, she scored n points.

She scored 8 more points in her second game than in her first

So n + 8.

3 fewer points in her third game than in her second

So n + 8 -3 = n + 5

11 more points in her fourth game than in her third

n + 5 + 11 = n + 16

A total of 25 points in her fourth game.

This means that:

n + 16 = 25

n = 9

So

Grace scored 9 points in her first game.
