Find the function of (0,6), (3,15.8) and (9.5,0)

Answers

The polynomic function that contains the points (0, 6), (3, 15.8) and (9.5, 0) is a quadratic function, whose model is y = -0.600 · x² + 5.066 · x + 6.

How to derive a polynomic function from given points

To determine the coefficients of a polynomic function we must know a set of distinct points, whose number is the same number of coefficients. In this case, we can derive a quadratic function, as quadratic functions have three coefficients:

y = a · x² + b · x + c     (1)

Now we substitute x and y in (1) and solve the resulting system of linear equations:

c = 6

9 · a + 3 · b + c = 15.8

90.25 · a + 9.5 · b + c = 0

Whose solution is a ≈ -0.600, b ≈ 5.066 and c = 6.

Answers

Answer:

b = 9

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20-b\\\frac{2}{3} b+5+b=20-b+b\\\frac{5}{3} b+5=20\\\frac{5}{3} b+5-5=20-5\\\frac{5}{3}b=15\\b= 15*\frac{3}{5} \\b= 9[/tex]

Answer:

[tex]b = 9[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20 - b[/tex]

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

[tex]\frac{2}{3} b + 5 - 5 = 20 - b - 5[/tex]

Simplify.

[tex]\frac{2}{3} b = 15 - b[/tex]

Add b to both sides.

[tex]\frac{2}{3} b + b = 15 - b + b[/tex]

Simplify.

[tex]\frac{2}{3} b + b = 15[/tex]

Multiply everything by 3 to remove the fractions.

[tex]3(\frac{2}{3}b+b) = 3(15)[/tex]

Simplify.

2b + 3b = 45

Simplify.

5b = 45

Divide 5 from both sides.

5b ÷ 5 = 45 ÷ 5

Simplify.

The volume of the box with a height of 10 inches and perimeter of 72 inches and width of w is 360w - 10w²

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let w represent the width of the box and v represents the volume, hence:

2(w + length) = 72

Length = 36 - w

Volume = w(36 - w) * 10

At a basketball game, 45% of people attending were supporting the home team, while 55% were supporting the visiting team. If 1413 people attending the game supported the home team, what was the total number of people attending the game?

Answers

divide the number of people supporting the home team by the percentage supporting the home team.

1413/0.45 = 3140


total people = 3,140

The total number of people attending the basketball game was 3140.

Let's denote the total number of people attending the game as "T."

According to the information given, 45% of the people were supporting the home team. Therefore, the number of people supporting the home team can be calculated as 45% of the total number of people: 0.45 * T.

We are also told that 1413 people supported the home team. So, we can write the equation:

0.45 * T = 1413

Now, let's solve for the total number of people attending the game (T):

T = 1413 / 0.45

T = 3140

Therefore, the total number of people attending the basketball game was 3140.

The height of the oak tree is 2.5 meters. what is the height of the oak tree in
inches?
(1 ft. 0.305 m)
show your work!

Answers

Answer:

98.4 inches

Step-by-step explanation:

1 meter is about 3.28 ft, meaning the oak tree is 8.2ft tall. (2.5*3.28)

1 foot is 12 inches, meaning the oak tree is 98.4 in tall. (8.2*12)

The height of the oak tree = 98.42 inches.

Given that,

The height of the oak tree is 2.5 meters

We have to find height of tree in inches.

Since we know that,

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Since we know that,

1 meter = 39.37

Then to find the height of oak tree in inches

Multiply 2.5 with 39.37

Therefore,

The height of the oak tree in inches = 2.5 x 39.37

                                                             = 98.42 inches

doubling the sum of 5 and a number is equal to the same number decreased by 2. what is the equation

Answers

Answer:

2(x + 5) = x - 2

⟹ x = -12

Step-by-step explanation:

Doubling the sum of 5 and a number is equal to the same number decreased by 2. What is the equation?

This word problem can be written as:

⟹ 2(x + 5) = x - 2

1. Distribute:

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

⟹ 2x + 10 = x - 2

2. Subtract x from both sides:

2x - x + 10 = x - x - 2

⟹ x + 10 = -2

3. Subtract 10 from both sides:

x + 10 - 10 = -2 - 10

⟹ x = -12

4. Check your work:

2(x + 5) = x - 2

2(-12 + 5) = -12 - 2

X+17=38 which property is included in the justification for the steps used to solve the equation?

Answers

Looking at the problem statement, the question is asking for us to determine the justification for the steps that are used to help solve the equation.  We are given the expression [tex]x + 17 = 38[/tex] to help achieve that goal.

Now that we know what we must do to finish this problem let us look how this equation can be solved.  When the term solve the equation is used it refers to us solving for the unknown, in this case being the variable x.  We can see that we have [tex]x + 17[/tex] on the left side and in order to solve the equation x must be alone so we would subtract 17 from both sides.

Subtract 17 from both sides

[tex]x + 17 = 38[/tex][tex]x + (17 - 17) = (38 - 17)[/tex][tex]x = (38 - 17)[/tex][tex]x = 21[/tex]

Therefore, we know that we must subtract the same number from both sides and this justification is known as the Subtraction Property of Equality.  This basically states that an equal value needs to be subtracted from both sides and it will become a new equation but with the same result.

Answer:

Subtraction Property of Equality

Step-by-step explanation:

Given: x + 17 = 38

Algebraic Properties:

Addition: If a = b, then a + c = b + c

Subtraction: If a = b, then a - c = b - c

Multiplication: If a = b, then ac = bc

Division: If a = b, then a ÷ c = b ÷ c

To solve this equation, we know that we need to isolate the variable x. To do this, we need to subtract 17 from both sides to isolate x.

This is also known as the subtraction property of equality, which states that when the same thing is subtracted from both sides of an equation, the equation will still be balanced. 

Subtract 17 from both sides:

x + 17 - 17  = 38 - 17

x = 21

Therefore, the subtraction property of equality is included in the steps used to solve this equation.

Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.

Answers

Answer:

Step-by-step explanation:

We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).

A line parallel to y=2x-1 will have the same slope, 2.

We can write y = 2x + b for the new line.  We need to find b.  We can use the given point in this equation and solve for b:

y = 2x + b

2 = 2(4) + b  for (4,2)

2 = 8 + b

x = -6

The parallel line to y=2x-1 that goes through point (4,2) is:

y = 2x-6

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

Parallel lines have the same slope.

Since the slope of the given line is 2, the slope of the line parallel to this one is also 2.

Now, figure out the y-intercept, c:

y=2x+c

We're given a point: (4, 2).

Where: 2 is the y-coordinate of the point, and 4 is the x-coordinate.

Now, substitute 2 for y and 4 for x:

[tex]\longmapsto\sf{2=2(4)+c}[/tex]

Simplify!

[tex]\longmapsto\sf{2=8+c}[/tex]

Subtract 8 from both sides of the equal sign:

c. $17,500.25
d. $19,430.84

Answers

Answer:

  a.  $19,224.92

Step-by-step explanation:

The dealer's cost will be the sum of the dealer's costs for the base car, its options, and the destination charge.

__

  cost for base car = 0.83 × $21,276 = $17,659.08

  cost for options = 0.80 × $1,219.80 = $975.84

  cost for destination charge = $590.00

The sum of the dealer's costs is ...

  $17,659.08 +975.84 +590.00 = $19,224.92

Barrons should estimate the dealer's cost to be $19,224.92.

There are no such integers. Odd + odd = even, and adding odd to that makes it odd again. But 64 is even.
