Find domain and range for f(x)=x^2-2x+2

The percent error is 4.17 %

Solution:

To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz

When Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz

To find: percent error

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

[tex]\% \text { error }=\frac{\text {approximate value}-\text {exact value}}{\text {exact value}} \times 100[/tex]

Here approximate value = 2.5 oz and exact value = 2.4 oz

[tex]\% \text { error }=\frac{2.5-2.4}{2.4} \times 100\\\\\% \text { error }= \frac{0.1}{2.4} \times 100 = 4.17[/tex]

Therefore percent error is 4.17 %

Option A: 3 is the right answer

Step-by-step explanation:

Given

[tex]f(x) = -2x-1[/tex]

In an ordered pair, the x-coordinate is the input to the function and y-coordinate is the output of the function on specified input.

In the given ordered pair,

x-coordinate is -2 so we will put it into the function to get the y-coordinate

So,

[tex]f(-2) = -2(-2)-1\\= 4-1\\=3[/tex]

3 will complete the ordered pair of the point on the graph

Hence,

Option A: 3 is the right answer

Answer:

A

Step-by-step explanation:

(x coodinate, y coodinate) = (x, f(x))

(-2, ___) is saying us x=-2, and question is asking y =?

f(x) = -2x -1

f(-2) = -2.-2 -1

f(-2)= 4 -1

f(-2) = 3

so, y= f(-2) = 2

(x, f(x)) = (-2, f(-2)) = (-2,3)

Answer:

GCF = 5

Step-by-step explanation:

Given:

The numbers are given as:

10, 30 and 45

A factor of a number is a number by which the given number is evenly divisible.

Example: 2 is a factor of 4 as [tex]4\div 2 =2[/tex]. So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.

Now, factors of 10 = 1, 2, 5, 10.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 45 = 1, 3, 5, 9, 15, 45.

So, the greatest common factor in all the three numbers is 5.

Hence, the greatest common factor of 10, 30 and 45 is 5.

Answer:

The Total number of car is 7 and The Total number of van is 5 .

Step-by-step explanation:

Given as :

The maximum capacity of car = 3 passengers

The maximum capacity of van = 8 passengers

Total number of vehicles = c + v = 12 vehicles

The maximum capacity of vehicles combination = 61 passengers

Let The Total number of car = c

Let The Total number of van = v

Now, According to question

c + v = 12            .........A

3 c + 8 v = 61            ............B

Now, Solving eq A and B

I.e (3 c + 8 v) - 3 × (c + v) = 61 - (3 × 12)

Or, (3 c - 3 c) + (8 v - 3 v) = 61 - 36

Or, 0 + 5 v = 25

∴ v = [tex]\dfrac{25}{5}[/tex]

i.e v = 5

So,The Total number of van = v = 5

Now Put the value of v into eq A

∵ c + v = 12    

So, c + 5 = 12

∴ c = 12 - 5

i.e c = 7

So,The Total number of car = c = 7

Hence,The Total number of car is 7 and The Total number of van is 5 . Answer

The student's question is about determining the number of vans owned by a company using a system of linear equations. By setting up two equations and using the elimination method, we find that the company owns 5 vans and 7 cars.

The question involves solving a system of linear equations to determine how many vans a company owns. We know that the company has a total of 12 vehicles, which are either cars with a capacity of 3 passengers or vans with a capacity of 8 passengers. The total capacity of all 12 vehicles combined is 61 passengers. To solve this problem, we will create two equations based on this information:

Using elimination to solve the equations:

Therefore, the company owns 7 cars and 5 vans.

Answer:

m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)

Step-by-step explanation:

In the diagram. check attach image

m∠A + m∠B + m∠C + m∠D = 360º.

Every quadrilateral can be decomposed (cut apart) into two triangles, each of whose angles' measures sum to 180º.

m∠A + m∠1 + m∠ 3 = 180º

m∠C + m∠2 + m∠4 = 180º

m∠A+m∠1+m∠3+m∠C+m∠2+m∠4 = 360º

therefore :

m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)

I think that the answer is A, because in the range, none of the numbers should be the same, and the numbers are all different in choice A

Multiply both sides by 2 to clear the fraction

5x - 3 = 6x + 16 ( subtract 6x from both sides )

- x - 3 = 16 ( add 3 to both sides )

- x = 19 ( multiply both sides by - 1 )

x = - 19

Answer:

The required points of the given line segment  are ( 9, - 2 ).

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( 4, 2 ) and point A is ( - 1, 6), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and  ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-  

M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1}  + y_{2}}{2}[/tex]   )

Here,

Let A ( - 1, 6 ), B ( x, y ) with midpoint M ( 4, 2 ) -

then by the midpoint formula M are-

( 4, 2 )  = ( [tex]\frac{ - 1 + x}{ 2}[/tex] ,  [tex]\frac{ 6 + y}{2}[/tex] )

On comparing x coordinate and y coordinate -

We get,

( [tex]\frac{ -1 + x}{2}[/tex] = 4 , [tex]\frac{ 6 + y}{2}[/tex]  =  2)

( - 1 + x = 8,  6 + y = 4)

( x = 8 + 1, y = 4 - 6 )

( x = 9, y = -2 )

Hence the required points  A are ( 9, - 2 ).

We can also verify by putting these points into Midpoint formula.

A: Its legs are congruent

Step-by-step explanation:

A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.

An isosceles trapezoid is a trapezoid with two congruent sides and congruent base angles.

An isosceles trapezoid is a trapezoid that has two congruent sides. In other words, the two non-parallel sides of an isosceles trapezoid are equal in length. The base angles of an isosceles trapezoid are also congruent. The parallel sides of an isosceles trapezoid are not equal in length.

For example, if a trapezoid has sides AB = 6 cm, BC = 5 cm, CD = 4 cm, and DA = 5 cm, then it is an isosceles trapezoid because sides BC and DA are congruent.

Given: Nails cost is $2.75 per pound

           Screw cost is $3.25 per pound

           Jerry has only $500 to spend on nails and screws.

           x represent quantity of nail bought and y represent quantity of screw    bought.

As given we know that Jerry has only $500 to spend, so the total cost has to be less than or equal to $500. It cannot go more than $500.

Remember, Total cost= [tex]\textrm{cost of goods per pound}\times quantity[/tex]

Option A

Length of CD is 10 inches

Solution:

The diagram is attached below

Given that, Circle A and circle B are congruent

CD is a cord of both circles

AB = 24 inches

Radius = 13 inches

To find: length of CD

Draw a straight line connecting A and C

AC represents the radius of circle. Also given that radius is 13 inches, So AC = 13 inches

Given in question that AB = 24 inches

Therefore from figure, AO = AB/2 = 24/2 = 12

AO = 12

Let "b" be the length of CO

Therefore, CD = CO + OD = b + b

AOC forms a triangle, so we can use pythogoras theorem

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition for triangle AOC

[tex]AC^2 = AO^2 + OC^2[/tex]

Substituting AC = 13 and AO = 12 and OC = b

[tex]13^2 = 12^2 + b^2\\\\b^2 = 169 - 144\\\\b^2 = 25\\\\b = 5[/tex]

Thus length of CD is:

CD = b + b = 5 + 5 = 10

Thus length of CD is 10 inches

Final answer:

Mr. Avery can arrange the 30 chairs in 5 rows of 6 chairs each or 3 rows of 10 chairs each to satisfy the conditions of having more than one row and the chairs per row being greater than the number of rows.

Explanation:

Mr. Avery can arrange the 30 chairs in the band room in multiple configurations but must satisfy two conditions: there must be more than one row and the number of chairs in each row must be greater than the number of rows. To find such arrangements, we can look for factors of 30 that adhere to these conditions. One possible arrangement is 5 rows with 6 chairs in each row. This satisfies the conditions because there are more than one row, and the number of chairs per row (6) is greater than the number of rows (5).

Another possible arrangement could be 3 rows with 10 chairs each. Here, the condition is also met since there are more than one row and the number of chairs per row (10) is greater than the number of rows (3). Mr. Avery must ensure there's enough space to move around, so he may need to rearrange the chairs to provide adequate pathways between rows.

The area of a 2D form is the amount of space within its perimeter. The width of the rectangle is 10/7 miles.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of a rectangle is the product of its length and its width, therefore, the width of the rectangle can be written as,

Area = Length × Width

Width = Area / Length

Given the area of the rectangle is 6/7 square miles, while the length of the rectangle is 3/5 miles, therefore, the width of the rectangle is,

Width = (6/7)/(3/5)

Width = (6×5)/(7×3) = 10/7
