we have that

the aprent function

f(x)=x^2

g(x) is a reflection over x -axis of the parent function with a vertical dilation

so

g(x)=-ax^2

Find the value of the leading coefficient a

looking at the graph

For x=1

the value of g(x) is -4

therefore

The range of the function is the values of y

Then to find it, look for the smallest and the greatest value of y of the graph of the function

From the given figure

The lowest value of y is -1

The highest value of y is 3

Then the range of the function is [-1, 3]

From the given information, since AB is congruent to BC then triangle ABC is issoceles,

therefore, the base angles measure the same and they are denoted by x. Since interior angles of any triangle add up to 180, we have

which gives

Then, each base angle measure 53 degrees.

On the other hand, since DA bisects angleEAC then angle DAC measure the same as angle EAD, that is,

Therefore, angleEAB is equal to

By substituting our last result, we have

then, the answer is 141 degrees

SOLUTION

Given the question in the image, the following are the soluton steps to answer the question.

STEP 1: Draw the given triangle

STEP 2: Write the given parameters

Since we do not know the measure of any of the two remaining angles, we cannot solve for the required sides and angles.

Hence, There is no enough information to solve the triangle

Please check that the expression for the cost you typed reflects what you read in the problem.

Isn't there a "square" in one of the "x" values of the cost equation?

Great. I see now the actual equation for cost to be:

Cost = 0.3 x^2 - 66 x + 13267.

The minimum unit cost will be given by the minimum of this quadratic function (a parabola) which has a minimum at the parabola's vertex. Notice this is a parabola with branches pointing UP because the coefficient of the term in x^2 is POSITIVE.

Recall then the equation for the x position of the vertex of a pparabola with equation of the form:

y = a x^2 + b x + c

the x-position of the vertex is: x = - b / (2a)

which in our case gives:

x of the vertex = - (- 66) / (2 * 0.3) = 110

Then, since the x values represent the number of cars that are made , we now that that minimum occurs when the number of cars produced is 110.

We replace this value in the cost equation and get:

Cost = 0.3 (110)^2 - 66 (110) + 13267 = 9637

Then, the unit cost for making the 110 cars is $9637, which is in fact the minimum value we were looking for.

The value of x is 9

Given the equation:

Multiply both sides by 2(x-8)

Divide both sides by 8

Finally, add 8 to both sides

Ok, so it takes Mike 40 minutes to work on 6 pages. Let's calculate how many he types in 1.5 hours.

In order to calculate that, we'll use a cross product. But first, let's see how many minutes 1.5 hours are correspondent to:

1 hours - 60 minutes

1.5 hours - x

x= 60*1.5 = 90 minutes.

So:

40 min - 6 pages

90 min - x

40x = 6*90

40x = 540

x= 13.5 pages

He will type and spell check 13.5 pages.

The group of points (1, 2). (5,2), (5,4), (7,6). (11, 6) (11,8) is not a function as it doesn't satisfy the condition that there is one and only one value in the image space for every element in the domain.

We have the points (5, 2) and (5, 4), which shows two values (y=2 and y=4) for the same point in the domain (x=5).

It also happens for (11, 6) and (11,8).

Step 1

graph inequality 1

a)Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

so

draw a line that passes trough P1 ( 0,2) and P2( -1,-1) and

b)shade below the line for a "less than" (y< or y≤).

so

Step 2

graph inequality 2

a)Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

so

draw a line that passes trough C ( 0,1) and D( -1,3) and

b)shade below the line for a "less than" (y< or y≤).

so

Step 3

finally, the solution is the intersection of the shaded areas,hence

Linear pair theorem:

In math, the linear pair postulate or linear pair theorem, says the same in mathematical terms. If two angles form a linear pair, then the measures of the angles add up to 180

Also,

Two angles are called supplementary when their measures add up to 180 degrees.

That is,

Hence,

Linear pair theorem :

∠1 is supplementary to ∠2

∠2 is supplementary to ∠3

Congruent Supplements Theorem:

If two angles are supplements of the same angle (or congruent angles), then the two angles are congruent.

Since angles 1 and 3 are supplements of the same angle 2

Therefore,

With the statement above we can conclude that

∠1 ≅ ∠3 (congruent supplements theorem)

For the Rhombus you know that:

The opposite sides are parallel

All sides have equal length

Its diagonals bisect each other in right angles

You can calculate the area of the Rhombus by either mutiplying its whide by its length, and sice its 4 sides are of equal lenght, the area will be equal to the square of one of it's sides (s):

Or using its diagonals (d1 and d2) you can calculate its area as:

Given:

The following inequalities:

When 0 < a < 1

So, the denominator will be always < 1

so, all the fraction will be greater than 1

So, the first inequality True

when 0 < a < 1

The inequality will be true as a < 1/2

The inequality will be wrong when a >1/2

So, the second inequality is wrong

The inequality true when a >1

so, for 0 < a < 1, the inequality is wrong

So, the answer will be option A. I only

Let's compare the given function with the model for a quadratic equation:

Since the value of a is positive, the parabola has its concavity upwards, and the function has a minimum value.

The vertex of the parabolic equation y = (x+2) (x-2) is at (0,4) .

The given equation is of the form y = (x+2) (x-2).

This can be simplified using the properties of algebra:

y = x² - 4

the graph of the parabolic function y = x² - 4 is attached below.

a) The vertex of this graph is at (0,4) .

b) The graph opens upwards

c)The axis of symmetry of the graph is the y-axis or the line x = 0

e)For finding the maximum and minimum values we find the derivative of x.

y = x² - 4

dy/dx = 2x

at dy/dx = 0 , x = 0

at x=0 , y= - 4

hence the function has a minimum value at -4 and the maximum value of y is infinity.

f) Domain of the function (-∝ < x < ∝)

Daniel will not going to get a bag

why?

lets read the statement, a part of it

person who donates more than $5 to charity

the key word here is more,

daniel donates exact 5 dollars,

so he will not get a bag

Courtney cant get a bag, because she donates even less,

to get a bag you need to donate, according to the statement , 5 dollars or more,

so for example, you need to donate 5.01 dollars to get a bag

Harry sold 8 smalls cars out of 11 cars.

At the end of the sale He sold 33 cars.

In order to determine how many small cars did Harry sell in the week, you take into account that the proportion of small cars for each sale is 8/11.

To find the total small cars sold in the week you multiply the proportion of small cars by the total cars sold in the week, just as follow:

(8/11)33 = 8(33/11) = 8(3) = 24

Hence, the small cars sold during the week were 24.

c. 24

The translations are movements to the triangle in each of these directions:

There were two translations in this problem, listed as follows:

For the first translation, the triangle was moved down five units, hence the rule is given as follows:

y -> y - 5.

For the second translation, the triangle was moved right four units, hence the rule is given as follows:

The complete translation, obtained by the combination of each translation, is given as follows:

A box plot is a standardized way of displaying the distribution of data based on a five-number summary (“minimum”, first quartile (Q1), median, third quartile (Q3), and “maximum”).

The points at the beginning and end of the graph show the outliers (minimum and maximum values).

The outer lines on the left and right of the box show the first quartile and third quartile respectively, while the line inside the box is the median.

From the question, the third quartile (Q3) is the outer line to the right of the box, and its value is 29.
