Answer:

Explanation:

Here, we want to get the measure of the other three angles in a parallelogram

The angle rules in a parallelogram are:

i) Opposite angles are equal to each other

ii) The two adjacent angles add up to 180 degrees

From what we have, one of the angles is 24 degrees

The measure of the last two angles would be:

We will solve as follows:

So, the value that is a solution for the inequality is:

[Option A]

there is a zero at x = 1 (option D)

Explanation:

a) The graph shows it is going up (increasing towards both the y axis and x axis).

This graph will give a positive leading coefficient.

As a result, the equation will have a positive leading coefficient not a negative one.

b) zeros of a polynomial are the values of x when the line crossses the x axis.

From our graph, the line doesn't cross the x axis at x = 6.

As a result, there is no zero of -6.

Multiplicity tells us the number of times the number of times a factor occurs.

Since part of the statement is wrong, it makes the whole statement wrong

c) The degree of this graph is odd. Its equation is 3rd degree

d) From the graph, the line crosses the x axis at x = 1 (2nd tick line)

Each tick line represents 0.5

The zero is the value of x when it crosses the x axis

As a result the polynomial has a zero at x = 1

The correct option is there is a zero at x = 1 (option D)

Donna is right. 115° angle and ∠3 are supplementary.

From the figure, we are discussing about the 115° angle and ∠3.

Donna says that m∠3 = 65° because the 115° angle and ∠3 are supplementary. That is their sum = 180°.

From the figure, it is clear that the 115° angle and ∠2 are supplementary.

So ∠2 = 180° -115° = 65°.

Now ∠2 and ∠3 are corresponding angles formed between the parallel lines m and q. Since corresponding angles are equal, m∠2 = m∠3.

Thus m∠3 = 65°.

Thus 115° + m∠3 = 115° + 65° = 180°

As the sum of the 115° angle and m∠3 = 180°, they are supplementary.

Hence Donna is correct.

Luis said that 115° and ∠3 are alternate but they are not. Alternate angles are those which are formed in the interior and on the opposite sides of the transversal cutting two parallel lines. They are of same size. But here, m∠3 ≠ 115°.

So Luis is not right.

The triangles are not similar.

Triangles that are comparable to one another are those that have an equal number of corresponding sides and corresponding angles.

If the respective sides of two triangles are proportional and the corresponding angles are congruent, then the triangles are said to be comparable. To put it another way, similar triangles have the same shape but may differ in size. In addition, if the corresponding sides of the triangles are identical in length, the triangles are congruent.

Here, the ratio of the sides are not similar

AB/AC= 4/10 = 2/5

DE/DF= 8/19

Hence, 2/5≠8/19

therefore, the triangles are not similar.

Recall the definitions of the magnitude and direction of a vector:

Investment = $5,000

Price of the product or sale price = $3.49

Production cost = $2.16

Profit = 3.49 - 2.16 = $1.33

We need to sell X items to get our investment back, therefore

X * Profit = Investment

1.33 * X = 5,000

X = 5,000 / 1.33 =3759.4

Therefore you need to sell at least 3760 articles to break even

Additionally, if you want to make a $10,000 profit, then you need to sell those items plus Y more or in other words, you want to sell as many items to get your $5,000 investment plus $10,000

This is...

5,000 + 10,000 = K * (1.33)

15,000 = 1.33 * K

K = 15,000 / 1.33 = 11,278.2 ;

Therefore, you need to sell 11,279 items

The growth rate of real gdp per capita from 2019 to 2020 is 40%

Given,

The real gdp of an economy in 2019 = 100 billion = 100, 000, 000, 000

The real gdp of an economy in 2020 = 240 billion = 240, 000, 000, 000

The population in 2019 = 15 million = 15, 000, 000

The population in 2020 = 15 million = 15, 000, 000

Growth rate of real gdp per capita =( increased gdp × 100) / (initial gdp)

Here,

Initial gdp = 100,000,000,000 / 15,000,000 = 6666.67

Increased gdp = 240,000,000,000 / 15, 000, 000 = 16000

Now,

Growth rate of real gdp per capita =( increased gdp × 100) / (initial gdp)

Growth rate of real gdp per capita = (16000 × 100) / 6666.67 = 240

Weeks (w)     Amount remaining

6                          62

10                        20

From the question, we have the following parameters

Savings = $125

Bus fare = $10.5

The equation of the amount remaining is represented as

Amount remaining = Savings - Bus fare x Number of weeks

Substitute the known values in the above equation

So, we have the following equation

s = 125 - 10.5w

Where w represents the number of weeks

Also, we have

w = 6 and w = 10

So, we have

s = 125 - 10.5 * 6 = 62

s = 125 - 10.5 * 10 = 20

So, the table is

Weeks (w)     Amount remaining

6                          62

10                        20

In (a), we have

s = 125 - 10.5w

Express as a function notation

s(w) = 125 - 10.5w

See attachment for the graph

We have

s(w) = 125 - 10.5w

This gives

125 - 10.5w = 41

So, we have

10.5w = 84

Evaluate

w = 8

This means that the amount remaining after 8 weeks is $41

The equation of the parabola from its focus and vertex is 5x = 4y² .

A parabola is a mirror-symmetrical, roughly U-shaped planar curve. The same curves can be defined by a number of seemingly unrelated mathematical definitions, which all correspond to it.

A line and a point (the focus) are two components of one definition of a parabola (the directrix). There is less emphasis on the directrix. The parabola is the location of the endpoints in that plane that are equally spaced away from the directrix and the focus.

Another approach to define a parabola is as a conic section formed by the union of a right circular conical area with a plane parallel to another axis perpendicular to the conical surface.

from the figure the parabola is opening on the right side.

Hence the general equation of the parabola is is y² = 4ax

Now from the focus we get 4a = 5
