joanne graphed a linear funtion with a slope of -4 passing through 0,-2 nick graphed the function y=-2x - 4

Answer:

It has reflectional symmetry with four lines of symmetry.

Step-by-step explanation:

======================================================

Explanation:

Choice A is false since it does have rotational symmetry. See choice B.

Choice B is close, but the "90 degrees" needs to be "45 degrees". Each 45 degree rotation of the figure has the "before" and "after" be the same.

Choice C is one of the answers. There's a vertical line of symmetry, and a horizontal one as well.  Then there are two diagonal lines of symmetry. Each goes through the center. A line of symmetry is a mirror line to allow us to reflect one half over this line to get the other half.

Choice D is another answer. It has point symmetry since we can pick any point on the figure and reflect it over the center point, to land on a corresponding image point on the opposite side of the figure. For example, the northern most point reflects over the center to land on the southern most point.

The area of the rectangle would be 4.90 units which is shown in the given graph.

The area of a rectangle is defined as the product of the length and width.

The rectangle is given which has:

verticals at  A(-4,0), B(-3,1) C(0,-2) and D(-1,-3)

The length of segment AB = √ (-3 - (-4))² + (1 - 0)² = √ (1 + 1) = √2

The length of segment BC = √ (-3 - 0)² + (1 - (-2))² = √ (9 + 3) = √12

The area of the rectangle = length of segment AB x length of segment BC

The area of the rectangle = √2 x √12

The area of the rectangle = √24

The area of the rectangle = 4.90 units

Thus, the area of the rectangle would be 4.90 units

EXPLANATION

The equation of the function can be represented as shown as follows:

-This function is discrete.

-If we have 20 gallons, we can obtain the number of miles by plugging in the value into the equation, as shown as follows:

Dividing both sides by 12:

Simplifying:

We can make 1.67 miles with 20 gallons.

-The domain of the function are all the Real Numbers and the Range are also the Real numbers.

-Finally, drawing the graph of the function:

The points of the table are the following:

Gallons Miles

6 72

8 96

-We can get the number of gallons needed to, make 500 miles by plugging the value 500 into the equation, as shown as follows:

Isolating m:

Simplifying:

The number of gallons to make 500 miles is equal to 41.7 gallons

Finally, labeling the graph:

To solve the question we would need to state some facts.

1) In measurements, there are one thousand millimeters in a meter.

2) Also one thousand milligrams equals one gram

3) However one milligram is not equal to one milliliter

Answer: 1mg is equal to 1ml is not true

The vertex of the function is (1, -25) Correct

Because

f(x) = (x + 4)(x - 6)

Substitution

-25 = (1 + 4)(1 - 6)

Simplification

-25 = (5)(-5)

Result

-25 = -25 As both sides of the equation are equal this option is true

5) The graph is negative on the entire interval - 4 < x < 6 because the graph is below the x-axis

If equation of the height is h = -16[tex]t^2[/tex]+150, then the time taken for the object to be 6 feet above the valley floor is 4.28 seconds

The equation of the height h = -16[tex]t^2[/tex]+150

Where h is the height

t is the time taken

We have to find the time taken for the object to be 6 feet above the valley floor

The height = -150+6

= -144

Substitute the values in the equation

-16[tex]t^2[/tex]+150 = -144

-16[tex]t^2[/tex] = -144-150

-16[tex]t^2[/tex] = -294

[tex]t^{2}[/tex] = 18.375

t = 4.28 seconds

Hence, if equation of the height is h = -16[tex]t^2[/tex]+150, then the time taken for the object to be 6 feet above the valley floor is 4.28 seconds

Answer: 529.3 downloads

Explanation:

Standard version size = 2.1 MB

High quality version = 4.7 MB

The high-quality version was downloaded twice as often as the standard version

H = 2 S

The total size downloaded for the two versions = 3335 MB

H + S = 3335

We have the system:

H = 2 S (a)

H + S = 3335 (b)

Put A into B

(2S ) + S = 3335

3S = 3335

S= 3335/3

S= 1,111.67 MB

Divide the total MB of standard versions by the size of each standard version.

1,111.67 / 2.1 = 529.3 downloads

Step-by-step explanation:

This question tests on the the concept of Unit Conversion.

Unit Conversions involving converting values into per unit values.

Example: 15 apples in 3 days = (15 ÷ 3) apples per day = 5 apples per day

For this Question, we are given:

5 people per 3 cups of rice.

We are asked to find the number of cups of rice that 35 people can finish.

5 people = 3 cups

(5 ÷ 5) people = (3 ÷ 5) cups

1 person = 0.6 cups

(1 × 35) people = (0.6 × 35) cups

35 people = 21 cups

The weight of the largest piece of pie is 250 gram.

Let the weights of others be illustrated as x.

Therefore, the weight of the largest weight is the addition of the others weight. This will be:

= x + x + x = 3x

Therefore, the weights will be:

3x + x + x + x = 500

6x = 500.

Divide

x = 500 / 6

x = 83.33.

The larger weight will be:

The total score in the basket game = 139

Falcons score = 9x + 22

Maverick score = 16x - 8

Therefore,

139 = 9x + 22 + 16x - 8

collect like term

139 - 22 + 8 = 9x + 16x

125 = 25x

divide both sides by 25

Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

Proportional relationships are relationships between two variables where their ratios are equivalent. A straight line represents a proportional relationship. Mathematically -

y = kx + c

(y - c)/x = k         [k is constant]

or

y = kx

k = y/x                [k is constant]

Given is the following data -

[x]  42.5      29.2     69.4

[y]   21.25     14.6      34.7

In order to find if the given coordinates represent proportional relationship, plot these coordinates on graph. If the by joining the coordinate points, we get a straight line, then it represents a proportional relationship. Graph is attached with the answer. It can be seen that its graph is a straight line and hence represents a proportional relationship.

Now, the ratio of [y] by [x] -

m = (21.25 - 14.6)/(42.5 - 29.2) = 6.65/13.3 - 0.5 = 1/2

Therefore, we can say that, Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

An accountant’s ethical code of conduct represents the moral values, principles, and rules that accountants should have.

The ethical codes of conduct of AICPA and IFAC are the two main codes most countries adopt to guide their members on how to deal with accounting information from an ethical perspective.

The fundamental principles within the Code – integrity, objectivity, professional competence and due care, confidentiality, and professional behavior – establish the standard of behavior expected of a professional accountant (PA) and it reflects the profession’s recognition of its public interest responsibility.

The common thing in all accounting codes of conduct is that "they all go into great detail on the responsibilities of accountants."

From the given figure the value of x is 6 and the measure of angle 3 is 57°.

From the given figure, m∠4=(20x+3)° and m∠6=(9x+3)°.

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

22). From the given figure

m∠4+m∠6=180° (Coointerior angles sum is equal to 180°)

(20x+3)°+(9x+3)°=180°

⇒ 29x+6=180

⇒ 29x=174

⇒ x=6

m∠4=(20x+3)°=123°

m∠3+m∠4=180° (Adjacent angles sum is equal to 180°)

m∠3+123=180

m∠3=57°

23). From the given figure

m∠3=m∠6 (Alternate interior angles are congruent)

x+10 = 4x-20

⇒ 3x=30

⇒ x=10

Now, m∠6=4x-20

=20

m∠6+m∠8=180° (Adjacent angles sum is equal to 180°)

Answer:

90%

Step-by-step explanation:

To find the percent of increase in the height of the tree, we need the change of the height and the original height (40 feet)

The change of height = 76 - 40 = 36 feet

Now, we need to divide the change by the original height to find the percent of increase.

36/40 = 9/10

9/10, which is then 90%.
