Let's determine the statement which is not a characteristic of the linear parent function.

The linear parent function has the form:

We have the graph below:

The function has the following properties:

• The line goes through the origin.

• It has a range of all real numbers

• It has a domain of all real numbers

• It has a slope of 1.#

Therefore, the statement which is not a characteristic of the linear parent function is:

• The range is positive real numbers (y > 0).

ANSWER:

Answer:

Step-by-step explanation:

(4)

6 = hj + k ( subtract k from both sides )

6 - k = hj ( isolate j by dividing both sides by h )

[tex]\frac{6-k}{h}[/tex] = j

(5)

[tex]\frac{v}{w}[/tex] = 9 ( multiply both sides by w to clear the fraction )

9w = v ( divide both sides by 9 )

w = [tex]\frac{v}{9}[/tex]

(8)

A = [tex]\frac{1}{2}[/tex] bh ( multiply both sides by 2 to clear the fraction )

2A = bh ( divide both sides by h )

[tex]\frac{2A}{h}[/tex] = b

(10)

V = [tex]\frac{1}{3}[/tex] πr²h ( multiply both sides by 3 to clear the fraction )

3V = πr²h ( isolate h by dividing both sides by πr² )

[tex]\frac{3V}{\pi r^2}[/tex] = h

(12)

V = πr²h ( isolate r² by dividing both sides by πh )

[tex]\frac{V}{\pi h}[/tex] = r² ( take square root of both sides )

[tex]\sqrt{\frac{V}{\pi h} }[/tex] = r

Answer: -3/4>-11/12

Step-by-step explanation:

its a negative so there's more of the -3/4 than the -11/12 because the -11/12 is 2 more units below the -3/4

Answer:

it is C

Step-by-step explanation:

it cannot be A or B because ether angles 2 or 3 would have to be an obtuse angle, which neither of them is. So, this leaves C and D. It is not D because angles 2 and 3 are not corresponding (angles 2 and 4 are). This leaves option C as the only answer.

Option D is the answer

A graph of the image of figure Q'R'S'T' after a dilation of 2 units about the origin is: graph C.

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric figures such as triangles.

Note: Each interval on this graph represents 1 unit.

For the given coordinates, the dilation with a scale factor of 2 about the origin or a center of dilation (0, 0) should be calculated as follows:

Point Q (-2, -1) → Point Q' (-2 × 2, -1 × 2) = Point Q' (-4, -2).

Point R (-1, 2) → Point R' (-1 × 2, 2 × 2) = Point R' (-2, 4).

Point S (1, 0) → Point S' (1 × 2, 0 × 2) = Point S' (2, 0).

Point T (2, -2) → Point T' (2 × 2, -2 × 2) = Point T' (4, -4).

Answer:

136 divided by 12 you get 11.3 times 12 you get 136

Answer:

(136÷12) × 12 = 136

Step-by-step explanation:

You start with the numbers in the parentheses ( which look like "( )" ), which is 136÷12 which is 11.3

1.) 136÷12=11.33

Then you multiply it by 12 which will get you 136.

2.) 11.33× 12=136

Your final answer will be 136

Values of x in ascending orders is shown below.

The number of times a number has been multiplied by itself is referred to as an exponent. For instance, the expression 2 to the third (written as 2³) signifies 2 x 2 x 2 = 8. 2³ and 2 x 3 = 6 are not equivalent. Keep in mind that any number is itself when raised to the power of 1. Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion. To illustrate 3 x 3 x 3 x 3 in a straightforward manner, for instance, we could write it as 34, where 4 is the exponent and 3 is the base. It is claimed that the entire statement 34 has power.

Explanations:

Let the money borrowed be the Principal, P = $200

Interest rate, R = 2%

Number of years, T = 12 years

The total amount to pay back will be:

Amount = Principal + Interest

Let us calculate the Interest, using the formula:

Interest = $48

Amount = Principal + Interest

Amount = $200 + $48

Amount = $248

You will pay back $248 altogether

The angle vector 'a' makes with the positive x-axis is 90° to 180°.

A vector is a quantity that has magnitude as well as direction one such example of this is velocity where we describe speed and direction also.

Given a vector a with two components one in the x direction and another one in the y direction.

The x component of the vector ax < 0 which is on the 2nd quadrant and the y component of the vector is ay > 0 which we join to the tail of the component ax.

∴ The angle it makes with the positive x-axis is 90° to 180° as it is on the second quadrant.

The probability that maximum speed differs from the mean value by at most 2.5 standard deviations is 0.8473

Let the required probability that the maximum speed of mopeds differs from the mean speed by 2.5 standard deviations be given by P(U±2.5).

Mean speed U =46.7km/hr

P(46.7±2.5) = (44.2<= X <=49.2)

= P( 44.2<= Z <= 49.2)

= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)

= P( - 1.4286 <= Z <= 1.4285)

= P(1.4285) - P(-1.4285)

= P(1.43 ) - P(-1.43)

= 0.92364 - 0.07636

= 0.8473

Thus the probability that maximum speed differs from mean value by at most 2.5 standard deviations is 0.8473

the question is incomplete and the full question is "Mopeds (small motorcycles with an engine capacity below 50 cm3) are very popular in Europe because of their mobility, ease of operation, and low cost. Suppose the maximum speed of a moped is normally distributed with a mean value of 46.7 km/h and a standard deviation of 1.75 km/h. Consider randomly selecting a single such moped
