Which triangle below represents a
90° rotation about the origin?

Answer:

Answer c is the correct one

The absolute value parent function is typically denoted as f(x) = |x|.

None of the given options matches the absolute value parent function.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The absolute value parent function is typically denoted as f(x) = |x|. Therefore, none of the given options matches the absolute value parent function exactly.

f(x) = [x], represents the greatest integer function, also known as the floor function, which returns the largest integer less than or equal to x.

f(x) = 1/x, is a rational function, which has a horizontal asymptote at y=0 and a vertical asymptote at x=0.

f(x) = x, is a linear function, which has a constant slope of 1.

f(x) = (x-1), is a linear function with a slope of 1, but it is shifted to the right by 1 unit.

Therefore,

The absolute value parent function is f(x) = |x|.

Answer:

Step-by-step explanation:

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis " ⇒ 2nd answer

Step-by-step explanation:

Lets revise some important rules

The corresponding sides of similar triangles have constant ratio

Dilation makes a triangle and its image similar

Reflection about x-axis change the sign of the y-coordinate of a point after reflected about the x-axis

Δ ABC and Δ A'B'C are similar after set of transformations has been

performed on Δ ABC to form Δ A'B'C'

∵ The vertices of triangle ABC are:

A = (-2 , -1) , B = (0 , 0) , C = (1 , -3)

∵ The vertices of triangle A'B'C' are:

A' = (-4 , 2) , B' = (0 , 0) , C' = (2 , 6)

∵ x-coordinate of point A = -2 and x-coordinate of point A' = -4

∵ y-coordinate of point A = -1 and y-coordinate of point A' = 2

∵ x-coordinate of point B = 0 and x-coordinate of point B' = 0

∵ y-coordinate of point B = 0 and y-coordinate of point B' = 0

∵ x-coordinate of point C = 1 and x-coordinate of point C' = 2

∵ y-coordinate of point C = -3 and y-coordinate of point C' = 6

∵ Each coordinate of the vertices A , B , C is multiplied by 2 to give

 the coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is dilated by scale factor of 2

∵ The signs of y-coordinates of the vertices A , B , C is opposite to

  the signs of y-coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is reflected about the x-axis

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis "

option b

slant height

Step-by-step explanation:

slant height of a pyramid is defined as a distance measure along a lateral face from a base of a triangle because hypotenuse of a right angle triangle is half on the base

distance from the center of the base to the point where the slant height segment

The line AB in the pyramid is the slant height of the pyramid.

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.

Given is a pyramid with AB labelled at one of its face, we need to determine the name for AB,

So, here AB is the slant height.

Slant height of a pyramid is defined as a distance measure along a lateral face from a base of a triangle because hypotenuse of a right angle triangle is half on the base distance from the center of the base to the point where the slant height segment.

Hence, the line AB in the pyramid is the slant height of the pyramid.

Answer:

Good credit will give you a better career.

Let the number be x

We use addiition sign

The expression is x+15

Let's split this problem into several steps:

Let's first put it into the point-slope form:

    ⇒ Point-slope form ⇒ [tex](y-y0)=m(x-x0)[/tex]

Consider the information given:

Let's plug the numbers in:

  [tex]y - 15=-4(x+4)\\[/tex]

To put this format into slope-intercept form, we will solve for y:

 ⇒as in, move everything else to one side and y by itself on the other

    [tex]y - 15=-4(x+4)\\y-15=-4x-16\\y = -4x-16+15\\y=-4x-1[/tex]

Thus the equation of the line is --> [tex]y = -4x - 1[/tex]

Answer: As a result, the angle between m and n is 45 degrees.

Answer:

Step-by-step explanation:

x^2 + 3

The domain is All Real x and the range is f(x) ≥ 3.

Find its inverse:

y = x^2 + 3

x^2 = y - 3

x = √(y - 3)

So f-1(x) = √(x - 3)

The domain is x  ≥ 3  and range is f(x) ≥ 0.

Answer:

Probability: The fraction you would expect to see a certain event occurring in many trials.

Ex: the probability of an event (blank) happening might be 0.75. This is more known as the normalized probability.

Chance: Chance is a synonym of probability, is usually expressed as a percentage

Ex: 100%

Odds: They are the ratios of probabilities, they can be defined in two different ways: odds in favor of an event (“odds on”) or against an event  (“odds against").

Ex: let's just say if the probability of an event occurring is 0.75, then the odds for it happening are 0.75/0.25 = 3/1 = 3 to 1 while the probability that it doesn’t occur is 1 to 3 against.

Answer:

(a)  3, 2, -3, -7, -12, -18, -25, -33 etc.

Step-by-step explanation:

Integer: whole numbers (including negatives)

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]

Question (a)

Given quadratic:  [tex]kx^2+5x+2[/tex]

[tex]\implies a=k, b=5\: \textsf{and}\:c=2[/tex]

You don't have to do this, but it is helpful to first find the range of k.  To do this, use the discriminant [tex]b^2-4ac[/tex].

If the quadratic has 2 real roots then [tex]b^2-4ac > 0[/tex]

If the quadratic has 1 real root then [tex]b^2-4ac = 0[/tex]

Therefore, set the discriminant to ≥ 0

[tex]\implies 5^2-4(k)(2)\geq 0[/tex]

[tex]\implies 25-8k\geq 0[/tex]

[tex]\implies -8k\geq -25[/tex]

[tex]\implies 8k\leq 25[/tex]

[tex]\implies k\leq 3.125[/tex]

As k is an integer, [tex]k\leq 3[/tex]

Given quadratic:  [tex]kx^2+5x+2[/tex]

[tex]\implies ac=k \cdot 2=2k[/tex]

[tex]\implies d+e=5[/tex]

So we need to find pairs of numbers that sum to 5 and multiply to a (negative or positive) even number, since [tex]ac=2k[/tex]

2 + 3 = 5  and  2 · 3 = 6   ⇒  2k = 6 ⇒ k = 3

1 + 4 = 5  and  1 · 4 = 4  ⇒  2k = 4 ⇒ k = 2

-1 + 6 = 5  and  -1 · 6 = -6   ⇒  2k = -6 ⇒ k = -3

-2 + 7 = 5  and  -2 · 7 = -14   ⇒  2k = -14 ⇒ k = -7

-3 + 8 = 5  and  -3 · 8 = -24  ⇒  2k = -24 ⇒ k = -12

-4 + 9 = 5  and  -4 · 9 = -36  ⇒  2k = -36 ⇒ k = -18

-5 + 10 = 5  and  -5 · 10 = -50  ⇒  2k = -50 ⇒ k = -25

-6 + 11 = 5  and  -6 · 11 = -66  ⇒  2k = -66 ⇒ k = -33

etc.

Therefore, possible values of k are:

3, 2, -3, -7, -12, -18, -25, -33 etc.

-------------------------------------------------------------------------------------------

Question (b)

Given quadratic:  [tex]9x^2+kx-5[/tex]

[tex]\implies a=9, b=k\: \textsf{and}\:c=-5[/tex]

[tex]\implies ac=9 \cdot -5=-45[/tex]

Find factors of -45:

As [tex]a+c=k[/tex]:

Therefore, all possible values of k are  -44, -12, -4, 4, 12, 44

Step-by-step explanation:

cup of sugar used for 3/4 cup of flour = 1/2

cup of sugar used for 1 cup of flour = 1/2*4/3 =2/3

Answer:

Solution 1 : 10mL with 20% acid

Solution 2 : 30mL with x% acid

Solution 3 : 40mL with 32% acid

Step-by-step explanation:

Since solution 1 + solution 2 = solution 3, let us substitute the given values we have:

10(0.2) + 30(x) = 40(0.32)

2 + 30x = 12.8

To solve for the unknown concentration x, we subtract 2 from both sides:

2 + 30x - 2 = 12.8 - 2

30x = 10.8

Dividing both sides by 30:

30x/30 = 10.8/30

x = 0.36

Therefore the unknown solution is 36% acid.

Answer:

The first option (30c + 10(0.2) = 40(0.32)

Answer:

Hi, Victoria. When you are dealing with a system of equations in three variables, you want to see first if there is anyway that you can eliminate two variables in one fell swoop. Remember that for any one given equation, you can multiply both sides by the same number without making the equation untrue. Also, remember that you can add or subtract two equations.

If we add the first and second equations, we will eliminate both the x and the y.
