which of the following best describes the quadratic function below ?

A. a parent function
B. an inverse function
C. opens right
D. opens down​

Answers

I thinks it’s opens right

Option A is correct, a parent function  best describes the quadratic function.

The quadratic function with a vertex at the origin and opening upward is best described as a parent function.

A parent function is the most basic form of a particular type of function.

In the case of quadratic functions, the parent function is f(x) = x².

It has a vertex at the origin (0, 0) and opens upward.

Therefore, a parent function  best describes the quadratic function.

PLEASE HELP!! Write an equation of g(x) that represents an exponential base “e” parent function with the following transformations:

Reflect over y-axis, shift right 7, vertical stretch by 12

Answers

Answer:

[tex]g(x) = 12 {e}^{ - x - 7} [/tex]

Step-by-step explanation:

The parent function is

[tex]g(x) = e {}^{x} [/tex]

First it is asked to reflect over the y axis so using the rule

[tex]g(x) = g( - x)[/tex]

Our function looks like

[tex]g(x) = e {}^{ - x} [/tex]

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

[tex]g(x) = g(x - h)[/tex]

When subtracting a 7 it looks like now

where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

[tex]g(x) = a \times g(x)[/tex]

where a is the vertical stretch. So now it would look like

[tex]g(x) = 12 {e}^{ - x - 7} [/tex]

    Remember the SAS rule is that you know the measure of 2 sides and their angle in between. (Note that SSA side side angle DOESN'T work.)  For the first question we know that sides JH and LM are congruent, and sides GJ and MK are as well. Secondly, we know that angles M and J are congruent. The question is; does this problem follow the SAS (side angle side) rule? Yes, their are two proven congruent sides on the two triangles, and the angle between them is proven congruent as well.

Second one is congruent because it follows the SSS rule (side side side) ie: all sides are congruent, so therefore the triangles are congruent.

Think about the third one. Is it congruent or not. (To be congruent it has to follow SSS, or SAS) Comment below so I can correct you.

What is Coordinate Geometry?

By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.

As per the given data:

We are given a line KL in the diagram, and we have to find out which point out of the given options will satisfy the equation of the line which is parallel to KL and passes through M.

Using the intercept form equation of line KL:

x/a + y/b = 1 [a and b are x and y intercepts respectively]

x/6 + y/4 = 1

4x + 6y = 24

Slope of this line = -a/b = -4/6 = -2/3

The line parallel to this will have the same slope and should pass through (-4, -2)

y - (-4) = (-2)/3 [x - (-2)]

y + 4 = (-2/3)[x + 2]

3y + 12 = -2x - 4

2x + 3y + 14 = 0

Clearly (8, -10) passes through this line.

2(8) + 3(-10) + 14 = 0

Hence, (8, -10) passes through this line.

Answers

Answer:

1. x = 65

2. x = 40

3. x = -7

4. x = -4

5. x = -7

6. x = 4

Step-by-step explanation:

Angles in a triangle always add up to 180 degrees.

Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.

1. 180 = 80 + 35 + x

   180 - (80 + 35) = x

   180 - 115 = x

   65 = x

2. 180 = 70 + 70 + x

   180 - (70 + 70) = x

   180 - 140 = x

   40 = x

3.  180 = 76 + 41 + (x+ 70)

    180 - (76 + 41) = x + 70

    180 - 117 = x + 70

    63 = x + 70

    63 - 70 = x

    -7 = x    

4. (the red square means its a right angle = 90 degrees)

   180 = 90 + 25 + (x + 69)

   180 - (90 + 25) = x + 69

   180 - 115 = x + 69

   65 = x + 69

   65 - 69 = x

   x = -4

5. 180 = 50 + (57 +x) + (x + 87)

   180 - 50 = (57 +x) + (x + 87)

    130 = (57 +x) + (x + 87)

  combine like terms

  130 =  144 + 2x  

  130 - 144 = 2x

  -14 = 2x

   -7 = x

6. 180 = 80 + (9x + 4) + (16x - 4)

   180 - 80 = (9x + 4) + (16x - 4)

   100 = (9x + 4) + (16x - 4)

   combine like terms

    100 = 25x + 0

    100 = 25x

    4 = x
