Answer:

Domain: All Real Numbers

Step-by-step explanation:

Since this function is a linear function, it will use any x-value in order to continue with being a linear function. Therefore, if the line goes on for infinity, every x-value will be used for infinity. Therefore, the domain will be All Real Numbers since every number on the x-axis has a possibility of being used.

C. 180°

Step-by-step explanation:

The degree measure of the arc of a full circle is 360°

A diameter divides a circle into two parts of equal size, so the degree measure of each part is half of the degree measure of a full circle.

360°/2 = 180°

I assume this should look like

V(x) = -x² + 2x - 4

W(x) = -x³ + 2x² + x + 5

when doing arithmetic operations with whole functions, we simply do these operations with the whole expressions :

V(x) × W(x) =

(-x² + 2x - 4) × (-x³ + 2x² + x + 5) =

= x⁵ - 2x⁴ - x³ - 5x² - 2x⁴ + 4x³ + 2x² + 10x + 4x³ - 8x² - 4x - 20 =

= x⁵ - 4x⁴ + 7x³ - 11x² + 6x - 20

Answer:

I think A

Step-by-step explanation:

The complete equation is x^2 - 4x + (-2) = (-2)^2

The equation is given as:

x^2 - 4x + __ = (__)^2

_____________________________

Take the coefficient of x

k = -4

Divide by 2

k/2 = -4/2

k/2 = -2

Square both sides

(k/2)^2 = (-2)^2

_____________________________

Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2

So, we have:

x^2 - 4x + (-2) = (-2)^2

Hence, the complete equation is x^2 - 4x + (-2) = (-2)^2

28=2x2x7

42=2x3x7

60=2x2x3x5

LCM=2x2x3x5x7x2x2=1680

Answer:

First option

Explanation:

The inverse of a graph is its reflection on the line y = x.

This means that it is the graph that you get by reflecting the original graph on a line with the equation y = x.

In the picture below, we can see a function (red graph), its inverse (blue graph) and the line (green) that the two graphs are reflected on.

From the picture below, we can see that the shapes of the graph of a function and its inverse is similar and correspond to the shape given as the first option in the question. Therefore, the first option is the answer.

Answer:

  2 units

Step-by-step explanation:

The given equation graphs as a parabola that opens to the right. It can be written in the form ...

  (4p)x = ay² +by +c

When the equation is written in the form ...

  (4p)x = ay² +by +c

The value of p is the focus-to-vertex distance. The length of the latus rectum (focal chord) is 4 times the value of p, so is the coefficient of x in the equation.

Rewriting the given equation to the form shown above, we have ...

  2x = y² +6y +13

That is, the value of 4p, the coefficient of x, is 2. The length of the focal chord is 2 units.

Using a linear function, it is found that the product rs is rs = 81.

A linear function is modeled by:

y = mx + b

In which:

In this problem, when x changes by 68(from -64 to 68), y changes by -16(from 12 to -4), hence the slope is given by:

m = -16/64 = -0.25.

Hence:

y = -0.25x + b.

When x = 34, y = -4, hence this is used to find b.

-4 = -0.25(34) + b

b = 4.5.

Hence the function is:

y = -0.25x + 4.5.

f(r) = 0, hence:

-0.25x + 4.5 = 0

x = 4.5/0.25

x = 18

r = 18.

f (0) = s, hence s = 4.5.

Then the value of the product is:

rs = 18 x 4.5 = 81.

If m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.

Supplementary angles are the angles whose sum is equal to 180°. The angles formed when one straight line intersects the other, on the point of intersection on the same side of any line are always supplementary.

In the given question, AB and DE are two straight lines intersecting at point C. ∠ACD and ∠ACE lie on the same side of the line DE, thus they are supplementary angles.

Therefore, m ∠ACD + m ∠ACE = 180°.

But we know that m ∠ACD = 100°. So,

m ∠ACD + m ∠ACE = 180°,

or, 100° + m ∠ACE = 180°,

or, m ∠ACE = 180° - 100° = 80°.

Therefore, if m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.
