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.

3) Alternate interior angles theorem

4) Definition of congruent angles

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.

Option C

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.

Step-by-step explanation:

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°

Answer:

A

Step-by-step explanation:

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.

Step-by-step explanation:

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 =

The values of the piecewise function are f(-6) = 6 and f(2) = 1

The complete question is in the attached image.

The value x = -6 is in the domain: -8 <= x < 1

The function at this domain is:

f(x) = |x|

So, we have:

f(-6) = |-6|

Evaluate

f(-6) = 6

Also, we have:

The value x = 2 is in the domain: x >= 1

The function at this domain is:

f(x) = 3

So, we have:

f(2) = 1

Hence, the values of the piecewise function are f(-6) = 6 and f(2) = 1

First function - The function is not continous on [0, 5] because h(5) is not defined.

Second function - There are no discontinuities.

In this problem we have two functions, whose continuity has to be checked. The first equation is a rational function and the second one is a polynomic function. There is a discontinuity in a function f at a given point if and only if the function evaluated at such point does not exist.

The discontinuities of rational functions are those x-values such that the denominator equals zero. The first function is defined for the interval [0, 5] and it is continuous if the function exists for all value of the interval. Thus:

5 - x = 0

x = 5

The rational function has a discontinuity at x = 5. The function is not continous on [0, 5] because h(5) is not defined. (Correct choice: C)

In accordance to algebra, polynomic functions are continuous as there exist a result for all value of x. There are no discontinuities.

Women who visit Shania's gym three times per week have the ability to drop two pounds in a month.

If women visit Shania's gym three times a week and can lose 1/2 pound per week, we can calculate how many pounds they can lose in a month (assuming a month has four weeks on average).

The rate of weight loss is 1/2 pound per week. So in one month, which is four weeks, the weight loss would be:

Weight loss per week × Number of weeks in a month = (1/2) × 4 = 2 pounds
