Find the angle between the vectors A = <2,-3> asnd B = <-2, -5> to the nearest tenth of a degree.

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:

Step-by-step explanation:

12x −3y=36  ⇔ 3y = 12x - 36

                          y = 4x - 12

y = 0 ⇔ 4x - 12 = 0 ⇔ 4x = 12 ⇔ x = 12/4 = 3

So (0 ; - 12) and (3 ; 0)

Answer:

x-intercept=3,  y-intercept=-12

Step-by-step explanation:

at x-intercept y=0 such that:

12x-3(0)=36

12x=36

[tex]x=\frac{36}{12} =3[/tex]

additionally, at y-intercept x=0 such that

12(0)-3y=36

-3y=36

[tex]y= \frac{36}{-3}=-12[/tex]

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

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.

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.

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

Step-by-step explanation:

1.25+1.25+1.25+1.25=5

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.

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.
