So here you want to show all values greater than the parabola shown. The following parabola can be found by looking at the x intercepts. Here you have x=-3 and x=2. So your parabola can be defined as y=(x+3)(x-2) because when you make those two equal to zero you get x=-3 and x=2. And so then you go ahead and do the FOIL method for both of them when you multiply and you get

y=x²-2x+3x-6 which is

y=x²+x-6

Because the parabola is shaded above, it indicates that all the values greater than y are shaded and it’s with a solid line, therefore your answer for this inequality would be choice B. I hope this helps!!

See picture:

A hurricane was detected in the Atlantic around 5 a.m. The National Weather Service determined that it will make landfall at a location described by a vector with components [3, 7]. Around 6 a.m. on the same path, the hurricane is 1/10 the total distance from where it was detected initially to where it will make landfall.

If the hurricane is traveling on a straight path, what are the characteristics of the vector representing the path of the hurricane at 6 a.m.?

A) components: [0.30, 0.70], magnitude: 0.76
B) components: [0.30, 0.70], magnitude: 76
C) components: [30,70], magnitude: 0.76
D) components: [30,70], magnitude: 76

Answers

Answer:

The correct option is;

A) Components: [0.30, 0.70], magnitude: 0.76

Step-by-step explanation:

The given parameters are;

The path of the of the airplane at 5 a.m. given by The National Weather Service = [3, 7]

The location of the hurricane at 6 a.m. = 1/10 of the total distance between the point where it was detected to the point where it is predicted to make land fall

Therefore;

The components of the vector at 6.00 a.m. = 1/10 × [3, 7] = [0.3, 0.7]

The magnitude of the vector at 6.00 a. m. = √(0.3² + 0.7²) ≈ 0.76.

Graph -2x + y = 8 please help

Answers

Answer

Graph shown below

Step-by-step explanation:

In order to graph something, you need to know the slope and why intercept of the line. One way to do this is to put the equation into slope-intercept form. Slope intercept form is y = mx + b, where m = slope and b = your y-intercept. One way to put the equation -2x = y = 8 into the slope-intercept form is to add the -2x to the other side of the equation. Then you will get y = 8 + 2x. Now, because of the commutative property of addition, you can write the equation as y = 2x + 8. Then graph the equation. Since you know that 8 is a y intercept. You can graph the first point of your line. After, you just use slope (which is 2/1) and graph other points on a graph to get you your line. Hope this helps!

Answer:

It's C, g(x) = (1/2)^x

This is a horizontal reflection of y = 2^x

across the y axis.

Step-by-step explanation:

Using the process of elimination, you can spot this answer by applying what is logical about the transformations of an exponential function.

The transformations of a standard exponential function can be given by:

ab^(1/c(x-h))+k

First note that A must be incorrect because -2^x would be a reflection across the x axis which would not match the function g because a reflection across the x axis would cause the exponential growth or decay value b to become a reciprocal and -2 is not a reciprocal of 2.

Answer:

  [tex]\textbf{D.}\quad g(x)=\sqrt{x+6}+4[/tex]

Step-by-step explanation:

A lot of math is about matching patterns.

For example, ...

  g(x) = f(x -h) +k

means g(x) is the function f(x) translated right by h units and up by k units. This will be true for any expression of f(x).

__

In this problem, f(x) = √x. We want to translate it left 6 units (h=-6)*, and up 4 units (k=4).

The notation above means that we will replace x with (x-h) = x+6. and we will add k = 4 to the result.

  f(x) = √x

  g(x) = f(x+6) +4

  g(x) = √(x+6) +4 . . . . . . matches choice D

_____

* Left is the opposite of right, so left 6 units is the opposite of right 6 units. h=6 for right 6 units, so h=-6 for left 6 units. Then x-h = x-(-6) = x+6.

__

Comment on the graph

I find it useful to see a picture with these things. In the attached graphing calculator output, the blue curve is left 6 and up 4 from the red curve. The blue curve is g(x); the red one is f(x).

Answer:

D. A video of a drumming session

Explanation:

A presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.

Basically, any speaker who wishes to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation and using a multimedia resource.

In this scenario, Diego has written a feature story about a drumming circle. Thus, what he should include in his visual presentation to interest the audience in the drumming experience is a video of a drumming session.

Answers

9514 1404 393

Answer:

  x = -4/3y² -40/3y -103/3

  x = -4/3(y +5)² -1

Step-by-step explanation:

Solve for x.

  x = (4y² +40y +103)/(-3)

  x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US

__

Taking our clues from the graph*, we can write the vertex form equation as ...

  x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places

_____

* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...

  x = a(y -(-5))² +(-1) = a(y +5)² -1

The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.

Leading term of -20(x - 2)^15 (4-x)^11

Answers

9514 1404 393

Answer:

  20x^26

Step-by-step explanation:

The leading term is the one with the highest degree.

In the expansion of (x-2)^15, that will be x^15.

In the expansion of (4-x)^11, that will be (-x)^11 = -x^11.

So, the leading term of the product is ...

  (-20)(x^15)(-x^11) = 20x^26

__

In the attached, terms are listed in order of increasing degree, so the "leading" term appears last.

Answer:   20x^26

============================================

Work Shown:

The leading term for (x-2)^15 is x^15

The leading term for (4-x)^11 is -x^11

Multiply the outer value -20 with each of those leading terms to get

-20*x^15*(-x^11)

20x^(15+11)

20x^26

which is the leading term of -20(x - 2)^15 (4-x)^11

The correct two options are:

The maximum value of the range is 4.

The range of g(x) is {y| –1 < y ≤ 4}.

Step-by-step explanation:

The missing diagram is attached in the image below:

It is pertinent to understand that the domain is the set of all possible mathematical points where a given function is defined. In the diagram attached below, the domain relates to all possible values of x.

The range relates to all possible values of y.

From the graphical diagram;

The domain is (-4 ≤ x ≤ -1 and 0 ≤ x < 3); &

The range is  -1 < y ≤ 4.

We could see from the graph as well that, the maximum value of the range extends from -1 to 4 which indicates that the largest possible value is 4.

very fast please

Answers

Answer:

The point where all three lines meet is (8, 11)

Step-by-step explanation:

The given functions are;

f(x) = x²⁽ˣ ⁻ ⁵⁾ + 3

g(x) = 2·x - 5

h(x) = 8/x + 10

Equating the simpler functions g(x) to h(x) to find the points of the same value gives;

2·x - 5 = 8/x + 10

2·x - 15 = 8/x

2·x² - 15·x = 8

2·x² - 15·x - 8 = 0

With the aid of an online application, we have;

(2·x + 1)(x - 8) = 0

x = -1/2, or x = 8

The y-values at the point of intersection, is given as follows;

g(x) = 2·x - 5 = 2×(-1/2) - 5 = -6 or g(x) = 2·x - 5 = 2×(8) - 5 = 11

The points where g(x) and h(x) meet are (-1/2, -6) and (8, 11)

To check where the point of intersection of the two functions g(x) ang h(x) meet f(x), we have;

At x = -1/2, f(x) =  [tex]2^{(0.5 - 5)} + 3[/tex] = 3.0442

At x = -1/2, f(x) =  2⁽⁸⁻⁵⁾ + 3 = 8 + 3 = 11

Therefore, the point where all three lines meet = (8, 11).
