ANSWER

KM = 17

EXPLANATION

We have that point L is on the line segment KM.

Let us draw a diagram to represent it:

From the diagram, we see that the length of KM is the sum of the lengths of KL and LM.

This means that:

KM = KL + LM

KM = 12 + 5

KM = 17

That is the value of the length of KM.

Given that the line passes through the points;

And slope;

Notice that we have 12 people evenly distributed in a round table (360°).

This way, each person would be

30° from each other.

After the two passes, the soup would have moved 120°, meaning that

It would have moved 4 places.

Now, the person sitting 4 places away from Lacy, if the soup is passed counterclockwise, is Haifa

Therefore, the soup would be in front of Haifa.

Given the system of equations;

We shall first of all re-arrange the equations in the slope-intercept form;

Note that the second one has already been expressed in the slope-intercept form. For the first one we would now have;

To plot this equations on a graph we take two extreme points. We can do this by finding the value of y when x = 0, and y when x = 0.

For the first equation, we would have;

Hence, for the first equation we have the two points;

For the second equation;

For the second equation we now have the points;

We can now input both sets of coordinates and our graph would come out as shown below.

Answer

1) Horizontal directrix.

2) Vertical directix.

3) Horizontal directix.

4) Vertical directrix.

Explanation

A parabola with a vertical axis will have a horizontal directrix.

A parabola with a horizontal axis will have a vertical directrix.

A parabola with a vertical axis will have a standard equation of the parabola as

(x - h)² = 4p (y - k),

where p ≠ 0.

The vertex of this parabola is at (h, k). The focus is at (h, k + p).

The directrix is the line y = k - p and it is a vertical directrix.

A parabola with a horizontal axis will have a standard equation of the parabola as

(y - k)² = 4p (x - h),

where p ≠ 0.

The vertex of this parabola is at (h, k). The focus is at (h + p, k).

The directrix is the line x = h - p and it is a horizontal directrix.

So, for this questions,

1.) (y - 3)² = 1/8 (x + 1)

This is of the form (y - k)² = 4p (x - h), so, we can easily see that this parabola has a horizontal directrix.

2.) (x - 2)²= 6 (y - 3)

This is of the form (x - h)² = 4p (y - k), so, we can easily see that this parabola has a vertical directrix.

3.) (y + 4)² = -12 (x + 2)

This is of the form (y - k)² = 4p (x - h), so, we can easily see that this parabola has a horizontal directrix.

4.) (x+3)²= -8(y+2)

This is of the form (x - h)² = 4p (y - k), so, we can easily see that this parabola has a vertical directrix.

Hope this Helps!!!

we are given the following expression:

First, we will subtract 17 to both sides:

We get an expression of the form:

To complete the square we will add and subtract the following term:

Replacing the values:

Therefore, we will add and subtract 36:

Now we associate the first three terms:

Now we factor in the associated terms:

Solving the operations:

Now we solve for "x", first by adding 28 to both sides:

Now we take square root to both sides:

Now we subtract 6 to both sides:

Now we factor 28 as 7*4:

Let's fill a table with the first two years, we already know those

So, we need to complete the chart for years 3,4, and 5. We know that in year 3, will receive double the money than we get in year 2, this is 2*$2=$4. Now we write that result on our table.

In year 4 we'll get double the money than in year 3, this is 2*$4=$8

Similarly, in year 5 we get double the money than what we got in year 4: 2*$8=$16

And we have filled in the table!

Now, a bonus, the pattern here seems to be an equation, notice this:

year 1 -> $1 = $2^0

year 2 ->$2 = $2^1

year 3 -> $4 = $2^2

year 4 -> $8 = $2^3

year 5 -> $16 = $2^4

This means that the amount of money we'll receive each year is given by

Where t is the year! (year 1, year 2, etc)

1) Assuming this is a right triangle, we can find the missing leg by making use of the Pythagorean Theorem.

2) Thus, we can write out this:

Note that the hypotenuse (the largest side) is always on the left side. And that this is an approximation rounded off to the nearest tenth.

3) Thus, the answer is:

we have that

the value of a represent a vertical dilation

so

We stretch the graph in the vertical direction by a scale factor of

If the value of a> 1

then

we have stretching of the graph

If the value of 0 < a < 1

then

we have a compress of the graph

The Solution:

Part (a)

Representing the problem fully in a diagram, we have:

Part (b)

We are required to find the length of QA= x.

We shall use Trigonometrical Ratio as below:

Making x the subject of the formula, we get

Thus, the distance from the control tower to point A is 80.0 meters.

Part (c)

We are required to find the length of AB= y.

Considering triangle PQB, we have:

Solving for y, we get

Thus, the distance moved by the plane from its initial position is 108.9 meters.

Given the cost of item =$ 100

If it is discounted 24%

So, the discount will be = 24% of 100 = 0.24 x 100 = $24

The cost after discount = 100 - 24 = $76

If it is marked up 24%

so, the rise will be = 24% of 76 = 0.24 x 76 = $18.24

The cost after marked up = 76 + 18.24 = $94.24

So, the answer is : No, and the cost will be = $94.24

Assuming that each snack pack has 1 juice box and 1 cheese cracker snack, then Holli can make as much as the lowest quantity of juice boxes or cheese cracker snacks.

Let the triangles represent cheese cracker snacks and squares represent juice boxes:

The smallest pack possible includes one cheese cracker snack and one juice box:

The red ovals represent snack packs. Since there are not enough cheese cracker packs to make 77 snack packs, the maximum amount of packs that can be made is 76.

From the drawing, we can see that each snack pack will have one juice box.

Given that the ratio of the sides of two smaller polygons is 4:5

To Determine: The ratio of the areas

So first we will choose two values for x and y that meet the given tip: in quadrant 2, the x - coordinate is negative and the y-coordinate is positive.​

For our case we will take x=-1 and y=1, then we can write the following two equations:

1x+3y=2 -> 1(-1)+3(1)=2 -> -1+3=2 -> 2=2

y=7x+8 -> 1=7(-1)+8 -> 1=-7+8 -> 1=1

Answer

Option C is correct.

x = -0.26 + 2pn

OR

x = -2.88 + 2pn

Explanation

Using the calculator and inverse functions

Let the unknown angle be x

Sin x = -0.26

x = Sin⁻¹ (-0.26)

x = -0.26 or -2.88 (From the calculator)

In order to generalize it, we add 2pi to both of them.

x = -0.26 + 2pn

OR

x = -2.88 + 2pn
