The coordinates of point M are approximately (5.7, 2.2).

What are coordinates?

Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.

To find the coordinates of point M, we need to first find the coordinates of point L.

Since point L partitions the directed line segment from K to N in a ratio of 1:2, we can use the midpoint formula to find its coordinates:

L = [(1/3)(8 - 6) + (-6), (1/3)(3 - (-2)) + (-2)]

L = (-4, 1)

Next, we need to find the coordinates of point M, which partitions the directed line segment from L to N in a ratio of 3:1. We can use the same formula:

M = [(3/4)(8) + (1/4)(-4), (3/4)(3) + (1/4)(1)]

M = (5.5, 2)

Rounding to the nearest tenth, we get M ≈ (5.7, 2.2).

Therefore, the coordinates of point M are approximately (5.7, 2.2).

b. 29i-20

c. -21i

d. 29

Answers

Answer:

Answer:

The value of the (2 – 5i)(p + q)i is 29i .

Option (a) is correct .

Step-by-step explanation:

As the expression given in the question.

= (2 - 5i) (p + q)i

Simplify the above

= (2 - 5i) (pi + qi)

= 2pi + 2qi - 5pi²- 5qi²

As i² = -1

Put in the above

= 2pi + 2qi + 5p +5q

= 2i × 2 + 2i × 5i + 5 × 2 + 5 × 5i

= 4i + 10i² + 10 + 25i

As i² = -1

= 4i - 10 + 10 + 25i

= 29i

Thus the value of the (2 – 5i)(p + q)i is 29i .

Henry made 3 batches of cookies. Each batch creates 12 cookies. If Henry gave the same amount of cookies to all of his 20 coworkers, how many cookies will Henry have left?

Answers

he makes 3 batches of cookies...each batch contains 12 cookies...
so there are (3 * 12) = 36 cookies.
He wants to give the same amount of cookies to all of his 20 coworkers...

he can give each coworker 1 cookie and have 16 remaining cookies <=
3 batch of cookies and 12 cookies in each batch

12*3=36

So Henry has a total of 36 cookies he can give to his 20 coworkers

Subtract 36-20=16

Henry will have 16 cookies left over

Rewrite the expression in terms of ln 5 and ln 6. ln(4500)

Answers

Final answer:

The expression ln(4500) can be rewritten in terms of ln 5 and ln 6 by using the properties of logarithms and prime factorization. The final expression is ln(4500) = 3 * ln(5) + 5 * ln(6).

Explanation:

To rewrite the expression ln(4500) in terms of ln 5 and ln 6, we first need to break down 4500 into its prime factors. Starting off, we know 4500 = 5 * 5 * 5 * 3 * 2 * 2 * 2 * 2 * 2. Applying the properties of logarithms, ln a * b = ln a + ln b, the expression then becomes:

ln(4500) = 3* ln(5) + ln(3) + 5* ln(2).

Now, we have ln3 and ln2 terms instead of the desired ln5 and ln6 terms. To convert ln(2) and ln(3) to ln(5) and ln(6), we note that 6 = 2 * 3. Thus, ln(6) = ln(2) + ln(3). Replacing ln2 and ln3 with ln6 in our expression gives:

ln(4500) = 3 * ln(5) + 5 * ln(6).

So, ln(4500) can be expressed in terms of ln5 and ln6 as 3 * ln(5) + 5 * ln(6).

find the angle whose cosine is .4203

Answers

The cosine of 1.137020412 degrees is 0.4204.

The angle is approximately 65.09 degrees or 1.106 radians.

To find the angle whose cosine is 0.4203, we can use the inverse cosine function, denoted as [tex]cos^{-1}[/tex]or arccos.

Ensure your calculator is in degree mode.Input 0.4203 into your calculator.Use the arccos function to find the angle.

The result will be:

[tex]cos^{-1}[/tex](0.4203) ≈ 65.09°

This means the angle whose cosine is 0.4203 is approximately 65.09 degrees or 1.106 radians.

Delia relative long jump length was recorded as 0. What does this mean

Answers

When we say about an object relative to something, this only means that we are comparing an object’s characteristic to that of our reference. So in this case, I think we are referencing Delia’s jump to someone else. Say our reference has a long jump length of 5 meters, since Delia’s relative long jump length is 0, this means that relative to the reference there is no difference. Therefore, Delia’s jump length is also 5 meters.

Complete the coordinate proof of the theorem.

Answers

C(a,b), because the x-coordinate( first coordinate) is a (seeing as it is situated directly above point B, which also has an x-coordinate of a) and the y-coordinate ( second coordinate) is b (seeing as it is situated on the same horizontal level as point D, which also has a y-coordinate of b)

the length of AC can be calculated with the theorem of Pythagoras:

length AB = a - 0 = a
length BC = b - 0 = b

seeing as the length of AC is the longest, it can be calculated by the following formula:

It is called "Pythagoras' Theorem" and can be written in one short equation:

a^2 + b^2 = c^2 (^ means to the power of by the way)

in this case, A and B are lengths AB and BC, so lenght AC can be calculated as the following:

a^2 + b^2 = (length AC)^2
length AC = √(a^2 + b^2)

Extra information: Seeing as the shape of the drawn lines is a rectangle, lines AC and BD have to be the same length, so BD is also √(a^2 + b^2). But that is also stated in the assignment!

Alice is on the line x = 4, and she is √40 away from (2,3). What is the sum of the possible y-coordinates of the point Alice is at?

Answers

To answer this question, we will use the rule of the distance between two points which is stated as follows:
d^2 = (x1-x2)^2 + (y1-y2)^2

The givens are:
d = sqrt(40) .............> d^2 = 40
point 1 is (4,y1) 
point 2 is (2,3)
Therefore,
x1 = 4
x2 = 2
y1 = y1
y2 = 3

Substitute with the givens in the above equation:
40 = (4-2)^2 + (y1-3)^2
40 = 4 + y1^2 - 6y1 + 9
y1^2 - 6y1 + 9 + 4 - 40 = 0
y1^2 - 6y1 -27 = 0
(y1-9)(y1+3) = 0
either: y1 = 9
or: y1 = -3

do Dollar markdowns represent price increases to the original selling price.

Answers

No, dollar markdowns do not represent price increases to the original selling price.

In retail, a markdown refers to a reduction in the price of an item from its original selling price. When a dollar markdown occurs, it means that the price of the item has been decreased by a specific dollar amount. This reduction is typically implemented to stimulate sales, clear out excess inventory, or attract customers.

For example, if an item originally priced at $50 is marked down by $10, the new selling price would be $40. Therefore, dollar markdowns signify a decrease in the selling price relative to the original price, rather than an increase. They are a common strategy used by retailers to adjust pricing to match market demand and drive sales.

Supposed two angles are supplementary and one of them measures 31 degree what is The measure of the other angle

Answers

Supplementary angles always, without exception, add up to 180°. If two angles add up to 180° and one of them is 31° , then simply take 180 and subtract 31 from that. That would be 149°.

We will see that if the angles are supplementary, the measure of the other angle is 149°.

How to get the measure of the other angle?

Two angles A and B are supplementary if their measures add up to 180°, so we must have:

A + B = 180°

In this case, we know that one of the angles measures 31°, let's say:

A = 31°

Replacing that we get:

31° + B = 180°

Solving for B, we get:

B = 180° - 31° = 149°

We conclude that the measure of the other angle is 149°.
