The correct options are;

Lines l and n are perpendicular

Lines m and n are perpendicular

Why are they known as perpendicular lines?

Two lines that meet or cross at right angles (90°) are known as perpendicular lines in geometry.

                            The word "perpendicular," which refers to a plumb line in English, comes from the Latin "perpendicularis."

Where two lines l an m are said to be perpendicular to a given line n, then we have;

1) When  l and m are in different planes,

a) l and m can be parallel lines to each other or

b) l and m can be perpendicular to each other or

c) l and m can be at an angle x, to each other

2) When l and m intersect with the line n at a point p, then, we have;

Navern's manufacturing cycle efficiency (MCE) for its elevators is: 41.4%

The formula for obtaining the manufacturing cycle efficiency is value-added time divided by the production cycle time * 100. In the data given, the process and inspection times qualify as a value-added time

Process time = 23 days

Inspection time = 13 days

Value added time = 23 + 13 = 36days

The production cycle time = Move time + process time + queue time + inspection time + wait time

= 22 + 12 + 23 + 13 + 17 days

= 87 days

So, the manufacturing efficiency time = 36/87 * 100

= 41.4%

The equivalent sine and cosine values are as follows:

The relationship between sine and cosine angles is:

sinθ = cos(90 - θ)

This equation is known as the complementary angle identity for sine and cosine. It states that the sine of an angle is equal to the cosine of its complementary angle (90 degrees minus the original angle).

For example, if we have an angle theta = 30 degrees, its complementary angle would be 90 - 30 = 60 degrees.

Answer:

? = 9.2

Step-by-step explanation:

The angle between a tangent and radius at the point of contact is 90°

Then the triangle shown is right with legs ? , 6.9 and hypotenuse = (6.9 + 4.2) = 11.5

Using Pythagoras' identity in the right triangle

?² + 6.9² = 11.5²

?² + 47.61 = 132.25 ( subtract 47.61 from both sides )

?² = 84.64 ( take the square root of both sides )

? = \(\sqrt{84.64}\) = 9.2

Answer:

Solution given:

BC=BD=6.9 units

AD=4.6units

Now

AB=4.6+6.9=11.5units.

we have

<C=90°[the line from the tangent is perpendicular to the radius of circle]

we know that ∆ABC is a right angled triangle.

hypotenuse [h]=AB=11.5units

base[b]=BC=6.9 units

perpendicular [p]=x units

By using Pythagoras law

h²=p² +b²

11.5²=x²+6.9²

x²=11.5²-6.9²

x²=84.64

x=\( \sqrt{86.64} \)=9.2

Sothe segment length indicated is 9.2 units.

The ratio of losing to the total number of possible outcomes is 99.992:100, or 12499:12500.

In the game of Lucky Lauto, the probability of winning is 0.008%, which means that the probability of losing is 100% - 0.008% = 99.992%. This is the complement of the probability of winning, as the two probabilities must add up to 100%.

The ratio of the number of ways to succeed to the total number of ways that an experiment can happen is given by the probability of success. In this case, the probability of winning is 0.008%, so the ratio of winning to the total number of possible outcomes is 0.008:100, or 1:12500.

Similarly, the ratio of losing to the total number of possible outcomes is 99.992:100, or 12499:12500.

In conclusion, the probability of losing in Lucky Lauto is 99.992%, and the ratio of losing to the total number of possible outcomes is 12499:12500.

The surface area of the triangular prism is B. 1,008 \(cm^{2}\)

Triangular Prism is a polyhedron made up of two triangular bases and three rectangular sides. It is a three-dimensional shape that has three side faces and two base faces, connected to each other through the edges.

How to determine this

The surface area of the triangular prism =  Area of the front Triangle + Area of the triangle + Each sides of the triangle by the length of the triangular prism.

Area of the front and back triangle will be the the same given the same base and height

To find the area of the triangle = 1/2 * Base * Height

Where base = 12 cm

Height = 9 cm

Area = 1/2 * 12 cm * 9 cm

Area = 6 * 9 \(cm^{2}\)

Area of the one triangle = 54 \(cm^{2}\)

So, by multiplying each sides of the triangle by the length

= Base * Length

= 12 cm * 25 cm

= 300\(cm^{2}\)

Height * Length

= 9 cm * 25 cm

= 225 \(cm^{2}\)

Then, Hypotenuse * Length

= 15 cm * 25 cm

= 375 \(cm^{2}\)

Surface area = 54\(cm^{2}\) + 54\(cm^{2}\) * 300\(cm^{2}\) + 225\(cm^{2}\) + 375\(cm^{2}\)

Surface Area = 1,008\(cm^{2}\)

Step-by-step explanation:

a. For any function, in order for a vertical stretch to happen, a must be greater than 1 so the answer to a is

a>1.

b. For b, the graph will compress when a is between 0 and 1 but not equal to both.

So the answer to. b is

0<a<1.

c.A vertical stretch happens when a>1, a horinzontal compression also happens when a>1, if you confused let me explain

Consider the graph above. Let say we have a quadratic function

\((x - 3) {}^{2} \)

Let that be the parent function, if we stretch the function, a must be greater than 1 as we established in a.

In the fist picture, let say a=2.7

The function is stretched in the vertical direction

Now, let say if we affect x.

Here, let a=2.7 we know have

The function is being compressed when a>1, so that means that

we stretched vertically or compressed horizontally when a>1. It depends on the location of a. If a is outside the parenthesis, we will stretch by a factor of a. If a is I side the parenthesis, we will compress by a factor of a.

d. A must be negative or a<0

well, the interest is going to be the increase factor on both cases, so we can simply check how much each will accumulate to in those 4 years

Let's start with the first part of the problem. There are 25 self-portraits that are planned to be sold at $2.75 each. If that's the case, how much money are they expecting to make (assuming they sell all 25 self-portraits)?

This is:

Once we have found that, now the task is to find out how they can still make that much money with three of the self-portraits now ruined, and only 21 self-portraits left.

If we need to get $68.75 to pay for the materials and we only have 21 self-portraits to sell, we could divide:

Therefore, the new minimum price we need to set for the remaining self-portraits in order to pay for the materials is $3.27 approximately.

Answer:

a = 8

b = 2

c = 48

Simplify. First, divide 3 from both sides of the ratio.

(3)/3 : (24)/3

1:8

Next, solve for b. You multiply 2 to 8 to get 16. Next, multiply 2 to 1

1 x 2 = b = 2

Finally, multiply 8 to 6 to get c.

Where the above relations are given, note that Options A,  D, and E are the relations that represents a function. The others are just relations.

To distinguish a function from a relation, look to see if any of the x values are repeated; if not, the relationship is a function. If some x values are repeated but the accompanying y values differ, we have a relation rather than a function.

Note that where you are given domain and range, only the range is represented on the x-axis.

Some of the x values may be seen repeated in B, and C.

How is this so?

B) In a coordinate system, values are represented as (x, y). so

In relations, B 2 is repeated twice to in connection with -5, and -6. That is:

(2, -5) , (2, -6)

Since two is x, then its repetition nullified the relation as a function.

C) On table indicated on C, it is much easier to identify the x and y values. As is seen, -3 is repeated twice in connection with 4 and 2. Thus, its repetition nullified the relation as a function.

As a result, Options A,  D, and E are the relations that represent a function.

We using the formula of Surface area

The surface area of a square box

S = 2(lb +lh+ bh)

S = 2(\(l^2\) + lh + lh) since l=b

S = 2(\(l^2\) + 2lh)

Also, Given that the box is open top.

S = \(l^2\) +4lh

And Surface Area of the box is 1200cm^2

1200 = \(l^2\) + 4lh ....1

Making h the subject of formula

h = (1200 - \(l^2\))/4l .....2

Volume is given as

V = \(l^2\) × h

V = \(l^2\) ×(1200 - \(l^2\))/4l

V = (1200l - \(l^3\))/4

the maximum point is at dV/dl = 0

dV/dl = (1200 - \(31^2\))/4

dV/dl = (1200 - \(31^2\))/4 = 0

Answer: 0.48 or 48%.

Explanation: The experimental probability of an event happening is calculated by dividing the number of times the event occurred by the total number of trials.

In this case, the total number of cones sold is 47 (pistachio) + 51 (other flavors) = 98

The number of cones with pistachio ice cream is 47.

So the experimental probability of the next cone sold having pistachio ice cream is 47/98 ≈ 0.48 or 48%

Therefore, the experimental probability that the next cone sold will have pistachio ice cream is about 0.48 or 48%.
