Explain a scenario where using properties of tangent lines to solve problems could be used in real life.

Answers

Answer 1

Answer:If we are traveling in a car around a corner and we drive over something slippery on the road (like oil, ice, water or loose gravel) and our car starts to skid, it will continue in a direction tangent to the curve.

Step-by-step explanation:

Answer 2

Tangent lines are essential in real-life scenarios like physics for analyzing motion, such as object velocity and acceleration, enabling accurate predictions in various fields.

**Tangent lines** are crucial in various real-life scenarios. For instance, in **physics**, when analyzing the motion of an object along a curved path, the tangent line at a specific point helps determine the object's instantaneous velocity or acceleration. This is vital in understanding how objects move in the real world.

A practical example is when studying the trajectory of a ball thrown into the air. By using the **tangent line** at different points of its path, we can calculate the ball's velocity or acceleration at those instances, assisting in sports analytics, engineering designs, or even space exploration calculations.

Understanding **tangent lines** is essential in fields like **engineering** and **physics** as it allows for precise calculations and predictions based on the behavior of curved functions and their instantaneous rates of change.

What is the measure, in degrees, of the supplement of an angle measuring $50$ degrees? I will vote Brainliest first correct answer!!

Answers

Supplement of an angle measuring 50 degrees is 130 degrees

Step-by-step explanation:

Step 1 :

Given,

Measure of the angle = 50 °

We need to calculate the supplement of this angle

Step 2 :

2 angles are supplement to each other if the sum of their measures is 180°.

Hence the supplement of one angle can be computed by subtracting the value of that angle from 180°

Hence the supplementary angle to 50 ° is 180° - 50 ° = 130 °

Step 3:

We can't answer the first question, because we know nothing about the spinner (looks like some information is missing).

As for the second question, the coordinates of the midpoint are simply the average of the coordinates of the endpoint, so if we let [tex]M[/tex] be the midpoint of [tex]A[/tex] and [tex]B[/tex], we have

[tex]M=\left(\dfrac{A_x+B_x}{2},\dfrac{A_y+B_y}{2}\right)[/tex]

B:x-3/20 = 12/x+3
C:x-3/12 = x+3/20
D:x-3/12 = 20/x+3

Answers

The reciprocal property is:

[tex]\frac{x - 3}{12} = \frac{x + 3}{20}[/tex]

Solution:

Given that,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

The reciprocal property is given as:

The reciprocal of a fraction is the numerator and denominator switched

[tex]\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}[/tex]

Therefore,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

320 cubic inches

128 cubic inches

448 cubic inches

Step-by-step explanation:

Step 1:

Given,

Dimensions of the first rectangular prism = l * b * h = 16*5*4

[length is 16 as the total length is 20 and the width of the 2nd prism till the dotted line is 4]

Dimensions of the second rectangular prism = l * b * h = 4*4*8

We need to determine  volume of the 2 prisms and the whole figure. The volume of  rectangular prism can be obtained by multiplying the length breadth and the height.

Step 2:

Volume of the first prism = l * b * h = 16*5*4 = 320 cubic inches

Volume of the first prism = l * b * h = 4*4*8 = 128 cubic inches

The volume of the whole figure is the sum of the 2 rectangular prisms = 320 + 128 = 448 cubic inches

Emanuel is planting trees along a new city sidewalk. He plants the same number of trees on each city block. After 3 blocks, he has planted 15 trees. After 5 blocks, he has planted 25 trees. At what rate is Emanuel planting trees?

Answers

Answer:

Every 1 Block he is planting 5 tree's.

Step-by-step explanation:

There are multiple ways you can do it but the easiest I prefer is just to divided The Tree's by the Blocks.

Ex: 6 Blocks is 30 trees, Divide 30 by 6 and you get 5 for every block.

Final answer:

Emanuel is planting trees at a rate of 5 trees per block. This is determined by dividing the total number of trees by the total number of blocks planted.

Explanation:

Emanuel is planting trees at a consistent rate. To find this rate, we can set up a simple ratio.

He planted 15 trees in 3 blocks, which simplifies to 5 trees per block. This can be confirmed by looking at the second part of the problem. After 5 blocks, he had planted 25 trees. If we divide the total number of trees by the total number of blocks (25 trees / 5 blocks), we also get 5 trees per block.

Therefore, the rate at which Emanuel is planting trees is 5 trees per block.

The domain of this function is {-12, -6, 3, 15}.

At x = –6, y = 11

At x = 15, y = –3

At x = –12, y = 15

Solution:

The function is [tex]y=-\frac{2}{3} x+7[/tex].

The domain of the function is {–12, –6, 3, 15}.

Substitute x = –6 in the function to find y.

[tex]$y=-\frac{2}{3} (-6)+7[/tex]

y = 4 + 7

y = 11

Substitute y = 5 in the function to find x.

[tex]$5=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$-2=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = 3

Substitute x = 15 in the function to find y.

[tex]$y=-\frac{2}{3} (15)+7[/tex]

y = –10 + 7

y = –3

Substitute y = 15 in the function to find x.

[tex]$15=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$8=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = –12

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15

Answer: About 4 movies

Step-by-step explanation:

1 2/3 times 4/1 = 28/5

28/5 converted to a mixed number is 5 3/5

so therefore it would be ABOUT 4 movies

Final answer:

To find the number of movies that can be downloaded, divide the total downloading time by the time it takes to download one movie. In this case, 15 movies can be downloaded.

Explanation:

To find the number of movies that can be downloaded, we need to divide the total downloading time by the time it takes to download one movie. First, convert the mixed number 5 1/4 to an improper fraction, which is 21/4. Then, multiply 21/4 by the reciprocal of 1 2/5, which is 5/7. This gives us a total of 15 movies that can be downloaded.

What is the probability that 13 people have different birthdays

Answers

Answer: Your answer for 13 people should be somewhere in the 20% range. Letting n=13 and we have about a 80.56% probability that no two out of the 13 share a birthday. As stated, the complement of this is the probability that at least two of the 13 share a birthday.

Step-by-step explanation:

Final answer:

The probability that 13 people have different birthdays is calculated by multiplying the individual probabilities for each person, considering each additional person has one less available day to have a unique birthday, resulting in an overall probability of approximately 83.3%.

Explanation:

The question asks what the probability is that 13 people have different birthdays, assuming we can neglect the impact of leap years. To solve this, we consider that there are 365 days in a year for a birthday to occur. The first person can have their birthday on any day, so the probability is 365/365. For the second person to have a different birthday, there are 364 possible days left, so the probability is 364/365. This pattern continues down for all 13 people.

For the 1st person: 365/365For the 2nd person: 364/365For the 3rd person: 363/365And so on until the 13th person.

To find the overall probability, we multiply these probabilities together:

Overall probability = (365/365) * (364/365) * (363/365) * ... * (353/365) = 0.833, or 83.3% when rounded to one decimal place.

This calculation is a practical application of probability theory, demonstrating how the likelihood of events changes as conditions evolve, such as when considering the probability of shared birthdays among a group of people.
