Answers

Answer:

J'(-4, -1)K'(-2, -5)L'(2, -5)M'(3, -1)

Step-by-step explanation:

Reflection over the line y=1 is equivalent to the transformation ...

  (x, y) ⇒ (x, 2-y)

Then the transformed coordinates are ...

  J(-4, 3) ⇒ J'(-4, -1)

  K(-2, 7) ⇒ K'(-2, -5)

  L(2, 7) ⇒ L'(2, -5)

  M(3, 3) ⇒ M'(3, -1)

_____

You can do the arithmetic (as we have done above), or you can simply read the coordinates of the reflected points from the graph.

The answer should be r=-1

Answer:

[tex]\boxed {s = -2 - 4r}[/tex]

Step-by-step explanation:

Solve for [tex]s[/tex]:

[tex]-2 = 4r + s[/tex]

-Switch sides:

[tex]-2 = 4r + s[/tex]

[tex]4r + s = -2[/tex]

-Subtract [tex]4r[/tex] to both sides:

[tex]4r - 4r + s = -2 - 4r[/tex]

If this is for a parabola, then the x-coordinate is -1, since it is directly in the middle of -5 and 3, with 4 spaces on each side (symmetry). The equation is just x = -1 since it just shows the equation of the vertical line which splits the parabola into two equal parts

I'm late but the answer to the question on the left is 21 and the answer to the question on the right is 3.

Step-by-step explanation:

Remember that you have to complete the equations in order of PEMDAS.

19-3×4÷(-6)

For this equation, you would do 3×4 first (which equals 12) then divide that by -6 (Which equals - 2) and finally you would subtract that from 19. 19 - (-2)= 21

6(-8) / -12 - 1

For this equation you would do 6(-8) first (which equals -48) then divide that by -12 (which equals 4) and finally subtract 1 from that 4. 4-1=3

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

5(x + 2) = 5x + 10

Step 2: Solve for x

Distribute 5x + 10 = 5x + 10Subtract 10 on both sides: 5x = 5xDivide both sides by 5: x = x

We see here that x is infinite amount of solutions. We can plug in any value x and it would render the equation true.

In your own words, explain the steps you would need to take to find slope from data in a table. Brainly work your magic.

Answers

Answer:

In order to find the slope, you need to find the difference in the x values and the difference in the y values. To do this, you write out y2-y1/x2-x1, insert your x and y values, and get your answer. Then, you find your y-intercept (where the x value is 0).

Answer:

Step-by-step explanation:

Start by choosing two data points. Calculate the difference between the second y value and the first y value. Then divide that by the difference between the second x value and the first x value.

A fruit company recently released a new applesauce. By the end of its first​ year, profits on this product amounted to $ 35 comma 900.$35,900. The anticipated profit for the end of the fourth year is $ 44 comma 300.$44,300. After the first​ year, the ratio of change in time to change in profit is constant. Let x be years and P be profit in dollars. A. Write a linear function​ P(x) that expresses profit as a function of time.

Answers

Answer:

P(x) = 35,900 + 2,800(x-1)

Step-by-step explanation:

P(x)

P(1) = $35,900

P(4) = $44,300

Difference in profits

P(4) - P(1)

= P(3)

= $44,300 - $35,900

= $8,400

Rate of change per year = $8,400 / 3

= $2,800 per year

The linear equation

P(x) = 35,900 + 2,800(x-1)

Where

x = number of years

Brody invested $220 in an account paying an interest rate of 3.6% compounded
annually. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 17 years?

Answers

Answer:

400

Step-by-step explanation:

Delta

The amount after 17 years is $400

How to determine the amount after 17 years?

The given parameters are:

Principal, P = $220Rate, r = 3.6%Time, t = 17 years

The interest rate is compounded annually;

So, the amount after t years is:

A = P *(1 + r)^t

This gives

A = 220 * (1 + 3.6%)^17

Evaluate

A = 401.36

To the nearest ten dollars, we have:

A = 400

Hence, the amount after 17 years is $400

You send a text to a friend. Your friend forwards it to 10 other friends, who each forward it to 10 more friends. The pattern continues for 5 rounds after your first text.

a. How many people will receive the text during the 4th round? Write your answer in scientific notation and in standard form.

b. How many total people have received the text? Write your answer in standard form. Explain your calculation.

Answers

Answer:

a. The number of people that receive the text in the fourth round are 10³ people

b. The total number of people that receive the text are 1.1111 × 10⁴ people

Step-by-step explanation:

a. The given information are;

The number of people the text is sent to in the first round = 1

In the second round, the number of people the text is sent to by people in the first round = 10

In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people

In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people

The number of people that receive the text in the fourth round = 10³ people

b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people

The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people =  11111 people = 1.1111 × 10⁴ people

a) Find the probability that a randomly selected woman will develop
breast cancer given that she has a mutation of the BRCA gene. b) Find the probability that a randomly selected woman will carry the mutation of the BRCA gene and will develop and will develop breast cancer? c) are the events of carrying this mutation and developing Brest cancer independent or dependent?​

Answers

Answer:

a) 8/10

b) [tex]0.001 \overline{33}[/tex]

c) Independent events

Step-by-step explanation:

The given information are;

The proportion of women than carries a mutation of the BRCA gene, P(A) = 1/600

The proportion of women in which the mutation develops breast cancer, P(B) = 8/10

a) The probability that a randomly selected woman will develop breast cancer given that she has a mutation of the BRCA gene is given as follows;

1 × P(B) = 1 × 8/10 = 8/10

b) The probability, P that a randomly selected woman woman will carry the mutation of the BRCA gene and will develop breast cancer is given as follows;

P(A) × P(B) = 1/600×8/10 = 1/750 = [tex]0.001 \overline{33}[/tex]

c) The events are dependent

Given that P(A) × P(B) = P(A∩B), the events of carrying the mutation and developing Breast cancer are independent events.

D) 15

Answers

Answer:

f(3) = 15. Correct: D)

Explanation:

Numeric Value of a Function

The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:

[tex]f(x)=x^2+5x-9[/tex]

It is required to find f(3), or the numeric value of f when x=3. Replace x for 3

[tex]f(3)=3^2+5(3)-9[/tex]

[tex]f(3)=9+15-9[/tex]

[tex]f(3)=15[/tex]

A) Incorrect. f(3) is not 7

B) Incorrect. f(3) is not 10

C) Incorrect. f(3) is not 9

D) Correct. f(3) =15 as found above.
