Y is 1/3x +5 an equation of the line that passes through point P.

The slope of the new line will be equal to (1/3) = 1/3because perpendicular lines have slopes that are the negative reciprocals of one another.

X and Y are represented by X and Y, (x,y) is the pair of coordinates for the point, and m is the slope in this equation, which reads: Y - y = m(X-x).

Y-4 = 1/3(X-1), which leads to Y = 1/3X +1 +4 and Y = 1/3X +5.

Answer:

Step-by-step explanation:

Series: 1 + 3 + 5 + 7 + 9 + ...

Proof by PMI:

P: The series starts with 1 and increases by 2 for each consecutive term.

M: The nth term of the series is 2n - 1.

I: The series is an arithmetic series with a common difference of 2.

Operations of functions:

Addition: (f + g)(x) = f(x) + g(x)

Example: f(x) = 2x + 1 and g(x) = 3x - 2, then (f + g)(x) = (2x + 1) + (3x - 2) = 5x - 1

Multiplication: (f * g)(x) = f(x) * g(x)

Example: f(x) = 2x + 1 and g(x) = 3x - 2, then (f * g)(x) = (2x + 1) * (3x - 2) = 6x^2 - 2x + 3x - 2 = 6x^2 + x - 2

The sample space consists of 8 possible outcomes, each with an equal probability of 1/8. The outcomes are the combinations of heads (h) and tails (t) when flipping 3 coins.

1. Determine how many possible outcomes there are in the sample space.

There are 8 possible outcomes in the sample space: hhh, hht, hth, htt, thh, tht, tth, and ttt.

2. Determine the likelihood of each result.

Since all outcomes have equal probability, the probability of each outcome is 1/8.

In this experiment, we are flipping three coins, and each one lands either heads (h) or tails (t). Our sample space consists of all the possible combinations of heads and tails that can occur when flipping the coins. Therefore, our sample space is {hhh, hht, hth, htt, thh, tht, tth, ttt}. Since all outcomes have equal probability, the probability of each outcome is 1/8. This means that the probability of each combination of heads and tails is the same. For example, the probability of getting 3 heads is 1/8 and the probability of getting 2 heads and 1 tail is also 1/8.

4000 donuts will Pamela need to sell in order to reach her goal.

What is the profit?

Profit is when the selling price is more than the cost price or revenue is more than the cost while loss is the opposite of profit.

To calculate the number of donuts Pamela needs to sell to reach her goal, you need to divide her desired profit by the profit per donut.

If the cost of ingredients for each donut is $0.67 and she plans to sell each donut for $2.99, the profit per donut would be $2.99 - $0.67 = $2.32.

To reach her goal of making at least 4000, she needs to make a profit of $2.32 x 4000 = $9280.

So she needs to sell $9280/$2.32 = 4000 donuts.

Hence,  4000 donuts will Pamela need to sell in order to reach her goal.

The weekly profit changes by $1000s/week.

What is profit?

The profit is defined as the amount gained by selling a product, and it should be more than the cost price of the product. In other words, the profit is a gain obtained from any business activities.

To find the increase in weekly revenue, we need to find the difference in revenue at the two output levels:

2500 units/week: Revenue = 100(2500) + 43 = 2543

2000 units/week: Revenue = 100(2000) + 43 = 2043

So the increase in weekly revenue is 2543 - 2043 = $500s/week.

To find the change in weekly profit, we need to subtract the change in cost from the change in revenue:

Change in cost: 2500 units/week - 2000 units/week = 500 units/week * 3 $1000s/week/unit = 1500 $1000s/week

Change in profit: $500s/week - $1500s/week = -1000

Hence, the weekly profit changes by $1000s/week.

Answer: The quotient of 2 and 9 is 0.2222 (approximately) or 2/9

Step-by-step explanation:

Quotient is a mathematical term that refers to the result of dividing one number by another. In this case, the quotient of 2 and 9 is found by dividing 2 by 9, which results in 0.2222 (approximately) or 2/9.

It's important to note that the quotient is a decimal number because 9 doesn't divide into 2 exactly, so there is a remainder of 0.2222. The quotient represents the number of times 9 can be divided into 2, which is a fraction of a time. In this case, 9 can be divided into 2 only 0.2222 times.

I hope this helps :)

The quotient of 2 and 9 is the result of the division of 2 by 9 which is approximately 0.2222.

The question is asking for the quotient of 2 and 9. The quotient is the result of division. So, to find the quotient of 2 and 9, you need to divide two by nine.

The calculation is as follows: 2 ÷ 9 = 0.2222 (rounded to the fourth decimal place).

So, the quotient of 2 and 9 is approximately 0.2222.

Always remember, that when the divider (the number we divide by) is larger than the dividend (the number to be divided), we get a quotient less than one.

Answer:

Step-by-step explanation:

-4(x-2)=2-2x

-4x+8=2-2x

-4x+8=-2x+2

-4x=-2x+2-8

-4x=2x-6

-2x=-6

x=3

Let's solve your equation step-by-step.

-4(x-2)=2-2x

Step 1: Simplify both sides of the

equation.

-4(x-2)=2-2x

Simplify:

(-4)(x)+(-4)(-2) = 2+ -2x

(Distribute)

-4x+8=2+ -2x

-4x+8=-2x+2

Step 2: Add 2x to both sides.

-4x+8 + 2x = -2x+2+2x

-2x+8=2

Step 3: Subtract 8 from both sides.

-2x+8-82-8

-2x=-6

Step 4: Divide both sides by -2.

-2x -6 = -2 -2

A semi-annual coupon bond is a bond that pays interest twice a year at a fixed rate.

To determine the amount of semi-annual coupon paid, you can use the following formula:

C = (r * FV) / n

Where:

C = coupon payment (semi-annual)

r = annual coupon rate (3% in this case)

FV = face value (100,000 in this case)

n = number of coupon payments per year (2 for semi-annual)

So, the semi-annual coupon payment for the bond is:

C = (0.03 * 100,000) / 2

C = 1500

The bond matures after 8 years, so the bond will pay 8*2 = 16 semi-annual coupons.

To find the value of ( f ∘ g ) (4), we need to first substitute 4 into the definition of g(x) and then substitute the result into the definition of f(x).

First we substitute 4 into g(x):

g(4) = -2(4) + 15 = -8 + 15 = 7

Now we substitute 7 into f(x):

f(g(4)) = f(7) = 7^2 - 5(7) - 2 = 49 - 35 - 2 = 12

So the value of ( f ∘ g ) (4) is 12.

The probability of rolling two trick number cubes with the numbers 5, 10, and 15 on them can be calculated using the formula P(A) = n(A) / n(S), where P(A) is the probability of event A, n(A) is the number of favorable outcomes, and n(S) is the total number of possible outcomes.

In this case, the total number of possible outcomes is 6, since there are six possible combinations of two number cubes. The number of favorable outcomes for a sum of 10 is 2, since there are two possible combinations (5 and 5, and 10 and 15). Therefore, the probability of rolling a sum of 10 is 2/6, or one-third. The probability of rolling a sum of 15 is also one-third, since there is only one possible combination (10 and 5). The probability of rolling a sum of 20 is one-sixth, since there is only one possible combination (10 and 10). Therefore, the probability model for the sum of the two number cubes is a 2-column table with 3 rows. Column 1 is labeled Sum with entries 5, 10, 15. Column 2 is labeled probability with entries one-half, one-third, one-sixth.
