Find the point on the line 3x + y +4= 0 which is closest to the point (-3,2). Answer: M Note: Your answer should be a point in form ( 2-coordinate, y-coordinate)

Answer:

39

Step-by-step explanation:

Complementary angles add up to 90.

(6x - 15) + (3x + 6) = 90

9x - 9 = 90

9x = 99

x = 99/9 = 11

m∠2 = 3(11) + 6 = 39

Answer:

-2

Step-by-step explanation:

slope = y2 - y1  / x2 - x1

= 9 - (-3)  /   -2 -4

= 12 / -6

= -2

There are total 35 students in the class.

Given that,

Vikas ranks 9th in the class,

Assume that there are 'n' number of students in the class  

Therefore,

There are 8 students who have scored better than him.

So, The total number of students with a rank better or equal to Vikas,

= 8 + 1 (Vikas himself)

= 9.

Now, his friend got the 35th rank which is the last rank

This means that there are a total of 35 students in the class.

Also, also given that,

Vikas's rank from the last is 27th,

This means that there are 26 students who have scored lower than Vikas.

So, the total number of students with a rank worse or equal to Vikas,

= 26 + 1 (Vikas himself)

 = 27.

Therefore, The total number of students in the class = 35.

Answer: g 26

Step-by-step explanation: 100-48= 52

52/2=26

The linear equation in the given graph is.

y = 40x

We know that the general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept, these two values are constants, and the variables are x and y.

First, notice that the line intercepts the y-axis at the point (0, 0), then b = 0.

So we can write:

y = a*x

Also notice that the line passes through the point (1, 40), then:

40 = a*1

40/1 = a

The linear equation is.

y = 40x

Answer: 2A/b = h

Step-by-step explanation: First, get rid of the fraction by multiplying both sides of the equation by 2. That gives us 2A = bh.

Don't be thrown off by the capital A in this problem.

Just treat it like any other variable.

To get h by itself on the right side of the equation, we now simply

divide both sides of the equation by b and our answer is 2A/b = h.

Take a look back at the formula now in the

original problem, A = 1/2bh, does that look familiar?

Answer:

\(a ^{2} \)

a^4 + a^2 + 1

a^4 + a^2 + x + 1

a^2 ( a^2 + 1) + 1 ( x + 1)

so, here clearly we can see that If wee add a^2 in place of x it would be a perfect square..

The crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Specific gravity at 60 °F: 0.88

API° at 60 °F: 28

Watson characterization factor: 1.014

Refractive index: 1.44

Surface tension: 20 dyne/cm

Paraffinic, naphthenic, or aromatic: Paraffinic

Specific gravity at 60 °F the specific gravity of a liquid is its density relative to the density of water. The specific gravity of crude oil is typically between 0.8 and 1.0. A specific gravity of 0.88 means that the crude oil is 88% as dense as water.

API° at 60 °F: The API°, or American Petroleum Institute gravity, is a measure of the lightness or darkness of crude oil. A higher API° indicates a lighter crude oil. A crude oil with an API° of 28 is considered to be a medium-heavy crude oil.

Watson characterization factor the Watson characterization factor is a measure of the aromaticity of crude oil. A higher Watson characterization factor indicates a more aromatic crude oil. A crude oil with a Watson characterization factor of 1.014 is considered to be a paraffinic crude oil.

Refractive index the refractive index of a liquid is a measure of how much light is bent when it passes through the liquid. The refractive index of crude oil is typically between 1.4 and 1.5. A refractive index of 1.44 indicates that the crude oil is slightly more refractive than water.

Surface tension the surface tension of a liquid is a measure of the force that acts at the surface of the liquid, tending to minimize the surface area. The surface tension of crude oil is typically between 20 and 30 dyne/cm. A surface tension of 20 dyne/cm indicates that the crude oil has a relatively high surface tension.

Based on the estimated values, the crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Answer:

-0.5

Step-by-step explanation:

Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.

The odd rolls are 1, 3 and 5. The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.

The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.

The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.

Rolling any even number gives us the same value. The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.

Together we have

1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5

"The customer yields $780 per year in profits for this retailer."

Customer lifetime value (CLV) is a prediction of the total value a customer will bring to a business over their entire relationship with the company. Retailer profits refer to the financial gain a retailer makes after subtracting all costs, including the cost of goods sold, operating expenses, and taxes, from the revenue generated by their retail sales.

The customer spends $250 a week, so the retailer profits:

If the shopper visits the store every week for a year, the retailer profits:

If this shopper remains loyal for a 10-year lifespan, the retailer profits:

This is the CLV  without considering inflation or any other factors. To consider inflation, we can apply the 8% annual interest rate to calculate the present value of the future profits. The present value of $7,800 over 10 years with an 8% interest rate is approximately $5,100 (the exact value will depend on the method used to calculate the present value).

This question should be provided as:

Assume that a customer shops at a local grocery store spending an average of ​$250 a​ week, resulting in a retailer profit of ​$15 each week from this customer. Assuming the shopper visits the store all 52 weeks of the​ year, calculate the customer lifetime value if this shopper remains loyal over a​ 10-year life span.

Step-by-step explanation:

1 piece per week can be written as a 1:1 ratio

The package weighs approximately 10.9 pounds.

Let's assume the weight of the package in pounds is "x". We can break down the cost of sending the package by media mail into three parts:

1. The cost for the first pound: $2.41.

2. The cost for the additional pounds up to six pounds: $0.41 per pound.

3. The cost for the additional pounds beyond six pounds: $0.39 per pound.

To determine the weight of the package, we need to solve the equation based on the given information:

Cost = $2.41 + $0.41 * (x - 1) + $0.39 * (x - 7)

We know that the cost of sending the package is $7.99, so we can set up the equation as follows:

$7.99 = $2.41 + $0.41 * (x - 1) + $0.39 * (x - 7)

Now, we can solve this equation to find the value of "x," which represents the weight of the package.

$7.99 - $2.41 = $0.41 * (x - 1) + $0.39 * (x - 7)

$5.58 = $0.41x - $0.41 + $0.39x - $2.73

$5.58 = $0.8x - $3.14

$0.8x = $8.72

x ≈ 10.9

Therefore, there are around 10.9 pounds in the bundle.

The mistake the arrangers made is in the second inequality. They considered the number of caps to be bought should be at least 5 times greater than the number of blouses, not the other way around. The correct inequality should be C

The correct answer is D) The first inequality should be s + h ≤ 1800.

The organizers made an error in the first inequality. The given inequality 10s + 8h ≤ 1800 represents the total cost of buying shirts (10s) and hats (8h) should be less than or equal to $1800. However, this does not take into account the fact that the organizers want to buy at least 5 times as many shirts as hats, as indicated by the second inequality h ≥ 5s.

The correct way to represent this constraint is by using the equation s + h ≤ 1800, which ensures that the total number of shirts and hats purchased does not exceed $1800 in cost. This is because the organizers want to make sure that the total cost of shirts and hats combined does not exceed the budget of $1800.

m = 28

Step-by-step explanation:

Simplifying

0.1(0.5m + 6) = 2

Reorder the terms:

0.1(6 + 0.5m) = 2

(6 * 0.1 + 0.5m * 0.1) = 2

(0.6 + 0.05m) = 2

Solving

0.6 + 0.05m = 2

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-0.6' to each side of the equation.

0.6 + -0.6 + 0.05m = 2 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0

0.0 + 0.05m = 2 + -0.6

0.05m = 2 + -0.6

Combine like terms: 2 + -0.6 = 1.4

0.05m = 1.4

Divide each side by '0.05'.

m = 28
