Write the equation of a line that is perpendicular to y = 5 and that passes through the point
(-7, --5).

Answer:

Step-by-step explanation:

Total number of staffs = 6400 employees

If after the holiday they will decrease their staff bye 30%, the amount of staffs decreased = 30% of 6400

= 30/100 * 6400

= 1920employees.

Amount of staffs that they will have after the holiday = Total staffs - decrement

Amount of staffs that they will have after the holiday = 6400 - 1920

= 4480employees

Step-by-step explanation:

Given the vertical line, the slope of a straight line is expressed as;

From the line, we can choose any two coordinates, using the coordinates (5, 0) and (5, 5)

x1 = 5, y1 = 0, x2 = 5 and y2 = 5

Substitute into the formula as shown;

Any value divided by zero always tends to infinity. Hence the slope of the line is undefined.

Note that the slope of any vertical line does not exist.

The probability that none of the 60 randomly selected patients left the treatment center against medical advice:

P(none left against medical advice) = (51941/52129)⁶⁰ = 0.8051091626179727

This means that there is an 80.51% chance that none of the 60 randomly selected patients left the treatment center against medical advice.

To understand this probability, we can break it down into smaller steps. First, we need to find the probability that a randomly selected patient did not leave against medical advice. This probability is equal to the number of patients who did not leave against medical advice divided by the total number of patients, which is 51941/52129 = 0.9982.

Next, we need to find the probability that 60 randomly selected patients all did not leave against medical advice. This probability can be calculated using the binomial distribution. The binomial distribution is a probability distribution that describes the probability of getting a certain number of successes in a series of independent trials. In this case, the trials are the individual patients being selected, and the success is the patient not leaving against medical advice.

The binomial distribution can be used to calculate the probability of getting 0 successes in 60 trials, which is equal to (0.9982)⁶⁰ = 0.8051091626179727.

This means that there is an 80.51% chance that none of the 60 randomly selected patients left the treatment center against medical advice.

The probability of getting chocolates with harder center is 7/15.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, there are 10 chocolates in a box. 7 of the chocolates have soft centers and 3 of the chocolates have hard centers.

Probability of choosing first chocolate with hard center is

Total number of outcomes =10

Number of favorable outcomes =7

Now, probability is 7/10

Probability of choosing second chocolate with hard center is

Total number of outcomes =9

Number of favorable outcomes =6

Now, probability is 6/9

Probability of an event = 7/10 × 6/9

= 7/10 × 2/3

= 7/5 × 1/3

= 7/15

Therefore, the probability of getting chocolates with harder center is 7/15.

To calculate 20 percent of the existing field cost, you would need to multiply the field cost by 0.20.

This will give you the amount of the cost that represents 20 percent of the total.

For example, if the existing field cost is $10,000, the calculation would be:
$10,000 x 0.20 = $2,000
20 percent of the existing field cost is $2,000.

To calculate 20 percent of the existing field cost, you can use the following expression:
Existing Field Cost x 0.20 = 20% of Existing Field Cost

The breadth of the rectangle is 6 cm.

To find the breadth, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 × (length + breadth)

Substituting the given values, we get:

18 cm = 2 × (3 cm + breadth)

Simplifying the right side of the equation, we get:

18 cm = 6 cm + 2 × breadth

Subtracting 6 cm from both sides of the equation, we get:

12 cm = 2 × breadth

Dividing both sides by 2, we get:

breadth = 6 cm

Therefore, the breadth of the rectangle is 6 cm.

Michael and Ashley bought same amount of turkey and ham.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Michael and Ashley each buy x pounds of turkey and y pounds of ham.

Michael purchased from store A.

Cost of turkey per pound at store A = $3

Cost of ham per pound at store A = $4

Michael spends $18 at store A.

3x + 4y = 18

Ashley purchased from store B.

Cost of turkey per pound at store B = $4.50

Cost of ham per pound at store B = $6

Ashley spends $27 at store B.

4.5x + 6y = 27

We get two linear equations,

3x + 4y = 18

4.5x + 6y = 27

Multiplying the first equation throughout with 4.5 and the second equation throughout with 3, we get,

13.5x + 18y = 81

13.5x + 18y = 81

Since both the equations coincide, Michael and Ashley bought same amount of Turkey and Ham.

Hence Michael and Ashley bought same amount of turkey and ham.

Step-by-step explanation:

Let x = price of 1 bag of popcorn.

Let y = price of 1 souvenir cup

First family:

4x + 5y = 50

Second family:

6x + 4y = 54

We have a system of 2 equations with 2 variables.

4x + 5y = 50

6x + 4y = 54

We are asked for the price of 1 bag of popcorn, x, so we will eliminate y and solve for x.

Multiply both sides of the first equation by -4. Multiply both sides of the second equation by 5.

-16x - 20y = -200

30x + 20y = 270

Add the equations to eliminate y.

14x = 70

x = 70/14

x = 5

Answer: $5

Answer:

$5

Step-by-step explanation:

I took the test

hypothetically, say the popcorn WAS 5 dollars. 5x4 = 20

$50 - $20 = 30 that makes the souvenirs $6 because 30/5 = 6.

If we use this for the next family, 5x6 is 30 for the popcorn plus 6x4 for the souvenirs totals at 54 making this equation correct.

Total time taken by Denise and Rachel to paint the room together us around 32.10 hours.

To determine how many hours it would take Denise and Rachel to paint the living room together:

Denise can complete the job within 55 hours, so her work rate is 1/55 of the job per hour.

Rachel can complete her job in 77 hours, so her work rate is 1/77 of the job per hour.

When they work together to paint, their work rates are also combined. Therefore, the combined work rate of Denise and Rachel is the sum of their individual work rates:

= 1/55 + 1/77

= 0.01818 + 0.01299

= 0.03117

To find the time taken by them for working together, we take the reciprocal of the combined work rate obtained:

1 / 0.03117 = 32.10 hours

Therefore, it would take Denise and Rachel approximately around 32.10 hours to paint the living room together.

Answer:

  90° clockwise

Step-by-step explanation:

Quadrants are numbered I through IV counterclockwise from upper right. Rotation from quadrant I to quadrant IV is rotation clockwise one quadrant, or 90°.

The acceleration vector can be written as a = (25/9)T + 0N, or simply a = (25)T. (option a).

To find the acceleration, we need to take the second derivative of the position vector r(t) with respect to time, which represents the rate of change of velocity. Let's start by finding the first derivative of r(t):

r'(t) = (d/dt)(9sin(5t/9) + 2)i + (d/dt)(9cos(5t/9) - 7)j + (d/dt)(12t)k

The unit tangent vector T is defined as the normalized version of the velocity vector, which is r'(t)/||r'(t)||. To find T, we calculate the magnitude of r'(t) and normalize it:

||r'(t)|| = √((25/9)²(sin²(5t/9) + cos²(5t/9))) = √((25/9)²) = 25/9

Therefore, the unit tangent vector T is given by:

T = r'(t) / ||r'(t)|| = [(25/9)(-sin(5t/9))i - (25/9)(cos(5t/9))j] / (25/9) = (-sin(5t/9))i - (cos(5t/9))j

The unit normal vector N is perpendicular to the unit tangent vector T and is given by N = (cos(5t/9))i - (-sin(5t/9))j, or simplifying it, N = (cos(5t/9))i + (sin(5t/9))j.

Now, we can express the acceleration vector in the form atT + anN by taking the dot product of r''(t) with T and N:

aT = r''(t) · T = (25/9)(-sin(5t/9))(-sin(5t/9)) + (25/9)(cos(5t/9))(-cos(5t/9)) = 25/9

aN = r''(t) · N = (25/9)(-sin(5t/9))(cos(5t/9)) + (25/9)(cos(5t/9))(sin(5t/9)) = 0

Therefore, the correct answer is: A) a = 25T
