Answer 1
Answer: tan( \pi -x)=-tan(x) \n cot( \pi -x)= -cot(x) \n cot( (3 \pi )/(2) -x)=tan(x) \n \n  \n (tan( \pi -x)+cot( \pi -x)+cot( (3 \pi )/(2) -x))/(cot( \pi -x))  = (-tan(x)-cot(x)+tan(x))/(-cot(x)) = (-cot(x))/(-cot(x)) =1

What's 7/8x4/5? Cmon peeps it's hard

Answers

The fraction 7/8 x 4/5 is equivalent to 7/10 when simplified.

Given that are two fractions 7/8 and 4/5 we need to find their product.

To calculate the expression 7/8 x 4/5, you need to multiply the two fractions together.

Here's the step-by-step explanation:

Step 1: Multiply the numerators (top numbers) together:

7 x 4 = 28

Step 2: Multiply the denominators (bottom numbers) together:

8 x 5 = 40

Step 3: Write the result as a new fraction:

28/40

Step 4: Simplify the fraction (if possible) by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by the GCD:

GCD(28, 40) = 4

Divide both numerator and denominator by 4:

28 ÷ 4 = 7

40 ÷ 4 = 10

So, the final answer is 7/10.

To multiply fractions, all you have to do is multiply the numerator and then the  denominator, and then reduce and make into mixed numbers!
7x4=28
8x5=40.
28/4=7
40/4=10

Your answer to this is 7/10!!!!! I hope this helps you!!

Give the slope and y-intercept ofthe line.
slope = [?], y-intercept = [ ]
Enter the number that belongs in the green box.
Enter

Answers

Answer:

Slope = 2, y-intercept = 3

Step-by-step explanation:

I will be calculating the slope of the line using these two points: (-1, 1) and (0, 3)

Slope = (rise)/(run)

          = (3-1)/(0-(-1))

          = (3-1)/(0+1)

          = 2

Based on the graph, the y-intercept is 3.

i just did it and its D

Answers

1643 is the annual premium for the cheapest policy Jeremy can buy.

What is Annual Premium?

The amount of money a business or an individual pays for a policy annually is called the annual premium.

Face value is the amount of benefits in the form of money or other beneficiaries a policy holder receives at maturity.

Age of Jeremy = 29

Face value of the policy = $90,000

Estimated annual premium = (Face value ÷ 1000) × rate

Annual premium payable for a man whole life = (90,000 ÷ 1000) × 18.25

                                                                             = 90 × 18.25

                                                                             = 1642.5 ≅ 1643

Hence, Annual premium for the cheapest policy having a 90,000 face value that Jeremy can buy is $1643.

Casey is deciding which of two landscapers to hire. Each landscaper charges an hourly rate plus a fee for each job.Casey correctly wrote and solved a system of linear equations by substitution. In his work, he substituted an expression for one variable and solved for the other. This resulted in the equation 5 = 20. What can Casey conclude?

One landscaper charges $20 for 5 hours of work.
One landscaper’s hourly rate is $15 lower than the other landscaper’s.
Both landscapers charge the same hourly rate and the same fee per job.
Both landscapers charge the same hourly rate, but not the same fee per job.

Answers

What Casey can  conclude is D. Both landscapers charge the same hourly rate, but not the same fee per job.

What Casey can conclude based on the given scenario

Both landscapers will charge the same hourly rate because we were told they each charges an hourly rate including a fee for each job.

Their  fees per job cannot be the same  because  Casey substituted an expression for one variable while he solved for the other.

Therefore the correct option is D.

Given the preimage and image, find the dilation scale factor​

Answers

Answer:

1/2

Step-by-step explanation:

the dilation factor should be 1/2

  1. if u count the dots on the sides of the preimage there are 2 dots that's the length
  2. if u count the dots on the real image it's 4
  3. therefore 2/4 to it's lowest term is 1/2
  4. so 1/2 is the scale factor

Answer:

should be 1/2 as your answer
