The length of the longer leg of a 30-60-90 triangle is 18. What is the length of the short leg? What is the length of the
hypotenuse?

Answers

Answer 1

The length of the short leg will be 10.4. And the length of the hypotenuse will be 20.8.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The length of the longer leg of a 30-60-90 triangle is 18.

Then the length of the short leg will be

tan 30° = x / 18

          x = 10.4

Then the length of the hypotenuse will be

sin 30° = 10.4 / h

        h = 20.8

has decreased 5%. What was the total percentage decrease in the investor's stock
account? Round your answer to the nearest tenth (if necessary).

Answers

Answer:

4.5%

Step-by-step explanation:

800(1-0.01)=\color{green}{792}

800(1−0.01)=792

6180(1-0.05)=\color{blue}{5871}

\text{Find overall decrease:}

Find overall decrease:

6980(1-r)=6663

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?​

Answers

Answer:

The equation is: [tex]f(x) = 52000 - 8000x[/tex]

Step-by-step explanation:

Given

Initial = 52000

Rate = 8000 each year

Required

Determine the equation of the graph

The equation can be determined using.

[tex]Amount = Initial - Rate* Years[/tex]

We used minus (-) because, the amount reduces as the student pays.

Let

[tex]y = Amount[/tex]

[tex]x = Years[/tex]

So, we have:

[tex]y = Initial - Rate * x[/tex]

Substitute values for Initial and Rate

[tex]y = 52000 - 8000 * x[/tex]

[tex]y = 52000 - 8000x[/tex]

Express as a function:

[tex]f(x) = 52000 - 8000x[/tex]

An online fax company, EFaxIt, has a customer plan where a subscriber pays a monthly subscription fee of $6.5 dollars and can send/receive 120 fax pages at no additional cost. For each page sent or received past the 120 page limit, the customer must pay an overage fee of $0.08 per page. The following expression gives the total cost, in dollars, to send p pages beyond the plan's monthly limit.

C= 0.06p + 12.75

Required:
If the monthly bill under this plan comes out to be $16.47, what was the total number of pages that were sent or received?

Answers

Answer:

62 pages

Step-by-step explanation:

The total cost function is given as below:

C= 0.06p + 12.75

C=total cost for printing= $16.47

0.06= variable printing cost per page

p=number of pages prinited=the unknown

12.75=monthly fixed printing cost

16.47=0.06p+12.75

16.47-12.75=0.06p

3.72=0.06p

0.06p=3.72

p=3.72/0.06

p=62 pages

Step-by-step explanation:

Given

[tex]a = 40000[/tex] -- Initial population

[tex]r = 2\%[/tex] --- Rate

Required

Determine the population in 8 years

The question shows an exponential distribution and the final population will be calculated using:

[tex]y = a(1 + r)^x[/tex]

Where x is the number of years.

So, we have:

[tex]y = 40000(1 + 2\%)^8[/tex]

[tex]y = 40000(1 + 0.02)^8[/tex]

[tex]y = 40000(1.02)^8[/tex]
