A Plane Descends 1000 Ft While Flying2.7 Mi. What Is The Angle Of Descent?

Answers

Answer 1

Answer:

4.02°

Step-by-step explanation:

The angle of descent can be obtained using trigonometry ;

Since we have a right angled triangle ;

Let's use the relation:

Sin θ = opposite / hypotenus

Hypotenus = 2.7 miles

1 mile = 5280 feets

2.7 miles = (2.7 * 5280) = 14256 feets

Sin θ = 1000 / 14256

Sin θ = 0.0701459

θ = sin^-1(0.0701459)

θ = 4.0223674

Can you please show work thank you for your time

Answers

Answer:

x= 20,1 degrees

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

So it must be

3x-11+6x-10+x = 180

added up the terms with x

10x -11-10 = 180

added up the terms without x

10x - 21 = 180

added up (21) in the two members of the equation

10x-21+21 = 180+21

10x = 201

divide the two members by 10

x = 20,1 degrees

A home value increases at a rate of 2.3% per year. If you purchased a home for 192,300, what would be the value of the home in 10 years? Round to the nearest cent.

Answers

9514 1404 393

Answer:

  $241,399.09

Step-by-step explanation:

The value is increasing exponentially with a growth factor of 1.023, so it will be ...

  v(t) = 192,300×1.023^t

  v(10) = 192,300×1.023^10 ≈ 241,399.09

The value is predicted to be $241,399.09 in 10 years.

The scale factor from 3m to 9m is ×3

So do 12 / 3 = 4

The scale factor is 4.

Since the length of one side is 9 and 3 on the other triangle, you would divide those two.

9/3=3

Then, you would decide 12 by 3 to get your final answer.

Answers

Step-by-step explanation:
