Answer:
John ski down the mountain is 1285.37 feet.
Step-by-step explanation:
Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.
To find : About how far does John ski down the mountain ?
Solution :
We draw a rough image of the question for easier understanding.
Refer the attached figure below.
According to question,
Let AB be the height of mountain i.e. AB=1200 feet
The angle of depression is 21 i.e. 
We have to find how far does John ski down the mountain i.e. AC = ?
Using trigonometric,




Therefore, John ski down the mountain is 1285.37 feet.
Answer:
Circumference of circle = 87.92 centimeter
Step-by-step explanation:
In the given question;
Radius of circle = 14 centimeters
Value of π = 3.14
Find:
Circumference of circle
Computation:
⇒ Circumference of circle = 2πr
where r = Radius of circle
⇒ Circumference of circle = 2(3.14)(14)
⇒ Circumference of circle = (6.28)(14)
Circumference of circle = 87.92 centimeter

Answer:
f(y) = 4y2 - 4v
f(y) = 4y² - 4(-4) = 4y² + 16
f(y) = 4y² - 4(-3) = 4y² + 12
f(y) = 4y² - 4(-2) =4y² + 8
f(y) = 4y² - 4(-1) = 4y² + 4
