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

Explanation:
With many trig problems, a diagram should help steer you in the right direction. See below. 
The red angle is the angle of depression. It's formed by starting off looking straight horizontal, then we look down 26 degrees. The blue angle adds to the red angle to get 90, so we can see that 26+64 = 90. Or you could say 90-26 = 64.
The goal is to find the value of x, which is the length from B (the lighthouse base) to point C (the ship's location).
The lighthouse is 250 ft tall, meaning AB = 250
We'll use angle BAC, or angle A for short, as the reference angle. This is the blue angle in the diagram.
We have a known adjacent side (AB = 250) and an unknown opposite side (BC = x). We use a tangent ratio to tie these sides together with the reference angle in question. This way we can solve for x.
-------------------
tan(angle) = opposite/adjacent
tan(A) = BC/AB
tan(64) = x/250
250*tan(64) = x
x = 250*tan(64)
x = 512.575960394824
x = 513
The distance from B to C is roughly 513 feet.
I'm rounding to the nearest whole number because the other values given to you are whole numbers.
 
        
             
        
        
        
Answer:
Hope this helps!!
Step-by-step explanation:
2ya and 2yb where a and b have no common factors and a and b are polynomaals
a=(x+2)(x+3)
b=(x+4)(x+5)
no common factors betwen a and b
so
2ya=2y(x+2)(x+3)=2yx²+10xy+12y
2yb=2y(x+4)(x+5)=2yx²+18xy+40y
the 2 polynomials  are  2yx²+18xy+40y and 2yx²+10xy+12y
