Answer:
H. 2
Step-by-step explanation:
√(1 − cos² x) / sin x + √(1 − sin² x) / cos x
Use Pythagorean identity.
sin² x + cos² x = 1
So:
1 − cos² x = sin² x
and
1 − sin² x = cos² x
Substitute:
√(sin² x) / sin x + √(cos² x) / cos x
sin x / sin x + cos x / cos x
1 + 1

Answer:
Translation 1 unit left
Step-by-step explanation:
we have
f(x)=x
g(x)=(x+1)
we know that
The rule of the transformation of f(x) to g(x) is equal to
f(x) ------> g(x)
(x,y) -----> (x-1,y)
That means----> The translation is 1 unit to the left
Answer:

Step-by-step explanation:
The circumference of a circle can be found using the following formula:

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.


We also know we are using 3.14 for pi. Substitute it in for pi.

Multiply.

The circumference of the circle is 69.08 centimeters.
