Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° =
=
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT ×
= 8
Multiply both sides by 
AT = 8
Answer:
Step-by-step explanation:
we know that
The circumference of a circle is equal to

in this problem

substitute
-----> exact value of the circumference
Find the approximate value of the circumference
assume

Here is your function:

You're looking for f(-1). To get your answer, you have to replace all the x's with -1.
Here is your new equation:

Multiply 2 by -1

<em>Remember:</em>
MULTIPLYING
- Positive(+) times negative(-) is equal to negative
- Positive(+) times positive(+) is equal to positive
- Negative(-) times negative(-) is equal to positive
- Negative(-) times positive(+) is equal to negative
DIVIDING
- Positive(+) divided by positive(+) is equal to positive
- Positive(+) divided by negative(-) is equal to negative
- Negative(-) divided by positive(+) is equal to negative
- Negative(-) divided by negative(-0 is equal to positive
Since you're multiplying a negative number by a positive number, the answer will be negative.
Here is your new equation:

Add -2 and 2:

That means your answer is 0
