Answer:
BC ≈ 3.3
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan A =
, that is
tan20° =
=
( multiply both sides by 9 )
9 × tan20° = BC , then
BC ≈ 3.3 ( to the nearest tenth )
Answer:

Step-by-step explanation:
If we have that worded expression, we can convert it into actual mathematical terms.
x to the one sixth power: 
That to the power of 3:

Using exponent rules, since we have a power to a power, the powers multiply, so:

If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.
So:

Hope this helped!
Answer:
-10.2c + 2.2
Step-by-step explanation:
To make things less complicated, write down everything separate from the other. Then group together the intercepts and the coefficients into separate groups. After that, add them up separately in a format to where it will look like basic addition.
Hope this helps. I also apologize for any errors.
