Solution:
(x-2)(x-3)</span>
The answer is C. When doing this kind of equation, you basically distribute the cube to the numerator and denominator which would bring you to 1^3/4^3. You would then cube the 1 and the 4 and give you 1/64
Answer:
sin(arccos(-4/√25)) = 0.6
Step-by-step explanation:
The expression you want to evaluate is
sin(arccos(-4/√25))
= sin(arccos(-4/5))
We place this expression into a calculator and get the result
arccos(-4/5) = 2.498 rads = 143.1°
then
sin(143.1°) = 3/5
sin(143.1°) = 0.6
sin(arccos(-4/√25)) = 0.6
Answer:
about 0.974
Step-by-step explanation:
The Pythagorean theorem tells you the other leg of the right triangle is ...
cos(angle) = √(1 -sin(angle)²) = √(1 -0.051076) = √0.948924
cos(angle) ≈ 0.974127 ≈ 0.974

You can use your calculator to find the angle, then its cosine:
cos(angle) = cos(arcsin(0.226)) ≈ 0.974
You don't need to know the angle, and it doesn't matter whether it is in radians or degrees. (It is about 13.06° or 0.2280 radians.)
