Sphere volume = PI * diameter^3 / / 6=
PI * 9^3 /6 =
PI * 729 / 6 =
381.70
So, answer is A
Answer:
Step-by-step explanation:
ASTC (I use a sentence to memorize: All Students Take Calculus):
Q1 - All functions are positive
Q2 - Sine is positive (Cosecant is positive as well) (all others negative)
Q3 - Tangent is positive (Cotangent is positive as well) (all others negative)
Q4 - Cosine is positive (Secant is positive as well) (all others negative)
Applying ASTC:
Secant is negative, so it can't be in quadrant 1, and quadrant 4.
Quadrant 2 - Sine and Quadrant 3 - Tangent are left.
Cosecant is positive so it can't be in quadrant 3.
Therefore, angle x is in Quadrant 2 or QII
Secant is hypotenuse / adjacent
5 = hypotenuse (hypotenuse is never a negative number)
-2 = adjacent
use pythagorean theorem to solve for opposite (bc tan = opp / adj)
tanx =
Answer:
2.44
Step-by-step explanation:
Have a good day :)
<span> Assume that the expression is..
y/3 + ¼ = 5/12
Multiply both sides by 12 to get..
4y + 3 = 5
Then...
4y = 5 - 3
4y = 2
y = 2/4
y = ½
I hope this helps! </span>
