Answer:
A
Step-by-step explanation:
sin 30 = y/7
Sin is being used and there is only one option with sin in it, so that is the right one.
Answer: 30.06
Step-by-step explanation: just multiply or type it into a calculator
Use the Product Rule: x^ax^b = x^a + b
6x^3 + 1y^2 + 6
Simplify 3 + 1 to 4
6x^4y^2 + 6
Simplify 2 + 6 to 8
<u>= C) 6x^4 y^8</u>
Answer: 352/105
Step-by-step explanation:
Diameter of the circular disk is
(2−x2)−x2
so that the radius of the disk is the diameter divide by 2
(2−x2−x2)/2.
Integrating V at 1 and -1, we get
V =Z 1−1A dx =Z 1−1π(1 − x2)2
dx = π(x −2/3x3 +1/5x5)1−1
=16/15π
= 352/105
