Answer:
2 pi, -2 pi, pi, -pi
Step-by-step explanation:
Draw a unit circle and label the 4 points where it intersects the x/y axis. for example at 0 degrees or 360/-360 degrees the (x,y) or (cosine theta, sine theta) value is (1,0).
Answer:
<em>B.) Kelly got the better deal.</em>
Step-by-step explanation:
FORMULA:
- Volume of cylinder = πr²h
- Volume of sphere = 4/3πr³
ANSWER:
Volume of capsule = 4/3πr³ + πr²h
πr²(4/3r + h)
- 3.14 × 2²(8/3 + 5.6)
- 3.14 × 4(2.6 + 5.6)
- 12.56(8.2)
- 102.99 or 103 rounded.
Now, Density = 0.7mg/mm³
You would have to use this equation : y2-y1/x2-x1 = slope
So it would be -13 +3/6-2= -10/4
Simplify it and you get : -5/2
Slope is -5/2
Using linear combination method, the solution to given system of equations are (-7, -15)
<h3><u>Solution:</u></h3>
Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated
Addition is used when the two equations have terms that are exact opposites, and subtraction is used when the two equations have terms that are the same.
<u><em>Given system of equations are:</em></u>
2x - y = 1 ---- eqn 1
3x - y = -6 ------ eqn 2
Subtract eqn 2 from eqn 1
2x - y = 1
3x - y = -6
(-) -------------
-x = 7
<h3>x = -7</h3>
Substitute x = -7 in eqn 1
2(-7) - y = 1
-14 - y = 1
y = -14 - 1 = -15
<h3>y = -15</h3>
Thus the solution to given system of equations are (-7, -15)
