cos(a - b) - cos(a + b) = 2sin(a)sin(b)
[cos(a)cos(b) + sin(a)sin(b)] - [cos(a)cos(b) - sin(a)sin(b)] = 2sin(a)sin(b)
[cos(a)cos(b) - cos(a)cos(b)] + [sin(a)sin(b) + sin(a)sin(b)] = 2sin(a)sin(b)
2sin(a)sin(b) = 2sin(a)sin(b)
The answer is c i'm pretty shure
Answer:
Step-by-step explanation:
(3a^4b^3)^3
=3^3a^4*3b^3*3
=27a^12b^9
Answer:
Domain = All real numbers
Range = y ≥ 0
Step-by-step explanation:
As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers
Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it <em>can</em> still be 0) Since y can only be positive... we define the Range as y ≥ 0
The coordinate of point Y such that the ratio of MY to YJ is 2:3 is 6.4
<h3>How to determine the point?</h3>
The complete question is added as an attachment
The coordinates are given as:
M = 2
J = 18
The ratio is given as:
Ratio = 2 : 3
The location of the point Y is then calculated as:
Y = Ratio * (J - M)
This gives
Y = 2/(2 + 3) * (18 - 2)
Evaluate
Y = 2/5 * 16
This gives
Y = 6.4
Hence, the coordinate of point Y such that the ratio of MY to YJ is 2:3 is 6.4
