Are you missing an option? The answer should be -2/3 (I just calculated it numerous times)
Cos Ф - cos Ф.sin² Ф
sin² Ф = 1 - cos² Ф
cos Ф - cos Ф( 1-cos² Ф) = cos Ф - cos Ф - cos³ Ф = cos³ Ф
cos Ф - cos Ф.sin² Ф = cos³ Ф
Answer:
A) x-3 and D) x+9
Step-by-step explanation:
x^2 + 6x - 27
You need to find two numbers that multiply to -27 and add up to 6
Those two numbers are -3 and 9, because 9 * -3 = -27 and 9+ -3 = 6
So you add those to x and those are your two factored binomials
(x-3) and (x+9)
The graph represents a function but the table does not. The reason for this is that one input value (70) in the table is associated with two output values (54.6 and 53.11), which is a sure sign that we do NOT have a function here.
To solve this problem you must apply the proccedure shown below:
1. First, you must multiply $8 by the hours given in the exercise:
2. Now, multiply the result obtained above by 4, to calculate her monthly income:
3. If 22% of her paycheck goes to taxes, you have:
![(800dollars)-[(800dollars)(0.22)]=624dollars](https://tex.z-dn.net/?f=%28800dollars%29-%5B%28800dollars%29%280.22%29%5D%3D624dollars)
Therefore, the answer is: $624
