Answer:
Usually in the equation they use Sin, Cos, or tan. Although, If the point in the graph starts at 0 is is sin and anything else would be cos. Tan is the sort of vertical squiggly line.
Step-by-step explanation:
3x - 12 = -15
Add 12 on both sides.
-12 + 12 = 0
-15 + 12 = -3
The equation is now 3x = -3.
Divide both sides by 3 to isolate the variable.
3x / 3 = x
-3 / 3 = -1
So, x = -1.
Answer:
37/40
Step-by-step explanation:
5/8 +3/10
We need to get a common denominator of 40
5/8 *5/5 = 25/40
3/10 *4/4 = 12/40
25/40 + 12/40
37/40
Answer:
7^14 / 7^2 = 7^(14 - 2) = 7^12
The differential equation that has the given slope is: dy/dx = -xy.
<h3>How to find the differential equation that models the situation?</h3>
We have to look at the slope, given in the graph of the solution of the differential equation, and represented by dy/dx. From the graph, we have that:
- In quadrants I and III, in which x and y have the same signal, the differential equation is decreasing, hence the slope is negative.
- In quadrants II and IV, in which x and y have different signals the differential equation is increasing, hence the slope is positive.
The differential equation that is negative when x and y have the same signals and positive when they do not have is given by the following option:
dy/dx = -xy.
