P = A(1+r)^x
where P is the population at time x
A is the initial population and r is the growth/decay rate. Growth will be +positive r number added to the 1. Where as decay subtracts r. So any answers that are > than 1 which is answers A and B.
Answer:
x=2,2/3
Step-by-step explanation:
Hello, Trenties
Thanks for using Brainly,
If you're aloud to, I would fully recommended to graph the points and figure out if they meet or not.
Here's how to find intersections.
To find the intersection of two straight lines:
First we need the equations of the two lines. If you do not have the equations, see Equation of a line - slope/intercept form and Equation of a line - point/slope form (If one of the lines is vertical, see the section below).
Then, since at the point of intersection, the two equations will have the same values of x and y, we set the two equations equal to each other. This gives an equation that we can solve for x
We substitute that x value in one of the line equations (it doesn't matter which) and solve it for y.
This gives us the x and y coordinates of the intersection.

Answer:
m<C = 90°
On applying the concept of vertically opposite angles.
m< C = m<GOE= 90°
Or, we can apply the concept of straight angle
m<DOE is straight angle
m<C +42+48=180°
m<C= 180-90° = 90°
