49.5(0.82)^x

1 answer:

3 0

You are correct in stating you have a decay. This is because the base of the exponential 0.82 is in the form 1+r where 1+r = 0.82 solves to r = -0.18

The negative r value means we have decay.

The rate of decay is 18% since 0.18 = 18/100 = 18%

For example, if we started with 100 items then after 1 unit in time, you'd have 82 items since 100-18 = 82

Solve the equation of the function for n.

a(n) = 3n - 20

a = 3n - 20

a + 20 = 3n

(a + 20)/3 = n

n = (a + 20)/3

n(a) = (a + 20)/3

Hi! I'm happy to help!

We can see that A's coordinates currently are -6 for x and 2 for y.

When we move x+3, it moves the x coordinate to the right 3 units. This changes it from -6 to -3. When we move y -2, we move the y coordinate down 2 units. This changes it from 2, to 0.

To sum it up: The final coordinates of A will be -3 for x and 0 for y, also written as (-3,0).

I hope this was helpful, keep learning! :D
