Step-by-step explanation:
Given
-- initial
Required
The exponential equation
The exponential equation is
Where
We used minus, because the rate decreases..
So, we have:
So:
Hence:
Answer:
=
And the limit on this case exists.
Step-by-step explanation:
We want to find the following limit:
First we can distribute the polynomials like this:
And Now we can use the distributive property for the limit and we got:
And now we can evaluate the limit and we got:
=
And the limit on this case exists.
Answer:
3 days
Step-by-step explanation:
hiking = every 12 days = 1 day
swimming = every 9 days = 1 day
today = he did both exercise = 1 day
find:

= 3 days
Answer:2x2−7x−15
Step-by-step explanation:
(2x+3)(x−5)
=(2x+3)(x+−5)
=(2x)(x)+(2x)(−5)+(3)(x)+(3)(−5)
=2x2−10x+3x−15
=2x2−7x−15
