Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
Answer:
the answer is 3/16.
Step-by-step explanation:
First, let's take a look at the expression itself.
We have to multiply 3/8 and 1/2, which gives us the expression of
3/8*1/2
then, we multiply the numerator by the numerator and get 3, then we multiply the denominator by the other denominator which gets us 16. We put the two parts together and get
3/16
which is not simplifiable. So 3/16 is the simplest answer we can get.
Answer:
Step-by-step explanation:
For species A,

For species B,

When their populations are equal,

The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.
Answer:
0.925 or 92.5%
Step-by-step explanation:
y=a(1-b)^x
decay factor is 1-b <- and the part we care about
b is 7.5%=0.075
1-0.075
=0.925
I'm a little rusty on exponential rates, but I hope this helps!
