Answer:

Step-by-step explanation:
We see that the two terms share an x, so we can pull that out:

Now notice that we have a difference of squares (
). Given a difference of squares,
, this can always be factored into
. We can use this in this case:
.
So, our final factorized form is:
.
Hope this helps!
Answer:
B. Square root
Step-by-step explanation:
using distance formula:
x = √z^2 - y^2
y = √z^2 - x^2
=> z = √x^2 + y^2
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j
see attached picture:
16% of 231 is 36.80
16% + 84% = 100%
36.80+ 231 = $267.80
Ans = $267.80
Answer:
D is the answer
64,000 exponential function
Step-by-step explanation:
64,000 exponential function
The number of bacteria in a colony doubles every 210 minutes.
The population of bacteria = 8000
Determine how many times the population will double.

= 3
Multiply the population by 2 a total of 3 times.
8000 × 2³ = 64,000
