Answer:
90° CCW
Step-by-step explanation:
The angle from C to the origin to C' is a right angle when measured counterclockwise (in the usual direction).
ΔA'B'C' is a rotation of ΔABC 90° CCW.
__
This is fully equivalent to a rotation of 270° CW.
Answer:
The insect population after 6 days is of 1639 insects.
Step-by-step explanation:
A population of insects increases at a rate 230 + 8t + 0.9t2 insects per day
This means that
The population of insects after x days is given by:
So
In which K is the initital population(which is 50). So
After 6 days:
Rounding to the nearest insect, 1639
The insect population after 6 days is of 1639 insects.

Answer:
x=14.3
Step-by-step explanation:
its the Pythagorean theorem
Answer:
-2^(x-2)
Step-by-step explanation:
Using differential calculus:
We know that the integral of 1/x = ln(x)
or 2x/ln(2) = log2(x), so we plug in our knowledge and chain rule to figure out that the answer to the inverse is -2^(x-2) :)
