<u>ANSWER</u>
True
<u>EXPLANATION</u>
The given trigonometric equation is
Recall the double angle identity:
We apply this identity to obtain:
We maintain the LHS and simplify the RHS to see whether they are equal.
Expand the parenthesis
Recall that:
We apply these identities to get:
Also
Therefore the correct answer is True
Answer:
<h2><em>
2232342</em></h2>
Step-by-step explanation:
2024800 : 100 * 5 = 101240
2024800 + 101240 = 2126040
2126040 : 100 * 5 = 106302
2126040 + 106302 = 2232342
in the first year, it increases by 5% of the original number, making the population at the end of that year 2 126 040. Then, the second year, it will increase by 5% of 2 126 040. This means that the final product or population after 2 years would be 2232342.
Hello, please consider the following.
We know the following, right ?
So, here, it gives.
Do not hesitate if you need further explanation.
Vertical parabola opens down so
(y-k)^2=4P(x-h)
(h,k) is center
P is distance from directix to center and from center to focus (it is 1/2 distance between focus and directix)
-1 to -1/2 is a distance of 1/2
1/2 of 1/2=1/4
P=1/4
so move 1/4 down from -1/2
-3/4
center is (2,-3/4)
so
y+3/4=(x-2)^2
minus 3/4
y=(x-2)^2-3/4
f(x)=(x-2)^2-3/4
you made an error, either the last or first option doesn't have -(x+2)^2
