Answer:
See below
Step-by-step explanation:
It has something to do with the<em> </em><u><em>Weierstrass substitution</em></u>, where we have

First, consider the double angle formula for tangent:

Therefore,

Once the double angle identity for sine is

we know
, but sure, we can derive this formula considering the double angle identity

Recall

Thus,
Similarly for cosine, consider the double angle identity
Thus,

Hence, we showed

Answer:
Option A is correct.
is the equation represent the point slope form gives the plant's height at any time.
Step-by-step explanation:
Point slope intercept form: For any two points
and
then,
the general form
for linear equations; where m is the slope given by:

Consider any two points from the table;
let A= (2 , 16) and B =(4, 32)
First calculate the slope of the line AB:
= 8
Therefore, slope of the line m = 8
Then,
the equation of line is:
Substitute the value of m=8 and (2, 16) above we get;

Therefore, the equation in point slope form which gives the plant's height at any time is;
, where x is the time(months) and y is the plant height (cm)
Answer:
The first answer is 4 and so is the next box. The last one is 10.
Step-by-step explanation:Use your formula. It gave you y=x-3, so every Y point in the able will be 3 less than its corresponding x point.
Answer:

Step-by-step explanation:
Multiply the two polynomials by multiplying each term

Answer:
- 127.3
- 52.7
- 127.3
- 52.7
Step-by-step explanation:
Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).
52.7 + x = 180
x = 127.3
Best of Luck!
