Answer:

Step-by-step explanation:
Set it up as a proportion in correspondence with their unit of measurement:
![\frac{16}{21,3} = \frac{25}{?} → \frac{[21,3][25]}{16} → \frac{532,5}{16} = 33,28125 \\ \\ 33,3 ≈ P](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%2C3%7D%20%3D%20%5Cfrac%7B25%7D%7B%3F%7D%20%E2%86%92%20%5Cfrac%7B%5B21%2C3%5D%5B25%5D%7D%7B16%7D%20%E2%86%92%20%5Cfrac%7B532%2C5%7D%7B16%7D%20%3D%2033%2C28125%20%5C%5C%20%5C%5C%2033%2C3%20%E2%89%88%20P)

Step-by-step explanation:
The vertical line test is a test used to determine whether a relation is also a function. It is done by inserting several vertical lines that intersect the relation. If a vertical line intersects the relation at multiple point, then it is not a function. If every single inserted vertical line intersects the relation at only one point, then the relation is a function.
We have that
y=sin x
for x=2theta
<span>theta = pi/4 radians
so
x=2*pi/4-----> x=pi/2
using a graph tool
see the attached figure
for x=pi/2
y=sin pi/2------> y=1
</span>
the solution is1
Answer:
y = -(x+4)² +7
Step-by-step explanation:
I find it convenient to factor the leading minus sign from the first two terms, then work with what's left.
... y = -(x² +8x) -9
Now, add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
... y = -(x² +8x +4²) -9 +4²
... y = -(x +4)² +7 . . . . . . . . . rewrite parentheses as a square; collect terms
