Step-by-step explanation:
The curve hits both mark -2 and 0
Answer:

The question wants to determine BOTH at an amount of time.
Green lawn: 28x2=46+42=98 | 28x3=84+42=126
|
These are incorrect | These are correct
Yard guard: 34x2=68+ 24=92 | 34x3=102+24=126
So then 3 months and 126 dollars
I think it’s 20, the 0 to 4 is 9 and the 5 to 9 is 11, 9 + 11 = 20
This is the good part of Trigonometry, actually measuring triangles. It's much better than all the identities around sine and cosine and the rest, which actually have more to do with circles than triangles.
This part of trig has a short menu:
Law of Cosines. Three ways to write it, one is 
Law of Sines: 
Triangle angles: 
and two special cases of the Law of Cosines, the Pythagorean Theorem

and the Collinear Points Theorem:


Here we choose Triangle Angles followed by Law of Sines:
A = 180 - 105 -15 = 60 degrees


Answer: 1.8 cm
When I was a student we'd be expected to get
exactly and get

But that was before online homework.
