I’m retailing there is a direct interaction with the answer is all of the above
Answer:
Part I : 100°
Part II : a = 29.2
Part III : b = 20.95
Step-by-step explanation:
See the attached diagram of the triangle.
Part I: ∠ A = 180° - ∠ B - ∠ C = 180° - 45° - 35° = 100°
Part II: Now, applying the law of sines, we have
⇒
⇒
⇒ a = 29.2 (Answer)
Part III: Now, applying law of cosine, we have
b = a cos 35° + c cos 100° = 29.2 cos 35° + 17 cos 100° = 20.95 (Answer)
4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.

To find the inverse of this function, we first need to replace f(x) with y.
y = 2x^2 + 3
Now, we swap x and y
x = 2y^2 + 3
Now, we solve for y.
-3
x - 3 = 2y^2
Sqrt both sides.
√(x - 3) = 2y
Divide by 2
√(x - 3)/2 = y
Replace y with f^-1(x)
√(x - 3)/2 = f^-1(x)
Just realized you were asking for f(-1), not f^-1(x)
Feels bad.
f(-1) = 2(-1^2 + 3)
f(-1) = 2(-1^5)
f(-1) = 2(-1)
<u>f(-1) = -2</u>
I'm leaving the original answer in case you also need the inverse function. :)
