Answer: -9sinx + 3cosx + 4sec^2x
Answer:
Option (2)
Step-by-step explanation:
Given expression is ÷
We further simplify this expression,
÷
=
=
=
Therefore, will be the quotient of the given expression.
and for which the given expression is not defined.
Option (2) will be the answer.
19. It notes or hints to using the quadratic formula because the equation can not be solved by factoring alone. Thus you must use the quadratic formula.
A=-16 B=25 C=3
It is so hard to type a normal equation let alone one of the quadratic formula so I will just attach a picture instead.
However you will end up getting two roots/zeros/x-intercepts of -0.11 and 1.67.
However since it is an application question asking for answers only in the first quadrant you must choose the positive x-intercept.
Therefore the water balloon will land at 1.67 seconds.
20. This question is very simple as it asks you to find a height at a given time. You simply put the given time (1second) into the equation and get your answer.
h=-16(1)^2+25(1)+3
h=12
Also don't mind my little scribble there. :)
