Answer:

3x^2 - 6x - 9

Step-by-step explanation:

In order to make the function have zeros at -1 and 3 it needs to factor into:      

<u>To make that:</u>

3x^2 - 6x - 9

(3x - 9)(x + 1)

<u>To check:</u>

3x - 9 + 9 / 3 = 0 + 9 / 3

x = 3

x + 1 - 1 = 0 - 1

x = -1

So, it is correct.  

Answer:  3x^2 - 6x - 9

Natali [406]

Given :

A sailor is 30 m above the water in the crow's nest on a sailboat.

The sailor encounters an orca surface at an angle of depression of 15 degrees.

The crows nest is 20 m horizontally from the bow (front) of the boat.

To Find :

How far in front of the boat is the orca.

Solution :

Let, distance of boat front from the crow's nest is x.

So,

\dfrac{30}{20+x}=tan \ 15^{\circ}\\\\x=\dfrac{30}{tan \ 15^{\circ}}-20\\\\x=111.94-20\\\\x=91.94\ m

Hence, this is the required solution.
