Answer:
8.7 cm
Step-by-step explanation:
take 60 degree as reference angle
using sin rule
sin 60=opposite/hypotenuse
=opposite/10
=opposite
= opposite
=opposite
8.66=opposite
8.7 =opposite

Answer:

Step-by-step explanation:
Given this function:

We need to find the value of:

This is really simple because the problem give us the following data:

Using this data we can write a 2x2 system of equations like this:
Let:

and

Our system will be:

We can solve this system using different methods, however I will use elimination method because I believe it is really simple. So:

Replacing
into (1)

Now we found the values of
and
, our function is given by:

Let's verify it:


As you can see the function satisfies the data provided by the problem. So we can conclude that it is correct.
Finally, let's find
for
:

Hence:

Y = -12x + 2
The graph is a straight line....true, it is linear
The line does not pass thru the origin (0,0).....true, it does not
The line passes thru the point (0,-2)...false, it does not
The y int of the line is 2......true, it is
