Answer:
Step-by-step explanation:
we are given two <u>coincident</u><u> points</u>
since they are coincident points
By order pair we obtain:
now we end up with a simultaneous equation as we have two variables
to figure out the simultaneous equation we can consider using <u>substitution</u><u> method</u>
to do so, make a the subject of the equation.therefore from the second equation we acquire:
now substitute:
distribute:
collect like terms:
rearrange:
by <em>Pythagorean</em><em> theorem</em> we obtain:
cancel 4 from both sides:
move right hand side expression to left hand side and change its sign:
factor out sin:
factor out 2:
group:
factor out -1:
divide both sides by -1:
by <em>Zero</em><em> product</em><em> </em><em>property</em> we acquire:
cancel 2 from the first equation and add 1 to the second equation since -1≤sinθ≤1 the first equation is false for any value of theta
divide both sides by 2:
by unit circle we get:
so when θ is 60° a is:
recall unit circle:
simplify which yields:
when θ is 300°
remember unit circle:
simplify which yields:
and we are done!

Answer:
50
Step-by-step explanation:
represented by 0.6x= 30
solve for x
we know that
Domain:
Domain is all possible values of x for which any function is defined
For finding domain from any graph , firstly we will find smallest x-value and then largest x-value of curve
and that would be domain
Here , we have
smallest x-value is -3
but there is a hole at x=-3
so, function is not defined at x=-3
largest x-value is 1
so, domain would be
