Find exact values for sin θ and tan θ if cos θ = -4/9 and tan θ > 0.

Part 1)

Part 2)

Step-by-step explanation:

we have that

The cosine of angle theta is negative and the tangent of angle theta is positive

That means that the sine of angle theta is negative

step 1

Find

we know that

we have

substitute

square root both sides

Remember that

In this problem the sine of angle theta is negative

so

step 2

Find

we know that

we have

substitute the given values

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
