The correct question is
<span>Given cos theta=4/9 and csc theta < 0 find sin theta and tan theta
</span>
we know that
csc theta=1/sin theta
if csc theta < 0
then
sin theta < 0
we have that
<span>cos theta=4/9
we know that
sin</span>² theta+cos² theta=1
so
sin² theta=1-cos² theta-----> 1-(4/9)²----> 1-(16/81)----> 65/81
sin theta=-√(65/81)---->-√65/9
the answer Part a) is
sin theta=-√65/9
Part b) find tan theta
tan theta=sin theta/cos theta
tan theta=(-√65/9)/(4/9)-----> tan theta=-√65/4
the answer part b) is
tan theta=-√65/4
I this the answer you are looking for would probably be 47.7%.
hope this helps!!
Answer:
-3
Step-by-step explanation:
you start with the parentheses -16-9 turns into -16 + (-9)
and then you try to solve everything.
We’ll use probability to answer this question.
Probability: Number of even numbers / All numbers added together.
Odd numbers: 1,3,7
Even numbers: 4
All numbers added together (amount of numbers not the numbers itself!) = 4
Amount of even numbers = 1
Probability of getting an even number is 1/4
Answer: Yes she is correct, the probability of getting an even number is 1/4.
