The value of the angle θ is 160.52° then the value of the cosine will be negative 0.9428.
<h3>What is trigonometry?</h3>Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Angle θ is in standard position.
If sin(θ) = − 1/3 , and π < θ < 3π/2
Then the angle will be
Then add 180 degrees, then we have
Then the value of the cosine will be

Answer:
vertex is (2,-5)
Step-by-step explanation:
y = a(x – h)^2 + k
the vertex is (h,k) in the equation h =2 and k = -5
Answer:
s ≈ 105
Step-by-step explanation:
<u>Given:</u>
<u>To find:</u>
<u>Steps:</u>
To find the standard deviation, first write the computational formula for the standard deviation of the sample.
Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by . Here, we round the standard deviation to the nearest whole number.
Rounding to the nearest whole number:
s ≈ 105
