The area of the interior above the polar axis is -0.858 square units
<h3>The area bounded by a polar curve</h3>
The area bounded by a polar curve between θ = θ₁ and θ = θ₂ is given by
Now, since we have the curve r = 1 - sinθ and we want to find the area of the interior above the polar axis, we integrate from θ = 0 to θ = π, since this is the region above the polar axis.
So,
So, the area of the interior above the polar axis is -0.858 square units

Answer:
563.53%
Step-by-step explanation:
Suzanne's cell phone monthly bill = $85
Suzanne's cell phone yearly bill = 85*12 = $1020
Suzanne's student health insurance yearly bill = $181
Therefore,
1020/181=5.63*100 = 563.53%
The money spent on her cell phone bill is 563.53% of the money spent on student health insurance.
On an annual basis, the first set of expenses (cell phone) is 563.53% of the second set of expenses (health insurance)

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Z score is given by:
z = (raw score - mean) / standard deviation
Given that mean score is 76, and the standard deviation is 8.
For x > 90:
z = (90 - 76) / 8 = 1.75
P(z > 1.75) = 1 - P(z < 1.75) = 1 - 0.9599 = 0.0401
About 4.01% of the test scores in the normal distribution that are greater than 90

Answer:
it has six sample spaces they are 1,1,1,2,3 and 4
X+6=4x-21
X-4x=-21-6
-3x=-27
X=9
CD = 9+6=15
