so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
The dollar number that defines where the lowest values falls is
20% percentile value =$20
This is further explained below.
<h3 /><h3>What is the dollar number that defines where the lowest value falls?</h3>
Generally, Now we need to determine the 20th percentile ($20). It indicates that we need to locate a dollar amount that marks the point at which the 20 % data has a value lower than that number.
i=(p/100)*n
Where i is the position of p^th
percentile when the data is presented in ascending order.
i=20/100*50
i=1000/100
i=10
Therefore
n=50
p=20
In conclusion, the 10th position for given data is 20,
Therefore, 20% percentile value =$20

We have the points (1, -6) , (2, -12)
Find the slope (m)
m = (y₂-y₁) / (x₂-x₁)
Plug in the values.
m = (-12 + 6) / (2 - 1)
Simplify.
m = -6/1
So, our slope is : m = -6
We are looking for our equation in point-slope form.
Point-slope form : y - y₁ = m(x - x₁)
Simply plug in everything.
Our given points : (1, -6) and (2, -12)
y - (-6) = -6(x - 1)
Simplify.
y + 6 = -6x + 6
Subtract 6 from both sides.
y = -6x + 6 - 6
Simplify.
So, y = -6x
Your answer is C) y = -6x

Answer:
B) 25°
Step-by-step explanation:
Assuming the quadrilateral is the one shown in the picture attached, then a triangle ADC is form, where m∠ADC = 125° and m∠1 = 30°. The addition of the three angles of a triangle is equal to 180°, so:
m∠ADC + m∠1 + m∠2 = 180°
Replacing with the known values and isolating m∠2 we get:
125° + 30° + m∠2 = 180°
m∠2 = 180° - 125° - 30°
m∠2 = 25°
