Answer:
(3, -7) are the coordinates
Using relations in a right triangle, it is found that:
tan(A) = 3/4 = 0.75.
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
In this triangle:
- The adjacent side to A has length 40.
- The opposite side to A has length 30.
Hence the tangent of A is:
tan(A) = 30/40 = 3/4 = 0.75.

Answer:
36 squared units
Step-by-step explanation:
So you can draw "made up lines" or I guess lines you draw yourself to create 2 rectangles. Check attachment.
The first rectangle is a square and has sides 3 and 3, so you get the area of 9.
The second, has sides 9 and 3, so you get the area of 27
Since you are trying to find the entire thing, you add 27 and 9 to get 36
I am going to assume this is for calculus. You would need to find the derivative of each because derivative represents rate of change.
The derivates are:
y'=1
y'=3
y'=4
y'=2
Therefore the answer it the third choice because it has the largest derivative<span />
Given that the monthly cell phone bill is determined by a fixed monthly fee of $35
for 300 anytime minutes and $.40 for each additional minute used.
Dependent variables can be the result of more than one independent
variable.
Consider your phone bill as presented above. Aside from being
charged for minutes over 300, you are charged $1.25 for each directory
assistance call and $.75 per minute for long distance roaming calls. You
also have to contribute at least $1.50 to the federally required
Universal Service Fund per month and this value may vary on your phone
bill but is not an independent variable.
<span>To write
an equation expressing your monthly cost using the below independent
and dependent variables.
Let x = additional minutes used, then the cost for additional minutes used is given by 0.4x.
Let d = number
of directory assistance calls made, then the cost for directory assisitance is given by 1.25d.
Let r = number of long distance
minutes used, then the cost for long distance minutes is given by 0.75r.
Let u = USF monthly charge.
Let y = total monthly bill, therefore the total monthly bill is given by
y = 0.4x + 1.25d + 0.75r + u</span>
