Answer:
Answer: There is also a connection between multiplication of complex numbers and polar coordinates. As usual, polar coordinates of a point ( x , y ) in the plane are defined as ( r , θ ) where r is the length of the vector ( x , y ) and θ is the angle this vector makes with the positive x axis.

Step-by-step explanation:
80(miles) x 52(weeks in a year) = 4160(miles in a year)
4160 / 4(tunes in a year) = 1040(miles to go before a tune)
Now for Christine
100(miles) x 52(weeks in a year) = 5200(miles in a year)
5200 / 1040(miles to go before a tune) = 5(tunes in a year)
Answer C. 5
M=dc/dp=4/6=4/6=2/3
c(p)=2p/3 +b using (6,4)
4=2(6)/3+b
4=4+b, b=0 so
c(p)=2p/3

Answer:
x = 30
Step-by-step explanation:
We know that the angle is a right angle, which is equal to 90. So in order to see what the equation is equal to, we have to subtract 81 from 90.
90 - 81 = 9
With the answer we get, we can now begin to solve for x.
2x - 51 = 9, add 51 to both sides
2x = 60, divide 60 by 2 to get x
x = 30
Now, to check your work, plug 30 into the equation.
2(30) - 51
60 - 51 = 9

Given:
In △ABC is a right angle triangle.
AC is 6 units longer than side BC.
To find:
The length of AC.
Solution:
Let the length of BC be x.
So, Length of AC = x+6
According to the Pythagoras theorem, in a right angle triangle
△ABC is a right angle triangle and AC is hypotenuse, so
![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Subtract 68 from both sides.
Divide both sides by 2.
Splitting the middle term, we get
Side cannot be negative, so x=2 only.
Now,
Therefore, the length of AC is 8 units.
