V = (-7,-4)
8v would be 8 times both numbers
8v = (8*-7, 8*-4)
8v = (-56, -36)
magnitude = square root( -56^2 + -36^2)
= sqrt(3136 + 1296)
= sqrt(4432 )
= 4 sqrt(277)
I think 7x-y=-2 is the answer
All i know is that if the radius of a circle is 4 feet, the the diameter is 8 feet. Sorry, I don't know the rest.
The first thing we must do in this case is to rewrite the length of the first tape.
We have then:
4/8 = 2/4 = 1/2 = 3/6 yard
Therefore, since the tapes have the same length, the following measure is NOT possible:
4/6 yard
Answer:
A. 4/6 yard
Y=30x+50
y is the total amount saved
x is the amount of months she deposited 30 dollars
30 is the amount she’s depositing
50 is the initial amount or the constant
