Answer: $86.25
Step-by-step explanation:
For this problem, we are given p, r, t.
p=70 (starting amount)
r=0.11 (11%)
t=2 (years)
We can plug this into the equation B=p(1+r)^t
B=70(1+0.11)^2
B=86.247
Sam would have $86.25
Answer: C) 2 dimensions; flat surface of length and width, but no depth
One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.
Answer:
no
Step-by-step explanation:
this is because when dealing with the power, it involves multiplication
Answer = 2 plus 5 times n
Answer:
a) 
b) 
Step-by-step explanation:
Polar coordinates are represented as:
, where 'r' is the length (or magnitude) of the line, and '
' is the angle measured from the positive x-axis.
in our case:

to covert the polar to cartesian:


we can plug in our values:


the Cartesian coordinates are:


(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'



the angle can be found by:




to convert radians to degrees:

writing in polar coordinates:
