Answer: The equation of a circle with center (h,k) and radius r is given by (x−h)2+(y−k)2=r2 . For a circle centered at the origin, this becomes the more familiar equation x2+y2=r2
Step-by-step explanation:
Number of strings =
= 21 x 21 x 21 x 21 x 21 x 5 = 20 420 505
Answer: 20 420 505
Answer:
-1/3
Step-by-step explanation:
if we use the rise over run method we see a fall of 1 and a run of 3. since we are using fall instead of rise that makes this slope negative. hope this helped :)
Answer:
Step-by-step explanation:
.
m is the slope of the line. To find it we can do 
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: 
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant 
.
- Re-arranging to get b
Now re-write the equation as we have the constants.
A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years
b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time
if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57
