Step-by-step explanation:
It is convenient to let a spreadsheet compute each table value as 1.1 times the value on the previous line.
When the growth rate is 10% per year, the growth factor is 1 +10% = 1.10. This is the value that multiplies the investment each year.
Miles per 1 hour
360/6=60 miles per hour
Answer:
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).
Answer:
x=11
Step-by-step explanation:
If both buses travel with an average speed of 45 mi/h and we want to find when will they be 400 miles apart, we need to find when one of them will be 200 miles from its start point. To do it let's see how long does it take to make 1 mile:
45 miles per hour = 45/60 mile per minute = 3/4 mile per minute = 0,75 mile per minute
200 ÷ 3/4 =
= 200 * 4/3 =
= 800/3 =
= 266 2/3 [minutes] =
= 4 hours 26 minutes 40 seconds
That's how long it takes for one bus to be 200 miles from its start point. It also means that both buses will be 400 miles apart after 4 hours 26 minutes and 40 seconds of driving opposite directions.
