(3, 4) and (5, 12)
Answer: $70 per year.
Step-by-step explanation:
Let's say that x is the number of years that has passed and y is how much the stamp is worth.
So we know that in zero years the stamp was worth $420 because that is the time Sheri gave her brother Sam the stamp. That could bring up the coordinates (0,420) .
Now we know that in 8 years it was worth $980 and that could be the coordinates (8,980)
To find the rate of change we need to find the different between the y value and divide it by the difference in the x values.
420 - 980 = -560
0-8 = -8
-560/-8 = 70
The rate of change is 70 which means that it grew by $70 every year.
Answer:
None of those
Step-by-step explanation:
3! = 3*2*1 = 6
4! = 4*3*2*1 = 24
24 * 6 = 144
144 is none of the choices
Answer:
B. 246 in^2
Step-by-step explanation:
A = pi r^2 theta /360 if theta is in degrees
A = * pi *(16)^2 * (110/360)
A = *pi* 256 * 11/36
A = 2816/36 *pi
A = 245.74236 in ^2
