Answer:
decay
2% decrease
Step-by-step explanation:
The growth factor is the base of the exponent: 0.98. Its relation to the rate of change is ...
growth factor = 1 + rate of change
0.98 = 1 + (-0.02)
So, the rate of change is -0.02 = -2%. Since the rate of change is a 2% decrease, it represents decay.
Write an equation system where x=cost of notebook, y=cost of pencil, z=cost of pen.
3x+4y+2z=5.45
5x+2y+3z=7.80
2x+5y+4z=7.15
Solve this system and you get x= $1.25 per each notebook, y= $0.25 per each pencil, z= $0.35 per each pen
using the given equation, d would be the distance which is given as 7 miles.
replace d with 7 and solve for h
7 = 5/6 SQRT(h)
divide both sides by 5/6
7 / 5/6 = sqrt(h)
8.4 = sqrt(h)
raise both sides to the 2nd power:
8.4^2 = h
h = 70.56
h = 71
The answer is B. 71 feet.
Yes one is a probability because it can be one out of 4 or something
Good luck hope this helps
