Answer:
They ran it equally
Step-by-step explanation:
89/100 equals 0.89: 89 divided by 100 = 0.89.
The simple interest rate equation is I = Prt
I = interest
P = principle ($54,000)
r = rate (3.875%)
t = time (3 months, so .25 years)
I = Prt
I = (54,000)*(.03875)*(.25)
I = $523.125
Answer: The maximum depth that he will reach is -125 meters.
The first thing you should realize is that this is a quadratic equation and the graph will be a parabola.
We can simply the equation to:
y = (1/20)x^2 - 5x
Now, use -b/2a to find the x-value of the vertex which is 50. Then, input 50 back into the equation to get -125 for the maximum depth.
There are 5 little lines between 0 and -1, so each line represents 1/5.
B is located 3 lines to the left of -1, so it would be located at - 1 3/5.
Am absolute value is a positive number so - 1 3/5 would become 1 3/5.
The answer would be A. 1 3/5
