Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
Answer:
b=4
Step-by-step explanation:
4b + 5 = 1 + 5b
Subtract 4b from each side
4b-4b + 5 = 1 + 5b-4b
5 =1+b
Subtract 1 from each side
5-1 = 1-1+b
4 =b
Answer:
slope = 2/5 and y Intercept = -5
y = 2/5x - 5
Answer: 0.785 (if you have to, round)
Step-by-step explanation:
1/2=0.5
0.5*0.5=0.25
0.25*3.14=0.785
