Answer:
A. 100 - 5d
Step-by-step explanation:
When d=0, Rosa has 100 miles remaining. That fact eliminates choices C and D, which do not give the value 100 when d=0.
After Rosa runs 1 day, she has 95 miles remaining. That eliminates choice B, which tells you she has 105 miles remaining.
The only viable choice is A.
_____
You could write this expression yourself by realizing that Rosa starts with 100 miles remaining and decreases that amount by 5 each time the value of d increases by 1. That is, the expression 5d represents the number of miles Rosa runs in d days. This number is subtracted from her goal to give the remaining miles, so 100-5d is the number she has remaining of her goal.
Answer:
The power is 1.68 W.
Step-by-step explanation:
Voltage, V = 3 V
charge, q = 0.56 C
time, t = 1 s
The power is given by
P = V q/t
P = 3 x 0.56 / 1
P = 1.68 W
Answer:
3d - 4 = -0.4
When d = 1.2
Step-by-step explanation:
Use PEMDAS to solve the equation
3(1.2) - 4
= 3.6 - 4
= -0.4
The answer is 4.
Yes I think it works nicely, lol
Hope this helps!
