Answer: Add the number previously added multiplied by 3;
+3x, where x is the number that was added previously
Step-by-step explanation:
3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.
Answer:
im stuck on that too man
Step-by-step explanation:
Let wind speed = x mph
when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.
when riding with the wind we have
20 + x = 3 / t--------(2) adding equations (1) and (2):-
40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr
x = 20 - 2 / 1/8 = 20 - 16 = 4
Wind speed was 4 mph Answer
Answer:
The position of particle at 1 second is 4 feet.
Step-by-step explanation:
We are given the following in the question:
where s is a position function and measure in feet and t is measured in seconds.
We have to evaluate the position at 1 second.
Putting t = 1 in the position function, we get.
Thus, the position of particle at 1 second is 4 feet.
