Basically the first thing you're going to have to do is move the y's to one side of the equal sign. To do this you can either add 0.3y to both sides of the equation OR subtract 0.7y from both sides of the equation.
Answer:
349.5miles
Step-by-step explanation:
Given
Initial time =150min =2.5hours
Initial speed =75mph
Distance = speed x time
Distance = 75*2.5
Distance = 187.5m
Final time =2hours
Final speed =81mph
Distance = speed x time
Distance = 81*2
Distance = 162m
Total distance = initial +final
Total distance = 187.5+162
Total distance = 349.5miles
Answer:
C
Step-by-step explanation:
Multiply the functions.
Answer:
Step-by-step explanation:0.828282 = 0.828282/1 = 8.28282/10 = 82.8282/100 = 828.282/1000 = 8282.82/10000 = 82828.2/100000 = 828282/1000000
And finally we have:
0.828282 as a fraction equals 828282/1000000
Answer: Choice D) I and III
-------------------------------------------------------------
We can rule out equation II because it simplifies to f(n) = 44n-20 which means the height is growing by 44 inches each day, instead of 24
Equation I is true because plugging n = 0 leads to f(n) = 20 which is the proper starting height. Plugging in n = 1 leads to f(n) = 44 (indicating a growth of 24 inches over that first day).
Equation III is true because we start off at 20 inches when it says f(0) = 20, which is the initial value to base the recursion off of. Then we add on 24 each time on the recursive step. Writing f(n) = f(n-1)+24 means "add 24 to the previous term, the (n-1)st term, to get the next term or nth term"
So together Equation I and Equation III are true which is why choice D is the final answer
