Ok, so bouncing
when it bounces up, it bounces up
so we double the summation
but for the initial bounce, it only goes down
so we double the whole thing and minus the first bounce
the summation of the geometric sequence where the initial term is
and the common ratio is r and the term is n is
,
and n=30
double and minus 10
the total distance traveled is
it simplifies to
that's the answer is exponential notation
Answer:
Please check explanation
Step-by-step explanation:
Here, in this question, we are interested in identifying the error made by Jillian in his solution of the equation.
This error is traceable to the second step of his solution. Adding 4.3 to 7.05 and subtracting again is the same thing as not adding anything or just adding zero only.
What he should have done is to subtract the value of 4.3 from both sides of the equation. In that manner, he would have been able to isolate v on the left hand side of the equation
-7-1/2-5 because to solve, you do y2-y1/x2-x1
So you get -6/-3, which equals 2
SLOPE IS 2
<span>Let # of nickels = x
So # of dimes = 2x -12, (12 less than twice the # of nickels)
Also when added their total value is $2.55. To show,
0.05(x) + 0.10(2x - 12) = $2.55 -------------- eqn1
continuing,
0.05x+0.2x-1.2=2.55
0.25x = 3.75
x= 15 ------ This is your # of nickels.
In doubt? well just go back eqn1 & substitute x=15, and you get $2.55
2. Let carol's age = x
So, Rauls'age = 2x+5
Adding the their ages will total to 101 years.</span>
