Answer:
144
Step-by-step explanation:
Remark
Well you could do this the brute force way. 32 is the nineth term in the series. Sum = 0 + 4 + 8 + 12 + ... 32 = 144. That will get you an answer.
This works unless you are asked for the 44434th term. Then you better use a formula. Even the hundredth term would be trouble.
Step One
Find d
d is given as 4
Step 2
find n. There are 9 terms. The 9 is given.
Step 3
Find the ninth term.
<em><u>Givens</u></em>
a1 = 0
n = 9
d = 4
<em><u>Formula for the 9th term: </u></em>a9 = a1 + (n - 1)*d
Substitute and Solve
a9 = 0 + (9 - 1)*4
a9 = 8*4 = 32
Step 4
Find the sum of the first 9 terms
Sum = (a1 + a9)*n/2
Sum = (0 + 32)*9/2
Sum = 32 * 9/2
Sum = 32 * 4.5
Sum = 144
Yes, for 6 x 8 = 48, and 48 > 46
you have to have enough buses for each person, and none of them are walking, and so you will need 8 minivans
hope this helps
Answer:I believe its c
Step-by-step explanation:
1/27 = 3^(-3)
3^(3x+6) = 3^(-3)
When bases are the same, all you need to do is set the exponents equal to each other:
3x+6 = -3
3x = -9
x = -3
Answer with Step-by-step explanation:
We are given that a function
on the interval [-1,1]
Rolle's theorem : It states that function is continuous on close interval [a,b] and differentiable on open interval (a,b) such that f(a)=f(b) , then
for some x
f is not differentiable at x=0.Therefore , f(x) is not diffrentiable on interval (-1,1)
Hence, Rolle's threorem cannot be applied for given function because it does not satisfied the condition of rolle's theorem.
