Answer:
D
Step-by-step explanation:
The starting term is a1.
That's the very first term.
a1 = - 10
The second term = -17 which means that you added - 7 to - 10.
So d must be - 7
The formula must be
an = a1 + (n - 1)*d
an = -10 + (n - 1)(-7)
You might wonder why it is n - 1. The reason is because the first term is already added on the right side. The -1 means that we have already included the first term.
We should try the formula out to see what it does. Let's find a4
a4 = -10 + (4 -1)*-7
a4 = -10 + 3(-7)
a4 = -10 - 21
a4 = - 31 which is what the question suggests.
(2n^2 + 4n + 4)(4n − 5)
=(2n^2 + 4n + 4)(4n + −5)
=(2n^2)(4n) + (2n^2)(−5) + (4n)(4n) + (4n)(−5) + (4)(4n) + (4)(−5)
=8n^3 − 10n^2 + 16n^2 − 20n + 16n − 20
=8n^3 + 6n^2 − 4n − 20
Answer:
5,444.76 cm3
Step-by-step explanation:
π * r^2 * h
π * 8.5^2 * 24 = 5,444.76 cm3
