Answer:
512(cm)3
Step-by-step explanation:
Answer:
and 
Step-by-step explanation:
Think about it.
What two numbers multiply to -15 and add up to 2?
The answers are 5 and -3.
So plug that into the factored form of a parabola.

To find the x-intercepts, plug in 0 for
.

Since we are multiplying, at least one of the terms has to equal 0.

So the x-intercepts are
and
.
Since the signs are different, you have to subtract. 2
Answer:
Explicit: a₁=61 aₙ=a₁ -3ₓ(n-1)
Recursive: a₁=61 aₙ=aₙ₋₁ - 3
Step-by-step explanation:
Explicit: a₁=61 aₙ=a₁ -3ₓ(n-1)
Recursive: a₁=61 aₙ=aₙ₋₁ - 3
(3d x 6) + 1 = (9 x 4) + 2
-> 18d + 1 = 36 + 2
-> 18d = 38 - 1
-> 18d = 37
-> d = 37/18
-> d = 2.056
