Answer:
The answer is A
Step-by-step explanation:
y = mx + c
m = 1/2
(2,-3)
y = (1/2)x + c
-3 = (1/2)(2) + c
c = -4
y = (1/2)x - 4
This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.
Answer:
R = 4cm
Step-by-step explanation:
V = π(R)²h = 480π
Divide by π
(R)²h = 480
Substitute h with 30
30*(R)² = 480
Divide by 30
(R)² = 16
Square root
R = 4cm
We do not accept R= -4 because it's a length, so it must be positive.
