Answer:
38π cm
Step-by-step explanation:
The area of a circle of radius r is A = 2πr.
If the radius is 19 cm, then the area is A = 2π(19 cm), or 38π cm.
Answer: -2, 2, 6, 10, 14
It is an Arithmetic sequence.
Step-by-step explanation:
Given Recursive formula :
, for n ≥ 1 and A(1) = -2.
Hence, the five terms of given sequence= -2, 2, 6, 10, 14
Since, there is common difference of 4 in two consecutive terms.
Therefore, it is an Arithmetic sequence.
Answer:
{x | x ≤ -8}
Step-by-step explanation:
-7x ≥ 56
Divide each side by -7, remembering to flip the inequality since we are dividing by a negative
-7x/-7 ≤ 56/-7
x ≤ -8
4x+30=2(x-10)
4x+30=2x-20
4x-2x= -30-20
2x= -50
x= -25
