Answer:
Felipe is correct
Step-by-step explanation:
Note the difference between consecutive terms is constant, that is
16 - 24 = 8 - 16 = 0 - 8 = - 8
This indicates the sequence is arithmetic
The explicit formula for an arithmetic sequence is
f(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 24 and d = - 8, thus
f(n) = 24 - 8(n - 1) = 24 - 8n + 8 = 32 - 8n ← Felipe's answer
As the graph shows,z(3,4),w(-4,1)
so,w-z(-4-3,1-4)⇒(-7,-3)
z-w(3-(-4),4-1)⇒(3+4,3)⇒(7,3).
Answer:
My answer is 57.776
Step-by-step explanation:
Diameter= 9.2 km
3.14×2 = 6.28
6.28× 9.2
= 57.776
Dunno about rounding it to tenths cause that would be 60
Answer:
-5 & 1
Step-by-step explanation:
[x² + 2(x)(2) + 2²] - 2² - 5 = 0
(x+2)² - 4 - 5 = 0
(x+2)² = 9
x+2 = +/- 3
x+2 = 3 x = 1
x+2 = -3 x = -5
