Answer:
The area is 452.39
The Circumference is 75.36
Step-by-step explanation:
Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />
Answer:
450,425
Step-by-step explanation:
2000 1200 800 600 500 450 425
-800 -400 -200 -100 -50 -25
÷2 ÷2 ÷2 ÷2 ÷2
The answer is 25. To check 10/.4 is 25 and 0.4 equals to 2/5
