It's exponential. And you will triple the size every 60 minutes in 240 minutes, so triples 4 times. 2000 times 3 is 6000. 6000 times 3 is 18000. 18000 times 3 is 54000. 54000 times 3 is 162000 so D is the answer.
Answer:
g(1)=-12, g(n)=g(n-1)*1/6
Step-by-step explanation:
From the explicit formula -72 and ( <u>1/6</u> )^n-1
the first term of the sequence is -72 and the common ratio is 1/6.
So, we know that g(1), which is the first term, is -72
and that g(n)=g(n-1)*1/6 is the common ratio.
hope this helps :-)!
Area of square = 24cm²
⇒ Length = √24
Find the diagonal of half the square:
a² + b² = c²
c² = (0.5√24)² + (√24)²
c² = 6 + 24
c² = 30
c = √30
The diagonal of half of the square is the radius of the circle.
⇒ radius = √30
Area of the semicircle = 1/2πr² = 1/2π(√30)² =15π
Answer: 15π²
