x<-4
Answer:
B
Step-by-step explanation:
For this problem, I basically solved each equation until it agreed with the sequence.
It's not A or C because when you plug in 1, the number doesn't equal 3.
a = 2(-3)¹⁻¹ = 2(-3)⁰ = 2(1) = 0
a = 3(-2)¹ = -6
It's not D because when you plug in 2, the number doesn't equal -6.
a = 3(2)²⁻¹ = 3(2)¹ = 6
Considering the ballon to be spherical
It's volume is given by 4/3(π r^3) by differentiating volume with respect to time we get rate of change of volume hence,
4πr^2(dr/dt)=600÷60=10
Substituting r=30cm
4π(30)*(30)(dr/dt)=10
dr/dt=rate of increase in bullion's radius=1/(360π)cm/s
You do division from left to right. So, 84/4=21; 21/3=7
So the answer is 7
