Y=5(3/2)^x is this model exponential growth,decay or neither ?
Answer:
110 in³
Step-by-step explanation:
The volume of a rectangular prism is the product of its dimensions:
V = LWH
V = (10 in)(2 in)(5.5 in) = 110 in³
Time = distance / speed
Time = 3 2/5 miles / 4 miles per hour
Time = 17/5 / 4
Time = 17/5 x 1/4 = 17 x 1 / 5 x 4 = 17/20 hours
17/20 hours x 60 minutes per hour = 51 minutes.
You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
<span>P(t)=P₀a^t
</span>P(t)=6 billion * 101.9%^50= 6 billion * <span>2.56276= 15.38 billion</span><span>
</span>
The surface are of a rectangular prism is:
A=2(xy+xz+yz), where x,y, and z are the dimensions of the prism, in this case:
A=2(4*6+4*8+6*8)
A=2(24+32+48)
A=2(104)
A=208 cm^2
