A town has a population of 5000 and grows at 3.5% every year. What will be the population after 15 years, to the nearest whole number? Exponential Functions:
y=ab^x
y=ab
x
a=\text{starting value = }5000
a=starting value = 5000
r=\text{rate = }3.5\% = 0.035
r=rate = 3.5%=0.035
\text{Exponential Growth:}
Exponential Growth:
b=1+r=1+0.035=1.035
b=1+r=1+0.035=1.035
\text{Write Exponential Function:}
Write Exponential Function:
y=5000(1.035)^x
y=5000(1.035)
x
Put it all together
\text{Plug in time for x:}
Plug in time for x:
y=5000(1.035)^{15}
y=5000(1.035)
15
y= 8376.74415
y=8376.74415
Evaluate
y\approx 8377
y≈8377

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
