a culture started with 6000 bacteria after 6 hours it grew to 7200 bacteria predict how many bacteria will be present after 17 h
Zigmanuir [339]
First find the rate of growth using the formula of
A=p e^rt
A 7200
P 6000
E constant
R rate of growth?
T time 6 hours
We need to solve for r
R=[log (A/p)÷log (e)]÷t
R=(log(7,200÷6,000)÷log(e))÷6
R=0.03 rate of growth

Now predict how many bacteria will be present after 17 hours using the same formula
A=p e^rt
A ?
P 6000
R 0.03
E constant
T 17 hours
A=6,000×e^(0.03×17)
A=9,991.7 round your answer to get
A=9992

On cyber Monday a 40$ hard drive was discounted by 30%. If the tax rate in your city is 7%, what is the total cost of the hard d
Georgia [21]

The total cost of hard drive is $29.96

Step-by-step explanation:

Given,

Original price = $40

Discount = 30%

Discount amount = 30% of $40 = \frac{30}{100}*40

Discount amount=\frac{1200}{100}= \$12

Price after discount = Original price - discount amount

Price after discount = 40-12 = $28

Tax rate = 7%

Tax amount = 7% of price after discount

Tax\ amount=\frac{7}{100}*28\\Tax\ amount=\frac{196}{100}\\Tax\ amount=\$1.96

Total cost of hard drive = Price after discount + Tax amount

Total cost of hard drive = 28+1.96 = $29.96

The total cost of hard drive is $29.96
