In scoop county 16.8% of residents have diabetes. If 12,914 scioto county residents have diabetes, what is the population of the
Sergeu [11.5K]

The population of the county is 76,869.

Step-by-step explanation:

Given,

Number of people with Diabetes = 12914

Percent of people with Diabetes = 16.8%

Let,

x be the number of people in county.

16.8% of x = 12914

\frac{16.8}{100}x=12914\\0.168x=12914

Dividing both sides by 0.168

\frac{0.168x}{0.168}=\frac{12914}{0.168}\\x=76869.04

Rounding off to nearest whole number

x = 76,869

The population of the county is 76,869.

A certain culture of year increases by 50% every three hours. A scientist places 9 grams of yeast in a culture dish. Write the e
miskamm [114]

Answer: a) Explicit formula :f(x)=9(1.5)^{3x}

b) Recursive formula : f(x)=9(1.5)^{3x} and f(x+1)=f(x)\times 1.5^3

Step-by-step explanation:

Since we have given that

Number of grams of yeast in a culture dish initially = 9 grams

According to question, a certain culture of year increases by 50 % every three hours.

So, the explicit formula will be

f(x)=9(1+\frac{50}{100})^{3x}\\\\f(x)=9(1+0.5)^{3x}\\\\f(x)=9(1.5)^{3x}

And the recursive formula will be

f(x)=9(1.5)^{3x}\\\\f(x+1)=9(1.5)^{3(x+1)}\\\\f(x+1)=9(1.5)^{3x+3}\\\\f(x+1)=9(1.5)^{3x}.(1.5)^3\\\\f(x+1)=f(x)\times 1.5^3

Hence, a) Explicit formula : f(x)=9(1.5)^{3x}

b) Recursive formula :f(x)=9(1.5)^{3x} and  f(x+1)=f(x)\times 1.5^3
