Answer:

  yes, it is a function

  domain: {-8, 2 ,4, 5, 6}

  range: {-6, -4, -2}

Step-by-step explanation:

The domain is the set of first values of the ordered pairs: {2, 6, 4, 5, -8}. We often like to see them in order:

  domain: {-8, 2 ,4, 5, 6}

The range is the set of second values of the ordered pairs.

  range: {-6, -4, -2}

There are no repeated values in the domain, so the relation is a function.

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

Plsss help me ASAP !!! you get to win brainlist
TiliK225 [7]

Answer:

122 employees

Step-by-step explanation:

So, first you have to find 22% OF 100 WHICH IS 22. (100x0.22= 22) Then, since they have to lay off 22% more people you add the 22% of 100 (22) to the 100. (100+22=122) This means that they have laid off 122 employees this year. I hope this helps!
