The total revenue from the sale of a popular book is approximated by the rational function R(x) = 1000x^2 / x^2+4​, where x is t
Alenkinab [10]

Answer:

(a)$200 Million.

(b)$500 Million.

Step-by-step explanation:

Total Revenue, R(x)=\dfrac{1000x^2}{x^2+4}

(a)At the end of the first year, x=1

R(1)=\dfrac{1000*1^2}{1^2+4}\\=$200

Total revenue at the end of the first year is $200 Million.

(b)At the end of the second year, x=2

R(2)=\dfrac{1000*2^2}{2^2+4}\\=$500

Total revenue at the end of the second year is $500 Million.

A die is thrown . find the probability of (1) a multiple of 2 or 3​
tangare [24]

Answer:

A die is thrown which means that it can land on either 1-6 on the die.So if you want to find the probability of the multiple of 2 or 3....we have multiplies of 2 in the die from 1-6 which is 2,4 and 6 if you count them they are just 3 numbers and since there is a probability of it to land on any of them it will be 3/6 which is 1/2 if yiu divide by 3 to it's lowest term....Then multiple of 3 is 3,and 6.which will be 2/6 which is 1/3 if u cut to its lowest term. Or in the question means addition sign in probability then it is 2 or 3 which is (1/2)+(1/3)=5/6.Thank you for the question
