Step-by-step explanation:
Answer:
4.1 gallons per person
Step-by-step explanation:
The total consumption of fruit juice is 2.05 billion
The total population is 500 million
Therefore the average number of gallons fruit juice consumed per person can be calculated as follows
=total consumption/total population
= 2,050,000,000/500,000,000
= 4.1 gallons per person
Answer: Choice A) -312,500
=====================================
The long way to find the answer is to multiply each term by -5 until you've generated 8 terms total.
4 is the first term
-20 is the second term (4 times -5 = -20)
100 is the third term (-20 times -5 = 100)
100 times -5 = -500 which is the fourth term
-500 times -5 = 2500 which is the fifth term
2500 times -5 = -12500 which is the sixth term
-12500 times -5 = 62500 which is the seventh term
62500 times -5 = -312500 which is the eigth term
---------------------
A shortcut is to use the formula below
a(n) = a*(r)^(n-1)
Plug in a = 4, r = -5 and n = 8
a(n) = a*(r)^(n-1)
a(8) = 4*(-5)^(8-1)
a(8) = 4*(-5)^7
a(8) = 4*(-78125)
a(8) = -312,500
and we get the same answer
Answer:
2sqrt(5)+11
Step-by-step explanation:
f(x)=sqrt(x)+11
f(20)=sqrt(20)+11
f(20)=sqrt(4*5)+11
f(20)=sqrt(4)*sqrt(5)+11
f(20)=2*sqrt(5)+11
