Answer:
ok so anything raised to the power 0 is equal to 1 so we'll take 9x^0 =1 and then let's solve
Step-by-step explanation:
3x^2(9x)^0
3x^2(1)
=3x^2
Answer:
Option B is correct, i.e. 30 ways.
Step-by-step explanation:
Given that there are 6 runners at a competition. So it means n = 6.
It says 2 medals are awarded for first and second place. So it means r = 2.
Each medal is different, it means the order matters here. It is the case of Permutations, so we will use nPr formula.
Total number of ways = 6P2 = 6x5 = 30.
Hence, option B is correct, i.e. 30 ways.

Answer: 2.2464 × 10^8
Step-by-step explanation:
Percentage of obese Americans in 2011 - 2012 = 35%
Percentage of Americans who are adult = 72%
United States population estimate = 312 million
Adult = age 20 and above
Number of adult Americans (age 20 and above) :
72% of the total united states estimated population
72% of 312,000,000
72/100 × 312,000,000
0.72 × 312,000,000
= 224,640,000
Hence, estimated Adult American population (age 20 and above) = 224,640,000
2.2464 × 10^8
A) 20x^2 + 8x
b) 5x^2 - 50x
