Answer:
The world's population is 23 times larger than the United States population.
Step-by-step explanation:
United States population = 3x10^8=300,000,000 or 300 million
The World's population = 7x 10^9= 7,000,000,000 or 7 billion
7 billion divided by 300 million = 23.33333333
7000000000 / 300000000 = 23.333333333
Direct variation problems use the equation y = kx
Replace y and X with the two known numbers to solve for k:
6=k9
Solve for K by dividing both sides by 9:
k = 6/9, reduces to 2/3
Now replace y and k into the formula to solve for x:
15 = 2/3x
Solve for X by dividing both sides by 2/3:
X = 15 / 2/3
X = 45/2 as an improper fraction, 22 1/2 as a proper fraction or 22.5 as a decimal.
Not sure which format the answer needs to be in, so I gave all three.
Answer:
Neither
Step-by-step explanation:
f(x) = 6x^2 + 5x.
If a function is even them f(x) = f(-x), so here we have:
f(-x) = 6(-x)^2 + 5(-x)
= 6x^2 - 5x so it is not even.
If it is odd then -f(x) = f(-x) so:
- f(x) = - 6x^2 - 5x which is not equal to f(-x) so it is neither.
There is no question therefore I cannot answer
