Answer:
m(x) = 20000(0.97)^x
Step-by-step explanation:
Given that :
Initial population, population in 1990, P = 20,000
Rate, r = 3% = 0.03
Number of visitors to the museum x years after 1990
Since population decreases, Decay formula
m(x) = Initial population * (1 - r)^x
m(x) = 20000(1 - 0.03)^x
m(x) = 20000(0.97)^x
Answer:
24m^2, I think.
Step-by-step explanation:
Well the area is Base times Height, so 6 times 4, the squared is just showing that its the area.
Answer:
1/2
Step-by-step explanation:
We assume your "a quarters" is a poor speech-to-text rendering of "eight quarters." If so, Selena has 16 coins, of which 8 are not quarters. The probability of choosing a "not quarter" is ...
8/16 = 1/2 = p(not quarter)
Harvey would need to multiply the first equation by -2 and the second equation by 7.
You can tell this by looking for the least common multiple of each x coefficient. Below are the multiples of both numbers.
7: 7, 14, 21, 28, 35, 42
2: 2, 4, 6, 8, 10, 12, 14, 16, 18
You'll notice that the first number to appear in both lists is 14. So we must multiply so that one x is 14 and the other is -14. To do this, we know we must multiply 7 by -2 and 2 by 7. This will give us the desired result. You can solve for y after that.
