3 x 1,000 + 7 x 10 + 3 x 1 + 2 x 1 / 100 + 4 x 1,000
3,000 + 70 + 3 + 1/50 + 4,000
7,073 and 1/50
1) c) y = 500 * 2^x
In year 1, x = 1 and the population is 500 * 2^1 = 1000
In year 2, this doubles to 500 * 2^2 = 500 * 4 = 2000
ans so on
This model describes the population doubling every year
2)
A) 3 (1/2)^x and C) (0.25)^x
These numbers reduce as x increases because there is a number with an absolute value less than 1 is being raised to the power of x. They also will never totally reach zero or become negative, but will approach zero as x becomes very large.
Answer:
A
Step-by-step explanation:
We know that it is A because the two smaller angles are being added, and we know the sum is 90 degrees. The only equation that satisfies both of these is A.
Answer:
-5a + 9b
Step-by-step explanation:
- (5a - 9b)
Distribute the minus sign
-5a + 9b
Answer:
6.2, 3 5/7 power of 49, 5
Step-by-step explanation:
6.2 = 31/5
3 5/7 = 26/7
power of 49 = 7/1
5 = 5/1
