$18,000 invested in money market
Step-by-step explanation:
<u>Complete Question:</u>
<em>Jorge invested $28,000 into two accounts. The amount he put in his money market account was $2,000 less than twice what he put into a CD. How much did he invest in each account?</em>
Let money put in CD be x
So
Money put in money market will be 2x - 2000
Alltogether, that is 28,000. Thus, we can write:
x + (2x-2000) = 28,000
Solving, we get:
x + (2x-2000) = 28,000
x + 2x - 2000 = 28,000
3x = 30,000
x = 30,000/3 = 10,000
$10,000 invested in CD
We know 2x - 2000 invested in money market, so:
2(10,000) - 2000 = $18,000 invested in money market
x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer

Step-by-step explanation:
Find the area of the star part:

Subtract the two to find the area of the striped part:
- 190 - 40.5 = 149.5
