<span>y=2(x-3x^2+1) and if it's a multiple choice I'd also choose </span>y=1/2x^2-13x+4
Answer:
D
Step-by-step explanation:
-2 | -8
-1 | -24
0 | -10
1 | 2
2 | 3
Graph D:
point 1. -2 , -8
point 2. -1 , -24
point 3. 0 , -10
point 4. 1 , 2
point 5. 2 , 3
The correct answers are C, D, and E.
1 quart = 32 fl oz
1 pt = 16 oz
Using these conversions you will multiply the number of quarts or pints by the number of ounces in each and then add the totals together to find if they equal 128 oz.
C. 4 x 32 = 128 oz
D. 2 x 32 + 8 x 8 = 128 oz
E. 3 x 32 + 2 x 16 = 128 oz
Therefore, the bones were 6612.5 years old at the time they were discovered.
<h3><u>Half life</u></h3>
Given that the radioactive element carbon-14 has a half-life of 5750 years, and a scientist determined that the bones from a mastodon had lost 57.5% of their carbon-14, to determine how old were the bones at the time they were discovered, the following calculation must be made:
- 50 = 5750
- 100 = 11500
- 57.5 = X
- 57.5 x 11500 / 100 = X
- 6612.5 = X
Therefore, the bones were 6612.5 years old at the time they were discovered.
