Answer:
25.5 years
Step-by-step explanation:
The multiplier for continuous compounding at annual rate r for t years is ...
e^(rt)
You want the value of t when that is 3 and r=0.043.
3 = e^(0.043t)
ln(3) = 0.043t
t = ln(3)/0.043 ≈ 25.549 . . . . years
Answer:
x = 3.75
Step-by-step explanation:
Replace y with the y equation.
So..
4x - 2(x + 1.75) = 4
Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
Answer:
(B)Enlarge by scale factor of 3 about the origin. Then translate 1 right.
Step-by-step explanation:
For the end point (3,4)
- If we enlarge (3,4) by a scale factor of 3 about the origin, we have: (9,12)
- If we then translate 1 right, we have :(10,12)
Similarly for the end point (4,5):
- If we enlarge (4,5) by a scale factor of 3 about the origin, we have: (12,15)
- If we then translate 1 right, we have :(13,15)
The correct option is B.
