Answer:
402 days.
Step-by-step explanation:
f(x)=1+1.5ln(x+1)
When f() = 10 we have:
10 = 1 + 1.5ln (x + 1)
ln (x + 1) = (10-1) / 1.5 = 6
x + 1 = e^6
x = e^6 - 1 = 402.4.
Answer:
v=48
Step-by-step explanation:
If you are moving the center of circle 2 to the the center of circle 1, then the translation rule is (x,y) ---> (x+4, y+10).
Note how x = 1 turns into x = 5. So we add 4
Also, y = -2 turns into y = 8. We add 10
The scale factor to turn the radius r = 4 into r = 8 is 2. Basically we double the radius. We can divide the two radii to see 8/4 = 2
----------------------------------
Summary:
To go from circle 2 to circle 1, we apply these two transformations
translation: (x,y) ---> (x+4, y+10)
dilation: scale factor 2
note:
if you want to go backwards, go from circle 1 to circle 2, then undo the transformations above
The formula of a midpoint:
We have:
Substitute
<h3>Answer: (-2, -4)</h3>
