If Neptune has 8 and is 2 more than 1/3 the number of Saturn's moons, you would subtract 2 from 8 to get 6, then multiply that by 3 to get 18.

Learning Theory In a typing class,the averege number N of words per minutes typed after t weeks of lessons can be modeled by N =
Jet001 [13]

Answer:

a) N(t=10) = \frac{95}{1+8.5 e^{-0.12(10)}}= \frac{95}{1+ 8.5 e^{-1.2}} = 26.684

b) N(t=20) = \frac{95}{1+8.5 e^{-0.12(20)}}= \frac{95}{1+ 8.5 e^{-2.4}} = 53.639

c) 70 =\frac{95}{1+8.5 e^{-0.12t}}

1+ 8.5 e^{-0.12t} = \frac{95}{70}= \frac{19}{14}

8.5 e^{-0.12t} = \frac{19}{14}-1= \frac{5}{14}

e^{-0.12t} = \frac{\frac{5}{14}}{8.5}= \frac{5}{119}

ln e^{-0.12t} = ln (\frac{5}{119})

-0.12 t = ln(\frac{5}{119})

t = \frac{ln(\frac{5}{119})}{-0.12} = 26.414 weeks

d) If we find the limit when t tend to infinity for the function we have this:

lim_{t \to \infty} \frac{95}{1+8.5 e^{-0.12t}} = 95

So then the number of words per minute have a limit and is 95 as t increases without bound.

Step-by-step explanation:

For this case we have the following expression for the average number of words per minutes typed adter t weeks:

N(t) = \frac{95}{1+8.5 e^{-0.12t}}

Part a

For this case we just need to replace the value of t=10 in order to see what we got:

N(t=10) = \frac{95}{1+8.5 e^{-0.12(10)}}= \frac{95}{1+ 8.5 e^{-1.2}} = 26.684

So the number of words per minute typed after 10 weeks are approximately 27.

Part b

For this case we just need to replace the value of t=20 in order to see what we got:

N(t=20) = \frac{95}{1+8.5 e^{-0.12(20)}}= \frac{95}{1+ 8.5 e^{-2.4}} = 53.639

So the number of words per minute typed after 20 weeks are approximately 54.

Part c

For this case we want to solve the following equation:

70 =\frac{95}{1+8.5 e^{-0.12t}}

And we can rewrite this expression like this:

1+ 8.5 e^{-0.12t} = \frac{95}{70}= \frac{19}{14}

8.5 e^{-0.12t} = \frac{19}{14}-1= \frac{5}{14}

Now we can divide both sides by 8.5 and we got:

e^{-0.12t} = \frac{\frac{5}{14}}{8.5}= \frac{5}{119}

Now we can apply natural log on both sides and we got:

ln e^{-0.12t} = ln (\frac{5}{119})

-0.12 t = ln(\frac{5}{119})

And then if we solve for t we got:

t = \frac{ln(\frac{5}{119})}{-0.12} = 26.414 weeks

And we can see this on the plot 1 attached.

Part d

If we find the limit when t tend to infinity for the function we have this:

lim_{t \to \infty} \frac{95}{1+8.5 e^{-0.12t}} = 95

So then the number of words per minute have a limit and is 95 as t increases without bound.

Points J and K are midpoints of the sides of triangle FGH. What is the value of y?
sashaice [31]
The answer 

the complement of the question is 

What is the value of y?

2
5
7
<span>8
</span>
According to the image, HKJ and FGH are similar, we can apply the theorem of thales
since GK and GF are parallels, so 

HK / HF = HJ / HG = KJ / GF and as we see on the figure, HK = HF /2, this implies  2HK =HF

HK / 2HK =  KJ / GF  it is equivalent to   1/2 = 2y+5 / 5y +3 

likewise, equivalent to  5y +3  = 4y +10, 5y-4y = 10-3, and y = 7


so the answer is 7
