2 tench fish were added. 
in total there are 70 after the 10 added. the probability of getting a carp is 1 half so divide 70 by 2 to see how many carp there are. 70/2 = 35. so right now there are 35 carp and 35 tench. Now, before the 10 were added, there was 60 fish and 27 were carp. So subtract 27 from 60 to know how many tech fish there was. 60 - 27 = 33. There was 33 tech fish and from 33 to 35 goes 2. So 2 tench fish were added.

If IM is reflected across the x-axis and then translated along the vector <4, 1>, in
taurus [48]

Answer:

Final image L"M" will lie in the fourth quadrant.

Step-by-step explanation:

Coordinates of the ends of segment LM,

L  → (-3, 4)

M → (-3, 2)

Rule to reflect a point across x-axis is,

(x, y) → (x, -y)

By this rule, coordinates of the image point of L and M will be,

L(-3, 4) → L'(-3, -4)

M(-3, 2) → M'(-3, -2)

Further these image points are translated along the vector <4, 1>

Rule for this translation will be,

(x, y) → (x + 4, y + 1)

Now the image points of the points L' and M' will be,

L'(-3, -4) → L"(-3 + 4, -4 + 1)

             → L"(1, -3)

M'(-3, -2) → M"(-3 + 4, -2 + 1)

              → M"(1, -1)

Therefore, final image L"M" will lie in the fourth quadrant.

Suppose a student carrying a flu virus returns to an isolated college campus of 2000 students. Determine a differential equation
ad-work [718]

Answer:

x(t) = 2000 - e^(-k*t)

Step-by-step explanation:

Interpretation:

No . infected student = x

Total student = 2000

rate of infected students = dx / dt

not-infected student = 200 - x

The general rate at which student are infected can be expressed as below:

dx / dt = k * ( 2000 - x )

To develop an expression of x(t) we integrate the above expression by separating variables:

dx / (2000 - x ) = k * dt

Now integrate:

\int\limits{\frac{1}{(2000-x)} } \, dx = k *  \int\limits{dt}\\\\- ln (2000-x) = k*t + C\\\\

@ t = 0 , infected students x = 0

Hence,

C = - ln (2000)

- ln (2000-x) = k*t + - ln (2000)\\\\ln (\frac{2000-x}{2000}) = -k*t\\\\ 2000 - x = e^(-kt)\\\\x(t) = 2000 - e ^ (-k*t)

The circumference of a circle is 34 pi. Find the diameter and radius ​
lina2011 [118]

If the circumference is 34 Times PI that means that 34 is the diameter.

So that means that you can just divide the diameter by 2 to get the radius (Because the radius is half of the diameter.)

So the answer is the diameter is 34 and the radius is 17
