The rate at which the total number of bushels of corn currently increases per year depends on the value of "b", which represents the annual increase in yield per acre. If the yield per acre is not increasing (i.e., b = 0), then the rate of increase is a constant 1300 bushels per year.

Let's call the total number of acres the farmer is farming in corn in a given year as "a". We know that initially, a = 100 acres, and that it increases by 30 acres per year. So, in general:

a = 100 + 30t

where "t" is the number of years since the farmer started converting to corn.

Now, let's call the yield in bushels per acre in a given year as "y". We know that initially, y = 130 bushels per acre, and that it increases by "b" bushels per acre per year. So, in general:

y = 130 + bt

Finally, we can calculate the total number of bushels of corn produced in a given year by multiplying the number of acres by the yield per acre:

bushels per year = a * y

Substituting the expressions we have for "a" and "y", we get:

bushels per year = (100 + 30t) * (130 + bt)

Expanding this expression, we get:

bushels per year = 13000 + 1300t + 3900bt + 30tb

Now we can differentiate this expression with respect to time to find how rapidly the total number of bushels of corn currently increases per year:

d(bushels per year)/dt = 1300 + 3900b + 30b

Simplifying, we get:

d(bushels per year)/dt = 1300 + 3930b

So the rate at which the total number of bushels of corn currently increases per year depends on the value of "b", which represents the annual increase in yield per acre. If the yield per acre is not increasing (i.e., b = 0), then the rate of increase is a constant 1300 bushels per year. If the yield per acre is increasing, then the rate of increase will be greater than 1300 bushels per year, and the rate of increase will depend on the value of "b".

There are 4.097 x [tex]10^43[/tex] paths from (0,0) to (90,160) that pass through (80,70).

To calculate the number of paths from (0,0) to (90,160) while passing through (80,70), we need to break down the problem into smaller steps.

First, we can calculate the number of paths from (0,0) to (80,70) and then

multiply that by the number of paths from (80,70) to (90,160).

To go from (0,0) to (80,70), we need to take 80 steps to the right and 70 steps up, which gives us a total of 150 steps. The order in which we take these steps doesn't matter, so we can think of it as choosing 70 steps out of 150 to be up. This can be calculated using the binomial coefficient, which gives us (150 choose 70) = 2.364 x  [tex]10^43[/tex]

To go from (80,70) to (90,160), we need to take 10 steps to the right and 90 steps up, which gives us a total of 100 steps. Using the same method as above, the number of paths from (80,70) to (90,160) is (100 choose 10) = 17,310,309.

Multiplying these two values together, we get the total number of paths from (0,0) to (90,160) that pass through (80,70):

(2.364 x 10^34) x (17,310,309) = 4.097 x  [tex]10^43[/tex]

The derivative of s with respect to t is:

ds/dt = 10(sec² t - tan t) * (tan² t - sec² t)⁴

To find the derivative of s with respect to t, we will use the chain rule and the power rule of differentiation.

Let u = (tan² t - sec² t). Then, s = u⁵.

Using the chain rule, we have:

ds/dt = (du/dt) * (ds/du)

Now, we need to find du/dt and ds/du.

Using the chain rule again, we have:

du/dt = d/dt(tan² t - sec² t) = 2tan t * sec² t - 2sec t * tan t * sec t = 2sec² t * (tan t - sec t)

To find ds/du, we can simply apply the power rule:

ds/du = 5u⁴

Substituting these into the original equation for ds/dt, we get:

ds/dt = (2sec² t * (tan t - sec t)) * (5(tan² t - sec² t)⁴)

Therefore, the derivative of s with respect to t is:

ds/dt = 10(sec² t - tan t) * (tan² t - sec² t)⁴

The equation of the tangent line is y = x - 1.

To find the equation of the tangent line of y=xlog(x) at the point (1,0), we will first need to find the derivative of the function y=xlog(x) with respect to x.

Step 1: Find the derivative of y=xlog(x) with respect to x.
Using the product rule, (uv)' = u'v + uv', where u=x and v=log(x).

u' = derivative of x with respect to x = 1
v' = derivative of log(x) with respect to x = 1/x

Now, apply the product rule:
y' = u'v + uv' = 1*log(x) + x*(1/x) = log(x) + 1

Step 2: Find the slope of the tangent line at the point (1,0).
Evaluate y' at x=1:
y'(1) = log(1) + 1 = 0 + 1 = 1

The slope of the tangent line at (1,0) is 1.

Step 3: Find the equation of the tangent line.
We will use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) is the point (1,0) and m is the slope (1).

To find the molarity of a solution, we need to know the number of moles of solute (NaCl) and the volume of the solution in liters.

First, let's calculate the number of moles of NaCl:

Number of moles of NaCl = Mass of NaCl / Molar mass of NaCl

The molar mass of NaCl is 58.44 g/mol (sodium has a molar mass of 22.99 g/mol and chlorine has a molar mass of 35.45 g/mol).

Number of moles of NaCl = 116.0 g / 58.44 g/mol = 1.985 moles

Next, let's calculate the volume of the solution in liters:

Volume of solution = 2.00 L

Finally, let's calculate the molarity of the solution:

Molarity = Number of moles of solute / Volume of solution

Molarity = 1.985 moles / 2.00 L = 0.9925 M

e is the mathematical constant, approximately 2.71828

r is the growth rate

If the population doubling time is 1 year,

Use the following formula to calculate the growth rate,

The volume of the cone with the same radius and height as the cylinder is 36 cm³.

To find the volume of a cone with the same radius and height as the cylinder, we first need to find the radius and height of the cylinder.

The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.

We are given that the volume of the cylinder is 108 cm^3.

So, 108 = πr^2h

To solve for r and h, we need more information. However, we can use the fact that the cone has the same radius and height as the cylinder to our advantage.

The formula for the volume of a cone is V = (1/3)πr^2h.

Since the cone has the same radius and height as the cylinder, we can substitute the values of r and h from the cylinder into the cone formula.

V = (1/3)π( r^2 )(h)

V = (1/3)π( r^2 )(108/π)

V = (1/3)( r^2 )(108)

V = 36( r^2 )

The cone will hold approximately 198 cubic inches of water. The correct answer is option B.

To find how much water a cone with a diameter of 6 inches and a height of 21 inches will hold, we need to calculate the volume of the cone. We can use the formula for the volume of a cone: V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.

1. Since the diameter is 6 inches, the radius (r) is half of that: r = 6/2 = 3 inches.

2. The height (h) is given as 21 inches.

3. Use 3.14 for π.

Now, plug the values into the formula:

V = (1/3) * 3.14 * (3^2) * 21

4. Calculate the square of the radius: 3^2 = 9

The value of g'(4) is -1/3 if f is a differential function such that f (2) = 4, f(4) = 6, f'(2) = -4, and f'(6) = -3.

First, let's use the information given to find the equation of the tangent line to f at x=2. We know that f(2) = 4 and f'(2) = -4, so the equation of the tangent line at x=2 is

y - 4 = -4(x - 2)

Simplifying, we get

y = -4x + 12

Now let's use the fact that g(x) = f-1(x) for all x. This means that g(f(x)) = x for all x. We want to find g'(4), which is the derivative of g at x=4.

Using the chain rule, we have

g'(4) = [g(f(4))]'

Since f(4) = 6 and g(f(4)) = g(6) (since g(x) = f-1(x)), we can rewrite this as

g'(4) = [g(6)]'

Now we can use the fact that g(x) = f-1(x) to rewrite g(6) as f-1(6)

g'(4) = [f-1(6)]'

Now we need to find the derivative of f-1(x) with respect to x. To do this, we can use the fact that f(f-1(x)) = x for all x. Differentiating both sides with respect to x using the chain rule, we get

f'(f-1(x)) * (f-1)'(x) = 1

Solving for (f-1)'(x), we get

(f-1)'(x) = 1 / f'(f-1(x))

Now we can plug in x=6 and use the information given to find f'(f-1(6)). Since f(4) = 6, we know that f-1(6) = 4. Therefore

f'(f-1(6)) = f'(4)

Using the tangent line equation we found earlier, we know that f(2) = 4 and f'(2) = -4. Therefore, the slope of the line connecting (2,4) and (4,6) is

(6 - 4) / (4 - 2) = 1

Since the line connecting (2,4) and (4,6) is the tangent line to f at x=2, we know that this slope is equal to f'(2). Therefore

f'(4) = f'(f-1(6)) = f'(4)

Now we can plug in x=6 and f'(4) into our expression for (f-1)'(x)

(f-1)'(6) = 1 / f'(4)

Substituting this into our expression for g'(4), we get

g'(4) = [f-1(6)]' = (f-1)'(6) = 1 / f'(4)

Plugging in f'(4) = f'(f-1(6)) = f'(4), we get

g'(4) = 1 / f'(4) = 1 / (-3) = -1/3

Therefore, g'(4) = -1/3.
