The first special case of the chain rule for the composition f o c states that the derivative of f(c(t)) is equal to f'(c(t))c'(t).

For case (a):

(f o c) (t) = f(c(t)) = f(e cos(t)) = e cos(t) sin(t)

Therefore, (f o c)' (t) = f'(c(t))c'(t) = [e cos(t) sin(t)]' (e cos(t))' = e sin(t) cos(t) (e cos(t))' = e cos(t) (-sin(t)) = -e cos2(t)

For case (d):

(f o c) (t) = f(c(t)) = f(t, -t) = t exp(-t)

Therefore,

(f o c)' (t) = f'(c(t))c'(t) = [t exp(-t)]' (t, -t)' = exp(-t) (t, -t)' = exp(-t) (1, -1) = t exp(-t) (-1) = -t exp(-t)

The first special case of the chain rule for the composition f o c states that the derivative of f(c(t)) is equal to the product of f'(c(t)) and c'(t). This means that the derivative of the composition of two functions, f and c, is equal to the product of the derivative of the outermost function and the derivative of the innermost function. To verify this for each case, we need to calculate the derivatives of both f and c, then substitute them into the equation for the derivative of the composition. For example, in case (a), we have (f o c) (t) = f(c(t)) = e cos(t) sin(t). Therefore, (f o c)' (t) = f'(c(t))c'(t) = e sin(t) cos(t) (e cos(t))' = -e cos2(t). Similarly, for case (d), we have (f o c) (t) = f(c(t)) = t exp(-t). Therefore, (f o c)' (t) = f'(c(t))c'(t) = exp(-t) (t, -t)' = -t exp(-t).

The probability of rolling a 3 on the first roll and a 4 on the second roll is 1/36, or approximately 0.028.

This is because the probability of rolling any particular number on a 6-sided number cube is 1/6. Therefore, the probability of rolling a 3 on the first roll is 1/6, and the probability of rolling a 4 on the second roll is also 1/6. Since these events are independent (rolling a 3 on the first roll does not affect the probability of rolling a 4 on the second roll), you can multiply the probabilities of each event to find the probability of both events occurring.

Therefore, the probability of rolling a 3 on the first roll and a 4 on the second roll is (1/6) * (1/6) = 1/36. This can also be written as a decimal as 0.028.

Answer:

To find the inverse of a function, you need to switch the roles of the x and y variables. So the inverse of ƒ(x) = 4x² for x ≤ 0 is written as ƒ^(-1)(y) = ?.

To find the inverse function, we can solve for x in terms of y:

4x² = y

x² = y/4

x = √(y/4)

So the inverse of ƒ(x) = 4x² for x ≤ 0 is ƒ^(-1)(y) = √(y/4). Note that this inverse function is only defined for y ≤ 0, since the original function is only defined for x ≤ 0.

Step-by-step explanation:

First, let us find the circumference of the wheel ( circle ) using the below formula.

C = 2πr

Here,

r ⇒ radius ⇒ 28 cm

Let us solve it now.

C = 2 × π × 28

C = 175.93 cm

And now let us covert the travelling distance to centimeters.

( For that, multiply km by 100000 )

3.52km = 352000 cm

Now, to find the number of revolution, divide the total distance travelled by its circumference.

352000/175.93 = 2000.79

Approximately, 2001 revolutions

The number of revolutions made by a wheel of 28cm radius covering a distance of 3.52km is 2000.8.

Given,

Radius, r = 28cm

Circumference = 2πr = 56π cm

Circumference = Distance traveled in one revolution

The distance traveled by wheel = 3.52km = 3520m = 352000cm

Let N = number of revolution

Now we know that,

Total distance = Number of revolutions × 1 revolution distance(circumference)

or 352000 = N × 56π

or N = 352000/56π

or N = 2000.8

Therefore, the number of revolutions made by a wheel of 28cm radius covering a distance of 3.52km is 2000.8.

Explanation:

Method 1

The exterior angles of any polygon always add to 360 degrees.

3x+8x+9x = 360

20x = 360

x = 360/20

x = 18

Then,

which represent the exterior angles of this triangle.

As a check: 54+144+162 = 360 which confirms we have the correct values.

The smallest exterior angle is therefore 54 degrees

---------------------

Method 2

The exterior angles 3x, 8x, and 9x have the corresponding interior angles of 180-3x, 180-8x, and 180-9x in that order.

For any triangle, the interior angles always add to 180 degrees.

angle1+angle2+angle3 = 180

(180-3x)+(180-8x)+(180-9x) = 180

540-20x = 180

-20x = 180-540

-20x = -360

x = -360/(-20)

x = 18

This then leads to 3x = 3*18 = 54 degrees as the final answer.

From the given data about population, we found out answers:

a) The percentage of the panels that will be scrapped is 4.55%.

b) The percentage of the panels that will need rework is 45.45%.

c) In order to reduce the scrap percentage to 1%, the manufacturer must re-center the process with a new mean value of 10.50 mm.

d) The rework percentage with the new mean value is 0.33%.

This is because the new mean value (10.60 mm) is within the specified range (10.50 +0.50 mm). Thus, there will be no rework or scraped panels due to the mean being outside of the specified limits.

The triangle's angle sum property states that the sum of its angles can equal 180 degrees. Since a triangle has three sides, each of its vertices has an angle. Regardless of whether a triangle is acute, obtuse, or right-angled, its interior angles always sum to 180 degrees.

The triangle's angle sum property is one of the geometry's most frequently used properties. The main application of this property is in the calculation of the unknown angles. The angle sum property is used to calculate the measure of an unknown interior angle when the values of the other two angles are known.

Here,

Given that

Let the angles be y, z and x

y = 80°

z = 40°

x = ?

Using the angle sum property

Sum of the interior angle of a triangle = 180°

x + y + z = 180°

x + 80 + 40 = 180

x + 120 = 180

x = 180 - 120

Part 1: A = 0, B = 2, C = 3, D = 0, E = -2

Part 2: The derivative f'(3) is 6.

Part 3: The equation of the tangent line to the curve y = f(x) at x = 3 is y = 6x – 15.

This equation of the tangent line can be found by substituting x = 3 into the simplified difference quotient expression C + Dh + Eh2 , and then taking the limit as h approaches 0.

This expression can then be rearranged to give the equation of the line, which is y = 6x – 15. The equation of the tangent line gives the slope of the line at the given point, in this case x = 3. The slope of the line is 6, which is the same as the derivative of the function at the given point.

P(x) = 4000-8x

First we need to find revenue function

R(x) = x.P(x) = x(4000-8x) = 4000x-8x^2

Now, we need to find marginal revenue

R'(x) = d/dx (4000x-8x^2) = 4000-16x

C'(x) = d/dx (12000+4000x-3.8x^2=0.004x^3) = 400-7.6x+0.012x^2

for maximum profit,

C'(x) = R'(x)

The equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2) is y = -2x - 18.

Therefore, the answer is b) y = −2x − 18.

The slope-intercept form of a line's equation is y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To find the equation of a line that is perpendicular to another line, we can use the fact that the slopes of perpendicular lines are negative reciprocals of each other. This means that if the slope of one line is m, the slope of a line perpendicular to it is -1/m.

The equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2) can be found by first finding the slope of the line 2x – 4y = 17. We can do this by rearranging the equation to the slope-intercept form:

2x – 4y = 17

-4y = -2x + 17

y = (1/2)x - (17/4)

The slope of the line 2x – 4y = 17 is (1/2). Therefore, the slope of a line perpendicular to it is -2.

To find the equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2), we can use the slope-intercept form of a line's equation and plug in the slope (-2) and the coordinates of the point p(-8, -2):

You must discover the point at which the total cost of each process is equal in order to identify the crossover point between processes a and b. The sum of the fixed cost and the variable cost per unit, multiplied by the number of units, is the cost of process A as a whole. The sum of the fixed cost and the variable cost per unit, multiplied by the quantity of units, is the cost of process b as a whole.

 You can make the overall cost of each process equal to one another and solve for the number of units to determine the crossover point.

  When x is the number of units, the total cost of process an is equal to $1000 + (5 * x).

Process B has a total cost of $500 plus (7.50 * x), where x is the number of units.

When we equalize  these two expressions, we obtain:

$1000 + (5 * x) = $500 + (7.50 * x)
