The marginal profit at a production level of 40 items is 2064.

To find the marginal profit at a production level of 40 items, we need to first find the marginal cost and marginal revenue at this production level. The marginal cost and marginal revenue are the derivatives of the cost and revenue functions, respectively.

The marginal cost function is:
C'(q) = 3q^2 - 22q + 56

The marginal revenue function is:
R'(q) = -6q + 2600

At a production level of 40 items, the marginal cost is:
C'(40) = 3(40)^2 - 22(40) + 56 = 296

The marginal revenue at this production level is:
R'(40) = -6(40) + 2600 = 2360

The marginal profit is the difference between the marginal revenue and marginal cost:
Marginal profit = 2360 - 296 = 2064

Therefore, the marginal profit at a production level of 40 items is 2064.

Step-by-step explanation: I belive that is the answer

Answer:

We can simplify this expression by using the formula (a + b)(a - b) = a^2 - b^2:

(1 + √10)(1 - √10) = 1^2 - (√10)^2 = 1 - 10 = -9

Therefore,

(1 + √10)(1 - √10) = -9

Now we can multiply by 2:

2(1 + √10)(1 - √10) = 2(-9)

2(1 - 10) = -18

So the final result is -18.

The equation of the perpendicular bisector of the line segment with endpoints (1,6) and (-9,-2) is y = (-5/4)x - 3.

Any location on the perpendicular bisector is equally spaced from the line segment's terminal points, according to the perpendicular bisector theorem.

These procedures must be taken in order to determine the equation of a line segment's perpendicular bisector:

Determine the line segment's midway.

Determine the line segment's slope.

In order to determine the slope of the perpendicular bisector, calculate the negative reciprocal of the slope.

To determine the equation of the perpendicular bisector, use a line's point-slope form.

These procedures allow us to determine the equation for the perpendicular bisector of the line segment with ends (1, 6) and (-9, -2), which is as follows:

Midpoint: The midpoint of the line segment can be found by taking the average of the x-coordinates and the average of the y-coordinates:

Midpoint = ((1 + (-9))/2, (6 + (-2))/2)

= (-4, 2)

Slope: The slope of the line segment can be found using the formula:

slope = (change in y) / (change in x)

slope = (6 - (-2)) / (1 - (-9))

= 8/10

= 4/5

Negative reciprocal: The slope of the perpendicular bisector is the negative reciprocal of the slope of the line segment:

slope of perpendicular bisector = -1 / slope

= -1 / (4/5)

= -5/4

Equation: We can now use the point-slope form of a line to find the equation of the perpendicular bisector. We will use the midpoint of the line segment as the point on the line:

y - y1 = m(x - x1)

where m is the slope of the perpendicular bisector, and (x1, y1) is the midpoint of the line segment. Substituting the values we found, we get:

y - 2 = (-5/4)(x + 4)

Simplifying, we can write the equation in slope-intercept form:

y = (-5/4)x - 3

Hence, the equation of the perpendicular bisector of the line segment with endpoints (1,6) and (-9,-2) is y = (-5/4)x - 3.

Answer:

<HDG = 39°

Step-by-step explanation:

Red square is a right angle which mean its a 90°

Those two angle <CDG and <HDG are complementary angle which mean they both add up to 90°

<CDG + <HDG = 90°

51° + (3t+15)° = 90°

Solve for t.

3t + 51 + 15 = 90°

3t + 66 = 90°

3t = 24

t = 8

Plug t = 8 into <HDG to find the measurement.

<HDG = 3t + 15

<HDG = 3*8 + 15

<HDG = 24 + 15

<HDG = 39°

Starting with a $500 investment, you would have approximately $6,795.70 after 40 years if the investment increases exponentially by about 15% every 2 years.

Algebraic expression can be defined as combination of variables and constants.

To find the future amount of the investment after 40 years, we can use the formula for compound interest:

Future Amount = Present Value x (1 + Interest Rate/Compounding Frequency)^(Compounding Frequency x Time)

In this case, the present value (PV) is $500, the interest rate (r) is 15%,

the compounding frequency (n) is 1 (since the interest is compounded every 2 years).

The time (t) is 40 years.

Plugging in the values, we get:

Future Amount = [tex]500 \times (1 + 0.15/1)^{(1 \times 40/2)}[/tex]

Future Amount = [tex]500 \times (1.15)^{20}[/tex]

Future Amount = [tex]500 \times 13.591409[/tex]

Future Amount = $6,795.70 (rounded to the nearest cent)

Therefore, starting with a $500 investment, you would have approximately $6,795.70 after 40 years if the investment increases exponentially by about 15% every 2 years.

The volume of the cone is approximately 94.25π cubic cm.

To find the volume of a cone, we use the formula V = 1/3πr²h, where V is the volume, r is the radius of the base, and h is the height or depth of the cone. In this case, we know that the depth of the cone is 14 cm and the base radius is 9/2 cm.

First, we need to calculate the radius of the base in terms of cm, since the formula requires it. We are given that the base radius is 9/2 cm, so we can substitute this value for r:

r = 9/2 cm

Next, we need to calculate the volume of the cone using the formula. We know that the depth of the cone is 14 cm, so we can substitute this value for h:

V = 1/3πr²h

V = 1/3π(9/2)²(14)

V = 1/3π(81/4)(14)

V = 1/3π(1134/4)

V = 1/3π(283.5)

Answer:

Step-by-step explanation:

The Rational Roots Theorem states that the possible rational roots of a polynomial equation are the factors of the constant term divided by the factors of the leading coefficient. Therefore, the possible rational roots of P(x) are ±1, ±2, ±4, and ±4.

To find the exact roots of P(x), we can use synthetic division. Synthetic division is an efficient way of dividing a polynomial by a number. Using this method, we can determine that there are three roots for P(x): 1, -2, and -3. To verify this, we can evaluate P(x) for each of the three roots and confirm that the result is zero.

We can also use the quadratic formula to find the remaining two roots. Since P(x) is a 5th degree polynomial, the two remaining roots are complex and can be found using the quadratic formula. The complex roots of P(x) are -0.5 ± 0.5i.

In conclusion, the roots of P(x) are 1, -2, -3, -0.5 ± 0.5i. All of these results can be verified by evaluating P(x) and confirming that the result is zero.

If F(-9,-4), E(-7, a) G(-2,5), and H(-6,-1) then the value of a is equal to -1, then EF is parallel to GH.

What are the parallel lines?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

To determine if EF is parallel to GH, we need to compare the slopes of the two lines.

The slope of line EF can be found using the coordinates of points E and F:

slope of EF = (y2 - y1)/(x2 - x1) = (a - (-4))/(-7 - (-9)) = (a + 4)/2

The slope of line GH can be found using the coordinates of points G and H:

slope of GH = (y2 - y1)/(x2 - x1) = (5 - (-1))/(-2 - (-6)) = 6/4 = 3/2

For EF to be parallel to GH, their slopes must be equal. Therefore, we can set the slope of EF equal to the slope of GH and solve for a:

(a + 4)/2 = 3/2

Multiplying both sides by 2, we get:

a + 4 = 3

Subtracting 4 from both sides, we get:

a = -1

Therefore, if a is equal to -1, then EF is parallel to GH.
