According to Euclidean geometry, a square is an equilateral quadrilateral having four equal sides and four equal angles. It is often referred to as a rectangle with two nearby sides of equal length. A square is an equilateral quadrilateral because it has four equal sides and four equal angles. Square angles are 90-degree or straight angles. Also, the diagonals of the square are evenly spaced and divide at a 90-degree angle. an adjacent rectangle with two equal sides. a quadrilateral with four equal-length sides and four right angles. A parallelogram with two adjacent, equal sides forming a right angle. A rhombus with straight sides.

To determine the answer, multiply the areas of the shaded squares by the overall area of the figure.

Assuming that both squares are the same size, we may combine the fractions using a common denominator:

2/12 + 2/15 = 5/60 + 4/60 = 9/60 = 3/20

As a result, the entire shaded area is 3/20 of the total area of the diagram.

We can't discover the exact area of the graphic because it's not presented. As a result, we can only represent the answer in fractions or decimals.

In decimal form, the answer is 0.15, which is close to option A, 0.148. As a result, the answer is A. 0.148.

1. The additional cost incurred when production is increased from 2 units to 15 units given marginal cost function is approximately $992.68.

2. When production is increased to 15 units, the total cost C(15) is approximately $1,259.68.

To find the additional cost incurred when production is increased from 2 units to 15 units, we need to calculate the integral of the marginal cost function over that interval.

C'(x) = 0.12x^2 - 4x + 100

We'll integrate C'(x) from 2 to 15:

∫(0.12x^2 - 4x + 100) dx from 2 to 15

First, find the antiderivative of C'(x):

C(x) = (1/3)(0.12x^3) - (1/2)(4x^2) + 100x + k

C(x) = 0.04x^3 - 2x^2 + 100x + k

Now, calculate the additional cost incurred from 2 units to 15 units:

C(15) - C(2) = [0.04(15)^3 - 2(15)^2 + 100(15)] - [0.04(2)^3 - 2(2)^2 + 100(2)]

C(15) - C(2) = [0.04(3375) - 2(225) + 1500] - [0.04(8) - 2(4) + 200]

C(15) - C(2) = [135 - 450 + 1500] - [0.32 - 8 + 200]

C(15) - C(2) = 1185 - 192.32

C(15) - C(2) = 992.68

We are given that C(2) = 267. To determine C(15), we can use the additional cost we calculated in part (a):

C(15) = C(2) + (C(15) - C(2))

C(15) = 267 + 992.68

C(15) = 1259.68

Answer:

x=(11/4)y or

y=(4/11)x

Step-by-step explanation:

There is one solution for the system of equations.

We have,

The two lines can be represented as:

Line 1: y = -x + 3

Line 2: y = (2/3)x + 3

To find the number of solutions for the system of equations represented by these lines, we need to find where they intersect on the coordinate plane.

This is because the point of intersection is a solution that satisfies both equations simultaneously.

We can solve for x by setting the two equations equal to each other:

-x + 3 = (2/3)x + 3

Simplifying this equation, we get:

(5/3)x = 0

x = 0

Now we can find the corresponding y-coordinate by plugging x = 0 into either of the two equations:

For Line 1, y = -x + 3 = -0 + 3 = 3

For Line 2, y = (2/3)x + 3 = (2/3)(0) + 3 = 3

Now,

The two lines intersect at point (0,3), which is the only solution that satisfies both equations.

There is one solution for the system of equations.

According to the Central Limit Theorem, the sampling distribution of sample means would have a mean of 5.4 years.

Step-by-step explanation:

For a normally distributed random variable X, with mean and standard deviation, the sampling distribution of sample means with size n can be approximated to a normal distribution with mean and standard deviation.

As long as n is at least 30, the Central Limit Theorem can also be applied to skewed variables.

We have the following problem:

Answer:

Step-by-step explanation:

The mean of the sampling distribution of sample means can be calculated using the formula:

μM = μ

where μ is the population mean and M is the sample mean.

Thus, μM = μ = 5.4 years.

Therefore, the mean of the sampling distribution of sample means would also be 5.4 years.

The two options that represent circles with a diameter of 12 units and a center on the y-axis are:

(x - 0)² + (y - 0)² = 6², which simplifies to x² + y² = 36

(x - 0)² + (y - 12)² = 6², which simplifies to x² + (y - 12)² = 36

What is circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.

A circle with a diameter of 12 units and a center on the y-axis will have the equation of the form x² + (y - k)² = r², where k is the y-coordinate of the center and r is the radius of the circle.

The y-coordinate of the center is on the y-axis, so it is 0.

The radius of the circle is half of the diameter, which is 6 units.

Substituting these values in the general equation, we get x² + y² = 36.

Therefore, the equations that represent circles with a diameter of 12 units and a center on the y-axis are:

(x - 0)² + (y - 0)² = 6², which simplifies to x² + y² = 36

(x - 0)² + (y - 12)² = 6², which simplifies to x² + (y - 12)² = 36

So, the options that represent these equations are:

x² + (y – 3)2 = 36

(x – 4)² + y² = 36

x2 + (y + 8)2 = 36

Therefore, the two options that represent circles with a diameter of 12 units and a center on the y-axis are:

(x - 0)² + (y - 0)² = 6², which simplifies to x² + y² = 36

(x - 0)² + (y - 12)² = 6², which simplifies to x² + (y - 12)² = 36.

t = (47.2 - 38.6) / √((9²/26) + (9.3²/20))

t = 2.77

Degrees of Freedom:

df = {(s₁²/n₁ + s₂²/n₂)² } / {(s₁²/n₁)²/(n₁-1) + (s₂²/n₂)²/(n₂-1)}

Calculating the degrees of freedom:

df = ((9²/26) + (9.3²/20))² / (((9²/26)²/25) + ((9.3²/20)²/19))

df = 42.38 (rounded to nearest integer) = 42

Using a t-distribution table or calculator with 42 degrees of freedom and a one-tailed test at α = 0.01, we get a critical value of 2.423.

A service is composed of numerous distinctive components that cooperate to create distinctive results for each input.

Here,

The average rate of change of g(t) across the range -3 to 1 must be determined.

To accomplish this, we must determine the change in g(t) across the period and divide it by the interval's duration.

=> g(-3) = -3666 at time t=3, and g(1) = 0 at time t=1. As a result, the interval's change in g(t) is:

=> g(1) - g(-3) = 0 - (-3666) = 3666

The interval is the following length:

=> 1 - (-3) = 4

Consequently, g(t)'s average rate of change over the range -3 to 1 is:

=> (3666) / (4) = 916.5

Consequently, 916.5 is the precise value of the average rate of change of g(t) over the range -3 t 1.

The evaluation of the sinusoidal function for the blood pressure of the individual indicates that the period, maximum and minimum blood pressure and the times are;

(a) 1/60 minutes

(b) Maximum (systolic) blood pressure = 110 mmHg

Minimum (diastolic) blood pressure = 50 mmHg

(c) The times are; n/60 + 1/240

A sinusoidal function is a periodic function based on the sine or cosine of an angle.

The specified function can be presented as follows;

p(t) = 80 + 30·sin(120·pi·t)

(a) The function is a sinusoidal function of the form; y = A·sin(B·(x - C)) + D

Where;

A = The amplitude

B = 2·π/Period

C = The phase shift

D = The vertical shift

Comparing, we get;

C = 0, D = 80, x = t

Therefore;

y = A·sin(B·(t)) + 80

B = 120·π

The period = 2·π/(120·π) = 1/60

(b) The maximum and minimum values are obtained when sin(120·pi·t) = ±1 as follows;

Maximum value = pmax = 80 + 1 × 30 = 110

Minimum value = pmin = 80 - 1 × 30 = 50

The systolic or maximum blood pressure = 110 mmHg

The diastolic or minimum blood pressure = 50 mmHg

(c) When the blood pressure is maximum, we get;

p(t) = 80 + 30·sin(120·pi·t) = 110

80 + 30·sin(120·pi·t) = 110

sin(120·pi·t) = (110 - 80)/30 = 1

120·pi·t = arcsine(1) = pi/2 + 2·n·pi

120·t = 1/2 + 2·n

We need to work out v1 and v2.

The formula for time is equal to distance over speed. t=s/v

Because the two ships are colliding, the formula will be t=s/v1+v2

Plug in given values:

8h=400mi/x+x+20

8h=400mi/2x+20

Cross multiply:
