Step-by-step explanation:

From the circle it can be seen that the angle ∠EQD lies on the circumference of the circle. A circumference of a circle is known to be any point on the circle. Also we have central angle ∠ECD of 104°

In circle geometry, there is a theorem that states; Angle at the center of a circle is twice the angle at the circumference. Applying this theorem to the given question we can say, ∠ECD = 2∠EQD

Substituting the given value;

104° = 2∠EQD

Dividing both sides by 2

104/2 = 2∠EQD/2

∠EQD = 104/2

∠EQD = 72°

Answer: The answer is 52.

Step-by-step explanation:

To achieve an anticipated production of 250 cars per 8-hour day, Fast Lube would need a minimum of 47 service bays (rounded up to the next whole number).

The effective capacity of a service bay is the maximum number of cars it can serve per hour, taking into account the efficiency. In this case, the effective capacity is 5.5 cars per hour.

To determine the number of service bays needed, we divide the anticipated production (250 cars) by the effective capacity (5.5 cars per hour) to find the number of hours required.

250 cars / 5.5 cars per hour = 45.45 hours

Since Fast Lube operates for 8 hours per day, we divide the total hours required by the operating hours to find the number of service bays needed.

45.45 hours / 8 hours per day = 5.68 service bays

Since we need to round up to the next whole number, Fast Lube would need a minimum of 47 service bays to achieve the anticipated production of 250 cars per 8-hour day.

The minimum percentage of stores in Mooville that sell a gallon of milk for between 33.41 and 54.01 is approximately 87.23% .To find the minimum percentage of stores in Mooville that sell a gallon of milk for between 33.41 and 54.01, we can use the concept of the empirical rule for normally distributed data.

According to the empirical rule, for a normal distribution:

- Approximately 68% of the data falls within one standard deviation of the mean.

- Approximately 95% of the data falls within two standard deviations of the mean.

- Approximately 99.7% of the data falls within three standard deviations of the mean.

Since we don't have specific information about the distribution of milk prices, we can assume a normal distribution for this calculation.

First, we need to determine the number of standard deviations away from the mean each price is:

z1 = (33.41 - 53.71) / 50.19

z2 = (54.01 - 53.71) / 50.19

Then, we can calculate the percentage of stores within this range using the empirical rule:

Percentage = (68% + 95% + 99.7%) / 3

Substituting the values and calculating:

Percentage = (68% + 95% + 99.7%) / 3 ≈ 87.23%

Therefore, the minimum percentage of stores in Mooville that sell a gallon of milk for between 33.41 and 54.01 is approximately 87.23%.

We are asked to prove the inequality L(f, S) ≤ L(f, P) ≤ U(f, P) ≤ U(f, S) for a bounded function f on an interval [a, b], where S and P are partitions of the interval.

To prove the inequality, we start by considering the lower sums. The lower sum L(f, S) is defined as the sum of the infimum values of f over each subinterval of the partition S. Since the partition P is a refinement of S, each subinterval of S is contained within a subinterval of P. Therefore, the infimum value of f over each subinterval in S will be less than or equal to the infimum value over the corresponding subinterval in P. This implies that L(f, S) ≤ L(f, P).

Next, we consider the upper sums. The upper sum U(f, S) is defined as the sum of the supremum values of f over each subinterval of the partition S. Again, since P is a refinement of S, each subinterval in S is contained within a subinterval in P. Thus, the supremum value of f over each subinterval in S will be greater than or equal to the supremum value over the corresponding subinterval in P. Therefore, U(f, S) ≥ U(f, P).

Combining the results, we have L(f, S) ≤ L(f, P) and U(f, P) ≤ U(f, S). This establishes the desired inequality L(f, S) ≤ L(f, P) ≤ U(f, P) ≤ U(f, S), proving the statement.

The height at which we should make the cut from the base is 30 - 3 √10 cm.

First, we can find the height of the right cone using the Pythagorean theorem:

h = √(r² + l²)

where h is the height, r is the radius of the base, and l is the slant height. Since the slant height is equal to the height, we have:

h = √(10² + 30²)

h = √100 + 900

h = √1000

h = 10 √10

To find the height at which we should cut the cone, we can use the ratio of the radii of the two cones:

(large cone radius) / (large cone height) = (small cone radius) / (truncated cone height)

10 / (10√(10)) = 3 / (truncated cone height)

truncated cone height = (10 √10 x 3) / 10 = 3 √10 cm

Therefore, the height at which we should make the cut from the base is 30 - 3 √10 cm.

Answer:

roots are real and distinct

Step-by-step explanation:

To determine the nature of the roots use the discriminant , b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then roots are not real

Given

2x² - \(\sqrt{5}\) x - 2 = 0

with a = 2, b = - \(\sqrt{5}\) , c = - 2 , then

b² - 4ac

= (- \(\sqrt{5}\) )² - ( 4 × 2 × - 2)

= 5 - (- 16)

= 5 + 16

= 21

Since b² - 4ac > 0 then the equation has 2 real and distinct roots

Answer:20 feet by 10 feet

Step-by-step explanation:

The percent difference in si for an object located at so = 10f and so = [infinity] can be calculated using the formula:

Percent Difference = ((si - so) / so) * 100%

For so = 10f and so = [infinity], let's calculate the percent difference in si:

1. For so = 10f:
  - Suppose the image distance si is 2f.
  - Using the formula, the percent difference can be calculated as follows:
    ((2f - 10f) / 10f) * 100% = (-8f / 10f) * 100% = -80%

  Therefore, the percent difference in si for an object located at so = 10f is -80%.

2. For so = [infinity]:
  - When the object is located at "optical infinity" (so = [infinity]), the image distance si becomes equal to the focal length of the lens.
  - If the lens is converging, the image distance si would be positive and equal to the focal length (si = f).
  - If the lens is diverging, the image distance si would be negative and equal to the focal length (si = -f).

  Therefore, when the object is located at "optical infinity," the image distance si will be equal to the focal length of the lens.

Now let's consider so = 100f and so = [infinity]:

1. For so = 100f:
  - Suppose the image distance si is 2f.
  - Using the formula, the percent difference can be calculated as follows:
    ((2f - 100f) / 100f) * 100% = (-98f / 100f) * 100% = -98%

  Therefore, the percent difference in si for an object located at so = 100f is -98%.

2. For so = [infinity]:
  - As mentioned earlier, when the object is located at "optical infinity" (so = [infinity]), the image distance si will be equal to the focal length of the lens.

So, the percent difference in si for an object located at so = [infinity] will always be 0%.

It is justified to consider an object to be located at "optical infinity" when the object is at a very far distance from the lens, where the rays of light can be approximated as parallel. In such cases, the image distance si becomes equal to the focal length of the lens, resulting in clear and focused images. This assumption simplifies calculations and analysis in optics.

A sequence of transformation that would move ΔABC onto ΔDEF is: D. a dilation by a scale factor of 1/2, centered at the origin, followed by a 90° clockwise rotation about the origin.

In Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

In this scenario an exercise, we would dilate the coordinates of the pre-image by applying a scale factor of 1/2 that is centered at the origin as follows:

Ordered pair B (-4, 2) → Ordered pair B' (-4 × 1/2, 2 × 1/2) = Ordered pair B' (-2, 1).

In Mathematics and Geometry, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction;

(x, y)                               →            (y, -x)

The answer is 0.00068 m³.

Density = Final Density/ (1 - Shrinkage)

Therefore, the Final density of the gear = Density x (1 - Shrinkage)

The final density of the gear = 6.5 x 10^3 kg/m^3 x 0.95 = 6175 kg/m^3

Let V be the volume of the gear, and ρ be the density of the powder.

Then, Mass of the gear = Volume x Density

Mass of the gear = V x ρFinal mass of the gear = Mass of the gear / (1 - Shrinkage)

Final mass of the gear = V x ρ / (1 - Shrinkage)

Density of the gear = Final mass of the gear / Final volume of the gear

The density of the gear = (V x ρ / (1 - Shrinkage)) / (V / (1 - Shrinkage))

Density of the gear = ρ

Therefore,ρ = Final density of the gear = 6175 kg/m³

Hence,Volume of the gear = Mass of the gear / Density of the powderVolume of the gear = 0.91 kg / 6.5 x 10³ kg/m³Volume of the gear = 0.00014 m³

Let Vp be the volume of the powder.

Then,Volume of the powder = Vp - Volume of the gearVolume of the powder = Vp - 0.00014 m³

Also, the mass of the powder is given as: Mass of the powder = Volume of the powder x Density of the powder

Mass of the powder = Vp ρ

Hence, the required volume of powder to make the gear is (Vp - 0.00014 m³) which is 0.00068 m³ or 680 cm³ (approx).

Hence, the total surface area of the rectangular prism is 736 in².

A 3D object's surface area is calculated as the total of all of its faces. For instance, if we wanted to figure out how much paint we would need to paint a cube, we would use the cube's surface area.

To calculate the total surface area of the rectangular prism, we need to find the area of each of its six faces and add them together.

The area of the top and bottom faces, which are identical, is:

Length x Breadth = 16 in x 8 in = 128 in².

The area of the front and back faces, which are also identical, is:

Height x Breadth = 10 in x 8 in = 80 in².

The area of the left and right faces, which are also identical, is:

Height x Length = 10 in x 16 in = 160 in².

Therefore, the total surface area of the rectangular prism is:

2(Length x Breadth) + 2(Height x Breadth) + 2(Height x Length)

= 2(16 in x 8 in) + 2(10 in x 8 in) + 2(10 in x 16 in)

= 256 in² + 160 in² + 320 in²
