Answer:

[tex](x-2)^2=-12(y+1)[/tex]

Step-by-step explanation:

From observation of the given diagram, we can see that the graphed conic section is a vertical parabola that opens downwards, with a vertex at (2, -1) and a focus at (2, -4).

The equation of a vertical parabola in standard form is:

[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Standard form of a vertical parabola}\\\\$(x-h)^2=4p(y-k)$\\\\where:\\ \phantom{ww}$\bullet$ $p\neq 0$\\ \phantom{ww}$\bullet$ Vertex: \;$(h,k)$\\ \phantom{ww}$\bullet$ Focus:\; $(h,k + p)$\\\end{minipage}}[/tex]

Given the vertex is (2, -1):

Given the formula for the focus is (h, k+p), then:

[tex]\begin{aligned}(h, k+p)&=(2, -4)\\(2,-1+p)&=(2,-4)\\\\\implies -1+p&=-4\\p&=-4+1\\p&=-3\end{aligned}[/tex]

To write the equation of the graphed conic section, substitute the found values of h, k and p into the standard formula:

[tex](x-2)^2=4(-3)(y-(-1))[/tex]

[tex](x-2)^2=-12(y+1)[/tex]

Therefore, the equation of the graphed conic section is:

[tex]\boxed{(x-2)^2=-12(y+1)}[/tex]

Note that based on the volume  calculations,  the manager's statement is NOT correct. The given area of 2m × 2m is insufficient to store all 80 crates.

To verify if the manager's statement is correct, we need to derive the volume of each crate and the total volume required to store all 80 crates.

Volume = Length × Width × Height

Recall that

Length (L) = 690 mm

Width (W) = 445 mm

Height (H) = 180 mm

Thus, the Volume of one crate is

Volume = 690 mm × 445 mm × 180 mm

Converting mm to meters we have,

Volume = (690 / 1000)  × (445 / 1000)  × (180 / 1000)

= 0.690  × 0.445 × 0.180

= 0.055269 m³

Next , we calculate the total volume required for 80 crates as

Total Volume = Volume of one crate × Number of crates

= 0.055269 m³ × 80

= 4.42152 m³

Recall that the manager stated that all 80 crates can be packed in a 2m × 2m area in the store room.

Since area of store room is

Area = 2 m × 2 m

Area = 4 m²

Comparing the total volume required (4.380208 m³) with the available area (4 m²), we see that the volume exceeds the area. Tus, the manager's statement is incorrect.

A lead atom is 200 times heavier than a hydrogen atom.

To determine how many times heavier a lead atom is compared to a hydrogen atom, we can calculate the ratio of their masses.

Mass of hydrogen = 1.7 × 10⁻²⁴ grams

Mass of lead atom = 3.4 × 10⁻²² grams

To find the ratio of their masses, we divide the mass of the lead atom by the mass of the hydrogen atom:

Ratio = 3.4 × 10⁻²² /  1.7 × 10⁻²⁴

= (3.4 / 1.7)× 10⁻²² / 10⁻²⁴

Answer:

Measure of angle HEK is: 85°.

Step-by-step explanation:

Given that point E is the center of the protractor, we have:

angle HEJ = 55° (EH points to 55 degrees)

angle JEK = 30° (EK points to 30 degrees)

Since angle HEJ and angle JEK meets at a point E, then we can find angle HEK by summing up the two angles:

angle HEK = angle HEJ + angle JEK

angle HEK = 55° + 30°

angle HEK = 85°

All the values of a 12-sided die will be represented by two 6-sided die. The probability of rolling a 7 on the 12-sided die is 1/12 and rolling a sum of 7 on the two 6-sided dice will be 1/6.

The 12-sided die which is dodecahedral consists of numbers up to 12. The 6-sided die consists of numbers up to 6. The suggestion of using two 6-sided dice instead of a 12-sided die will make a difference in the probabilities of a specific outcome.

Although, using a pair of 6-sided dice and adding their scores will represent all the values or outcomes you can get in a 12-sided die but still there will be a difference in the probabilities.

If we find the probability of rolling 7 on the 12-sided die, then it will be 1/12.

But, in the case of two 6-sided dice, we will obtain the sum of 7 in 6 outcomes which are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). The total number of outcomes, in this case, is 36.

The ratio of black to red cards in the deck is now 26:25.

On the second draw, there will be only 51 cards to choose from, rather than 52 because you have already taken out a card. Therefore, you only have a 25/51 chance of drawing a red card compared to the 26/52 or 1/2 chance on the first draw.

Part A:  At her current rate, the distance Amy can ride her bike within 12 minutes is A. 1.6 miles.

Part B: Sebastian can ride his bike for  C: 7.5 miles in 1 hour.

Part C: The time it will take for one to wait is B: Amy will have to wait 1.5 minutes for Sebastian.

Part A:

To find the distance Amy can ride her bike in 12 minutes, we set up a proportion based on her current rate.

Amy's rate: 4 miles / 30 minutes = x miles / 12 minutes

Cross-multiplying:

30x = 4 * 12

30x = 48

Dividing both sides by 30:

x = 48 / 30

x ≈ 1.6

So, Amy can ride her bike at 1.6 miles in 12 minutes.

Part B:

To find the distance Sebastian can ride his bike in 1 hour, convert the time to minutes first.

1 hour = 60 minutes

Sebastian's rate: 3 miles / 24 minutes = x miles / 60 minutes

Cross-multiplying:

24x = 3 * 60

24x = 180

Dividing both sides by 24:

x = 180 / 24

x ≈ 7.5

Therefore, Sebastian can ride his bike at 7.5 miles in 1 hour.

Part C:

Amy's home to  Park = 3 miles,

Park to Sebastian's home = 3 miles.

Amy's rate = 4 miles in 30 minutes, equivalent to 1 mile in 7.5 minutes.

Sebastian's rate = 3 miles in 24 minutes, equivalent to 1 mile in 8 minutes.

Then, we estimate the time it takes for each to cover a distance of 3 miles.

Amy:

Time = Distance / Rate = 3 miles / (2/15 miles/minute)

= 3 * (15/2) minutes

= 22.5 minutes

Sebastian:

Time = Distance / Rate = 3 miles / (1/8 miles/minute)

= 3 * 8 minutes

= 24 minutes

Since Amy= 22.5 mins and Sebastian takes 24 mins,

24 - 22.5 = 1.5

Hence, Amy will have to wait 1.5 minutes for Sebastian.

The mean monthly income is $3300, the median monthly income is $3000, there is no mode, and the range of the monthly income is $3000.

To find the mean, median, mode, and range of the monthly incomes, we'll perform the following calculations:

Mean:

The mean is calculated by summing all the values and dividing by the total number of values.

Mean = (2000 + 2500 + 3000 + 4000 + 5000) / 5

Mean = 16500 / 5

Mean = 3300

The mean monthly income is $3300.

Median:

The median is the middle value when the data is arranged in ascending order. In this case, since we have an odd number of values, the median is the middle value.

Arranging the incomes in ascending order: $2000, $2500, $3000, $4000, $5000

The median monthly income is $3000.

Mode:

The mode is the value(s) that appear most frequently in the data. In this case, there is no value that appears more than once, so there is no mode.

The data has no mode.

Range:

The range is calculated by subtracting the minimum value from the maximum value.

Range = Maximum Value - Minimum Value

Range = $5000 - $2000

Range = $3000

The range of the monthly income is $3000.
