Answer:

y = (x - 4)² + 2

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (4, 2), thus

y = a(x - 4)² + 2

To find a substitute a point that lies on the curve into the equation

Using the point (2, 6), then

6 = a(2 - 4)² + 2

6 = 4a + 2 ( subtract 2 from both sides )

4 = 4a ( divide both sides by 4 )

a = 1

Hence

y = (x - 4)² + 2 ← equation in vertex form

Answer:

2 hours and 44 mins

Step-by-step explanation:

Final answer:

Mary and her roommate can clean the apartment together in approximately 2.73 hours. This is calculated by adding their individual cleaning rates and then taking the reciprocal of the sum to find the total time.

Explanation:

The question asks how long it would take for Mary and her roommate to clean the apartment if they worked together. Mary can clean the apartment in 6 hours, which means in one hour, she can clean 1/6 of the apartment. Her roommate can clean the apartment in 5 hours, so in one hour, the roommate can clean 1/5 of the apartment. Working together, their combined cleaning rate per hour is 1/6 + 1/5. To find their combined rate, we get a common denominator, which is 30, so their rates become 5/30 and 6/30, respectively. Summing these, we get a combined rate of 11/30 of the apartment cleaned per hour. To find the amount of time it takes for them to clean the entire apartment together, we divide 1 by their combined rate, so 1 / (11/30) = 30/11 hours which is approximately 2.73 hours.

Answer: 45%

Step-by-step explanation: Well in order to get a percent, we need the denominator to be 100 and then the value we get as the numerator is the percentage which we want to calculate.

To get a 100 in the denominator of 9/20, we multiply top and bottom by 5 and we get the equivalent fraction 45/100.

Now the numerator will be our percent which is 45.

So 9/20 is equivalent to 45%.

Answer:

(3,-2)

Step-by-step explanation:

Midpoints bisect a line into two perfectly congruent segments. So, you can find that f was translated down 5=(8-3) and left 1=(5-4). then repeat this step by subtracting x of point e by 1 and the y of point e by 5 to get (3,-2)

Answer:

(3, -2)

Step-by-step explanation:

( x1 + x2 / 2, y1 + y2 / 2 )

x2 = ( x1 + E / 2 ), y2 = ( y1 + E / 2 )

5 + x / 2 = 4, 2(5 + x / 2) = 4(2) = 5 + x = 8, x = 3

8 + y / 2 = 3, 2(8 + y / 2) = 3(2) = 8 + y = 6, y = -2

Answer:

2.61

Step-by-step explanation:

You have to subtract 2.9 to 0.29 because it is a positive number and you have to do the opposite. That will give you -2.61 but you still have to bring down that negative x and to get rid of the negative, you divide both sides by one since there is an understood one beside the x and a number beside another number or variable means multiplication and that will give you, 2.61.

Solving for x in 2.9−x=0.29 is a simple algebraic operation that involves adding x to both sides of the equation to cancel it on the one side and then subtracting 0.29 from both sides to find x = 2.61.

To solve for x in the equation 2.9−x=0.29, you'll need to think about it in terms of moving pieces from one side of the equal sign to the other. Therefore, if we add x to both sides of the equation, it cancels out the variable on the left. So, we have 2.9 = x + 0.29. After that, to isolate x on one side, subtract 0.29 from both sides and we end up with x = 2.9 - 0.29. When we calculate it, we get x = 2.61.

Answer:

x = -1.25

Step-by-step explanation:

2.25x + 5 = 13.5x + 14

subtract five from both sides

2.25x = 13.5x + 9

subtract 13.5x from both sides

-11.25x = 9

swap the negative

11.25x = -9

divide 11.25 from both sides

x = -1.25

Based on the given equation 2.25x+5=13.5x+14; the value of x is 0.8

Like terms refers to terms in an algebraic expression or equation which have the same variable.

2.25x+5=13.5x+14

combine like terms

2.25x - 13.5x = 14 - 5

11.25x = 9

divide both sides by 11.25

x = 9/11.25

x = 0.8

Hence, 0.8 is the value of x in 2.25x+5=13.5x+14

First you would have to write down the number of socks.  That is 6.  That means 6 is the first part of our equation.  Then, we have to multiply this by the $2.  You have to do this because this is how much each pair costs.  Then you would do 2 times 6 equals 12.

Answer:

because a pair of docks is two so multiply by how much pairs she bought

Answer:

160 cups of milk

Step-by-step explanation:

To calculate how many quarts of milk are needed for 80 boxes of pudding mix, you multiply the boxes by the cups per box to find the total cups (240 cups) and then divide by the number of cups in a quart to get 60 quarts.

To determine how much milk will be used to make 80 boxes of pudding mix, we start by calculating the total number of cups of milk needed. Since each box uses 3 cups of milk, the total number of cups for 80 boxes is:

3 cups/box x 80 boxes = 240 cups

Next, we convert cups to quarts. We know that 1 quart equals 4 cups, so we can set up a proportion:

4 cups = 1 quart
240 cups = x quarts

Cross-multiplying to solve for x gives us:

1x = 240/4
x = 60 quarts

Therefore, the cafeteria will use 60 quarts of milk to make 80 boxes of pudding mix.

Answer:

Part a) [tex]f(2)=1.57\ sec[/tex]

It takes 1.57 seconds for an object to fall a distance of 2 feet

Part b) see the explanation

Part c) [tex]2,165.43\ sec[/tex]

Step-by-step explanation:

The complete question is

On the moon, the time, in seconds, it takes for an object to fall a distance, d, in feet, is given by the function f(d) = 1.11√d.

Part a: determine f(2) and explain what it represents.

Part b: The imbrium basin is the largest basin on the moon. A reasonable domain for the height above the lowest point in the basin is given by {d|0 ≤ d ≤ 3805774}. What does this tell you about the basin.

Part c: how long would it take a rock to drop from the rim to the bottom of the basin?

Let

f(d) -----> the time in seconds it takes for an object to fall

d -----> distance in feet

we have

[tex]f(d)=1.11\sqrt{d}[/tex]

Part a): Determine f(2) and explain what it represents

we know that

f(2) represent the time in seconds it takes for an object to fall a distance of 2 feet

For d=2 ft

substitute in the function above and solve for f(2)

[tex]f(2)=1.11\sqrt{2}\\f(2)=1.57\ sec[/tex]

therefore

It takes 1.57 seconds for an object to fall a distance of 2 feet

Part b) The imbrium basin is the largest basin on the moon. A reasonable domain for the height above the lowest point in the basin is given by {d|0 ≤ d ≤ 3805774}

What does this tell you about the basin?

The height of the basin is greater than or equal to 0 ft and less than or equal to 3,805,774 ft  

so

The maximum height of the basin is 3,805,774 ft

Part c) How long would it take a rock to drop from the rim to the bottom of the basin?

we know that

The distance from the rim to the bottom of the basin is equal to the maximum height of the basin

so

[tex]d=3,805,774\ ft[/tex]

substitute the value of d in the function f(d)

[tex]f(d)=1.11\sqrt{3,805,774}\\f(d)=2,165.43\ sec[/tex]

Step-by-step explanation:

To determine the time required to shovel 10 driveways, additional details such as the time for one person to shovel one driveway are needed. The method of snow removal, collaboration efficiency, and driveway conditions are key factors affecting the duration.

To determine how long it will take for you and your friend to shovel 10 driveways, we need more information about the time it takes for one driveway to be shoveled by one person. Since this information is not provided, I cannot give a precise answer. However, I can discuss the factors that will affect the time required to complete the work, including the method of snow removal used, the size and condition of the driveways, the amount of snowfall, and the efficiency of you and your friend while working together.

If using hand shovels, snow blowers, or a pickup truck with a snowplow, the time will vary significantly. With hand shovels, expect it to take the longest time, as this method is labor-intensive. Using a snow blower will reduce the time compared to shoveling by hand. And finally, using a pickup truck with a snowplow will likely be the fastest method, assuming the driveways are accessible and suitable for this equipment.

The efficiency of you and your friend working as a team will also impact the duration. If you work simultaneously on separate driveways, you could potentially cut the time in half, compared to working alone. Therefore, collaboration and the chosen snow removal method will ultimately dictate the total time spent.
