Its speed of Rachel would be 30 meters per second.

Given that,

Stunt driver Rachel is trying to get out of a building that is going to blow up.

Here, the equation is,

\(d = - 38t + 220\)

Where, variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.

Now, Velocity is the rate at which a distance changes over time.

\(d = - 38t + 220\)

\(\dfrac{d(d)}{dt} = - 38\)

Hence, Speed is the magnitude of velocity.

\(|- 38| = 38\)

Answer: D

Explanation:

Use the vertex formula, -b/2a. Because the quadratic formula is ax^2+bx+c, -b would be 5 in this case and a would be 2 in this case. Plug the numbers in and you get 5/4. The AOS or vertex would be 5/4 or 1.25. Because the a-value is a positive in this equation, the parabola would have a minimum.  

Answer

(x + 2)² + 6 = 0

Explanation

We are asked to express the quadratic equation in its completed square form.

The way to do this is to add and subtract the square of the half of the coefficient of x from the left hand side.

Coefficient of x = 4

Half of the coefficient of x = (4/2) = 2

Square of the half of the coefficient of x = 2² = 4

x² + 4x + 10 = 0

x² + 4x + 4 - 4 + 10 = 0

x² + 4x + 4 + 6 = 0

x² + 2x + 2x + 4 + 6 = 0

x(x + 2) + 2 (x + 2) + 6 = 0

(x + 2) (x + 2) + 6 = 0

(x + 2)² + 6 = 0

Answer:

x = -8

Step-by-step explanation:

3(x+1)+11=-2(x+13)

3x+3+11=-2x-26

3x+14=-2x-26

5x=-40

x=-8

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

3(x + 1) + 11 = -2(x + 13)

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

3(-8 + 1) + 11 = -2(-8 + 13)

3(-7) + 11 = -2(5)

-21 + 11 = -10

Given statement solution is :- When the weight of apples is increased by a factor of 4, the total cost also increases by a factor of 4. The correct answer is 4, not 8.

To determine the factor by which the total cost increases when the weight of apples is increased by a factor of 4, let's examine the relationship between the weight and total cost in the given ratio table.

Weight (lb) | Total cost (S)

1 | 2

4 | 8

6 | 12

10 | 20

To find the factor by which the total cost increases, we need to compare the change in total cost to the change in weight. Let's consider the first and last entries in the table:

Initial weight: 1 lb

Initial total cost: 2 S

Final weight (increased by a factor of 4): 4 * 1 lb = 4 lb

Final total cost: 8 S

The change in weight is from 1 lb to 4 lb, which is a factor of 4. The change in total cost is from 2 S to 8 S, which is also a factor of 4.

Therefore, when the weight of apples is increased by a factor of 4, the total cost also increases by a factor of 4. The correct answer is 4, not 8.

Answer:

Density = mass / volume

We are given the mass of the liquid, which is 53.64 grams. We also know that the volume of the liquid is 18.0 milliliters.

However, we need to take into account the temperature of the liquid to determine its density at 15°C. The density of liquids typically changes with temperature.

Assuming that we know the density of the liquid at some other temperature, we can use the following formula to adjust the density to 15°C:

Adjusted Density = Measured Density / [1 - (T2 - T1) * Coefficient]

where:

Measured Density is the density of the liquid at some known temperature

T1 is the known temperature in Celsius

T2 is the desired temperature in Celsius (in this case, 15°C)

Coefficient is the coefficient of thermal expansion for the liquid

The coefficient of thermal expansion varies depending on the specific liquid. For water, which has a coefficient of thermal expansion of 0.00021 per degree Celsius, the adjusted density formula becomes:

Adjusted Density = Measured Density / [1 - (T2 - T1) * 0.00021]

Assuming that the liquid in question has a coefficient of thermal expansion similar to that of water, we can use this formula to adjust the density to 15°C.

Density = mass / volume = 53.64 g / 18.0 mL = 2.98 g/mL

Using the adjusted density formula:

Adjusted Density = 2.98 / [1 - (15 - 20) * 0.00021] = 2.98 / [1 - (-0.00105)] = 2.982 g/mL

Therefore, the density of the liquid at 15°C is approximately 2.982 g/mL.

The calculation \((9.04-8.23+21.954+81.0) \times 3.1416\) would have 4 significant figures.



To determine the number of significant figures in a calculation, we follow the rules for significant figures:

1. Addition and subtraction: The result should have the same number of decimal places as the measurement with the fewest decimal places.
2. Multiplication and division: The result should have the same number of significant figures as the measurement with the fewest significant figures.

Let's break down the calculation step by step:
\(9.04-8.23+21.954+81.0\) yields \(104.764\).

Now, multiplying this result by \(3.1416\) gives \(329.5719744\).

The measurement with the fewest significant figures in the calculation is \(3.1416\), which has 5 significant figures.

According to the rule for multiplication and division, the result should have the same number of significant figures as the measurement with the fewest significant figures. Hence, the result, \(329.5719744\), will be rounded to 4 significant figures.

Therefore, the calculation \((9.04-8.23+21.954+81.0) \times 3.1416\) would have 4 significant figures.

Option 1: An open rectangular box is to be made by cutting four equal squares from each corner of a 12 cm by 12 cm piece of metal and then folding up the sides.

Let's denote the side length of each square cut from the corners as x. After cutting the squares and folding up the sides, the resulting open rectangular box will have dimensions of (12-2x) cm by (12-2x) cm by x cm. The volume of the box can be calculated as V(x) = x(12-2x)(12-2x).

To find the domain of the function V(x), we need to consider the restrictions on x. Since we are cutting squares from the corners, the side length of each square cannot exceed half of the original length, i.e., x ≤ 6 cm. Therefore, the domain of V(x) is [0, 6].

To find the range of V(x), we need to determine the maximum value of V(x) within the given domain. We can find this by evaluating the function at the critical points, which are the endpoints of the domain and any points where the derivative of V(x) is equal to zero.

At x = 0, we have V(0) = 0(12)(12) = 0.

At x = 6, we have V(6) = 6(12-12)(12-12) = 0.

The maximum value of V(x) within the domain [0, 6] occurs at the endpoints, and the value is 0. Therefore, the range of V(x) is [0, 0].

In conclusion, the domain of the volume function V(x) is [0, 6], the range is [0, 0], and the maximum volume achievable for the open rectangular box is 0 cm³.

Multiply the fraction 1/4 by 2/2, 3/3, 4/4, 5/5, etc. until you get x/20. Then you have 20 girls. x is the number of boys.
