Answer:

Area of the rectangle = x² - 3x - 10

2019

Step-by-step explanation:

Length of the rectangle = x + 2

Width of the rectangle = x - 5

Area of the rectangle = length × width

= (x + 2) (x - 5)

= x² + 2x - 5x - 10

= x² - 3x - 10

Area of the rectangle = x² - 3x - 10

C = 20t² + 135t + 3050

Where

C = the number of new cars

t = year the number of new cars was purchased

t = 0 corresponds to 1998

Find the when c = 15,000

C = 20t² + 135t + 3050

15,000 = 20t² + 135t + 3050

20t² + 135t + 3050 - 15,000 = 0

20t² + 135t - 11,950 = 0

4t² + 27t - 2390 = 0

Solve using quadratic equation

t = -b ± √b² - 4ac / 2a

= -27 ± √27² - 4(4)(-2390) / 2(4)

= -27 ± √729 -(-38240) / 8

= -27 ± √729 + 38240 / 8

= -27 ± √38969 / 8

= -27/8 + √38969/8 or 27/8 - √38969/8

= -3.375 + 197.41/8 or -3.375 - 197.41/8

= -3.375 + 24.67625 or -3.375 - 24.67625

t = 21.30125 or - 28.05125

t cannot be negative

Therefore,

t = 21.30125

To the nearest whole number

t = 21

Recall,

t = 0 corresponds to 1998

Therefore

1998 + 21 = 2019

c = 15,000 in the year 2019

Step-by-step explanation:

The critical points of the function are (0, 0) and (3/4, -9/4), To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point

To find the critical points of the function f(x, y) = 8x^3 + y^2 + 6xy, we need to find the values of (x, y) where the partial derivatives with respect to x and y are equal to zero.

Taking the partial derivative with respect to x, we have:

∂f/∂x = 24x^2 + 6y = 0.

Taking the partial derivative with respect to y, we have:

∂f/∂y = 2y + 6x = 0.

Solving these two equations simultaneously, we get:

24x^2 + 6y = 0,

2y + 6x = 0.

From the second equation, we can solve for y in terms of x:

Y = -3x.

Substituting this into the first equation:

24x^2 + 6(-3x) = 0,

24x^2 – 18x = 0,

6x(4x – 3) = 0.

Therefore, we have two possibilities for x:

1. x = 0,

2. 4x – 3 = 0, which gives x = ¾.

Substituting these values back into y = -3x, we get the corresponding y-values:

1. x = 0 ⇒ y = 0,

2. x = ¾ ⇒ y = -9/4.

Hence, the critical points of the function are (0, 0) and (3/4, -9/4).

To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point. However, since the original function does not provide any information about the second partial derivatives, further analysis is required to classify the critical points.

m is the amount of miles driven, c is the total cost.

Step-by-step explanation:

Since she has a flat fee of 1275, that's the 1275 in the equation and since we don't know how many miles she drives, that's the m in the equation for miles driven. Since each mile costs 0.20, that's the 0.2 in the equation. And since c is the total cost in dollars, that's the c in the equation.

To arrive at 13.50 for the entity, we can use the following equation: Entity + Arrival = 13.50. Therefore, the answer is 13.50.

To determine how we got 13.50 for the arrival of entity, we need to know the context of the question and the specific calculation that was made. Without this information, it is difficult to accurately answer the question. However, I will provide a general explanation of how to calculate the arrival of an entity.

First, determine the starting point or initial value of the entity. This could be the original cost, initial position, or any other relevant value.

Next, determine the rate of change for the entity. This could be the rate of increase or decrease, the speed of movement, or any other relevant rate.

Finally, use the formula: final value = initial value + (rate of change x time) to calculate the arrival of the entity. In this case, if the initial value was 10 and the rate of change was 0.5 per hour for 7 hours, the final value would be 13.50 (10 + (0.5 x 7)).

1. To make 5 L of a 40% sweet tea concentrate, you need to mix approximately 2.22 L of the 90% sweet tea concentrate with 2.78 L of water.

2. For 400 ml of 790 mM calcium chloride, you would need approximately 34.97 grams of anhydrous calcium chloride.

3. To achieve a final concentration of 20 μM hydrogen peroxide in 10 ml of cells, you would need to add approximately 6.67 μL of a 30 mM stock solution of hydrogen peroxide.

4. To prepare 0.80 liters of culture media, you would need to mix 16 ml of the 50X liquid salt solution with 784 ml of water.

C1V1 = C2V2 where C1 is the initial concentration (90%), V1 is the initial volume (unknown), C2 is the desired concentration (40%), and V2 is the final volume (5 L). Rearranging the equation, we have:

V1 = (C2V2) / C1

Plugging in the values, we get:

V1 = (0.4 * 5 L) / 0.9

V1 ≈ 2.22 L

So, you'll need to mix approximately 2.22 L of the 90% sweet tea concentrate with 2.78 L of water to obtain 5 L of a 40% sweet tea concentrate for your cookout.

To calculate the amount of anhydrous calcium chloride needed for 400 ml of 790 mM calcium chloride, you can use the formula:

mass = molarity × volume × molecular weight

First, convert the molarity from mM to M (mol/L):

790 mM = 0.79 M

Then, calculate the mass using the formula:

mass = 0.79 M × 0.4 L × 110.99 g/mol

mass ≈ 34.97 g

Therefore, you would need approximately 34.97 grams of anhydrous calcium chloride for 400 ml of 790 mM calcium chloride solution.

To determine the amount of a 30 mM stock solution of hydrogen peroxide (H2O2) needed to achieve a final concentration of 20 μM in 10 ml of cells, you can use the formula:

C1V1 = C2V2

Where C1 is the initial concentration (30 mM), V1 is the initial volume (unknown), C2 is the desired concentration (20 μM), and V2 is the final volume (10 ml). Rearranging the equation, we have:

V1 = (C2V2) / C1

Plugging in the values, we get:

V1 = (20 μM × 10 ml) / 30 mM

V1 ≈ 6.67 μL

Therefore, you would need to add approximately 6.67 μL of the 30 mM stock solution of hydrogen peroxide to your 10 ml of cells to achieve a final concentration of 20 μM.

To prepare a stock solution of medium for your culture cells, you'll need to dilute the liquid salt solution and add the required amount of fetal bovine serum (FBS). Since the liquid salt solution is supplied at a 50X concentration and you need a 1X concentration, you'll need to dilute it 50-fold. For a final volume of 0.80 liters, you'll need to mix 0.016 liters (or 16 ml) of the 50X liquid salt solution with 0.784 liters (or 784 ml) of water.

Next, you'll need to calculate the volume of FBS required to achieve a final concentration of 15%. To calculate this, you can use the equation:

V_FBS = (C_FBS × V_total) / C_FBS%

Where V_FBS is the volume of FBS, C_FBS is the desired concentration (15%), V_total is the final volume (0.80 liters), and C_FBS% is the concentration of the supplied FBS (75%). Plugging in the values, we get:

V_FBS = (0.15 × 0.80 liters)

So, there are (n!)^2 ways to arrange n men and n women in a row if they alternate genders.

We need to use the principle of multiplication. We first choose the position of the first person in the row, which can be any of the n men or n women. Without loss of generality, let's say we choose a man. Then, for the next position, we need to choose a woman since we are alternating genders. There are n women to choose from. For the third position, we need to choose another man, and there are n-1 men left to choose from (since we already used one). For the fourth position, we need to choose another woman, and there are n-1 women left to choose from. We continue this pattern until all n men and n women are placed in the row.

Using the principle of multiplication, we can find the total number of ways to arrange the people by multiplying the number of choices at each step. Therefore, the total number of ways to arrange the people in a row if the men and women alternate is:

n * n-1 * n * n-1 * ... * 2 * 1

The system of inequalities that could be used to determine the number of women (w) and men (m) who donated, if no more than $3,130 was donated is:

10w + 15m > 248

w + m < 213

This system of inequalities can be used to model the scenario you've described, where the booth at the circus took donations for the children's hospital, and more than 248 people donated money. The first inequality states that the total number of donations from women (w) multiplied by $10 and the total number of donations from men (m) multiplied by $15 should be greater than 248. The second inequality states that the total number of women (w) and men (m) should be less than 213. The third inequality states that the total amount donated by women (w) multiplied by $10 and total amount donated by men (m) multiplied by $15 should be less than $3,130.

Given data,

Length of Embedded Program = 1

Let the multiply instruction  = 12 cycles

All other instruction  = 4 cycles

Percentage of multiply instructions in embedded program = 15%

Let's calculate the CPI (Cycles Per Instruction) of the old design.

CPI of the old design

\(CPI = (no. of cycles for multiply instruction × % of multiply instruction + no. of cycles for all other instructions × % of all other instructions)/100\)

We know no. of cycles for multiply instruction = 12 cycles

No. of cycles for all other instructions = 4 cycles

\(Percentage of all other instructions = 100% - Percentage of multiply instructions= 100% - 15% = 85%\)

Putting all the values,

\(CPI of the old design= (12 × 15% + 4 × 85%)/100= (1.8 + 3.4)/100= 5.2/100= 0.052\)

CPI of the old design = 0.052

Let's calculate the CPI (Cycles Per Instruction) of the new design.

Cycle time of new design is increased by 20%, it means

the new cycle time will be = 1.2 Old cycle time

New cycle time = 1.2 × Old cycle time

New cycle time / Old cycle time = 1.2

Let's calculate the new cycle time,

Cycle time of new design = 1.2 × 4= 4.8 cycles

The number of cycles for multiply instruction is reduced to 8 cycles

Let's calculate the CPI of the new design.

CPI of the new design

\(CPI = (no. of cycles for multiply instruction × % of multiply instruction + no. of cycles for all other instructions × % of all other instructions)/100\)

We know no. of cycles for multiply instruction = 8 cycles

No. of cycles for all other instructions = 4 cycles

\(Percentage of multiply instructions = 15%Percentage of all other instructions = 100% - Percentage of multiply instructions= 100% - 15% = 85%\)

Putting all the values,

\(CPI of the new design= (8 × 15% + 4 × 85%)/100= (1.2 + 3.4)/100= 4.6/100= 0.046\)
