Answer:

The equation of the polynomial in vertex form is \(y +8= (-2)\cdot (x-3)^{2}\), its vertex is \((h,k) = (3, -8)\).

The expression of the axis of symmetry is \(x = 3\).

The y-intercept of the function is -26.

Step-by-step explanation:

The vertex form of the second order polynomial is defined by the following expression:

\(y-k = C\cdot (x-h)^{2}\)  (1)

Where:

\(x\) - Independent variable, dimensionless.

\(y\) - Dependent variable, dimensionless.

\(h,k\) - Coordinates of the vertex, dimensionless.

\(C\) - Vertex constant, dimensionless.

Let \(y = -2\cdot x^{2}+12\cdot x - 26\), then we proceed to present the produre for the determination of the vertex form:

1) \(y = -2\cdot x^{2}+12\cdot x - 26\) Given

2) \(y = (-1)\cdot (2\cdot x^{2})+(-1)\cdot (-12\cdot x) + (-1)\cdot (26)\) \((-a)\cdot (-b) = a\cdot b\)/\((-a)\cdot b = -a\cdot b\)

3) \(y = (-1)\cdot (2\cdot x^{2}-12\cdot x +26)\) Distributive property

4) \(y = [(-1)\cdot (2)]\cdot (x^{2}-6\cdot x +13)\) Associative and distributive properties

5) \(y = (-2)\cdot [(x^{2}-6\cdot x+9)+4]\) \((-a)\cdot b = -a\cdot b\)

6) \(y = (-2) \cdot [(x-3)^{2}+4]\) Perfect square trinomial

7) \(y = (-2)\cdot (x-3)^{2}+4\cdot (-2)\) Distributive property

8) \(y = (-2)\cdot (x-3)^{2}+(-8)\) \((-a)\cdot b = -a\cdot b\)

9) \(y +8= (-2)\cdot (x-3)^{2}\) Compatibility of addition/Existence of the additive inverse/Modulative property/Result.

The equation of the polynomial in vertex form is \(y +8= (-2)\cdot (x-3)^{2}\), its vertex is \((h,k) = (3, -8)\).

The axis of symmetry is a line perpendicular to axis in which the square component of the vertex form is set. The expression of the axis of symmetry is \(x = 3\).

The y-intercept is the value of the polynomial when \(x = 0\), then, the value is:

\(y = -2\cdot (0)^{2}+12\cdot (0) -26\)

\(y = -26\)

The y-intercept of the function is -26.

Raw materials purchases in July - Payment for raw materials purchases in July = Desired ending raw materials inventory for July

X pounds - 0.35 * X pounds = 9,500 pounds

Solving this equation will give us the value of X, which represents the pounds of raw materials that should be purchased in July.

To determine the number of pounds of raw materials that should be purchased in July, we need to calculate the raw materials production needs for August and then consider the inventory policies given in the information provided.

Each unit of finished goods requires 5 pounds of raw materials. The budgeted unit sales for August are 19,000 units. Therefore, the raw materials production needs for August would be 19,000 units multiplied by 5 pounds per unit, which equals 95,000 pounds.

The ending raw materials inventory equals 10% of the following month’s raw materials production needs. Therefore, the desired ending raw materials inventory for July would be 10% of 95,000 pounds, which is 9,500 pounds.

To calculate the raw materials purchases for July, we need to consider the payment terms provided. Thirty-five percent of raw materials purchases are paid for in the month of purchase and 65% in the following month.

Let's assume the raw materials purchases for July are X pounds. Then the payment for 35% of X pounds will be made in July, and the payment for 65% of X pounds will be made in August.

The payment for raw materials purchases in July (35% of X pounds) will be:

0.35 * X pounds

The payment for raw materials purchases in August (65% of X pounds) will be:

0.65 * X pounds

Since the raw materials purchases for July should cover the desired ending raw materials inventory for July (9,500 pounds), we can set up the following equation:

Raw materials purchases in July - Payment for raw materials purchases in July = Desired ending raw materials inventory for July

X pounds - 0.35 * X pounds = 9,500 pounds

Solving this equation will give us the value of X, which represents the pounds of raw materials that should be purchased in July.

Answer:

z = 12

Step-by-step explanation:

Solve for  z  by simplifying both sides of the equation, then isolating the variable.

The number of gallons of water that you drink in a year is 240.9 gallons.

We have to find the number of gallons of water that you drink in a year.

For that, first wee need to find the amount of water that you drink in a day.

Each person will drink water in a day in different amounts.

We can take an average of 2.5 liters that a man drink in a day.

Then

Amount of water drink in a year = 2.5 × 365

                                                      = 912.5 liters

Now we need to find the amount of water in gallons.

Convert liters in gallons.

1 liter = 0.264 gallons

So,

912.5 liters = 912.5 × 0.264 gallons

                  = 240.9 gallons

Hence the amount is 240.9 gallons.

Hope this helps.

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

If A = 136 when \(b_{1}\) = 7 and h = 16, find \(b_{2}\)

We are given the equation that we are working with:

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

We are given certain values that the variables, in this case, are equal to:

A = 136

\(b_{1}\) = 7

h = 16

Substitute the given variables in the given equation for the corresponding numbers:

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)

136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))

We know all the values in the equation except  \(b_{2}\). In order to find  \(b_{2}\) we must isolate it on one side of the equation

136 = 8 (7 + \(b_{2}\))

\(\frac{136}{8}\) = \(\frac{8 (7 + b_{2}) }{8}\)

17 = 7 + \(b_{2}\)

17 - 7 = 7 - 7 + \(b_{2}\)

10 =   \(b_{2}\)

If   \(b_{2}\) is equal to 10 then if we plug it back into the given equation both sides of the equation should equal each other. Remember to use PEMDAS

136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))

136 = \(\frac{1}{2}\) * 16 (7 + 10)

136 = \(\frac{1}{2}\) * 16 (17)

136 = 8 (17)

136 = 136

\(b_{2}\) = 10

If Gavin contributes towards a Pension fund (7,5% of his Basic Salary), then his net salary will be reduced by the amount he contributed towards pension fund i.e. R652.5.

1.1 Name of employee is Gavin Pillay. 1.2 UIF stands for Unemployment Insurance Fund. UIF is a benefit to provide short-term relief to workers who lose their jobs, or can't work due to illness, maternity or adoption leave. 1.3 The UIF paid by Gavin is calculated correctly.

Firstly, we need to calculate Gross Salary of Gavin, which is given as: Basic Salary + Overtime + M = R8700 + R1200 + R3201 = R13101Then, calculate total deductions from gross salary.

Total Deductions = PAYE + UIF = R1200 + 87 = R1287Hence, Gavin's net salary = Gross salary - Total Deductions = R13101 - R1287 = R11814Therefore, UIF paid by Gavin is calculated correctly as R87.1.4 This payslip is for the month of May i.e.

31/05/2023.1.5 Basic salary of Gavin = R8700. Deduct 7.5% of his basic salary to calculate his pension fund contribution. Pension Fund Contribution = 7.5/100 x R8700 = R652.5.1.6

Total deductions of Gavin includes PAYE, UIF and pension fund contribution.

The function f(x) = -2(4)ˣ⁺¹ +140 represents the number of tokens a child has x hours after arriving at an arcade. The practical domain and range of the function are x ≥ 0 and The practical range of the situation is [140, ∞).

The given function is f(x) = -2(4)ˣ⁺¹+ 140, which represents the number of tokens a child has x hours after arriving at an arcade.

To determine the practical domain and range of the function, we need to consider the constraints and limitations of the situation.

For the practical domain, we need to identify the valid values for x, which in this case represents the number of hours the child has been at the arcade. Since time cannot be negative in this context, the practical domain is x ≥ 0, meaning x is a non-negative number or zero.

Therefore, the practical domain of the situation is x ≥ 0.

For the practical range, we need to determine the possible values for the number of tokens the child can have. Looking at the given function, we can see that the term -2(4)ˣ⁺¹represents a decreasing exponential function as x increases. The constant term +140 is added to shift the graph upward.

Since the exponential term decreases as x increases, the function will have a maximum value at x = 0 and approach negative infinity as x approaches infinity. However, due to the presence of the +140 term, the actual range will be shifted upward by 140 units.

Therefore, the practical range of the situation will be all real numbers greater than or equal to 140. In interval notation, we can express it as [140, ∞).

To summarize:

- The practical domain of the situation is x ≥ 0.

- The practical range of the situation is [140, ∞).

Answer:To find the lateral area and surface area of a cone with a diameter of 3.4 centimeters and a slant height of 6.5 centimeters, we first need to find the radius of the cone. The radius is half of the diameter, so it is 1.7 centimeters.

The lateral area of a cone is given by the formula LA = πrs, where r is the radius and s is the slant height. Plugging in the values we have, we get LA = π(1.7)(6.5) = 35.042 square centimeters.

The surface area of a cone is given by the formula SA = πr^2 + πrs, where r is the radius and s is the slant height. Plugging in the values we have, we get SA = π(1.7)^2 + π(1.7)(6.5) = 47.097 square centimeters.

Therefore, the lateral area of the cone is approximately 35.042 square centimeters and the surface area of the cone is approximately 47.097 square centimeters.
