Answer:

Step-by-step explanation:

Please be sure to include the directions when you post a question.  I will assume you want to graph this inequality 2x - y ≤ 5.  

2x - y = 5 is a linear function whose graph is that of a straight line.  Because of the ≤ sign, the solution set includes all points on this straight line PLUS all  points below it.

x - intercept:  Set y = 0 in 2x - y = 5 and solve the resulting equation for x:

2x - 0 = 5.  Then x = 5/2, and the x-intercept is (5/2, 0).

y-intercept:  Set x = 0 and solve for y:  2(0) - y = 5:  y = -5.  Then the y-intercept is (0, -5).  

Plot both points (5/2, 0) and (0, -5).  Draw a solid line through them.  Shade the area BELOW this line.

Answer:

I know that A is one of the answers.

There are 5 full square and 6 triangles that are half squares.

      5 + (6)(1/2) = 5 + 3 = 8

You could also break this into smaller shapes (like a big triangle on the top and a smaller triangle and rectangle on the bottom and use area formulas to calculate the area.  But counting works well in this example.

Answer: 8

Step-by-step explanation:

First you split up this shape into two different shapes, a triangle and trapezoid

Put a line through the coordinates (-2,2) to  (-1,2); the top is a triangle and the other is a trapezoid

Area of the trapezoid is A = .5x (base1 + base2) x height

base1 of the trapezoid goes from -4 to -1 which is 3

base2 goes from -2 to -1 which is 1

height is 0 to 2 whcich is 2

A = .5 x (3+1) x 2 = 4

Now area of a triangle is A = .5 x base x height

the base goes from -2 to 2 which is 4

the height goes from 2 to 4 which is 2

A = .5 x (4) x (2) = 4

Area of the Trapezoid + Area of the Triangle = Total Area

4 + 4 = 8

1- The combustion of a fuel can be represented as: Fuel + Oxidant (at 298 k)combustion products/ (at very high temperature say Tm). This equation represents the reaction that occurs when a fuel combines with an oxidant, such as oxygen, to produce combustion products. The reaction takes place at a temperature of 298 Kelvin (25 degrees Celsius) and at a very high temperature, denoted as Tm. The combustion products are the substances that are formed as a result of the combustion process.

2- The equilibrium constant at 1727 °C of a reaction can be calculated using the equation: K = exp[(ΔG/RT)], where K is the equilibrium constant, ΔG is the change in Gibbs free energy, R is the gas constant, and T is the temperature in Kelvin. In this case, the equation for calculating ΔG is given as: ΔG = 259,940 + 4.33TlogT - 59.12T cal. By plugging in the temperature of 1727 °C (2000 Kelvin), you can calculate the equilibrium constant K.

3- The normal boiling point of liquid titanium can be calculated using the vapor pressure of liquid titanium at 2227 °C (2500 Kelvin), which is equal to 1.503 mmHg, and the heat of vaporization at the normal boiling point of titanium, which is equal to 104 kcal/mole. By applying the Clausius-Clapeyron equation, ln(P2/P1) = ΔHvap/R(1/T1 - 1/T2), where P1 and P2 are the vapor pressures at temperatures T1 and T2 respectively, ΔHvap is the heat of vaporization, and R is the gas constant, you can calculate the normal boiling point of titanium.

4- The composition of an Al-Mg alloy is given as 91.5 atom % Al in wt% (weight percent). To calculate the composition, you can use the atomic weights of Al and Mg, which are 26.98 and 24.32 respectively. By converting the atomic percent of Al to weight percent, you can determine the composition of the alloy.

5- The partial molar entropy of mixing of magnesium in the Mg-Zn alloy for a reversible cell can be calculated using the equation: ΔS_mix = -RT(δlnX/δX), where ΔS_mix is the partial molar entropy of mixing, R is the gas constant, T is the temperature in Kelvin, δlnX is the change in the natural logarithm of the mole fraction of magnesium, and δX is the change in the mole fraction of magnesium. The temperature coefficient of the cell is given as 0.026 * 10^(-5) V/deg. By plugging in the values and solving the equation, you can calculate the partial molar entropy of mixing.

a. the integral \(I\) becomes \(\[I = a\theta + \sin(\theta) + C\]\) where \(\(C\)\) is the constant of integration. b. the integral \(I\) becomes \(\[I = \frac{1}{2}a\theta^2 + \sin(\theta) + C\]\) where \(\(C\)\) is the constant of integration.

To evaluate the integral \(I = \int (a + \cos(\theta)) \, d\theta\), we can apply the integral rules and properties. Let's consider the two given cases:

(a) If \(a > 1\):

In this case, the integral can be evaluated directly. The integral of \(a\) with respect to \(\theta\) is \(a\theta\), and the integral of \(\cos(\theta)\) is \(\sin(\theta)\). Therefore, the integral \(I\) becomes:

\[I = a\theta + \sin(\theta) + C\]

where \(C\) is the constant of integration.

(b) If \(a = a_0 + i e\), where \(a_0\) and \(e\) are real and positive:

In this case, the integral can also be evaluated using the same rules. The integral of a constant multiplied by a variable is \(\frac{1}{2}a\theta^2\), and the integral of \(\cos(\theta)\) is \(\sin(\theta)\). Therefore, the integral \(I\) becomes:

\[I = \frac{1}{2}a\theta^2 + \sin(\theta) + C\]

where \(C\) is the constant of integration.

It's important to note that the integral is evaluated based on the assumption that \(d\theta\) is the differential of \(\theta\) and not a different variable. Also, \(C\) represents the constant of integration, which can take any value.

The equation 38.28 + 0.42x = C will be used to represent te cost or bill of the rental car driven.

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, we know that:

An initial fee for the rental car: $38.28

Then, charge for every extra mile: $0.42 per mile

The number of miles driven is x.

Step-by-step explanation:

The probability that a randomly selected 6th grade boy weighs less than 116 pounds is about 97.5%.Explanation:Given: Average weight of sixth-grade boys= 100 poundsStandard deviation= 8 poundsWe have to find: Probability that a randomly selected 6th grade boy weighs less than 116 pounds.Z-score is given by the formula:(Value - Mean) / Standard DeviationLet x be the weight of the sixth-grade boy.The z-score will be given as:z = (x - μ) / σwhere μ is the mean weight, σ is the standard deviation.Now we can find the probability using a z-table.The z-table shows the probability that a standard normal distribution will be less than a certain value. Since we can't use the table directly to find the probability less than a particular value, we must convert x into a z-score before using the table.The Z score is calculated as shown below.z = (x - μ) / σ= (116 - 100) / 8= 2.00Using the z-table, we can find that the probability of a z-score less than 2.00 is about 0.975 or 97.5%.Hence, the probability that a randomly selected 6th grade boy weighs less than 116 pounds is about 97.5%.Therefore, option A is correct.

Answer :  D is correct

Given: Sixth grade boys' average weight is 100 pounds with a standard deviation of 8 pounds.

Explanation: The probability that a randomly selected 6th grade boy weighs less than 116 pounds can be calculated as follows:

Step 1: Find the z-scoreTo find the z-score, use the formula: z = (x - μ) / σwhere x = 116, μ = 100, and σ = 8z = (116 - 100) / 8z = 2.0

Step 2: Find the probabilityUsing a z-table or calculator, we can find the probability that a z-score is less than 2.0.

    The probability is approximately 0.9772 or about 97.72%.

Therefore, the probability that a randomly selected 6th grade boy weighs less than 116 pounds is about 97.72%.

Round it to the nearest whole number to get the answer which is about 98%.

Thus, option D is correct.

Answer:

Angle AED: 40
Angle BEC: 105

Explanation:
1) To find Angle AED, you have to do arc BC minus arc AD then divide by 2.
120 - 40 = 80.
80 / 2 = 40

2) To find Angle BEC, you have to do arc BA + CD then divide by 2. But that's only angle CED. You'll have to double the number because BEA is vertical; then minus 360.

62 + 88 = 150
150 / 2 = 75
75 times 2 = 150
360 - 150 = 210
210 / 2 = 105
- You'll divide 210 by 2 because of the vertical angles of AED and BEC.

Selling price = $6.37 .

Selling price = $6.94

Selling price = $346.80

1)

Sales revenue = 6,000

Less:-Variable costs ($1.5 per unit 1,000) = 1,500

Less:- Fixed costs = (1,700)

Operating Income = 2,800

Variable costs and Fixed costs have increased.

Hence, in order to maintain the same Operating Income, the selling price should be higher than the current selling price .

Thus to maintain same operating income the selling price should be $6.37 .

2)

The computation is given below:

Sales price = ( Total sales revenue ÷ packages sold)

Total sales revenue = ( Total Cost + Operating income )

Total Cost = ( Variable Cost + Fixed cost)

Now

Variable cost = 1,000 packages × $1.90 per unit

= $1,900

Fixed cost = $1,700 × 120%

= $2040

Total cost = $1,900 + $2,040

= $3,940

Now  

Total sales revenue is

= $3,940 + $3,000

= $6,940

Now  

Sales price = $6,540 ÷ 1,000 packages

= $6.94
