Answer:

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

[tex]x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}[/tex]

[tex]x=\frac{-1.1+-7.156116265}{0.1}[/tex]

Now make two equations , one with +  and one with -

then we solve for x

[tex]x=\frac{-1.1+7.156116265}{0.1}[/tex]

x=60.56

[tex]x=\frac{-1.1-7.156116265}{0.1}[/tex]

x=-82.56

The solutions for (x) are approximately [tex]\(x_1 \approx 47.5\) and \(x_2 \approx -549.5\).[/tex]

To solve the equation \(0.05x^2 + 1.1x = 250\) using the quadratic formula, follow these steps:

1. Identify the coefficients in the equation: \(a = 0.05\), \(b = 1.1\), and \(c = -250\).

2. Apply the quadratic formula: \[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

3. Substitute the coefficients into the formula and calculate the solutions for \(x\).

The final answer will provide the values of \(x\) obtained from the quadratic formula.

1. Identify the coefficients:

  - \(a = 0.05\)

  - \(b = 1.1\)

  - \(c = -250\)

2. Apply the quadratic formula:

[tex]\[x = \frac{-1.1 \pm \sqrt{(1.1)^2 - 4 \cdot 0.05 \cdot (-250)}}{2 \cdot 0.05}\][/tex]

3. Calculate the solutions for \(x\):

[tex]\[x_1 = \frac{-1.1 + \sqrt{1.21 + 500}}{0.1} \approx 47.5\][/tex]

[tex]\[x_2 = \frac{-1.1 - \sqrt{1.21 + 500}}{0.1} \approx -549.5\][/tex]

Answer: 10

If the line is a perfect fit, then all 10 points are on the same straight line. On the other side of the spectrum, we could have all 10 points not on the line but close enough to it. If the points are too scattered randomly, or they fit a non-linear curve better, then a linear regression line is a bad idea. You can use a correlation coefficient to determine how best the linear fit is.

Answer:

x- intercept = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

to find the x-intercept, that is where the line crosses the x-axis.

let y = 0 in the equation and solve for x, that is

3x - 4 = 0 ( add 4 to both sides )

3x = 4 ( divide both sides by 3 )

x = [tex]\frac{4}{3}[/tex] or ( [tex]\frac{4}{3}[/tex], 0 )

Answer:

x-intercept is 4/3.

Step-by-step explanation:

We have been given the linear equation [tex]y=3x-4[/tex]

For x-intercept, y = 0

Hence, plugging y=0 in the equation and solve for x

[tex]3x-4=0[/tex]

Add 4 to both sides

[tex]3x=4[/tex]

Divide both sides by 3

[tex]x=\frac{4}{3}[/tex]

Hence, x-intercept is 4/3.

The correct statement is: The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic because in an exothermic reaction, heat is released to the surroundings, leading to a decrease in enthalpy.

The correct statement is: The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic. Enthalpy is a measure of the total energy of a thermodynamic system. If the enthalpy decreases during a reaction (negative sign), it implies that heat has been released to the surroundings, which is characteristic of an exothermic reaction. On the other hand, an endothermic reaction absorbs heat from the surroundings, leading to an increase in enthalpy (positive sign).

The correct statement is 'The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic'. When enthalpy of a reaction is negative, it means the energy is being released to surroundings, indicating an exothermic reaction.

The correct statement is 'The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic'. In chemistry, when the enthalpy of a reaction is negative, it indicates that the reaction is exothermic. Exothermic reactions release energy in the form of heat to the surroundings. Thus, if the enthalpy of the reaction is -184.6 kJ, it means the reaction is releasing 184.6 kJ of energy to its surroundings making it an exothermic reaction. In contrast, endothermic reactions absorb heat energy from the surroundings, indicated by a positive enthalpy.

Answer:

As per the statement: Hannah already had 44 photos on her camera when she arrived in Rome.Then she took 24 photos each day for 6 days.

Let x represented day and y represents the number of photo

Total number of 24  photo in x days is, 24x

then; as per the given statement our equation becomes;

y = 24x+44            .....[1]

now, to find the total number of photos took by Hannah for 6 days in Rome;

put x = 6 in [1] we get;

y = 24(6) + 44 = 188

Therefore, the total number of photos on Hannah's Camera is, 188 photos.

To, find the initial value for the linear function y =24x +44.

Initial value or y-intercept, is the output value when the input of a linear function is zero i.e, x = 0.

Substitute x =0 in y =24x +44

y= 24(0) + 44

y = 0 + 44

y = 44

Therefore, the initial value for the equation y =24x+44 is 44 photos.

Answer:its 44 photos!

Answer:

a. Right triangle b. isosceles triangle c. scalene triangle

Answer:

a.  right, scalene

b.  isosceles and acute

c. obtuse and scalene

Step-by-step explanation:

A triangle with a 90 degree angle is a right triangle. Since none of the sides are marked as the same length, we can assume they are not equal, and therefore are scalene ( no sides the same length)

A triangle with 2 angles that are equal is an isosceles triangle.  In this diagram, none of the angles appear to be larger than 90 degrees.  If none of the angles are larger than 90 degrees, than the triangle is acute.

A triangle with with an angle larger than 90 degrees is an obtuse triangle.  Since none of the sides are marked as the same length, we can assume they are not equal, and therefor are scalene ( no sides the same length)

Answer:

-a(a+4)/(16 - a²)

Step-by-step explanation:

            a/(a - 4)                  Multiply by (a + 4)/(a + 4)

= a(a + 4)/[(a – 4)(a + 4)]     Multiply the denominatorator terms

= a(a + 4)/(a² - 16)               Multiply by -1/(-1)

= -a(a+4)/(-a² + 16)              Reorder terms in denominator

= -a(a+4)/(16 - a²)

To estimate the population of the town in 2015, calculate the annual increase from 1950 to 2010 and use it to project the population. The population was found to be approximately 86,000 in 2015.

To determine the population of the town in 2015, we need to calculate the annual rate of population increase between 1950 and 2010 and use it to project the population for 2015. First, we find the total increase over the 60 years from 1950 to 2010:

Total increase = Population in 2010 - Population in 1950
Total increase = 83000 - 47000 = 36000

Then, we find the annual rate of increase by dividing this total increase by the number of years:

Annual Increase = Total increase / Number of years
Annual Increase = 36000 / 60 = 600

Now that we have the annual rate of increase, we can determine the population in 2015:

Population in 2015 = Population in 2010 + (Annual Increase * Number of years since 2010)
Population in 2015 = 83000 + (600 * 5) = 83000 + 3000 = 86000

The population of the town in 2015 is estimated to be 86000 given the constant rate of population increase.

Answer:

The expected value per customer = $6.35.

Step-by-step explanation:

The probability for a $3 commission = 15% = 0.15.

The probability for a $5 commission = 30% = 0.30.

The probability for a $8 commission = 55% = 0.55.

So, the expected value per customer = 3(0.15) + 5(0.30) + 8(0.55)

= 0.45 + 1.50 + 4.40

= 6.35.

Hence, the expected value per customer = $6.35.

Answer:

An equation for the inverse variation y = 2 when x = 5 is:

y=10/x

Step-by-step explanation:

Suppose that y varies inversely with x:

y=k/x

Write an equation for the inverse variation y = 2 when x = 5

Substituting y by 2 and x by 5 in the formula above:

2=k/5

Solving for k: Multiplying both sides of the equation by 5:

5(2)=5(k/5)

10=k

k=10

Then the equation is:

y=k/x

y=10/x

Step-by-step explanation:

the y intercept would be -4 and the slope would be -23, put it in y=mx+b form

Final answer:

The equation of a line with a slope of -23 and a y-intercept of -4 is y = -23x - 4, which corresponds to the option A.

Option A is correct.

Explanation:

The equation of a line is typically written in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. For a line with slope −23 and a y-intercept of −4, we substitute the given values  −23 for m and −4 for b to get the equation y = −23x −4. Therefore, the correct option is A. y=−23x−4.
