Cost of chicken wings at Buffalo Bills = 8 wings for $7

Cost of 1 wing at Buffalo Bills = [tex]\frac{7}{8} =0.875[/tex]

Cost of chicken wings at Buffalo Mild Wings = 12 wings for $10

Cost of 1 wing at Buffalo Mild Wings = [tex]\frac{10}{12}= 0.833[/tex]

Cost of chicken wings at Wingers = 20 wings at $17

Cost of 1 wing at Wingers = [tex]\frac{17}{20}= 0.850[/tex]

Hence, comparing all the three costs per wing, we can see that Buffalo Mild Wings is serving chicken wings at lowest price of $0.833 per wing.

Answer:

It is B

Step-by-step explanation:

a) The given function is

[tex]f(x)=\frac{x^2-4}{x^4+x^3-4x^2-4}[/tex]

The domain refers to all values of x for which the function is defined.

The function is defined for

[tex]x^4+x^3-4x^2-4\ne0[/tex]

This implies that;

[tex]x\ne -2.69,x\ne 1.83[/tex]

b) The vertical asymptotes are x-values that makes the function undefined.

To find the vertical asymptote, equate the denominator to zero and solve for x.

[tex]x^4+x^3-4x^2-4=0[/tex]

This implies that;

[tex]x= -2.69,x=1.83[/tex]

c) The roots are the x-intercepts of the graph.

To find the roots, we equate the function to zero and solve for x.

[tex]\frac{x^2-4}{x^4+x^3-4x^2-4}=0[/tex]

[tex]\Rightarrow x^2-4=0[/tex]

[tex]x^2=4[/tex]

[tex]x=\pm \sqrt{4}[/tex]

[tex]x=\pm2[/tex]

The roots are [tex]x=-2,x=2[/tex]

d) The y-intercept is where the graph touches the y-axis.

To find the y-inter, we substitute;

[tex]x=0[/tex] into the function

[tex]f(0)=\frac{0^2-4}{0^4+0^3-4(0)^2-4}[/tex]

[tex]f(0)=\frac{-4}{-4}=1[/tex]

e) to find the horizontal asypmtote, we take limit to infinity

[tex]lim_{x\to \infty}\frac{x^2-4}{x^4+x^3-4x^2-4}=0[/tex]

The horizontal asymtote is [tex]y=0[/tex]

f) The greatest common divisor of both the numerator and the denominator is 1.

There is no common factor of the numerator and the denominator which is  at least a linear factor.

Therefore the function has no holes.

g) The given function is a proper rational function.

There is no oblique asymptote.

PARALLEL slopes always have the same slope no matter what because they are parallel

Answer:

A = 204  

Step-by-step explanation:

The formula for the area of a parallelogram is

A = bh

Data:

   P = 60

   h = AX =12

MX = 5

Calculation:

MA² = MX² + h² = 5² + 12² = 25 + 144 = 169

MA  = √169 = 13

P = 2MA + 2MH =  2MA + 2(MX + HX) = 26 + 2(5 + HX) = 60

 26 + 10 + 2HX = 60

         36 + 2HX = 60

                 2HX = 24

                   HX = 12

b = MH = MX + HX  = 5 + 12 = 17

A = bh =17 × 12 = 204

The area of the parallelogram is 204.

Final answer:

The maximum height of the twig is approximately 0.570 meters. The twig will hit the ground approximately 0.683 seconds after being flicked up.

Explanation:

To find the maximum height of the twig, we can use the kinematic equation for vertical motion. The equation is given by:

h = v0y2 / (2g)

Where:

h is the maximum height

v0y is the initial vertical velocity

g is the acceleration due to gravity (approximately 9.8 m/s2)

Plugging in the values, we have:

h = (11 ft/s)2 / (2 * 9.8 m/s2)

Converting the initial velocity from feet per second to meters per second:

11 ft/s * 0.3048 m/ft = 3.35 m/s

Substituting the values into the equation:

h = (3.35) / (2 * 9.8)

Simplifying the equation:

h = 0.570 m

Therefore, the maximum height of the twig is approximately 0.570 meters.

To find when the twig will hit the ground, we can use the equation for time in vertical motion:

t = 2 * v0y / g

Plugging in the values, we have:

t = 2 * 3.35 m/s / 9.8 m/s2

Simplifying the equation:

t = 0.683 s

Therefore, the twig will hit the ground approximately 0.683 seconds after being flicked up.

Answer is B

Step-by-step explanation:

To find the workers' compensation insurance premium, multiply the payroll for September ($179,805) by the base rate converted to decimal (0.1124), resulting in a premium of $20,210.08 (Option A).

The question involves calculating the premium for workers' compensation insurance based on the total payroll for the month of September. To determine the monthly premium, we need to apply the base rate to the total payroll amount. The base rate is given as $11.24 per $100 in wages paid. We can calculate the premium with the following steps:

Convert the base rate to a decimal by dividing by 100. This will give us 0.1124.

Multiply the total payroll amount ($179,805) by the decimal base rate (0.1124) to get the premium amount.

Let's perform the calculation:

$179,805 * 0.1124 = $20,210.08

Therefore, the correct option is:

A) $20,210.08

Answer:

y = -3.3 then  -7.1

y = -7.1 then  -10.9

y = -2.6 then -6.4

y = 1 then -2.8

y = 4.2 then 0.4

Step-by-step explanation:

(-3.8)+0+y can be simplified to -3.8 + y. Evaluate each value for y by substituting it into the expression and solving.

y = -3.3 then -3.8 + -3.3 = -7.1

y = -7.1 then -3.8 + -7.1 = -10.9

y = -2.6 then -3.8 + -2.6 = -6.4

y = 1 then -3.8 + 1 = -2.8

y = 4.2 then -3.8 + 4.2 = 0.4

To evaluate the expression (-3.8) + 0 + y, substitute the given value of y and perform addition.

To evaluate the expression (-3.8) + 0 + y, you simply substitute the given value of y into the expression and perform the addition. Let's evaluate the expression for each given value of y:

Answer:

x = 13

Step-by-step explanation:

The area of a rectangle is found by A = l*w. Since the length here is x and the width is 2x - 8, substitute these values and A = 234 to solve for x.

[tex]A = l*w\\234 = x(2x-8)\\234 = 2x^2 - 8x[/tex]

To solve for x, move 234 to the other side by subtraction. Then remove the common factor between all three terms of 2. Factor and solve.

[tex]2x^2 - 8x  - 234 = 0 \\2(x^2 - 4x - 117) = 0\\2(x - 13)(x+9) = 0\\[/tex]

Set each factor equal to 0 and solve.

x - 13 = 0 so x = 13

x + 9 = 0 so x = -9

Since x is a side length and length/distance cannot be negative, then x = 13 is the length of the rectangle.

Answer:

D) 4/5

Step-by-step explanation:

He drew and replaced cards 10 times.

8 out of the 10 times, he drew a red card.

8/10 = 4/5

Answer: D) 4/5

You are correct.

Final answer:

The experimental probability of drawing a red card, based on the information given, is 4/5, since Marco drew 8 red cards out of 10 total draws.

Explanation:

The student is asking for the experimental probability of drawing a red card based on Marco's actual draws from a standard deck of 52 cards. Experimental probability is calculated by dividing the number of times the event of interest (drawing a red card) occurred by the total number of trials. In this case, Marco drew a red card 8 times out of 10 total draws.

Therefore, the experimental probability is:

Experimental Probability = Number of red cards drawn / Total number of draws = 8/10

When simplified, 8/10 equals 4/5. Therefore, the correct answer is:

Experimental Probability of Drawing a Red Card = 4/5

Step-by-step explanation:

We have a sample mean of 35, a sample standard deviation of 8, and a sample size of 36.  

You need to see that the probability of the number of items you can deliver in a day is between 32.6 and 34.6.

The answer is 0.3462, so there's about a 34.62% chance that you will deliver an average of 32.6 to 34.6 packages per day.

The probability a random sample of 36 days would have a mean between 32.6 and 34.6 is 0.3462

Mean is actually the average of all the observations.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean

A z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

According to the problem,

Here we need to find  P(32.6 < x < 34.6)

[tex]z_{32.6}[/tex] = [tex]\frac{32.6-35}{\frac{8}{\sqrt{36} } }[/tex] = - 1.80

[tex]z_{34.6} = \frac{34.6-35}{\frac{8}{\sqrt{36} } }[/tex] = -0.30

∴ P(32.6 < x < 34.6) = P ( -1.80 < z < -0.30)

= P(z< -0.30) - P(z < -1.80)

= 0.3821 - 0.0359 = 0.3462

∴  The required probability is 0.3462

ANSWER

a. 2 real roots, 2 imaginary roots

EXPLANATION

The given equation is

[tex] {x}^{4} - 64 = 0[/tex]

We rewrite as difference of two squares,

[tex]( {x}^{2} )^{2} - {8}^{2} = 0[/tex]

We factor using difference of two squares to get;

[tex]( {x}^{2} - 8)( {x}^{2} + 8) = 0[/tex]

We now use the zero product property to get:

[tex]{x}^{2} = 8 \: or \: {x}^{2} = - 8[/tex]

Take the square root of both sides to get;

[tex]{x} = \pm \sqrt{8} \: or \: {x}^{2} = \pm \sqrt{ - 8} [/tex]

[tex]{x} = \pm 2\sqrt{2} \: or \: {x} = \pm 2\sqrt{ 2} i[/tex]

[tex]{x} = - 2\sqrt{2} \: or \: {x} = 2\sqrt{ 2}[/tex]

are two real roots.

[tex]{x} = - 2\sqrt{2}i \: or \: {x} = 2\sqrt{ 2} i[/tex]

are two imaginary roots.

The correct answer is A.

The correct answer is a. 2 real roots, 2 imaginary roots.

To determine the number and type of roots for the equation [tex]\(x^4 - 64 = 0\)[/tex]

1. Start with the equation:

[tex]\[ x^4 - 64 = 0 \][/tex]

2. Rewrite the equation as a difference of squares:

[tex]\[ x^4 - 64 = (x^2)^2 - 8^2 = (x^2 - 8)(x^2 + 8) = 0 \][/tex]

3. Set each factor equal to zero:

[tex]\[ x^2 - 8 = 0 \]\[ x^2 + 8 = 0 \][/tex]

4. Solve each equation separately:

For [tex]\(x^2 - 8 = 0\)[/tex]:

[tex]\[ x^2 = 8 \]\[ x = \pm \sqrt{8} = \pm 2\sqrt{2} \][/tex]

These are two real roots.
