Answer:
$39.36
Step-by-step explanation:
Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82
82x0.8= 65.6
Since there is a additional 40% off multiply by 0.4 to get the discount amount
65.6x0.4= 26.24
Subtract the discount from the price
65.6-26.24= 39.36

Answer:
B. The function shown on the graph has a smaller rate of change but a higher starting point
Step-by-step explanation:
Question options obtained from a similar question are;
A. The function shown on the graph has a greater rate of change and a higher starting point
B. The function shown on the graph has a smaller rate of change but a higher starting point
C. The function shown on the graph has a greater rate of change but a lower starting point
The function shown on the graph has a smaller rate of change but a higher starting point
Explanation;
The given function with which the graph is compared is y = 4·x + 2
From the given function, we have;
The rate of change of the function is the coefficient of 'x', therefore, the rate of change of the function = 4
When y = 0, 4·x + 2 = 0,
∴ x = -2/4 = -0.5
The y-intercept is given when x = 0
∴ The y-intercept, y = 4 × 0 + 2 = 2
The starting point of the function, is (0, 2)
From the graph, we have;
The y-intercept = (0, 4)
Therefore, the starting point of the line, the y-intercept, (0, 4), is higher than the starting point of the given function, (0, 2)
The coordinates of two (clear) points on the line in the graph are (0, 4) and (-2, -2)
The rate of change of the line, m = (4 - (-2))/(0 - (-2)) = 3
Therefore, the graph has a lesser rate of change, 3, than the rate of change of the given function, 4
When compared with the given function, 'the function shown on the graph has a smaller rate of change and a higher starting point'.

c. t(60) = 1.76, p> .05, d = .45
d. t(12) = 2.95, p< .05, d = .82
The option that summarizes a t-test that was significant and associated with a large effect size is: d. t(12) = 2.95, p < .05, d = .82
In this option, the t-value is 2.95, indicating a significant result. The p-value is less than .05, indicating that the result is statistically significant at the chosen significance level. Furthermore, the effect size is large, with a Cohen's d value of .82. A large effect size suggests a substantial difference between the groups being compared.
The summary presented in option d is as follows:
t(12) = 2.95, p < .05, d = .82
- t(12) represents the t-value and the degrees of freedom (df) associated with the t-test. In this case, the t-value is 2.95, indicating the magnitude of the difference between the groups being compared. The degrees of freedom is 12, which is determined by the sample size and the design of the study.
- p < .05 indicates the p-value, which is a measure of the probability of obtaining the observed results by chance alone. In this case, the p-value is less than .05, indicating that the difference observed is statistically significant at the .05 significance level.
- d = .82 represents the effect size, specifically Cohen's d. Effect size measures the magnitude of the difference between groups or the strength of the relationship between variables.

The area of a sector fo a circle with radius r. has an arc measure m degrees given by the equation A= m/360pir^2. The area of a sector is 4 square meters and the arc measures 45 degrees. Find the radius of the sector to the nearest meter. Use 3.14 for pi.
The radius of the sector, considering the angle measure and the area of the circle, is given as follows:
3 meters.
How to calculate the area of a circle?The area of a circle of radius r is given by the multiplication of π and the radius squared, as follows:
A = πr²
The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle, on a segment that passes through the center. Hence, the diameter’s length is twice the radius length.
The entire circle has an angle measure of 360º, hence for an angle measure of 45º, the equation is given as follows:
A = 0.125πr²
(as 45/360 = 0.125).
The area is of 4 m², hence the radius is obtained as follows:
4 = 0.125πr²
r = sqrt(4/(0.125π))
r = 3 meters.

Allison is choosing between two rental car companies. Countrywide auto charges $30 plus $0. 21 per mile and smart auto charges $54 plus $0. 18 per mile. Use the system of equations, where y represents total cost and x represents miles, to answer the question. Y
To find the total cost of renting a car from Countrywide Auto or Smart Auto, we need to use the system of equations. The total cost is equal when the number of miles driven is \(800\), and the total cost at this point is $\($198\).
System of equations in which \(y\) represents the total cost and \(x\) represents the number of miles driven. For Countrywide Auto, the equation would be \(y = 0.21x + 30\), and for Smart Auto, it would be \(y = 0.18x + 54.\)
To compare the total cost between the two rental car companies, we need to set the two equations equal to each other and solve for x. This will give us the number of miles at which the total cost of renting from Countrywide Auto is equal to the total cost of renting from Smart Auto. \(0.21x + 30 = 0.18x + 54 0.03x = 24 x = 800\)
Therefore, the total cost of renting from Countrywide Auto is equal to the total cost of renting from Smart Auto when the number of miles driven is \(800\).
To find the total cost at this point, we can substitute \(x = 800\) into either of the equations.
For Countrywide auto,\(y = 0.21(800) + 30 =\) $\(198\), and for Smart auto, \(y = 0.18(800) + 54 =\) $\(198\).
In conclusion, the system of equations \(y = 0.21x + 30\) and \(y = 0.18x + 54\) can be used to compare the total cost of renting a car from Countrywide Auto and Smart Auto. The total cost is equal when the number of miles driven is \(800\), and the total cost at this point is $\(198\).

Answer:
Measure of arc TSU = 201°
Step-by-step explanation:
For the inscribed circle of triangle XYZ, we have;
∠XZY = 21°
Segment TZ and segment UZ are tangent to circle R
Therefore, ∠ZUR = ∠ZTR = 90° (angle formed by a tangent)
Length UR = Length TR = Radius of circle R
∴ ΔZTR ≅ ΔZUR Side Angle Side (SAS) rule of Congruency
∴ ∠RZT ≅ ∠RZU, (Congruent Parts of Congruent Triangles are Congruent, CPCTC)
∠XZY = ∠RZT + ∠RZU (Angle summation)
21° = ∠RZT + ∠RZU = 2×∠RZU (Transitive property)
∠RZU = 21°/2 = 10.5° = ∠RZT
∴ ∠URZ = 180- 90 - 10.5 = 79.5° = ∠TRZ (CPCTC)
arc TU = ∠URT = ∠URZ + ∠TRZ = 79.5 + 79.5 = 159° (angle addition)
∴ Measure of arc TSU = 360° - 159° = 201° (Sum of angles at the center of the circle R)
Measure of arc TSU = 201°.

A new community sports complex is being build in Madison. The perimeter of the rectangular playing field is 466 yards. The length of the field is 7 years less than quadruple the width. What are the dimensions of the playing field?
Answer:
The dimensions of the field is 185 yards by 48 yards
Step-by-step explanation:
Here, we are interested in calculating the dimensions of the field.
Let the width of the field be x yards
From the question, we are made to know that the length of the field is 7 yards less than quadruple ( 4 times) the width
So mathematically, the length of the field will be ;
(4x -7) yards
The perimeter of the field mathematically is:
2(l + b)
Thus;
2(x + 4x- 7) = 466
2(5x -7) = 466
divide both side by 2
5x - 7 = 466/2
5x - 7 = 233
5x = 233 + 7
5x = 240
x = 240/5
x = 48 yards
Length of field is; 4x -7 = 4(48) -7 = 192 - 7 = 185 yards

Suppose that a new employee starts working at $7.08 per hour, and receives a 4% raise each year. After time t, in years, his hourly wage is given by the function P(t)=$7.08(1.04)¹. a) Find the amount of time after which he will be eaming $10.00 per hour. b) Find the doubling time. After what amount of time will the employee be earning $10.00 per hour? ___ years (Round to the nearest tenth of a year.). What is the doubling time? ___ years (Round to the nearest tenth of a year.).
The employee will be earning $10.00 per hour after approximately 3.7 years, and the doubling time, which is the time it takes for the employee's hourly wage to double, is approximately 7.5 years.
The new employee starts with an hourly wage of $7.08 and receives a 4% raise each year. We need to find the amount of time it takes for the employee's hourly wage to reach $10.00. To do this, we can set up the equation $7.08(1.04)^t = $10.00, where t represents the number of years. To solve for t, we divide both sides of the equation by $7.08 and take the logarithm of both sides. This gives us t = log($10.00/$7.08) / log(1.04). Using a calculator, we find that t is approximately 3.7 years. Now let's determine the doubling time, which is the amount of time it takes for the employee's hourly wage to double from its initial value. In this case, we want to find when the hourly wage reaches $14.16 ($7.08 * 2). We can set up the equation $7.08(1.04)^t = $14.16 and solve for t using similar steps as before. Dividing both sides by $7.08 and taking the logarithm gives us t = log($14.16/$7.08) / log(1.04). Using a calculator, we find that t is approximately 7.5 years.
