A bus traveled on a level road for 6 hours at an average speed 20 miles per hour faster than it traveled on a winding road The time spent on the winding road was 3 hours Find the average speed on the level road the entire trip was 534 miles
The bus’s speed was on the level road was ( ) mph?
The bus’s speed on the level road was 72 mph if the bus traveled on a level road for 6 hours at an average speed of 20 miles per hour.
The given data is as follows:
The bus traveled on road time = 6 hours
Average speed = 20 miles/hour
Time spent on the winding road = 3 hours
Entire trip distance = 534 miles
The equation will be written as:
(x+20) * (6) + (x)(2) = 534
Now, "x" is the average speed on the winding road.
solving for x value,
6x + 120 + 2x = 534
8x = 534 -120
x = 414/8
x = 52
Now, we calculated the average speed for the winding road.
The average speed for the level road is calculated as:
u1 + v1 = 52 + 20 = 72
Therefore we can conclude that the bus’s speed on the level road was 72 mph.

member to check for extraneous solutions. ( 4 points ). (1)/(x+2)+(3)/(x+7)=(5)/(x^(2)+9x+14)
The extraneous solutions of the equation (1)/(x+2)+(3)/(x+7)=(5)/(x²+9x+14) are x = 0, x = -7, and x = -14
To solve this equation, we must first simplify each side of the equation and then use the rule of equality. We can do this by finding the least common denominator (LCD) of the equation. In this case, the LCD is (x+2)(x+7)(x²+9x+14).
To simplify each side, we must multiply each term by the LCD divided by its original denominator. This leaves us with:
(x+2)(x+7)(x^2+9x+14) / (x+2) + (x+2)(x+7)(x²+9x+14) / (x+7) = (x+2)(x+7)(x²+9x+14) / (x²+9x+14)
We can now apply the rule of equality to solve the equation:
x³+11x²+37x+98 = 0
To find the solution of the equation, we must now factor the left side of the equation. We can do this by first factoring out a common factor of x, which gives us:
x(x²+11x+98) = 0
We can now factor the remaining trinomial, which gives us:
x(x+7)(x+14) = 0
Therefore, the extraneous solutions of the equation are: x = 0, x = -7, and x = -14

Both circles have the same center. The circumference of the inner circle is 125.6 inches. What is the area of the shaded region?
Use 3.14 for pi. Write your answer as a whole number or decimal rounded to the nearest hundredth.
Using the circumference formula of the circle, we know that the area of the shaded region is 2,375 in.
The circumference of a circle is the distance encircling its edge.
The diameter of a circle is the distance measured through its center.
The radius of a circle is the distance from the center to any point on the edge.
The circumference of a circle or ellipse in geometry is its perimeter.
That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.
The curve length around any closed figure is more often referred to as the perimeter.
So, the circumference of the inner circle is 125.6 inches.
Then, the radius would be:
C = 2πr
125.6 = 2πr
125.6 = 6.28r
r = 125.6/6.28
r = 20 in
r for the outer circle: r will be 20 + 14 = 34 in
Area of the inner circle:
A = πr²
A = π20²
A = 1256.63706
A = 1257 in
Area of the outer circle:
A = πr²
A = π34²
A = 3631.68111
A = 3632 in
Area of the shaded region:
3632 in - 1257 in = 2,375 in
Therefore, using the circumference formula of the circle, we know that the area of the shaded region is 2,375 in.

The first step in the industrial recovery of zinc from zinc sulfide ore is roasting. That is the conversion of ZnS to ZnO by heating: 2ZnS (s)- 30₂(g) → 2ZnO(s) - 250, (g) AH=-879 kJ/mol Calculate the heat (in kJ) associated with roasting 6.00 grams of zinc sulfide. Round your answer to 3 significant digits.
The heat associated with roasting 6.00 g of zinc sulfide is 27.1 kJ.
How to solve thisThe molar mass of ZnS is 97.45 g/mol, which means that 6.00 g of ZnS is equal to:
6.00 g ZnS × (1 mol ZnS/97.45 g ZnS) = 0.0616 mol ZnS
According to the balanced equation, the roasting of 2 mol of ZnS releases 879 kJ of heat:
2 ZnS (s) + 3 O₂ (g) → 2 ZnO (s) + 2 SO₂ (g) ΔH = -879 kJ/mol
Therefore, the roasting of 0.0616 mol of ZnS releases:
(879 kJ/mol) × (0.0616 mol ZnS / 2 mol ZnS) = 27.1 kJ
Therefore, the heat associated with roasting 6.00 g of zinc sulfide is 27.1 kJ. Rounded to three significant digits, the answer is 27.1 kJ.

(c) Let A be a matrix of size n × n. If for two vectors y and z of R^n we have Ay = Az, then we always have y = z.
(d) If A is a matrix of size n × n such that A^3 = I(n) then A is invertible.
(e) For any two matrices A and B of size n×n such that AB = 0, then A = 0 or
B = 0.
(a) True
(b) True
(c) False
(d) True
(e) False
(a) True. For any n × n invertible matrix A, the equation Ax = 0 admits only the trivial solution. This is because if A is invertible, then there exists an inverse matrix A^-1 such that A^-1A = I, where I is the identity matrix. Therefore, if Ax = 0, then A^-1Ax = A^-10, or x = 0. This means that the only solution to the equation is the trivial solution x = 0.
(b) True. For any two matrices A and B of size n × n, (AB)^T = (B^T) (A^T). This is a property of matrix multiplication and transposition, and can be easily verified by performing the operations on the matrices.
(c) False. Let A be a matrix of size n × n. If for two vectors y and z of R^n we have Ay = Az, it does not necessarily mean that y = z. It is possible for two different vectors to produce the same result when multiplied by the same matrix. For example, consider the matrix A = [[1, 0], [0, 1]] and the vectors y = [1, 0] and z = [0, 1]. Both Ay and Az will result in the same vector [1, 1], but y and z are clearly not equal.
(d) True. If A is a matrix of size n × n such that A^3 = I(n), then A is invertible. This is because A^3 = I(n) implies that A^2 = A^-1, meaning that the inverse of A exists and A is invertible.
(e) False. For any two matrices A and B of size n×n such that AB = 0, it is not necessarily true that A = 0 or B = 0. It is possible for two non-zero matrices to multiply to produce the zero matrix. For example, consider the matrices A = [[1, -1], [1, -1]] and B = [[1, 1], [1, 1]]. Both A and B are non-zero matrices, but AB = 0.

Which function represents a horizontal dilation of the function y = log x ? Select all that apply.
The functions that represent a horizontal dilation of the function y = log x are A and C.
What is horizontal dilation?
Horizontal dilation, also known as horizontal stretching or compression, is a transformation of a function that changes the shape of its graph by scaling the independent variable (x-axis).
When a function is horizontally dilated, it is stretched or compressed horizontally without changing its vertical position. If the function is stretched horizontally, it becomes flatter and wider, while if it is compressed horizontally, it becomes steeper and narrower.
Horizontal dilation is achieved by multiplying the independent variable x in the function by a positive constant a. If a > 1, the function is horizontally compressed, and if 0 < a < 1, the function is horizontally stretched. If a = 1, the function is not affected by horizontal dilation.
The function that represents a horizontal dilation of the function y = log x is a function of the form y = log(ax), where a is a positive constant. This is because changing the value of a will stretch or compress the graph horizontally.
A. h(x) = log(2x) + 1 represents a horizontal compression by a factor of 2, followed by a vertical translation upward by 1 unit.
B. K(x) = log(x + 1) represents a horizontal translation to the left by 1 unit.
C. f(x) = log(0.3x) represents a horizontal compression by a factor of 1/0.3 = 3.33.
D. g(x) = 5 log(x) represents vertical stretching by a factor of 5.
Therefore, the functions that represent a horizontal dilation of the function y = log x are A and C.

The rate of interest per annum will be 3.6%.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.
Given, Isabelle takes out a loan that gathers compound interest.
At the start, the loan amount is £5500
after the 1-year loan amount is £5698.00
After the 2-year loan amount is £5903.13
thus,
P = 5500
For t = 1 year A = 5698.00
since interest is annually thus, the value of n is 1
So, from the formula
5698 = 5500( 1 + r)
5500r = 5698 -5500
r = 198/5500
r = 0.036

A. Change y = 2x-3y- x' to polar form. Give exact values (no decimals) and show work. B. A certain tide repeats its cycle every 12 hours. High tide is 6 feet and low tide is 2 feet. High tide occurs a
A. The equation given can be expressed in polar form using the Pythagoras theorem.
Let the polar coordinate of a point be (r, θ).
Let r = √(x^2 + y^2)
=> r^2 = x^2 + y^2
=> r^2 = 2x^2 - 6xy - 2x
Let θ = tan^-1 (y/x)
Now, the equation in polar form is:
r^2 = 2x^2 - 6xy - 2x
tan^-1 (y/x) = θ
To find the exact values, solve the equation for the given values of x and y:
For x = 0 and y = 2:
r^2 = 0 - 6*2 - 0
=> r^2 = -12
=> r = √12
=> r = 2√3
tan^-1 (2/0) = θ
=> θ = 90°
Hence, the point (x, y) = (0, 2) has polar coordinates (2√3, 90°).
B. The given cycle has a period of 12 hours. This means that the time between each high and low tide is 12 hours. The height of high tide is 6 feet and the height of low tide is 2 feet. This means that the amplitude of the cycle is 4 feet (6 feet - 2 feet).
Hence, the equation for the tide cycle can be expressed as:
Height = 4sin (π/6 * t) + 4
Where t is time in hours.

Discounts are different types of price reductions or deductions from a product's cost. It is frequently employed in consumer transactions when consumers receive discounts on a range of goods. The % discount rate is provided.
Here the original price of picture = 120.00
Sale price after discount = 29.99 ≅ 30
Now using discount percent formula,
=> Discount percentage = (original price- sale price)/(original price)*100
=> Discount percentage = [tex]\frac{120-30}{120}\times 100=\frac{90}{120}\times100 = 75\%[/tex]
Hence the percentage of the discount is b)75%.

1. The arithmetic mean of the sample is: d. 3.50
To calculate the arithmetic mean, you need to add up all of the numbers in the sample and divide it by the total number of numbers in the sample. Using the given data, the total number is 20 (3+6+8+2=20). The total of the numbers in the sample is 31 (2+3+4+5=14). Therefore, the arithmetic mean of the sample is 31/20 = 3.50.
2. The average age of the children (x) is: c. 7.81
To calculate the average age of the children, you need to find the sum of the products of age and frequency (xf) and divide it by the total frequency (42). The sum of the products of age and frequency is 2628 (42+84+80+72+50=2628). Therefore, the average age of the children is 2628/42 = 7.81.
3. Standard deviation: a. 0.79
To calculate the standard deviation, you need to find the sum of the squares of the frequency multiplied by the square of the deviation (x²f) and divide it by the total frequency (42). The sum of the squares of the frequency multiplied by the square of the deviation is 6790 (252+588+640+648+500=6790). Therefore, the standard deviation is 6790/42 = 0.79.

Please help me!!! I need it very urgently
The angle LZW, given that angles Izw and Wzo are supplementary, would be an Obtuse angle.
How to find the angle type ?If the angles Izw and Wzo are supplementary, then their sum is equal to 180 degrees.
Since Wzo is an acute angle (meaning it measures less than 90 degrees), we know that Izw must be an obtuse angle, so that their sum is 180 degrees. An obtuse angle is an angle that measures greater than 90 degrees and less than 180 degrees. It is "obtuse" because it is more than a right angle (90 degrees), which is considered "sharp" or "acute".

The value of x in the sequence notation is 27/4
How to determine the value of xFrom the question, we have the following sequence that can be used in our computation:
[tex]\sum\limits^4_{j=-2} {2x(-\frac{3}{2})^j = \frac{1389}{32}[/tex]
When the above expression is expanded, we have the following equation
2x[(-3/2)⁻² + (-3/2)⁻¹ + (-3/2)⁰ + (-3/2)¹ + (-3/2)² + (-3/2)³ + (-3/2)⁴] = 1389/32
Evaluate the exponents the expressions
So, we have
2x[4/9 - 2/3 + 1 - 3/2 + 9/4 - 27/8 + 81/16] = 1389/32
Evaluate the fractions
2x * 463/144 = 1389/32
Evaluate the products
x * 463/72 = 1389/32
Solve for x
x = 72/463 * 1389/32
Evaluate
x = 27/4
Hence, the value of x is 27/4
