The expression 0.85(1.4s) represents the final selling price of the jacket after two price changes: an initial 15% decrease in price, followed by another 15% decrease in price.

The expression 0.85(1.4s) represents the final selling price of the jacket after two price changes. We can break it down into its constituent parts to understand what happened to the price.

Factor 1.4s represents the original selling price of the jacket. This means that the store owner started with a price of 1.4s dollars.

The factor 0.85 represents the first price change. When the store owner lowered the price by 15%, the new price became 0.85 times the original price.

The second factor of 0.85 represents the second price change. After the first price change, the new price was 0.85(1.4s) dollars. When the store owner lowered the price again by 15%, the final selling price became 0.85 times the price after the first price change.

The problem involves finding the radius of a cylindrical can that will minimize the cost of the metal to make the can, given that the can must hold one liter of oil.

Specifically, we need to find the radius of the can that will minimize the surface area, and hence the cost, of the metal required to make the can.

To solve the problem, we need to first write an expression for the surface area of the can in terms of its radius, and then differentiate this expression with respect to the radius to find the critical point. We then need to check that the critical point corresponds to a minimum value of the surface area, which will give us the optimal radius for the can. Optimization problems like this one are used in many fields, including engineering, economics, and physics, to find the best course of action given certain constraints and objectives.

The first step in solving the equation is to isolate the radical term, and the second step is to eliminate the radical by raising both sides to the power of 3. Solving this equation for x initially yields x = 0, x = 2, and x = -2. Checking the solutions shows that it is not a real solution.

The first step in solving the equation (4x)[tex]^{1/3}[/tex] - x = 0 is to isolate the radical term by adding x to both sides of the equation. This gives us

(4x)[tex]^{1/3}[/tex]= x.
The second step is to raise both sides of the equation to the power of 3, which eliminates the radical. This results in 4x = x³.

Solving this equation for x initially yields x = 0, x = 2, and x = -2.
Checking the solutions shows that only x = 2 is a valid solution, as plugging it back into the original equation yields (4*2)[tex]^{1/3}[/tex] - 2 = 0. However, plugging in x = 0 results in a division by zero, and plugging in x = -2 yields a negative number under the radical, which is not a real solution.

Answer:

(2,-4)

Step-by-step explanation:

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

2x+3y=−8,3x+y=2

To make 2x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by 2. Then simplify

6x+9y=−24,6x+2y=4

Add 6x to −6x. Terms 6x and −6x cancel out, leaving an equation with only one variable that can be solved, add 9y to −2y, add −24 to −4, and divide both sides by 7.

y=−4

Substitute −4 for y in 3x+y=2. Because the resulting equation contains only one variable, you can solve for x directly. Add 4 to both sides of the equation and divide both sides by 3.

The value of the test statistic z is approximately -2.12. The Option D is correct.

To test the hypothesis that the mean wrist breadth of men is equal to 9 cm, we will use a one-sample z-test.

The null hypothesis is: H0: µ = 9 cm

The alternative hypothesis is: Ha: µ ≠ 9 cm

We are given a sample of n = 72 men with a sample mean of x = 8.91 cm and a population standard deviation = 0.36 cm.

The test statistic for a one-sample z-test is given by: z = (x - µ) / (o / sqrt(n))

Substituting the given values, we get:

= (8.91 - 9) / (0.36 / sqrt(72))

z = -2.119

At a significance level of a = 0.01, the critical values for a two-tailed test are ±2.576.

Since our test statistic (-2.119) falls outside of this range, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the mean wrist breadth of men is not equal to 9 cm.

To move triangle KLM so that point K lies on the Y-axis, you need to apply a translation that shifts the entire triangle horizontally. By translating triangle KLM using the vector (-4, 0), point K now lies on the Y-axis.

To move the triangle so that point K lies on the Y axis, we need to perform a translation. First, we need to determine how far point K is from the Y axis. We can do this by finding the x-coordinate of point K, which is 4. This means that point K is 4 units away from the Y axis.

Next, we need to determine the direction of the translation. Since we want to move point K onto the Y axis, we need to move the triangle in the negative x direction. Therefore, the translation that will move the triangle so that point K lies on the Y axis is a horizontal translation of -4 units. We can express this translation as follows:

T(-4, 0)

This means that we need to move each point of the triangle 4 units to the left (negative x direction) to achieve the desired position of point K on the Y axis.

The equation of the line that is perpendicular to y = -8x + 2 and contains the point (-4, 1) is y = (1/8)x + (3/2).

To find the equation of the line that is perpendicular to y = -8x + 2 and contains the point (-4, 1), first, determine the slope of the given line. The slope is -8. Perpendicular lines have slopes that are negative reciprocals of each other, so the slope of the new line will be 1/8.

Now, use the point-slope form of a linear equation, y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point (-4, 1). Plug in the values: y - 1 = (1/8)(x - (-4)).

Simplify the equation: y - 1 = (1/8)(x + 4). Distribute the 1/8: y - 1 = (1/8)x + (1/2). Finally, add 1 to both sides: y = (1/8)x + (1/2) + 1.

So, the equation of the line that is perpendicular to y = -8x + 2 and contains the point (-4, 1) is y = (1/8)x + (3/2).

Answer:

48 adult tickets were sold.

Step-by-step explanation:

Let's use algebra to solve this problem:

Let's define:

From the problem statement, we know:

We can use the first equation to solve for x in terms of y:

x = 320 - y

Substituting this expression for x into the second equation, we get:

3(320 - y) + 8y = 1200

Expanding the left side, we get:

960 - 3y + 8y = 1200

Simplifying, we get:

5y = 240

Solving for y, we get:

y = 48

Therefore, 48 adult tickets were sold.

Additional:

To find the number of student tickets sold, we can substitute y=48 into the first equation:

x + 48 = 320

x = 272

Therefore, 272 student tickets were sold.

The given integral is ∫₁₀ (10/(x-2)) dx.

The given integral is divergent and the answer is "oo".

To see why the integral is divergent, we can use the following limit comparison test:

∫₁₀ (10/(x-2)) dx ~ ∫₁₀ (1/x) dx, as x → 2.

The symbol "~" means "is asymptotic to". We can use this comparison because as x approaches 2 from the right, the function 10/(x-2) approaches positive infinity.

Now, we know that the integral ∫₁₀ (1/x) dx diverges because the improper integral of 1/x from 1 to infinity diverges. Therefore, by the limit comparison test, the original integral is also divergent.

Hence, the given integral ∫₁₀ (10/(x-2)) dx is divergent, and the answer is "oo".

The time between buses arriving at the stop follows an exponential distribution with a mean of 26 minutes.

To find the probability of waiting at least 4 minutes for the bus, we can use the cumulative distribution function (CDF) of the exponential distribution:

P(waiting at least 4 minutes) = 1 - P(waiting less than 4 minutes)

The probability of waiting less than 4 minutes can be calculated using the CDF:

P(waiting less than 4 minutes) = 1 - e^(-4/26) ≈ 0.146

Therefore, the probability of waiting at least 4 minutes for the bus is:

P(waiting at least 4 minutes) = 1 - 0.146 ≈ 0.854

The probability that the word so formed starts with M is 1/6, and the probability that it starts with M and ends with E is 1/30.

i) To find the probability that the word starts with M, we need to consider the total number of possible arrangements of the letters and the number of arrangements that start with M. The word "MOBILE" has 6 letters, so there are 6! = 720 possible arrangements of the letters. To find the number of arrangements that start with M, we can fix the M in the first position and arrange the remaining 5 letters in the remaining positions, which gives us 5! = 120 arrangements. Therefore, the probability that the word starts with M is:

P(starts with M) = number of arrangements that start with M / total number of arrangements

= 120 / 720

= 1/6

ii) To find the probability that the word starts with M and ends with E, we can fix the M in the first position and the E in the last position, and then arrange the remaining 4 letters in the remaining positions. This gives us 4! = 24 arrangements. Therefore, the probability that the word starts with M and ends with E is:

P(starts with M and ends with E) = number of arrangements that start with M and end with E / total number of arrangements

= 24 / 720

= 1/30

Thus, the probability that the word so formed starts with M is 1/6, and the probability that it starts with M and ends with E is 1/30.

The value of sec(θ) = 4

The value tan(θ) = ±√15

The value of cot(θ) = ±√15/15

We can use the identity sec²(theta) - 1 = tan²(theta) to find the value of tan(theta).

Given sec(θ) = 4, we have:

sec²(θ) = 4² = 16

Then, using the identity:

tan²(θ) = sec²(θ) - 1 = 16 - 1 = 15

Taking the square root of both sides, we get:

tan(θ) = ±√(15)

Since sec(θ) is positive, we know that cos(theta), which is the reciprocal of sec(θ), is also positive. This tells us that θ is in the first or fourth quadrant, where sin(θ) is also positive.

Therefore:

sin(θ) = √(1 - cos²θ))

= √(1 - (1/16))

= √15/16)

= √(15))/4

Using the reciprocal identities, we can find the values of csc(θ) and cot(θ):

So the triangle is a right triangle. The angle is next to one of the given sides. "Next to" is called "adjacent" these mean the same thing. One side is adjacent to the angle. The other given side is the hypotenuse.

The trig function that puts together Adjacent and Hypotenuse is cosine.

cos (angle) = adj/hyp

We know the two sides. Fill them in.
