Hope this helped

Answer:

12.12436 or 7√3

Step-by-step explanation:

Answer:

x = - 3 - √33 / 2

x = + 3 + √33 /2

or

x=1.37228132...

x=−4.37228132...

Step-by-step explanation:

The two values of x that are roots of the equation x^2+3x-6=0 are approximately x ≈ -4.16 and x ≈ 1.16.

To find the two values of x that are roots of the equation x^2+3x-6=0, we can use the quadratic formula. The formula is:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = 3, and c = -6. Plugging in these values, we get:

x = (-3 ± √(3^2 - 4(1)(-6))) / 2(1)

Simplifying further:

x = (-3 ± √(9 + 24)) / 2

x = (-3 ± √33) / 2

So the two values of x that are roots of the equation are approximately x ≈ -4.16 and x ≈ 1.16.

Answer:

She makes $60 per hour

Step-by-step explanation:

There are 5 days in a week and 40 divided by 5 is 8 and 8x10=80 and 80 subtracted by 20 gives you 60.

Final answer:

After deducting childcare expenses, Sally's actual hourly wage is $7.50 per hour.

Explanation:

The original question is about calculating Sally's actual hourly wage after accounting for childcare expenses. Sally works 40 hours a week and earns $10 per hour. However, she incurs a cost of $20 per day for childcare. Assuming she works 5 days a week, her weekly childcare expenses are $20 x 5 = $100. Therefore, her weekly take-home pay after childcare is (40 hours x $10/hour) - $100 = $400 - $100 = $300. Now, to find Sally's actual hourly wage after childcare expenses, divide her take-home pay by the number of hours worked: $300 / 40 hours = $7.50 per hour.

All you have to do is just map out the coordinates yourself. You're looking for a reflection that goes across the Y axis, but NOT across the X axis.

Hope this helps you and anyone looking for an answer to their headache.

Final answer:

The reflected coordinates of the rectangle over the y-axis are L'(-1, -1), M'(-1, -9), N'(-8, -9), and O'(-8, -1), matching option 1.

Explanation:

The student is asking about finding the coordinates of a rectangle's vertices after it has been reflected over the y-axis. Reflecting a shape over the y-axis changes the sign of the x-coordinate of each vertex, while the y-coordinate remains the same. So, if we have a point (x, y), the reflected point over the y-axis would be (-x, y). Applying this to the rectangle's vertices we have:

For L(1, -1), the reflection L' would be (-1, -1).

For M(1, -9), the reflection M' would be (-1, -9).

For N(8, -9), the reflection N' would be (-8, -9).

For O(8, -1), the reflection O' would be (-8, -1).

Therefore, the correct reflected coordinates are L'(-1, -1), M'(-1, -9), N'(-8, -9), and O'(-8, -1), which corresponds to option 1.

The salesman's commission for selling a car at Sal's car shop is $901.50.

To calculate the salesman's commission for selling a car at Sal's car shop, we must first determine the sale price's profit margin over the dealership's purchase price. The profit is found by subtracting the purchase price ($16,235) from the selling price ($22,245).

Profit = Selling Price - Purchase Price
Profit = $22,245 - $16,235
Profit = $6,010

Next, we calculate the commission by taking 15% of the profit:

Commission = Profit * Commission Rate
Commission = $6,010 * 0.15
Commission = $901.50

Therefore, the salesman's commission for selling the car is $901.50.

a. The inequality that models the possible change in the number of feet, r, of the whale's elevation is: 35 - r ≤ 17.

This inequality represents the starting depth of 35 feet below the surface (35), minus the possible change in elevation (r), which should be less than or equal to the maximum height the whale jumps, which is nearly 17 feet above the surface (17).

b. By solving the inequality 35 - r ≤ 17, we can find the range of possible values for r.

First, subtract 35 from both sides of the inequality: -r ≤ 17 - 35. Simplifying further, we have -r ≤ -18. Then, multiply both sides by -1, remembering to reverse the inequality direction: r ≥ 18.

The solution to the inequality is r ≥ 18, meaning that the possible change in the number of feet of the whale's elevation must be equal to or greater than 18. This implies that the whale's jump cannot be less than 18 feet above the surface.

Therefore, the whale's elevation can change by any value equal to or greater than 18 feet, allowing it to jump to a height of nearly 17 feet above the surface.

a) The inequality can be written as 35 - r ≤ 17. b) The solution to the inequality is r ≥ 18, which means that the change in the number of feet, r, of the whale's elevation must be greater than or equal to 18.

a.

Since the whale swims upward and jumps to a height of nearly 17 feet above the surface, we can represent the change in elevation as r.

The inequality can be written as:

35 - r ≤ 17

Here, 35 represents the starting depth below the surface, and 17 represents the height above the surface that the whale reaches.

By subtracting r from the starting depth, we account for the possible decrease in elevation as the whale swims upward.

b. To solve the inequality, we can isolate r on one side of the equation:

35 - r ≤ 17

Adding r to both sides of the inequality:

35 - r + r ≤ 17 + r

35 ≤ 17 + r

Subtracting 17 from both sides:

35 - 17 ≤ 17 + r - 17

Simplifying further:

18 ≤ r

Therefore, the solution to the inequality is r ≥ 18.

In terms of the situation, the inequality r ≥ 18 means that the change in the number of feet, r, of the whale's elevation must be greater than or equal to 18.

This indicates that as the whale swims upward and jumps to a height of nearly 17 feet above the surface, the whale's elevation can increase by at least 18 feet from its starting depth of 35 feet below the surface.

The percent of vehicles whose speeds are between 65 miles/hour and 73 miles/hour will be 68 %.

It is given that mean speed of sample of vehicles (μ) is 69 miles/hour and standard deviation is 4 miles/hour.

We have to find out the percent of vehicles whose speeds are between 65 miles/hour and 73 miles/hour using the empirical rule.

What is the empirical rule if distribution lies within one standard deviation from the mean ?

The empirical rule states that for a normal distribution, 68% of the distribution are within one standard deviation from the mean.

As per the question , we have ;

Mean speed of sample of vehicles (μ) = 69 miles/hour

Standard deviation = 4 miles/hour

To find the % of vehicles , let's check where the distribution lies ;

So ;

μ - 4 ;

= 69 - 4

= 65 miles / hour

μ + 4 ;

= 69 + 4

= 73 miles / hour

Since ; it lies between μ - 4 and μ + 4 , so by using the empirical rule we get that it lies within one standard deviation.

Hence ; by the empirical rule ;

% of vehicles between speed 65 miles/ hour and 73 miles/hour = 68 %

Thus , the percent of vehicles whose speeds are between 65 miles/ hour and 73 miles/hour will be 68 %.

Final answer:

To simplify cotA/tanA, we recognize that cotA is the reciprocal of tanA. The expression simplifies to cosA^2/sinA^2, which can also be written as cotA^2.

Explanation:

To simplify the expression cotA/tanA, we can use the fundamental trigonometric identities that relate the cotangent and tangent functions. The cotangent function, cotA, is the reciprocal of the tangent function, tanA, which means cotA = 1/tanA. Therefore, when we simplify cotA/tanA, we are effectively dividing the reciprocal of the tangent function by the tangent function itself.
