For commission as a realtor, Michelle earns $349 plus 3% of the purchase price for each home she helps buy or sell. If she earned $8,965 in commission on a certain home, find its purchase price.
ANSWER:
$8965- $349= $8616
3/100x= 8616
8616 x 100/ 3= $287,200.
I'm posting this because somebody inboxed me asking for help and before I even got to help them, they deleted the inbox and i couldn't remember their name. I hope you see this and benefit from it, sorry!
Well, let us solve this step by step.
We know that Michelle earns 349 plus 3% of the Purchase price. Let us call the Purchase price as P, so that:
Earnings, E = 349 + 0.03 P
So if she earns 8,965 (E = 8,965) so we can find P:
8,965 = 349 + 0.03 P
0.03 P = 8,616
P = $287,200
Michelle's total commission from a house sale was $8,965, from which $349 is a fixed commission. The rest, $8616, represents the 3% of the selling price of the house. By solving the simple equation $8616 = 0.03 * X, we find that the home price is $287,200.
Explanation:This problem is a simple, but common, practice in the world of linear equations. The first step is to understand that the base commission of $349 is a constant that Michelle earns every time, whilst the remaining part of her commission comes from the 3% percentage of the sale price. After subtracting the base commission from the total commission, we get a value of: $8965 - $349 = $8616. This value is equal to 3% of the house price.
We can express this as: 8616 = 0.03 * X, where X is the value of the house. By isolating X (the house price), we divide both sides by 0.03 to get the house price. Therefore, the home price would be $8616 / 0.03 = $287,200.

Consider the solid shaped like an ice cream cone that is bounded by the functions z=x2+y2‾‾‾‾‾‾‾√ and z=50−x2−y2‾‾‾‾‾‾‾‾‾‾‾‾√. set up an integral in polar coordinates to find the volume of this ice cream cone.
To calculate the volume of a solid bounded by two functions, set up an integral in polar coordinates. The volume is found by integrating the difference of the two volumes described by the functions (50 - sqrt(x²+y²) - sqrt(x²+y²)) over r, θ, and z within their appropriate limits.
Explanation:The subject of the question is mathematics, more specifically, integral calculus in spherical or polar coordinates. Calculating the volume of a solid bounded by two functions can be done by taking the difference of the two function volumes.
The integrals, using polar coordinates (r and θ), are set up as follows:
Volume = ∫∫∫(50 - sqrt(x²+y²) - sqrt(x²+y²)) r dr dθ dz,
where the limits for r are [0, sqrt(50)], for θ are [0, 2π], and for z are [0, 50]. Also, note that 'x²+y²' is replaced with 'r²' because in polar coordinates, 'r' represents the square root of x^2 plus y^2.
This integral, when solved, gives the volume of the ice cream cone-shaped solid.

The volume of the ice cream shaped solid can be found by converting the limits of the cone to polar coordinates and performing a double integral. The limits of the cone are represented by the expressions z = r and z = sqrt(50 - r^2). The volume integral will be ∫ _(theta=0 to 2*pi) ∫ _(r=0 to sqrt(50)) [(sqrt(50 - r^2)) - r] r dr dθ.
Explanation:To evaluate the volume of the solid resembling an ice cream cone, we can use the method of double integration in polar coordinates. Because we're dealing with a cone, polar coordinates are suitable as they're related to circular symmetry.
The limits of the cone are given by the functions z = sqrt(x^2 + y^2) and z = sqrt(50 - x^2 - y^2). In polar coordinates these become z = r and z = sqrt(50 - r^2).
To evaluate the volume of the cone, we need to subtract the volume of the lower cone (given by z = r) from the volume of the upper cone (given by z = sqrt(50 - r^2)). We convert the values to polar coordinates and use double integration as follows:
V = ∫ _(theta=0 to 2*pi) ∫ _(r=0 to sqrt(50)) [(sqrt(50 - r^2)) - r] r dr dθ
This integral, once solved, will give the volume of the ice cream shaped solid.

Find all the second partial derivatives. v = e5xey
Final answer:
The second partial derivatives of v = e⁵x * ey are ∂²v/∂x² = 25e⁵x * ey and ∂²v/∂x² = 5e⁵x * e^y.
Explanation:
To find the second partial derivatives of the function v = e⁵x * ey, we need to differentiate twice with respect to x and y. Let's start with the first partial derivative with respect to x:
∂v/∂x = ∂(e⁵x * ey)/∂x
= 5e⁵x * ey
Next, we differentiate the first partial derivative with respect to x to find the second partial derivative with respect to x:
∂²v/∂x² = ∂(5e⁵x * ey)/∂x
= 25e⁵x * ey
Similarly, the second partial derivative with respect to y is:
∂²v/∂x² = ∂(5e⁵x * ey)/∂y
= 5e⁵x * e^y

It's the holiday season and you are working for a packing company that specializes in holiday fruit cakes. For Christmas this year, the number of clients requesting fruit cakes has more than tripled and orders need to be shipped prior to the New Year. Your supervisor has asked you to work 15 hours more than a normal 40 hour work week, including Christmas day, which falls on a Friday. Therefore, one of your regular 8 hour days will be paid at the holiday rate. You get paid $10.00 per hour plus you get time and a half for overtime and double pay for the holidays. What will your gross base pay be for the week?
Normal rate: $10/hr
Time and a half= $15/hr
Double pay: $20/hr
Hours to be paid at $10/hr =32 hours
$10/hr x 32hrs= $320
$20/hr x 8hrs= $160
$15/hr x 15hrs=$225
Total gross pay: $705
To calculate your gross base pay for the week working extra hours including a holiday, you need to consider regular pay, overtime pay, and holiday pay. The gross base pay for the week will be $785.00.
Explanation:To calculate your gross base pay for the week, you need to consider your regular hours, overtime hours, and holiday pay. Here's how you can calculate it:
Calculate your regular pay for the 40 hours of work at the regular rate: $10.00 per hour x 40 hours = $400.00.Calculate your overtime pay for the 15 additional hours of work at time and a half: $10.00 per hour x 1.5 = $15.00 per hour. $15.00 per hour x 15 hours = $225.00.Calculate your holiday pay for the 8-hour day at double the regular rate: $10.00 per hour x 2 = $20.00 per hour. $20.00 per hour x 8 hours = $160.00.Add up your regular pay, overtime pay, and holiday pay: $400.00 + $225.00 + $160.00 = $785.00.Therefore, your gross base pay for the week will be $785.00.

One side of a right triangle is known to be 9 cm long and the opposite angle is measured as 30°, with a possible error of ±1°. (a) use differentials to estimate the error in computing the length of the hypotenuse. (round your answer to two decimal places.)
To estimate the error in the hypotenuse length of a right triangle using differentials, we use the trigonometric identity sin(θ) = opposite/hypotenuse, finding the derivative, and then apply the angle error to get an error estimate of
±0.31 cm in the hypotenuse length.
The question asks to use differentials to estimate the error in computing the length of the hypotenuse of a right triangle when one side is 9 cm and the opposite angle is 30° with a possible error of ±1°. To calculate the hypotenuse (c) when dealing with problems involving right triangles, you can use the trigonometric identity sin(θ) = opposite/hypotenuse, which can be rearranged to c = opposite/sin(θ). The differential of c with respect to θ is dc/dθ = -opposite * cos(θ)/sin2(θ). Given that the opposite side is 9 cm and the angle θ is 30°, we can find dc/dθ and then multiply by the possible angle error of ±1° to estimate the error in the hypotenuse length.
Plugging in the given values and converting the angle to radians (since the derivative is taken with respect to radians), we find
dc/dθ ≈ -9 cm × cos(30°)/sin2(30°) ≈ -18 cm.
The possible change in angle is ±1°, which in radians is approximately ±0.0175 radians, thus
Estimated error in hypotenuse ≈ -18 cm × ±0.0175 ≈ ±0.315 cm.
Therefore, the estimated error in the length of the hypotenuse, rounded to two decimal places, is ±0.31 cm.

Two triangles have side lengths 3, 4, 5 and 6, 8, 10, respectively. The triangles are similar to each other.
The missing side length of the second triangle is 8.
To find the missing side length of the second triangle, we can use the property that similar triangles have proportional side lengths.
Given:
First triangle: ( 3, 4, 5 )
Second triangle: ( 6, x, 10 )
Since the triangles are similar, the ratios of corresponding sides are equal:
[tex]\[ \frac{6}{3} = \frac{x}{4} = \frac{10}{5} \][/tex]
From the first ratio, [tex]\( \frac{6}{3} = \frac{x}{4} \)[/tex], cross multiply:
[tex]\[ 6 \times 4 = 3 \times x \][/tex]
[tex]\[ 24 = 3x \][/tex]
Divide both sides by 3 to solve for ( x ):
[tex]\[ x = \frac{24}{3} \][/tex]
[tex]\[ x = 8 \][/tex]
So, the missing side length of the second triangle is 8.
Here's a detailed calculation step-by-step:
1. Set up the ratios of corresponding sides: [tex]\( \frac{6}{3} = \frac{x}{4} = \frac{10}{5} \).[/tex]
2. Use the first ratio to find [tex]\( x \): \( 6 \times 4 = 3 \times x \)[/tex].
3. Solve for [tex]\( x \): \( 24 = 3x \)[/tex].
4. Divide both sides by 3: [tex]\( x = \frac{24}{3} = 8 \)[/tex].
5. Therefore, the missing side length of the second triangle is 8.

Graph parallelogram ABCD on a coordinate plane with vertices A(3,4) B(6,1) C(0,-2) and D(-3,1).
Find the slope of each side.
What do you notice about the slopes?
A parallelogram, the opposite sides have equal slopes.
To graph the parallelogram ABCD on a coordinate plane, we can plot the given points A(3,4), B(6,1), C(0,-2), and D(-3,1), and then connect them in order to form the parallelogram.
Here are the steps to find the slope of each side:
Plot the Points:
Plot the points A(3,4), B(6,1), C(0,-2), and D(-3,1) on the coordinate plane.
Connect the Points:
Connect the points in order (A to B to C to D to A) to form the parallelogram.
Find the Slope:
The slope of a line passing through two points
(x_1 ,y_1 ) and (x_2 ,y_2 ) is given by the formula m= y_2 -y_1/ x_2- x_1
Calculate the slope for each pair of consecutive points:
Slope of AB: mAB = 1−4/6−3
Slope of BC: mBC = −2−1/0−6
Slope of CD: mCD = 1−(−2)/−3−0
Slope of DA: mDA = 4−1/ 3−(−3)
Now, observe the slopes:
mAB and mCD
are the slopes of opposite sides. They should be equal for a parallelogram.
mBC and mDA are the slopes of the other pair of opposite sides. They should also be equal for a parallelogram.
So, for a parallelogram, the opposite sides have equal slopes.
