A coat is marked down by 10% and the customer is given a second discount of 25% what is the sales price
The sales price of the coat is 67.5% of the original price
How to determine the sales price of the coat ?From the question, we have the following parameters that can be used in our computation:
Markdown rate = 10%
Second discount = 25%
The retail price of the coat can be calculated using the following equation
Retail price = original price * (1 - Markdown rate) * (1 - discount)
Substitute the known values in the above equation, so, we have the following representation
Retail price = original price * (1 - 10%) * (1 - 25%)
Evaluate the products
Retail price = original price * 0.675
Rewrite as
Retail price = 67.5% of the original price
Hence, the sales price is 67.5% of the original price

What is maxima of a function?
Maxima of a function gives the maximum value of a function in a given interval or within the whole domain.
f(x, y) = [tex]y\sqrt{x} -y^2 -3x + 11y[/tex]
[tex]f_x(x, y) = \frac{y}{2\sqrt{x}} - 3[/tex]
[tex]f_y(x, y) = \sqrt{x} - 2y +11[/tex]
Putting x = 0 in [tex]f_y(x, y) = 0[/tex],
-2y + 11 = 0
[tex]y = \frac{11}{2}[/tex]
[tex](0, \frac{11}{2})[/tex] is a critical point
Putting [tex]f_x(x, y) = 0[/tex] and [tex]f_y(x, y) = 0[/tex]
[tex]\frac{y}{2\sqrt{x}} - 3 = 0\\\frac{y}{2\sqrt{x}} = 3\\y = 6\sqrt{x}[/tex]
[tex]\sqrt{x} - 2y+11 = 0\\\sqrt{x} -2\times 6\sqrt{x}+11=0\\\sqrt{x}-12\sqrt{x} + 11 = 0\\11\sqrt{x} = 11\\\sqrt{x} = \frac{11}{11}\\\sqrt{x} = 1\\x = 1[/tex]
When x = 1, y = [tex]6 \times \sqrt{1} = 6[/tex]
(1, 6) is a critical point
[tex]f_{xx}(x, y) = -\frac{1}{4}x^{-\frac{3}{2}}[/tex]
[tex]f_{yy} = -2[/tex]
[tex]f_{xy} = \frac{1}{2\sqrt{x}}[/tex]
The point (0, [tex]\frac{11}{2}[/tex]) is undefined in the second order partial derivative
For the critical point (1, 6)
[tex]f_{xx}(1, 6) = -\frac{1}{4}\\f_{yy}(1, 6) = -2\\f_{xy}(1, 6) = \frac{1}{2}[/tex]
[tex]f_{xx}f_{yy}-(f_{xy})^2[/tex]
[tex]-\frac{1}{4}\times -2-(\frac{1}{2})^2\\\frac{1}{2} - \frac{1}{4}\\\frac{1}{4} > 0[/tex]
[tex]f_{yy} = -2 < 0[/tex]

Step-by-step explanation:
Answer:Centroid I hope this helpful to you mark me brainlist if correct
Step-by-step explanation:
Hence, the correct statement is "The Centroid of a triangle is located 2/3 of the distance from each vertex to the midpoint of the opposite side."The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangleCentroid theorem: the distance between the centroid and its corresponding vertex is twice the distance between the barycenter and the midpoint of the opposite side. That is, the distance from the centroid to each vertex is 2/3 the length of each median. This is true for every triangleThe centroid of a triangle is the intersection of the three medians of the triangle (each median connecting a vertex with the midpoint of the opposite side).

Find an equation for the parabola that has its vertex at the origin and has its focus at the point: ( − 7.32 , 0 ) .
Step-by-step explanation:
1.What is the equation of a parabola with a vertex at (0, 0)?
y = ax²; y = -ax²; x = ay²; x = -ay² where a = [½, 1 , 2]
Also an infinity of others at various values of a and various angles.
2.The focus lies above the vertex, so the parabola is vertical and the focal length p=10.25
Equation for up-opening parabola with vertex (h,k) and focal length p:
y=14p(x−h)2+k
y=14p(x−0)2+0y=141x2
3.Since the directrix is the line y=−10.25 , a point (x,y) is on the parabola if, and only if,
x2+(y−10.25)2=(y+10.25)2.
Therefore, x2−20.5y=20.5y and y=141x2.

What is slope?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line.
The ratio of "vertical change" to "horizontal change" between two different points on a line is calculated using the slope of a line formula.
We will comprehend the slope-finding method and its applications in this article.

Write the equation of the line passing through the points (0, 0), (2, 1), and (-2, − 1).
Answer:
y = 0.5x
Step-by-step explanation:
Slope = m = (2-0)/(1-0) = 1/2 or 0.5
y-intercept = b = 0 since it passes through (0,0)
Slope-Intercept form of a line is y = mx + b

Carol had four times as many coins as Eli had, or a 4:1 ratio.
What is ratio?An ordered pair of integers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, if there is 1 male and 3 girls, you may express the ratio as 1: 3 (there are 3 girls for every guy), meaning that there are 1 in 4 boys and 3 in 4 girls. A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
Here,
Dan has twice what Eli has ( D= 2 x E )
Carol had twice what Dan had ( C = 2 x D )
for example , let's suppose Eli had 2 coins
this means Dan had 4 coins,

II The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-um thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is .2x10^-11m^2/s Give your answer to 1 significant figure.
The diffusion time of the red blood cell to take oxygen through the membrane is 25uS.
The small capillaries in the lungs are in close contact and it takes a red blood cell 0.5 seconds to squeeze through the capillary.
The diffusion time for the oxygen across the 1 um thick membrane separating the air is given by,
t = x²/2D
Where,
t is the diffusion time,
x is the thickness of the membrane,
D is the diffusion coefficient.
Putting values,
t = (1 x 10⁻⁹)²/2 x 2 x 10⁻¹¹
t = 10⁻⁷/4
t = 25 x 10⁻⁹ seconds.
t = 25 uS.

We know that Maya's earnings will be $498 for working 41 hours using simple mathematical operations.
What do we mean by mathematical operations?A rule that specifies the right procedure to follow while evaluating a mathematical equation is known as the order of operations.
Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction are the steps that we can remember in that order using PEMDAS (from left to right).
So, earnings of Maya when she works for 41 hours are:
We know that Maya works for $12.00 per hour.
She's paid 1.5 times her hourly income when she works for more hours after 40 hours.
That will be: 12 × 1.5 = $18
Hence, Maya's income for 41 hours will be:
40 hours + 1 hour (Extra hour)
(12 × 40) + 18
480 + 18

What are the solutions to the linear system?
The solution to a system of linear equations is the point that lies on both lines. In other words, the solution is the point where the two lines intersect
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
How do you determine a linear system?
Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear. If your equation has no exponents, it is linear
Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such that it does not form a straight line. It looks like a curve in a graph and has a variable slope value.
