The endpoints of the other diagonal are (-2, 2) and (-6, 8).
Distance formula, Algebraic expression that gives the distances between pairs of points in terms of their coordinates (see coordinate system). In two- and three-dimensional Euclidean space, the distance formulas for points in rectangular coordinates are based on the Pythagorean theorem.
Given we have a rhombus with endpoints (-10, 1) and (2, 9)
So as we already know, a rhombus is a parallelogram whose sides are equal, so the distance from say (-10, 1) to either endpoint of the other diagonal must be the same.
Distance between 2 points [tex]$\mathrm{d}=\sqrt{[-2-(-10)]^2+[2-1]^2} \Longrightarrow d=\sqrt{(-2+10)^2+(2-1)^2}$$\mathbf{d}=\sqrt{\mathbf{6 4 + 1}} \Longrightarrow d=\sqrt{65}$[/tex]
While solving with other coordinate we get [tex]$\mathbf{d}=\sqrt{(-6+10)^2+(8-1)^2}[/tex]
[tex]$\mathrm{d}=\sqrt{16+49}\\\Longrightarrow d=\sqrt{65}$[/tex]

find the exact trigonometric ratios for the angle x whose radian measure is given. (if an answer is undefined, enter undefined.) 27???? 4
The exact trigonometric ratios for the angle x is second quadrant.
Given Radian equals to θ = 27π / 4, we need to find all the Trigonometric ratios for the same -
Lets calculate the value of θ first.
We know π equals 180 degree angle and 2π equals 360 degree, hence with each 2π the radian moves back to zero degree. Which means
θ = 27π / 4 can be reduced to θ = 3π / 4
Hence θ = 135 degree which can be represented as below -
As This lies in second quadrant, hence on x-axis (Value of base , needs to be taken as -1)
sin θ = 1/√2 cosec θ = √2
cos θ = -1/√2 sec θ = - √2
tan θ = -1 cot θ = - 1
What is trigonometric ratios?Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions.

Write an equation for a line that is perpendicular to the line given by x=9 and passes through the point (-6,-3)
Answer:
y = -3
Step-by-step explanation:
We are given an equation of the line, x=9.
And we want to write another equation of the line that is perpendicular to x=9 and passes through (-6, -3).
There are 3 ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept. Standard form, which is ax+by=c, where a, b, and c are integer coefficients, but a and b cannot be 0, while a also cannot be negative.Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Any one of these forms would work, but let's use slope-intercept form, as it is the most common way to write the equation of the line.
Perpendicular lines have slopes that multiply to get -1. They are also considered negative and reciprocal. For example, 5 and -1/5 would be the slopes of perpendicular lines.
So, let's find the slope of x=9.
If a line is written like x=9, it means that when it is graphed, it will be a vertical line, and a vertical line has an undefined slope.
As you may know, [tex]\frac{1}{0}[/tex] is also considered to be undefined. This means that the slope of this vertical line can be written as [tex]\frac{1}{0}[/tex].
Now, let's get the reciprocal of this slope (put the value of the numerator on the denominator and vice versa), then add a minus sign after it.
[tex]\frac{1}{0}[/tex] => [tex]-\frac{0}{1}[/tex] => 0
The slope of the line we're writing is 0.
We can replace m in y=mx+b with 0.
y = 0x + b
Now we need to find b.
As the equation passes through the point (-6,-3), we can use its values to help solve for b.
Substitute -6 as x and -3 as y in the equation.
-3 = 0(-6) + b
Multiply.
-3 = b
Replace b with -3 in the equation.
y = 0x - 3
This can also be written as:
y = -3

per gallon, the cost of all the ingredients in your stew is $2.76. you consistently sell 57 gallons of stew per week for $435.98 in total sales. what is your food cost percentage?
The cost percentage is 3.61 %.
A cost is the worth of money that has been expended in the production or delivery of a good or service and is therefore no longer accessible for use in accounting, retail, research, or accounting.
A percentage is calculated by dividing a value or a number by its sum, then multiplying the result by 100. The percentage calculation formula is ( value / total value) × 100%.
The cost of all ingredients mixed in the stew is $2.76.
The total sales is $435.98.
57 gallons of stew are sold per week.
Therefore, the total sales per week is
= $2.76 × 57 = $157.32
Hence, the cost percentage of food is:
= ( 2.76 × 57 ) / 435.98
= 157.32 / 435.98
= 0.361
= 3.61 %

Let Ca be the function for Plan A and Cb the function for Plan B.
According to the problem statement, we can conclude that:
Ca(n) = 3n + 8Cb(n) = 5nwhere C is the cost and n is the number of videos
Cost that the user will pay for having watched n videos
Ca = cost of Plan A
Cb = cost of Plan B
Is there any point (n) that Ca will be equal to Cb??? Let's equate the functions to check if there is a common point and if there is, what would it be.
Ca = Cb
3n + 8 = 5n
2n = 8
n = 4
In n = 4 we have a condition for the cost that does not matter Ca or Cb.
I will present 2 ways to solve:
1 - building the graph of the functions and observing the points where the Y axis (cost axis) its smaller
2 - assigning 2 points - below n = 4 and above n = 4 - to observe the cost behavior
1 - see attachment
2 - let's choose the points n = 1 and n = 10 (as already said, n=4 does not matter Ca or Cb - meeting point / intersection point)
n = 1
Ca(1) = 3.1 + 8 = 11
Cb(1) = 5.1 = 5
Ca > Cb, then Cb better to the user
n = 10
Ca(10) = 3.10 + 8 = 38
Cb(10) = 5.10 = 50
Ca < Cb, then Ca better to the user
We can come to the following conclusion:
0 < n < 4 → better use Plan B (in this interval the cost to the user will be lower with Plan B)
n = 4 → It doesn't matter to use Plan A or Plan B.
n > 4 → better use Plan A (for n above 4 the cost to the user will be lower with Plan A)

For instance, 650,000,000 can be represented as 6.5 108 in scientific notation.Scientific notation consists of a coefficient multiplied by 10 raised to an exponent . To convert to a real number, start with the base and multiply by 5 tens like this: 5.14 × 10 × 10 × 10 × 10 × 10 = 514000(here are only 4 zeros because you cancel one zero to remove decimal) so we write 5.14*10^5 to convert from 5.14*10^5.

Which equation is correctly rewritten to solve for x?An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given the equation in the question;
-fx - g = h
Solve for x.
To solve for x simply means to make x the subject of the formula or equation.
-fx - g = h
Add g to both side
-fx - g + g = h + g
Negative g and positive g cancels out.
-fx = h + g
Now, divide each term in the equation by the coefficient of x
-fx/-f = h/-f + g/-f
x = -h/f + (-g/f)
x = -h/f - g/f

After you have this, you want to get x on its own. To do this, divide both sides of the inequality by 3 to get x < -6
2) 2x + 23 [tex]\leq[/tex] 11
For this one, we use the same steps. First, subtract 23 from both sides to isolate 2x, giving us 2x [tex]\leq[/tex] 11 - 23, which we simplify down to 2x [tex]\leq[/tex] -12.
From here, we divide both sides of the inequality by 2 to get x on its own. This gives us x [tex]\leq[/tex] -6
