As per the Pythagoras theorem, there are totally 4 triangles possible.
Pythagoras theorem:
In geometry, Pythagoras theorem states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs.
Given,
Here we need to find how many (non-congruent) isosceles triangles exist which have a perimeter of 10 and integer side lengths.
As per the Pythagoras theorem, we know that the sum of two sides should be greater than the third.
And here we have the isosceles triangles, then the value of two side of the triangle is equal.
Here the perimeter of the triangle is 10.
Then the values must be the sum of 10,
=> 2, 6, 2
=> 1, 1, 8
=> 3, 3, 4
=> 4, 4, 2
These are the possible combinations.

Find an equation for the line that passes through the points (-5,1) and (1,3) .
The equation of the line that passes through the points (-5,1) and (1,3) is x - 3y = -8
Determining the equation of a line that passes through a set of pointsFrom the question, we are to determine the equation of the line that passes through the given points.
The given points are (-5, 1) and (1, 3)
Using the formula,
(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)
Then,
(y - 1) / (x - (-5)) = (3 - 1) / (1 - (-5))
Simplify
(y - 1) / (x + 5) = 2 / (1 + 5)
(y - 1) / (x + 5) = 2 / 6
(y - 1) / (x + 5) = 1/3
Cross multiply
3(y - 1) = 1(x + 5)
3y - 3 = x + 5
x + 5 = 3y -3
x - 3y = -3 - 5
x - 3y = -8
Hence, the equation is x - 3y = -8

Suppose that R(x) is a polynomial of degree 13 whose coefficients are real numbers.
Also, suppose that R(x) has the following zeros.
2, -4, 3i, -4+i
Answer the following.
(a) Find another zero of R(x).
(b) What is the maximum number of real zeros that R(x) can have?
(c) What is the maximum number of nonreal zeros that R(x) can have?
Answer:
(a) Other zeros: 3i and -4-i
(b) 9
(c) 10
Step-by-step explanation:
Given information:
Polynomial function with real coefficients.Degree: 13Zeros: 2, -4, 3i, -4+iPart (a)For any complex number [tex]z=a+bi[/tex], the complex conjugate of the number is defined as [tex]z^*=a-bi[/tex] .
If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.
Therefore, if R(x) is a polynomial with real coefficients, and 3i is a root of R(x)=0, then its complex conjugate -3i is also a root of R(x)=0.
Similarly, if -4+i is a root of R(x)=0, then its complex conjugate -4-i is also a root of R(x)=0.
Part (b)The degree of the polynomial is the greatest of the exponents of its various terms.
The degree of R(x) with just the given roots (including the complex conjugates) is 6, which includes 2 real zeros.
As the actual degree of R(x) is 13, the maximum number of real zeros would be 7 more than the given real zeros.
Therefore, the maximum number of real zeros that R(x) can have is 9.
Part (c)For each complex root there is also a complex conjugate root.
We have been given 2 complex zeros and 2 real roots, so when we include the complex conjugates, the degree of R(x) is 6.
The actual degree of R(x) is 13, so the maximum number of non-real zeros is 6 more (as they come in pairs) than the already given 4 non-real zeros. Therefore, the maximum number of non-real zeros that R(x) can have is 10.

Step-by-step explanation:
We need two easy-to-read points on grid intersections.
Look at the point on the y-axis. It is (0, 3).
Now go up to the right until you find the next easy-to-read point.
It is (3, 4) which is on a grid intersection.
gradient = run/rise
rise = distance in y (vertical distance)
run = distance in x (horizontal distance)
We start at (0, 3) and go to (4, 4) by going only vertically and horizontally.
From (0, 3), go 1 unit up. That is a rise of 1.
Then go 3 units right. That is a run of 3.
gradient = rise/run = 1/3

what is the largest area of a rectangle that can be inscribed in a semicircle of radius 6? round to the nearest whole numb
The largest area of a rectangle that can be inscribed in a semicircle of radius 6 is 36.
What is the semicircle?
A semicircle is a one-dimensional locus of points that makes up one-half of a circle in mathematics. A semicircle's whole arc is always 180 degrees long. It just has one symmetry line.
The equation of the semicircle is
x² + y² = r² .............(1)
The area of the rectangle is
A = 2xy ..................(2)
From equation (1), we get
y² = r² - x²
y = √r² - x²
Plugging this value in equation (2)
A = 2x√r² - x²
Differentiating wrt. x using the product rule,
[tex]\frac{dA}{dx} = 2\sqrt{r^2 - x^2} - 2\frac{x^2}{\sqrt{r^2 - x^2} }[/tex]
[tex]\frac{2r^2 - 4x^2 }{\sqrt{r^2 - x^2} }[/tex]
The critical points are when
[tex]\frac{dA}{dx} = 0[/tex]
that is
[tex]\frac{2r^2 - 4x^2 }{\sqrt{r^2 - x^2} } = 0[/tex]
r² = 2x²
x = r/√2
Then,
y = √r² - x²
= √r² - (r/√2)²
= r/√2
The maximum area is
A = 2 . r/√2 . r/√2 = r²
A = r² = (6)² = 36
Hence, the largest area of a rectangle that can be inscribed in a semicircle of radius 6 is 36.

a farmer plans to enclose a rectangular pasture adjacent to a river. (see figure). the pasture must contain 80,000 square meters in order to provide enough grass for the herd. what dimensions will require the least amount of fencing if no fencing is needed along the river?
Therefore, L has a relative and absolute minimum when x = 400 m
What is Perimeter and Area ?The area is as defined as the amount of space occupied by any shape in two dimensions. Whereas, Perimeter is the boundary or the outline of a flat shape.
Let x = length of the side parallel to the river
y = length of each of the other two sides
Then xy = 80,000, so y = 80,000/x
Minimize: L = length of the fence
L = x + 2y
= x + 160,000/x, where x > 0
L' = 1 - 160,000/x2 = (x2 - 160,000)/x2
L' = 0 when x = 400 or -400
Since x can't be negative, x must be 400.
When 0 < x < 400, L' < 0. So, L is decreasing.
When x > 400, L' > 0. So L is increasing.
Therefore, L has a relative and absolute minimum when x = 400 m
y = 80,000/x = 200 m
The fence is shortest if the side parallel to the river has length 400 m and the other 2 sides each have length 200 m.

a family is traveling due west on a road that passes a famous landmark. at a given time the bearing to the landmark is n 62° w, and after the family travels 9 miles farther the bearing is n 38° w. what is the closest the family will come to the landmark while on the road? (round your answer to two decimal places.) mi
The closest distance the family will come to the landmark while on the road is 12.03 miles.
Here, the situation represented in the question can be depicted as shown in the image below.
The family moves from F1 to F2 as the angle changes from 62 to 38.
Now, using trigonometric ratios in the smaller triangle we have-
Cot 62 = X/Y
X = Y Cot 62
Similarly, Cot 38 = (X + 9)/ Y
Substituting the value of X in the above equation we get-
Y Cot 38 = (Y Cot 62 + 9)
Y Cot 38 - Y Cot 62 = 9
Y(Cot 38 - Cot 62) = 9
Y = 9/ (Cot 38 - Cot 62)
Y = 9/ (1.2799 - 0.5317)
Y = 9/ 0.7482
Y = 12.028

Find the generalized eigenspaces corresponding to the distinct eigenvalues of T.
I believe that once I have the eigenvalues, I know how to find the eigenspaces, but I'm not sure I'm looking for the eigenvalues correctly.
I know that if the eigenvalues are a,b corresponding to (w,0) and (0,z) respectively, then (ab)=1, since a(w)=−z implies ab(−z)=−z. But I think my whole approach to this is wrong and that I'm missing some very elementary idea.
T is the linear transformation described by T(w,z) in L(C2). This indicates that the linear transformation T changes two-dimensional vectors of the type (w,z) to (-z,w).
To get T's eigenvalues, solve the equation T(v) = v, where is the eigenvalue and v is the eigenvector. By solving this equation, we discover that T's eigenvalues are λ1 = -1 and λ2 = 1.
For each eigenvalue, the associated eigenspaces are the subspaces of C2 that are spanned by the eigenvectors of T. The eigenspace is the subspace covered by the eigenvector λ1= -1 is (1,0). The eigenspace is the subspace spanned by the eigenvector λ2= 1 is (0,1).

The sampling distribution is t= 88 degrees of freedom.
To find the sampling distribution of the sample mean difference we need to do a two-sample t-test: equal variances.
When we do a two-sample t-test, we have to take into account the following assumptions:
1) the sample variances are normal.
2) the sample variances of both populations are equal.
Now, let the sample size be [tex]n_x[/tex] and [tex]n_y[/tex] respectively and the means be [tex]x^-[/tex] and [tex]y^-[/tex] respectively.
Now, we are assuming that the distribution of x and y are

[tex]y\sim N[/tex] (mewy, [tex]\sigma y = \sigma[/tex])
Accordingly, the system of hypothesis is defined by:

Therefore, the result of this subtraction of fractions is five eighths.
How to subtract unlike fractions:
Heterogeneous fractions are fractions that have different denominators.
To subtract heterogeneous fractions we follow these steps:
We find the common denominator, which is the least common multiple of the denominators. We divide the common denominator by the other denominator and multiply by the numerator.We will write the above results as numerators with the subtraction sign between them.We subtract the numerators.We simplify the result if possible.The Alpha.Alejandro has a computer support business. He estimates that the cost to run his business can be represented by X = 48 x + 500, where x is the number of customers. He also estimates that his income can be represented by R = 65 x - 145. How many customers he will need in order to break even?
The number of customers Alejandro will need in order to break even is 38 customers.
How to find the number of customers to break even?Given data:
Cost of business = 48 x + 500
Income = R = 65 x - 145
Let x is the number of customers.
Income equation
R= 65x- 145
Substitute 48x + 500 for y
48x + 500 = 65x -145
Substract 48x from both side
500 = 17x - 145
Add 145 to each side
645 = 17x
Divide both side by 17x
x =645 /17
x = 37.9
x = 38 customers (Approximately)
Therefore the number of customers is 38 customers.

if θ measures 0 radians, what is the measure of the angle with an initial ray in the 3 o'clock position and a terminal ray passing through the car?
The measure of the angle with an initial ray in the 3 o'clock position and a terminal ray passing through the car is 0 or origin.
Terminal ray:
In geometry, terminal ray refers the ray in the terminal position, after the rotation, is called the terminal side of the angle.
Given,
Here we need to find if θ measures 0 radians, then the measure of the angle with an initial ray in the 3 o'clock position and a terminal ray passing through the car.
While we looking into the given question,
the value of θ = 0 radians
And the Slope of terminal ray is calculated by using the formula,
=> tan θ
Then Slope = tan 0
Now, by using radians calculator,
=> tan 0 = 0
Therefore, the slope of the terminal ray is 0 which means the origin of the line.
