If sides of a triangle are a = 3, b = 6, and c = 7, then what is the altitude of the triangle?
The triangle is 2.98142 meters high.
Explain about the altitude of the triangle?The height of a triangle is the perpendicular tracing from one side to the other of the triangle. The height of the triangle is also referred to as the altitude, which joins the base to form a right-angle triangle.
The formula h = xy, where x and y are the bases of the two analogous triangles formed when the height of the right triangle is drawn from one vertex to its hypotenuse, can be used to determine the altitude of a right triangle.
A line segment connecting a triangle's vertex to its opposite side is known as the triangle's altitude. In relation to the base or the side it touches, it is perpendicular. It is possible to draw three altitudes in a triangle because it has three sides. The Orthocenter is the location where the three heights of a triangle intersect.

Graph the line using slope and y intercept y=-1/3x - 7
Answer:
To graph the line using slope and y-intercept, we can follow these steps:
Identify the slope and y-intercept:
The slope of the line is -1/3.
The y-intercept is -7.
Plot the y-intercept:
Plot the point (0, -7) on the coordinate plane, since this is the point where the line intersects the y-axis.
Plot additional points using the slope:
Choose a convenient value for x (such as x = 1) and use the equation of the line to find the corresponding value of y.
Plot this point on the coordinate plane.
Repeat the process for several more values of x to obtain additional points on the line.
Connect the dots:
Draw a line through the points that you have plotted, connecting them to form the graph of the line.
Note: The line y = -1/3x - 7 will have a negative slope and will decrease as x increases, which means that the line will slope downward from left to right.
Let a = (0, 0), b = (7, 2), c = (3, 4), d = (3, 7), and e = (−1, 5). Cameron walks the polygonal path abcdea, writing down the number of degrees turned at each corner. What is the sum of these five numbers? notice that abcde is not a convex pentagon
Sum of angles at 5 corners of a polygonal path abcdea is 360 degrees (assuming convex polygon).
What is vector ?
Vector is a term that refers colloquially to some quantities that cannot be expressed by a single number, or to elements of some vector spaces.
The sum of the angles at the corners of a polygon is equal to (n-2) times 180 degrees, where n is the number of sides of the polygon. In this case, n = 5, so the sum of the angles at the corners is (5-2) * 180 = 360 degrees.
However, this assumes that the polygon is convex. Since abcde is not a convex pentagon, need to calculate the angles at each corner separately.
The angle between two lines can be calculated using the dot product formula:
cos(θ) = (u⋅v) / (||u|| * ||v||)
where u and v are the vectors representing the lines, and ||u|| and ||v|| are their magnitudes. The angle θ is between 0 and 180 degrees.
For example, to find the angle between the lines ab and bc,use the vectors b-a and c-b:
cos(θ) = (b-a⋅c-b) / (||b-a|| * ||c-b||)

The sum of these five numbers is 66.59 degrees.
To find the sum of the angles turned at each corner, we need to find the angle between each pair of adjacent sides.
First, we find the slope of the line segment between each pair of points:
AB: slope = (2-0)/(7-0) = 2
BC: slope = (4-2)/(3-7) = -2
CD: slope = (7-4)/(3-3) = 3
DE: slope = (5-(-1))/(-1-3) = -6
EA: slope = (0-5)/(0-(-1)) = 5
Next, we find the angle between each line segment using the inverse tangent function (atan).
AB: angle = atan(2) = 63.43 degrees
BC: angle = atan(-2) = -63.43 degrees
CD: angle = atan(3) = 71.57 degrees
DE: angle = atan(-6) = -84.97 degrees
EA: angle = atan(5) = 79.56 degrees
Adding up all the angles, we get:
63.43 + (-63.43) + 71.57 + (-84.97) + 79.56 = 66.59 degrees
So the sum of the five angles is 66.59 degrees.

The volume of the solid can be found by using the general slicing method which involves slicing the solid into multiple thin slices, computing the volume of each slice.
The general slicing method can be used to find the volume of the solid with a semicircular base of radius 9 whose cross section is a triangle. This method involves slicing the solid into multiple thin slices, computing the volume of each slice, and then summing up the volumes of all the slices. To find the volume of each slice, we first need to determine the area of the cross-section for each slice. The area of the cross-section can be found by multiplying the base of the triangle by its height. For each slice, the base of the triangle is equal to 2πr/N, where r is the radius of the semicircle and N is the number of slices. The height of the triangle is equal to the thickness of each slice. Once the area of the cross-section is calculated, we can find the volume of each slice by multiplying the area by the thickness of the slice. Finally, the volume of the solid is equal to the sum of the volumes of all the slices.

What is the least number of items Team A needs to sell to avoid losing money?
Team A needs to sell 255 bags of popcorn to reach their goal of $100.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Team A will sell the bags of popcorn for $0.50 each.
Team B will sell the cotton candy for $0.75 per stick.
Let the number of bags of popcorn sold by Team A be "x".
So, the total cost for the popcorn machine rental and supplies is
= $15 + 0.05x.
To reach their goal of $100
$100 = 0.5x - ($15 + 0.05x)
$100 = 0.5x - $15 - 0.05x
$115 = 0.45x
x = $115 / 0.45
x = 255 bags of popcorn

if a =determine the values ofx and y for which a^2 = a
Answer: - 14.4
Step-by-step explanation:
Matrices are used to represent data in rows and columns. The values of x and y are 9 and -14.4 respectively.
Matrix A is represented as: ( x -5, y -8)
Calculate A2: A2: (x 5, y -8) x (x 5, y -8)
Recall that A2 = A
This means that: (x2 + 5y, 5x - 40) = (x 5)
( xy - 8y, 5y + 64) = (y -8)
So, by comparison:
5x - 40 = 5
5x = 40 + 5
5x = 45
x = 9
Similarly:
5y + 64 = -8
5y = -64 - 8
5y = -72
y = -14.4
Hence, the values of x and y are 9 and -14.4 respectively.
The equation a² = a is true, when the value of "x = 1" and "y = 1".
An equation is a mathematical statement that asserts that two expressions are equal.
When we are given an equation like
=> a² = a
it means that the value of a² on the left side is equal to the value of "a" on the right side.
Here we need to find the values of "x" and "y" for which this equation is true.
Let's start by assuming that the value of "a = 1".
In that case, the equation
=> a² = a
=> 1² = 1.
And since 1 raised to the power of 2 is equal to 1, this equation is true. Therefore, we have found a solution for the equation: "a = 1".

where p, q and r are the sides of triangle and R is the angle between sides q and p.
therefore, [tex]28^{2} = 17^{2} +15^{2}[/tex] - 2(28)(17)cos R
cos R = -270/952
= -0.284
R = cos-1(-0.284)
therefore, R = 106.499 = 106.5 approximately.

Answer:
I can't understand your question do comment the question.what is 2 x 4 + 82 - 18 divide by 8 x 9?
Answer:
1 because,
(2*4+82-18)/8*9
(8+82-18)/72
(90-18)/72
72/72
1
Answer:
Step-by-step explanation:
2 x 4 + 82 - 18 / 8 x 9
We want to use the PEMDAS rule for working math problems with more than one operation.
P = Parentheses first
E = Exponents second
M/D = Multiplication and division third
A/S= Addition and subtraction last
There are no parentheses, so we look for exponents next and there are none.
The next operations are multiplication and division.
Step 1
2 x 4 = 8
8 + 82 - 18 / 8 x 9
Step 2
8 x 9 = 72
Step 3
8 + 82 - 18 / 72
Before we can divide by 72, we need to add and subtract the top numbers from left to right.
Step 4
8 + 82 - 18 = 72
72/72
Now divide 72 by 72
Step 5
72/72 = 1
Suppose that a and b are nonzero vectors.
(a) Under what circumstances is compa b = compb a?
(b) Under what circumstances is proja b = projb a?
a) Compa a = compa b is occurs when the two vectors are proportional
b) Proja b = proja a is occurs when the two vectors are parallel.
A vector is a mathematical object with both magnitude and direction.
In the context of vectors, "comp" refers to the scalar (or dot) product and "proj" refers to the projection. The scalar product of two vectors is a scalar that measures the degree to which two vectors are pointing in the same direction. The projection of a vector is a vector that represents the component of the vector in a specific direction.
(a) The scalar product of two vectors is equal if and only if the two vectors are proportional. In other words, if a and b are nonzero vectors such that compa b = compb a, then the two vectors must be pointing in exactly the same direction.
(b) The projection of a vector is equal if and only if the two vectors are parallel. In other words, if a and b are nonzero vectors such that proja b = projb a, then the two vectors must be parallel, or pointing in exactly the same direction.
