An isosceles triangle is just what?As an outcome, an isosceles triangle has two equal sides as well as two equal angles. As from Greek words iso (same) and skelos, the phrase is formed (leg). Except for a right triangle, which has quadrilateral on all sides, a scalene triangle lacks equal sides on each side.
The slope of the line connecting the bottom right vertex of something like the triangle to the top left vertex of both the square is equal to -1/2.
This line's equation is y = (-1/2)x + 10. (1)
The point at the triangle's top vertex is (15, 10)
The slope of the segment between (10, 0) and (15, 10) is 10/5, which equals two.
The line connecting these two locations has the equation y = 2(x - 10) y = 2x - 20. (2)
You may get the x coordinate of the point where these lines cross by putting (1) = (2)
(-1/2)x + 10 = 2x - 20
30 = [5/2]. x x equals 12 and y equals 2(12) - 20 = 4.
Therefore, the triangle's shaded area's height is 4 and its base is 10.
Its area is therefore (1/2)(4)(10) = 20 units squared.

Step-by-step explanation:
I choose a random integer n between 1 and 10 inclusive. What is the probability that for the n I chose, there exist no real solutions to the equation x(x+5)=−n? Express your answer as a common fractio
The probability is 1/10.
The equation x(x+5) = -n can be rewritten as x^2 + 5x + n = 0. To find the solutions of this equation, we can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a, where a = 1, b = 5, and c = n.
For there to be no real solutions, the discriminant (b^2 - 4ac) must be negative. The discriminant is 5^2 - 4(1)(n) = 25 - 4n. So for there to be no real solutions, 25 - 4n < 0, or n > 6.25.
Since the integer n is between 1 and 10 inclusive, the only value that would not have a real solution is n = 7. Therefore, the probability that for the randomly chosen n there exist no real solutions is 1/10.

a rectangle has its upper two vertices on the graph of and its lower two vertices on the -axis. what is the maximum possible area of the rectangle?
The maximum area of the rectangle is determined by the distance between the two points on the graph and the -axis.
What is rectangle?A rectangle is a four-sided shape with four right angles and two pairs of parallel sides. It is one of the most common shapes in the world, found in everything from building designs to artwork. Rectangles are also used in math, specifically to measure area and perimeter. Rectangles can also be classified according to their sides, with squares being a special type of rectangle with four equal sides.
To calculate the maximum possible area of the rectangle, we can use the formula A = (x2 - x1)(y2 - y1).
In this case, the two points on the graph have the same -coordinate, so the x2 - x1 part of the equation is zero. This means that the y2 - y1 part of the equation gives the maximum possible area of the rectangle. To calculate this, we need to take the difference between the two points on the graph.
For example, if the two points on the graph were (2,4) and (2,6), the maximum area of the rectangle would be (6 - 4) = 2.
Therefore, the maximum possible area of the rectangle is equal to the difference between the two points on the graph.

Calculus's core tool is the derivative. The velocity of an item, for instance, is the derivative of its position with respect to time; it quantifies how quickly the object's position varies as time passes.
When it occurs, the slope of the tangent line to the function's graph at a given input value is the derivative of a function of a single variable. The function closest to that input value is best approximated linearly by the tangent line.

a library is having a book sale to raise money hardcover book scost $4 each and paperback books cost $2 each. a person spends $26 for 8 books. how many of each type of book did she buy
Answer: 5 hardcover and 3 paperback
Step-by-step explanation: To solve, we need to keep this question in mind:
"How many books can we buy for each without going over the initiate amount [$26]?"
So, let's start with the $4 books, so knowing our multiples of 4
ex. 4, 8, 12, 16, 20, 24, 28......
So, I listed the example of the multiples. So, it can be either 20 or 24. So, it would be 20, because it is under the initiate amount AND it is less with unincluded paperback books. So, 26-20 = 6. So, if each paperback book costs $2, we need to divide 6 by 2. That's 3. So, therefore, she can buy 5 hardcovers and 3 paperbacks by spending all the money. I hope this helps!

The different percentages of the distance is 100%, 25% & 125%.
How to find the table to show different percentage of the distance?The Latin word "per centum," which means "by the hundred," served as the basis for the English word "percentage." Percentages are fractions with the denominator 100. In other words, it is the relationship between a part and a whole in which the value of the whole is always assumed to be 100.
A percentage is a fraction or ratio in which the whole value is always 100. For instance, Sam would have received 30 out of a possible 100 points if he had received 30% on his math test. It is expressed as 30/100 in fractional form and 30:100 in ratio form.

A quare piece of cloth i ize 25 m quare i cut into rectangle trip of 50 50 cm wide find the number of tate and their total length in metre
All of the rectangles together measure 1250 meters in length.
A textile square with a 25 square meter surface area. We are aware that the area of a square is determined by multiplying one side's length by itself. The square root of 25 square meters, or 5 meters, is the length of one side of the square in this instance.
Secondly, we are aware that the fabric is being cut into 50 cm-wide rectangles. We can use the following formula to determine each rectangle's length:
(Rectangle width) x (Square cloth length) / (Width of square cloth)
The equation in this instance is (50 cm) x (25 m) / (5 m) = 2500 cm or 25 meters.
Therefore, each rectangle is 25 meters long.
We divide the square cloth's length by each rectangle's width to get the total number of rectangles.
25m / 0.5m (50cm) = 50 rectangles.
Finally, we multiply the quantity of rectangles by the average length of each rectangle to determine the total length of all the rectangles:
50 m x 25 m = 1250 m
Therefore, a square piece of fabric that is 25 square meters in size and has been divided into 50 rectangles, each measuring 50 cm wide and 25 meters long.
Therefore the rectangles together measure 1250 meters in length.

A(−2,3),B(4,3),C(4,−1)
The fourth co-ordinate of the rectangle is D (-2, -1). The equation of the line that passes through the points B and D is 3y = 2x + 3.
The given points are:
A(−2,3), B(4,3), C(4,−1)
When we plot these points on the graph we can easily estimate the fourth point which will be equidistant from A as the point C is from B and from the point C as the point A is from B.
Therefore, the diagonal points are B(4, 3) and D(-2, -1).
The equation of the line between these two points is:
(y - y1) = ((y2 - y1)/(x2 - x1)) (x - x1)
(y - 3) = ((-1 -3)/(-2 - 4)) ( x - 4)
y - 3 = (2/3) (x - 4)
3y - 9 = 2x - 8
3y = 2x + 1

There are two separate random samples available.
what is random sample?selected at random (purely random, unpredictable). Every member of the population being polled ought to have an equal probability of getting chosen. She randomly selected 25 names from a pool of 250 employees as an example of a simple random sample. Since there are 250 of her employees in total, and each one has an equal probability of being chosen, the sample in this instance is random. Using simple random sampling, which is a form of probability sampling, researchers choose individuals at random from a population. There is an equal opportunity for selection for every person in the population.
