The entire space or area occupied by an isosceles triangle's sides in a two-dimensional space is known as the triangle's area. Thus the area will be "112.5 cm²".
what is the maximum possible area of an isosceles triangle if the two equal sides are each 15 cm long?
The area is a function of the apex angle β according to
Area = (1/2)(2 cm)²×sin(β)
This will be a maximum for β = 90°. The corresponding length of the third side is 2√2 cm ≈ 2.2828 cm.
The entire space or area occupied by an isosceles triangle's sides in a two-dimensional space is known as the triangle's area. A triangle with two equal sides, which also means two equal angles, is referred to as an isosceles triangle. The following characteristics of an isosceles triangle set it apart from other kinds of triangles: The vertex angle, also known as the apex angle, is the angle formed by the two equal sides of an isosceles triangle. The base is the side that the vertex angle faces, and the base angles are equal.
The vertex angle and the base are both divided in half by the perpendicular from the vertex angle.

The quadratic function h(t)=-16. 1t2+150 models a balls height in feet over time in seconds after it is dropped from a 15 story building
f(x) = ax2 + bx + c, where a, b, and c are real values and a = 0, is a quadratic function. A quadratic function's domain is (,). The graph of the simplest quadratic function, f(x) = x2, is shown below. Its shape, a parabola, should be recognizable from Intermediate Algebra.
To find the time at which the ball hits the ground, we need to find the value of t when h(t) = 0.
Solving -16.1t^2 + 150 = 0 gives us:
-16.1t^2 = -150
t^2 = 9.37
t = 3.05 (rounded to the nearest hundredth)
So the ball hits the ground after 3.05 seconds.

Draw an x-y graph that show the vertical profiles of pressure, density, and temperature in the troposphere. This means the vertical y-axis, which will be height or altitude, going from 0 to 10 km. You can draw three separate graphs, or combine them into one (the axes do not need to be precisely calibrated; you are showing the general trends of each parameter, so the shapes of the plots are important).
The vertical profiles for pressure, density, as well as temperature with in troposphere are displayed in an x-y graph.
Explain the relation of pressure, density, and temperature in the troposphere.Pressure altitude is temperature-adjusted density altitude.
In simple terms, it has a direct impact on an aircraft's performance parameters and is essentially the height at which the aircraft "thinks" it is performing. The performance of an airplane decreases with increasing density altitude and vice versa.Pressure and temperature have a direct and indirect relationship with density.
Density rises as pressure rises and temperature remains constant. Conversely, density falls as temperature rises while maintaining the same pressure. For every 10 hPa decrease in pressure or 3 °C rise in temperature, the air density will drop by around 1%.Thus, the vertical profiles for pressure, density, as well as temperature with in troposphere are displayed in an x-y graph.

The inequality equation is y ≤ -2x + 1 and the graph is plotted
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y ≤ -2x + 1 be equation (1)

Which one of the following is a statistically valid reason for sampling randomly when choosing subjects for a study?Correct Response- Sampling randomly tends to reduce sampling bias or risk- Sampling randomly (with a large sample) gives a perfect reflection of the population- Sampling randomly is easier than sampling nonrandomly- Actually, there is no statistically valid reason for sampling randomly
Sampling randomly is considered a statistically valid reason for choosing subjects for a study as it reduces the risk of sampling bias. The correct option is a.
Sampling bias refers to a systematic error that occurs in the process of selecting subjects for a study, leading to a sample that is not representative of the population.
By selecting subjects randomly, researchers aim to eliminate any preconceived biases or preferences that may influence the selection process. This leads to a sample that is more representative of the population, providing a more accurate representation of the population's characteristics.
Furthermore, random sampling (with a large sample) has the potential to give a perfect reflection of the population, assuming that the sample size is large enough. This is because, as the sample size increases, the sample becomes more representative of the population and tends to exhibit the same characteristics and distributions as the population.

What is Standard Deviation ?
It is a measure of how evenly distributed numbers are. It is the square root of the Variance, which is the average of the squared deviations from the Mean.
To find the sample standard deviation, first, we have to find the mean of the data, then subtract each data point from the mean, square each deviation, sum them, divide by the sample size minus 1, and then take the square root of the result.
Here's the calculation:
Mean = (1 + 5 + 12 + 16 + 15 + 12 + 19 + 5 + 10) / 9 = 11
Deviations = [-10, -6, 1, 5, 4, 1, 8, -6, -1]
Squared deviations = [100, 36, 1, 25, 16, 1, 64, 36, 1]
Sum of Squared deviations = 239
Sample Variance = Sum of Squared deviations / (Sample size - 1) = 239 / (9 - 1) = 239 / 8 = 29.875
[tex]Sample \ Standard\ Deviation=\sqrt{(Sample Variance)} \\\\Sample \ Standard\ Deviation=\sqrt{29.875}\\\\ Sample \ Standard\ Deviation= 5.9[/tex]

the _____ of a square are both congruent and perpendicular.
The diagonals of a square are both congruent and perpendicular.
Because a square is a regular quadrilateral with four equal sides and four equal angles, it is a quadrilateral. A rectangle with two adjacent sides of equal length can also be used to describe it. A chess board, dice, tiles, napkins, etc. are a few examples.
The perpendicular bisectors of a square's diagonals are one another. Each diagonal is divided into two congruent parts as a result, and their intersection creates four right angles. As a result, if a diagonal is given, its length, one segment's length is equal to half of the diagonal's overall length. They are also divided at a 90-degree angle, making them perpendicular, and they are similar in length.

276.46 in^3
Step-by-step explanation:
See the attached worksheet. The pencil balloon if formed by a cylinder and cone. Use the volume formulas for each of these shapes to calculate that shape's contribution to the total volume, and then add them.
The volume of the cylinder portion is 263.9 in^3.
The volume of the cone portion is 12.56 in^3
The sum is 276.46 in^3, which matches the first answer option.
Answer:
276.46 cubic inches
Step-by-step explanation:
Volume of the cylindrical part = πr²h, r= radius, h = height
Volume of a cone (1/3) πr²h, r= radius, h = height
For given dimensions
cylinder h = 21, cylinder r = 2
Volume of cylindrical part of balloon = π · 2² · 21 = 4 · 21 · π = 84π cubic inches
Volume of conical part of balloon = (1/3) π · 2² · 3 = 4π
Total volume = 84π + 4π = 88π = 276.46 cubic inches

2x＝ 3 -5√x using log form, x = log(2x + 5√x) = log(3)
How did we get the value?To convert the equation 2x = 3 - 5√x into logarithmic form, we need to isolate the radical expression on one side of the equation. We can do this by adding 5√x to both sides:
2x + 5√x = 3
Next, we'll take the square root of both sides to eliminate the radical:
√(2x + 5√x)^2 = √(3^2)
Expanding the left side and simplifying:
2x + 5√x = 3
Finally, we'll take the logarithm of both sides to get x in logarithmic form:

The equation in x and y whose graph is the path of the particle is y = (x - 4)2 + 5. The velocity vector at t= 4 is v(4) = i + 8j.
What is vector?A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.
In mathematics, a vector's magnitude is defined as the length of a segment of a directed line, and the vector's direction is indicated by the angle at which the vector is inclined.
Given r(t) as r(t) = x(t)i + y(t)j
Thus, this means that:
x = t+ 4 y = t2 + 5
We see that we can solve t as:
t = x - 4, thus:
y = (x - 4)2 + 5
v(t) is given by r'(t).
r'(t) = v(t) = i + 2tj
