each side of a square is increasing at a rate of 2 cm/s. at what rate is the area of the square increasing when the area of the square is 81 cm2?
The area of the square is increasing at a rate of 36 cm/s2.
What is the rate of expansion of a solid?
For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for the thermal expansion of solids in daily life.
A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.
Calculation
L = length of a side
A = L2
dA/dt = 2L dL/dt
dL/dt = 2 cm/s
A = 81 sqcm ⇒ L = √A = √81 cm = 9 cm
dA/dt = 2(9cm)(2 cm/s) = 36 sqcm
Hence the rate is the area of the square increasing is 36sqcm

Using the rate of change of area ,
If the area of a square is 81 cm² the area of the square increases at a rate of 36 cm²/s.
Suppose that initially there were no squares, but suddenly squares began to form at a constant rate. At the end of the first second, the sides were 2 cm long each, and at the end of the second second they were 4 cm each. Therefore, we can say that the rate of change of increasing sides is 2 cm/s. If a square has a side of S cm, this is expressed mathematically.
dS/dt = 2 cm/s ---(1)
Since we know the area of the square is given by
A=S² cm²
the derivative of the area function shows the variation of area with respect to side S
dA/dS=2S
So , when area of square is 81 cm² , its side length is 9 cm. Since we need rate of change of area w.r.t. time, we need to multiply both the sides by dS/dt .
dA/dS×dS/dt=2S×dS/dt
=> dA/dt=2S×dS/dt
=> dA/dt = 2×9 ×2 = 36 cm²/s
Hence, the required area increasing rate is 36 cm²/s.

The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers
If the perimeter is 92 feet, find the value of the longest of the four side lengths.
The value of the longest of the four side lengths is 26 feet.
How to calculate the value?Let the integers be x, x + 2, x + 4 and x + 6.
Since the perimeter is given as 92 feet. This will be:
x + x + 2 + x + 4 + x + 6 = 92
4x + 12 = 92
Collect like terms
4x = 92 - 12
4x = 80
Divide
x = 80 / 4
x = 20
The longest side will be:

How do I make sure a parabola(quadratic function) equation goes through specific points using standard form? An example is an equation that goes through the points (-4,0), (3,0) and (2,-18).
NO TROLLS, PLEASE!
An equation that goes through the given points is [tex]y=3x^{2} +3x-36.[/tex]
What is the parabola equation?
A parabola is a graph of a quadratic function. An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively.
Given points are (-4,0), (3,0), and (2,-18).
The equation of a parabola is [tex]y = \frac{1}{4 \left(f - k\right)} \left(x - h\right)^{2}[/tex]
Since the point (−4,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(-4 - h\right)^{2} + k[/tex]
Since point (3,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(3 - h\right)^{2} + k[/tex]
Since point (2,−18) lies on the parabola, then [tex]-18 = \frac{1}{4 \left(f - k\right)} \left(2 - h\right)^{2} + k[/tex]
Solving the above all three systems, we get that [tex]h= -\frac{1}{2} , k = - \frac{147}{4}, f = -\frac{110}{3}[/tex]
Substituting the above value in the equation of a parabola, we get

Answer:
[tex]x=-2\frac{9}{23} , y=\frac{16}{23 }[/tex]
Step-by-step explanation:
7x - 9y = -30 ------ equation (1)
-3x - 6y = 3 ------ equation (2)
From equation (2),
3x + 6y = -3
x + 2y = -1
∴ x = -2y - 1 ------ equation (3)
Substitute equation (3) into equation (1):
7(-2y - 1) - 9y = -30
-14y - 14 - 9y = -30
-23y = -16
23y = 16
∴ y = [tex]\frac{16}{23}[/tex]
Substitute y = [tex]\frac{16}{23}[/tex] into equation (3):
x = -2([tex]\frac{16}{23}[/tex]) - 1

Answer:

Step-by-step explanation:
You want the distance between P(8, 2) and Q(3, 8).
Distance between pointsThe distance between points is given by the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((3 -8)² +(8 -2)²) = √((-5)² +6²) = √61
d ≈ 7.8
The distance between points P and Q is about 7.8 units.

Additional comment
You will notice that the desired distance is the length of the hypotenuse of a right triangle with legs that are 5 and 6. The Pythagorean theorem tells you that length is √(5² +6²) = √61, as above. The distance formula is based on the Pythagorean theorem.
You can find the relevant triangle leg lengths by counting grid squares on the graph. Of course, the distance formula does the same thing by subtracting coordinate values.
