The appropriate thing to do is what you would do with any math.
• Study the reference material and examples you are given, making sure you understand where the formulas apply and how they are used.
• Memorize the formulas you cannot derive easily based on the understanding you have.
• Work homework and extra problems until you can apply the formulas quickly and easily to any problem to which they are relevant.

_____
The distance formula is based on the Pythagorean theorem. For a right triangle of side lengths a and b and hypotenuse c, the Pythagorean theorem tells you
  c² = a² + b²
Taking square roots, you get
  c = √(a² + b²)

When "a" and "b" are the differences of coordinates in the Cartesian plane, this becomes the distance formula:
  d = √((x₂-x₁)² + (y₂-y₁)²)



You can arrive at the midpoint formula a number of ways. I find it convenient to remember that the coordinates of a midpoint are simply the average of the coordinates of the end points. That is,
  for midpoint M = (mx, my), and endpoints A = (ax, ay), and B = (bx, by)
  M = (A+B)/2
  (mx, my) = ((ax +bx)/2, (ay +by)/2)

Write a differential equation that models the given situation. The stated rate of change is with respect to time t. (Use k for t
Alex787 [66]

The differential equation that models the given situation will be dy/dt = K(N - y).

<h3>How to compute the equation?</h3>

Let y = number of individuals who have heard about the product.

Let N - y = this who haven't heard about the product.

From the given statement, the rate for change will be t = dy/dt. Therefore, the differential equation that models the given situation will be dy/dt = K(N - y).

Square ABCD is located on a coordinate plane. The coordinates for three of the vertices are listed below.
Marrrta [24]

Answer:

B'(16,14)

Step-by-step explanation:

First find the coordinates of the vertex B. The center of the square M is the midpoint of the diagonal AC. Since A(2,7) and C(8,1), the center has coordinates

M\left(\dfrac{2+8}{2},\dfrac{7+1}{2}\right)=M(5,4).

Point M is also the midpoint of the diagonal BD. Let B has coordinates (x,y), then

\dfrac{x+2}{2}=5\Rightarrow x=8,\\ \\\dfrac{y+1}{2}=4\Rightarrow y=7.

Hence, B(8,7).

Now, the dilation by a scale factor 2 with the center of dilation at the origin has the rule

(x,y)→(2x,2y).

Thus,

B(8,7)→B'(16,14).
