Every single one of those expressions factor.  When factored, this is what we have: \frac{(3x-7)(x+3)}{(x+3)(x-2)} * \frac{(2x-7)(x+9)}{(3x-7)(2x+7)}.  After canceling out like factors, what we are left with is this: \frac{1x+9}{1x-2}.  That means that b = 9, c = 1, and d = -2

Examine the diagram and information to answer the question.
Morgarella [4.7K]

Answer:

23.4 units

Step-by-step explanation:

Given the point of the vertices of triangle ABC as A(−5,1), B(2,1), and C(6,4).

The distance (d) between two points X (x₁ , y₁) and Y(x₂, y₂) is given as:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}. We can use this to calculate the length of the sides of the triangle. Therefore:

AB=\sqrt{(2-(-5))^2+(1-1)^2}=\sqrt{7^2}=7\\  AC=\sqrt{(6-(-5))^2+(4-1)^2}=\sqrt{11^2+3^2}=11.4\\\\BC=\sqrt{(6-(2))^2+(4-1)^2}=\sqrt{4^2+3^2}=5\\

The perimeter of the triangle ABC = AB + AC + BC = 7 + 11.4 + 5 = 23.4 units

A population P is initially 3000. Find an exponential model (growth or decay) for the population after t years if the population
sergey [27]

The population model is an exponential decay because it decreases

The exponential model of the population is P = 3000(0.64^1/7)^t

<h3>How to determine the function?</h3>

The population decreases by 0.36 every 7 years.

This means that the function is an exponential decay.

An exponential decay function is represented as:

P = a((1 - r)^1/n)^t

Where:

  • a represents the initial value (3000)
  • r represents the rate (0.36)
  • n represents the number of years the population decreases (7)
  • P and t are the variables

So, we have:

P = 3000((1 - 0.36)^1/7)^t

Evaluate the difference

P = 3000(0.64^1/7)^t

Hence, the exponential model of the population is P = 3000(0.64^1/7)^t
