determine the base, b, of the exponential model. Is the base a growth or decay factor? a. b is 0.6394; It is a growth factor. b.
Kazeer [188]
An exponential model can be described by the function
f(x) = a(b)^x
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.

When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.

Given the exponential model
n=20.5(0.6394)^t
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.

Here, the base is 0.6394 which is less than 1, hence a decay factor.

Therefore, <span>the base, b, of the exponential model is 0.6394; It is a decay factor.</span>

What is the step by step and on this expression 4b+9+b
AleksAgata [21]

Answer:

5b + 9

Step-by-step explanation:

You are essentially trying to simplify the expression given to you. To do so, combine terms with like terms:

4b + 9 + b

In this case, combine all terms with the same amount of variables, b.

(4b + b) + 9 = 5b + 9

5b + 9 is your answer.

Jamal will slice a right circular cylinder into two congruent pieces. Which two dimensional plane sections could result from the
GarryVolchara [31]

Answer:

An ellipse and a rectangle.

Step-by-step explanation:

If Jamal cuts the right circular cylinder anywhere but its extremities, the resulting shapes on both pieces will be an ellipse.  

If he cuts precisely in a perpendicular way in relation to the ends, he will then form two new right circular cylinders, then the ellipses obtained would be circles.

If Jamal cuts the right circular cylinder lengthwise, going from one end to the other, even if it's not perpendicular to the base, he will obtain a rectangular shape.

Find the solutions of the quadratic equation by finding the square root: x2 - 3 = 7.
Masja [62]

Answer:

<em>x = - √10, and x =√10</em>

Step-by-step explanation:

1. Let us add 3 to either side of the equation: x^2 - 3 + 3 = 7 + 3

2. That equation would simplify to: x^2 = 10

3. Now let us take the square root on either side: √x^2 = √10

4. Being square root of x^2, we could say that: | x | = √10

5. And thus 2 answer may be derived from this equation provided absolute value symbol ( | | ): <em>x = - √10, and x =√10</em>
