PEMDAS is very helpful and is a required to obtain answers to special equations
For example: (6-2) •2
You would do what’s in the brackets first. :
6-2= 4
4•2 = 8
Answer: 8

PEMDAS is very helpful. Without pemdas, people solve equations differently. For example, 2 + 3 * 2. Using pemdas, we knoow 2 + 3 * 2 = 8

However, without pemdas, someone could do 2 + 3, which is 5, then *2. Which would get 10.

PEMDAS is important to keep order.

A school plays a series of 6 soccer matches. For each match there are 3 possibilities: a win, a draw or a loss. How

Sphinxa [80]

Answer:

There are 729 possible results are there for the series

Step-by-step explanation:

If we have n trials, each with m possible outcomes, the total number of possible outcomes is:

$T = m^{n}$

In this question:

6 games(trials), so $n = 6$ .

Each with three possible outcomes, so $m = 3$

Then:

$T = 3^{6} = 729$

There are 729 possible results are there for the series

Is this correct??????

-BARSIC- [3]

Answer: a) x ≈ 7.39

<u>Step-by-step explanation:</u>

$6+ln\ x=8\\\\\\\text{Subtract 6 from both sides:}\\ln\ x=2\\\\\\\text{Apply e to both sides:}\\e^{ln\ x}=e^2\\\\\\\text{Cancel out }e^{ln}:\\x=e^2\\\\\\\text{Use a calculator to find the value of }e^2:\\x\approx7.389\\\\\\\text{Rounded to the nearest hundredth:}\\\large\boxed{x\approx 7.39}$

<h3>Answer: Choice D) </h3>

Domain: all real numbers
Range: y > -100 (not $y \ge -100$ )
Type of function: exponential

=================================================

Explanation:

The graph goes on forever to the left and right. This means any real number x can be plugged into the function to get some output y. The domain is the set of all real numbers. In interval notation, we would say $(-\infty, \infty)$ which is another way of saying $-\infty < x < \infty$

The range is y > -100 because the exponential graph steadily approaches this horizontal asymptote. Think of it like an electric fence you cannot touch. Since we never actually get to this y value, this means y = -100 is not part of the range. Your teacher made a typo when they wrote $y \ge -100$ and instead they should have written $y > -100$ . So basically y can be anything larger than -100. The graph may look like it eventually reaches y = -100 itself, but it's actually just getting closer and closer to this y value. To write the range in interval notation, we would say $(-100, \infty)$

This function is exponential because it has the general shape all exponential growth functions do. We have a fairly flat part with very slow growth at first, but then as time goes on, the growth rate increases dramatically resulting in the very steep curve.

Quartic polynomials are 4th degree polynomials. They have the same end behavior as quadratic functions do, since both are even degree polynomials. We don't have a quartic here because the left end behavior isn't going off to positive infinity as the right end behavior is.
