Final answer:

The electron configuration for each ion can be determined using the noble gas core notation.

Explanation:

The electron configuration for each of the given ions can be determined using the noble gas core notation. The noble gas notation involves representing the core electron configuration with the symbol of the noble gas that matches it, followed by the electron configuration of the valence electrons. For example, the electron configuration of a sodium ion ([Na]⁺) using the noble gascore notation is [Ne]3s².

Answer: B) 6 minutes

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

Explanation:

Let's find the slope of the table. This will tell us the rate of change.

m = slope

m = (y2-y1)/(x2-x1)

m = (25250 - 26375)/(2 - 1) .... I used the first two rows

m = -1125/1

m = -1125

The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.

Since we're told the initial altitude was 27500 ft, this means b = 27500

This means y = mx+b turns into y = -1125x+27500

x is the number of minutes and y is the altitude at time x

As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.

------------------

Now plug in y = 16250 and solve for x

y = -1125x+27500

16250 = -1125x+27500

-1125x+27500 = 16250

-1125x = 16250-27500

-1125x = -11250

x = -11250/(-1125)

x = 10

It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.

Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.

What is the degree of a polynomial function?

In Mathematics and Geometry, the degree of a polynomial function is sometimes referred to as an absolute degree and it's the greatest exponent (leading coefficient) of each of its term.

Based on the information provided, we have the following polynomial function:

h(x) = x³ + 2x² – 11x – 12

Since the leading coefficient of the above polynomial function is positive, and the degree is odd, the end behavior can be described as follows;

As x tends towards negative infinity, h(x) tends towards negative infinity i.e x → -∞, h(x) → -∞.

As x tends towards positive infinity, h(x) tends towards positive infinity i.e x → ∞, h(x) → ∞.

If you know the area of a rectangle can you predict its perimeter? Explain

Answers

No. The area doesn't tell you the dimensions, and you need
the dimensions if you want the perimeter.

If you know the area, you only know the product of the length and width,
but you don't know what either of them is.

In fact, you can draw an infinite number of different rectangles
that all have the same area but different perimeters.

Here. Look at this.
I tell you that a rectangle's area is 256. What is its perimeter ?

-- If the rectangle is 16 by 16, then its perimeter is 64 .
-- If the rectangle is 8 by 32, then its perimeter is 80 .
-- If the rectangle is 4 by 64, then its perimeter is 136 .
-- If the rectangle is 2 by 128, then its perimeter is 260 .
-- If the rectangle is 1 by 256, then its perimeter is 514 .
-- If the rectangle is 0.01 by 25,600 then its perimeter is 51,200.02

Because of the correlation of its width and length. In a rectangle length are equal, the same for the width.
