None of those could be a radical, you would have to have a radical symbol for it to become a radical

Answer:

  • D. 24736 people and 29 years

Step-by-step explanation:

<u>The model given is:</u>

  • P = 16581*e^(0.02t)

<u>Population in 2020, t = 20</u>

  • P = 16581*e^(0.02*20) = 24736 people (rounded)

<u>Population of 30000:</u>

  • 30000 = 16581*e^(0.02t)
  • e^(0.02t) = 30000/16581
  • e^(0.02t) = 1.80929
  • ln e^(0.02t) = ln 1.80929
  • 0.02t = 0.5929
  • t = 0.5929/0.02
  • t = 29.645 ≈ 29 years

Correct choice is D

bazaltina [42]

Answer:

Reflection about the vertical line x = 2.5 inches will map the square unto itself

Step-by-step explanation:

The given parameters are;

The area of the square = 25 in²

The orientation of the sides of the square are horizontal and vertical

Therefore, we have;

The area, A, of the square given by the following relation;

A = Side²

A = 25 in²

Therefore;

The area of the square = 25 = side²

The length of the sides of the square = √A = √25 = 5

The length of the sides of the square = 5 inches

The reflection of a figure that maps the figure unto itself is a reflection along the line of symmetry

One of the line of symmetry that divides the square into two similar halves is the vertical straight that passes half way through the horizontal side, which is the point 2.5 inches to the right on the x-axis with the coordinates (2.5, 0)

Therefore, reflection about the line x = 2.5 inches will map the square unto itself.

A married couple together earns 110,000 a year. The wife earns 16,000 less than twice what her husband earns.what does the husba
Alex17521 [72]
If we place what the husband earns as h and what the wife earns as w, we can begin...
w + h = 110000

but w = 2h - 16000

We can turn it into..

2h - 16000 + h = 110000

Which we can then combine into..

3h - 16000 = 110000

Add 16000 and..

3h = 126000

Divide by three...

h = 42000

(nice)

The husband earns 42,000$ a year

Bonus: The wife then earns 68,000$

42,000 (or h) + 68,000 (or w) = 110,000

Because this is the original equation, we are correct.
