Using mathematical operations, the population of Alaska in 2050 will be 8,99,500.
<h3>
What are mathematical operations?</h3>
- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- A mathematical action is called an operation. Mathematical operations include addition, subtraction, multiplication, division, and finding the root.
So, the population in 2050:
- Population increases from 2000 to 2020:
- 733,000 - 622,000 = 1,11,000
- Population change in 20 years = 1,11,000
- In 10 years = 1,11,000/2 = 55,500
So, poulation in 5050:
- 2020 (20 years) ⇒ 2040 (00 years) ⇒2050
- = 733,000 + 1,11,000 + 55,500
- = 8,99,500
Therefore, using mathematical operations, the population of Alaska in 2050 will be 8,99,500.

After plotting all the three points, we get the parabolic equation in the form is 2(x - 1)²-34.
<h3>What is parabola?</h3>
Any point on a parabola, which has the shape of a U, is situated at an equal distance from the focus, a fixed point, and the directrix, a fixed line.
General equation of the quadratic equation,
Y = ax² + bx +c
Given points,
(-2, 0),
(-1, -10),
(4, 0).
Putting the points in the general equation,
Putting (-2, 0), we get
0 = 4a - 2b + c
Putting (-1, -10), we get
-10 = a - b +c
Putting (4, 0), we get
0 = 16a + 4b +c
Solving all equations we get,
a = 2 , b = -4 , c = -16
After putting the values,
Y = 2x²- 4x- 16
2(x² - 2x - 8)
2(x²- 2x + 1 - 1 - 16)
=2(x - 1)²-34
Hence we get the required equation in the parabolic form.

Answer:
.625 for decimal, and 62.5 percent.
Step-by-step explanation:
1/8 is 1.25 and that times 5 is .625. .625 * 100 = 62.5

Idk if you should repost this with a better pic though
Answer:
2)
collect like terms
move the constant to the right hand side and change its sign.
Subtract the numbers
Divide both sides of the equation by 8
