Answer:

In year 2030 the population is predicted to be 71.75 million

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- Using data from 2010 and projected to 2020, the population of

 the United Kingdom (y, in millions) can be approximated by the

 equation  10.0 y − 4.55 x = 581

- x is the number of years after 2000

- We need to know in what year the population is predicted to be

  71.75 million

* <em>Lets substitute the value of y in the equation by 71,75</em>

∵ The equation of the population is 10.0 y - 4.55 x = 581

∵ y = 71.75

∴ 10.0(71.75) - 4.55 x = 581

∴ 717.5 - 4.55 x = 581

- Subtract 717.5 from both sides

∴ - 4.55 x = - 136.5

- Divide both sides by - 4.55

∴ x = 30

∵ x represents the number of years after 2000

∵ 2000 + 30 = 2030

∴ In year 2030 the population is predicted to be 71.75 million

It is estimated that the average amount owed for student loans in 2010 was $25,250 per student.  If the interest rate for studen
Nostrana [21]
Given:
loan amount: 25,250
original interest rate: 3.4%
new interest rate: 6.8%
term: 10 years.

Assuming that simple interest formula is used.
I = P * r * t
I = interest
P = principal
r = interest rate
t = term/time

I = 25,250 * 3.4% * 10 years
I = 8,585

I = 25,250 * 6.8% * 10 years
I = 17,170

17,170 - 8,585 = 8,585 Additional interest paid using the new interest rate.

If the angle is preserved, which describes the effect of moving the plane closer to the cone's vertex? Check all that apply.
Sholpan [36]

Let's go though the choices.

Major axis will get shorter.  TRUE, CHECK ME

As the plane moves closer to the vertex the ellipse stays the same shape but shrinks.

Ellipse will become a circle.  FALSE

As long as the plane is tilted, the ellipse can't be a circle.

Ellipse will degenerate to a point.  TRUE, CHECK ME

Eventually the plane gets to the vertex, at which point (ha!) we have a single point.

Nappes?  Is that a word?   FALSE

The plane needs a steeper angle, steeper than the generators, before it can pass through both halves.

The generators are the lines through the vertex that form the cone.  The plane isn't steep enough to hold any of them. FALSE
