Answer:

392,730

Step-by-step explanation:

This increase will be over one year which will just be a 0.7% increase

to 390,000

0.7% of 390,000 is 2730

(0.007 * 390,000 = 2730)

390,000 + 2730 = 392,730

Or more simply we can add the increase in percentage to 1 for our multiplier

390,000 * 1.007 = 392,730

What is the perimeter of a right triangle whose hypotenuse is the line segment A(-7, 5) B(1,0)​
Svetradugi [14.3K]

Answer:

  it depends

Step-by-step explanation:

The endpoints of the hypotenuse are insufficient to specify a right triangle. The perimeter can range from twice the distance between these points, about 18.868 units, to 1+√2 times the distance between these points, about 22.776 units.

___

In the attached figure, the colored numbers are the total length of the two legs of that color. The hypotenuse and its length are in black.

_____

The distance between two points is given by the formula ...

  d = √((x2-x1)^2 +(y2 -y1)^2)

The perimeter will be the sum of the distances between pairs of points that define the vertices of the triangle. We need to know the third vertex to answer the question precisely.

If all the sides of a prism are multiplied by 5, by what factor does the volume increase?
NISA [10]
I'd say increasing each side by 5 increases the volume by a factor of 125 because 5*5*5 = 125.

Example:
A 4*5*6 prism has a volume of 120

Increasing each side by a factor of five
(20*25*30) = 15,000

15,000 / 120 = 125

balandron [24]

Answer:

2 + 0i

Step-by-step explanation:

Our real number in this scenario would be 2. And since we don't need an imaginary part because we are just converting 2 by itself, we plug in 0 for the imaginary number.
