Put 3/8, 2/5, and 0.38 from least to greatest
Vesnalui [34]
3/8=0.375
2/5=0.4
0.38=0.38

0.375<0.38<0.4

therefore: 3/8,0.38,2/5

*Remember that you can convert fractions to decimals by dividing the numerator by the denominator! This makes it much easier to compare :)

The vertex of a parabola is (0,0)and the focus is (1/8, 0) . What is the equation of the parabola?
Aleonysh [2.5K]

The equation of a parabola whose vertex is (0, 0) and focus is (1 / 8, 0) is equal to x = 2 · y².

<h3>How to derive the equation of the parabola from the locations of the vertex and focus</h3>

Herein we have the case of a parabola whose axis of symmetry is parallel to the x-axis. The <em>standard</em> form of the equation of this parabola is shown below:

(x - h) = [1 / (4 · p)] · (y - k)²     (1)

Where:

  • (h, k) - Coordinates of the vertex.
  • p - Distance from the vertex to the focus.

The distance from the vertex to the focus is 1 / 8. If we know that the location of the vertex is (0, 0), then the <em>standard</em> form of the equation of the parabola is:

x = 2 · y²     (1)

The equation of a parabola whose vertex is (0, 0) and focus is (1 / 8, 0) is equal to x = 2 · y².

PLEASE HELP
katovenus [111]

<u>Answer:</u>

$593.26

<u>Step-by-step explanation:</u>

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = \frac{75}{100} *2500 = $1875

for 2nd year =  \frac{75}{100} *1875 = $1406.25

for 3rd year =  \frac{75}{100} *1406.25 = $1054.7

for 4th year =  \frac{75}{100} *1054.7 = $791.01

for 5th year =  \frac{75}{100} *791.01 = $593.25

Or we can use the following formula to find its resale value after 5 years:

2500*(0.75)^5 = $593.26
