How many of the first million positive integers share no common factors greater than 1 with 2020
Bingel [31]

9514 1404 393

Answer:

  396,040

Step-by-step explanation:

Factors of 2020 are 2, 5, 101.

There are 1,000,000 / 1010 = 990 multiples of 2 and 5 and 101.

There are 1,000,000 / 505 -990 = 990 multiples of 5 and 101 only.

There are 1,000,000 / 202 -990 = 3,960 multiples of 2 and 101 only.

There are 1,000,000 / 10 - 990 = 99,010 multiples of 2 and 5 only.

There are 1,000,000 / 101 -990 -990 -3960 = 3,960 multiples of 101 only.

There are 1,000,000 / 5 -990 -990 -99,010 = 99,010 multiples of 5 only.

There are 1,000,000 / 2 -990 -3960 -99,010 = 396,040 multiples of 2 only.

So, the total number of multiples of any factor of 2020 is ...

  990 +990 +3960 +99,010 +3960 +99010 +396040 = 603960

Then the number of integers in the first million that do not share any common factors greater than 1 with 2020 is ...

  1,000,000 -603,960 = 396,040

I need to know how to work following problem: union motion- A small airplane approaches a runway at a speed of 90 miles per hour
alex41 [277]
First lets convert everything to feet, and feet/min

1/2 mile = 5280/2 = 2640 feet
90 mi/hr = (90)(5280)/(60) = 7920 ft/min

Next lets find total distance plane is away from runway.
Set up right triangle where total distance is hypotenuse.
d = \sqrt{200^2 + 2640^2} = 2647.5649

Next we will use a little trig. Let theta be the angle of elevation from runway to the plane. The rate of descent is the vertical component of the planes speed. Find vertical component using sine.
\frac{dy}{dt} = 7920 sin \theta

Finally substitute ratio from right triangle for sin theta.
\frac{dy}{dt} = 7920 (\frac{200}{2647.5649}) = 598.286

The rate of descent is about 598 feet per minute.
