Answer:

A circle is shown. Secants P N and L N intersect at point N outside of the circle. Secant P N intersects the circle at point Q and secant L N intersects the circle at point M. The length of P N is 32, the length of Q N is x, the length of L M is 22, and the length of M N is 14.

In the diagram, the length of the external portion of the secant segment PN is X

The length of the entire secant segment LN is 36.

The value of x is 15.74

During the first quarter of the year, 351,875 people downloaded an app for their smartphones. During the second quarter of the y

Lina20 [59]

The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are 101,949 fewer people than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people

Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = 351,875 + 249,926 = 601,801 people

Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people
