Examples: 1  Find the periodic payment of an annuity due of $70000, payable annually for 3 years at 15% compounded annually. R = 70000/(1+ã(1-(1+((.15)/1) )ã^(-(3-1))/((.15)/1)) R = 70000/2.625708885. 2  Find the periodic payment of an annuity due of $250700, payable quarterly for 8 years at 5% compounded quarterly.
The next solar eclipse that can be seen in the United States and North America will be on August 21, 2017, NASA says. According to NASA, the solar eclipses in March will be a total eclipse, as will the August 2017 eclipse. The September 2016 and February 2017 eclipses will both be annular eclipses, which means a ring of sunlight will remain visible.
A total solar eclipse will take place on Monday, August 21, 2017. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide. This eclipse is the 22nd of the 77 members of Saros series 145, the one that also produced the solar eclipse of August 11, 1999.
