Use scientific notation to estimate the number of inches in 1,225 miles.
Zolol [24]
In scientific notation, to obtain the original whole number. Move the decimal to the left if the exponent is negative and to the right if the exponent is positive.
So 1 inch = .00001578 miles
1225 / .00001578 = 77629911.28

To obtain the answer in scientific notation, move the decimal to the left until you have a single digit whole number and the rest of teh digits are to the right of the decimal. In this case 7 places. Now show it multiplied by 10 to an exponent equal to the number of places you moved the decimal. In this case the 7th exponent.

Which are the solutions of the quadratic equation? x2 = 9x + 6
Lelechka [254]
X^2 = 9x + 6
x^2 - 9x - 6 = 0
use quadratic formula : (-b (+-) sqrt b^2 - 4ac) / (2a)
a = 1, b = -9, c = -6
now we sub

x = (-(-9) (+-) sqrt -9^2 - 4(1)(-6)) / 2(1)
x = 9 (+-) sqrt 81 + 24)/2
x = 9 (+-) sqrt 105) / 2
x = 9/2 + 1/2 sqrt 105 or x = 9/2 - 1/2 sqrt 105
