Scientific notation is always between 1-10 times 10 to the power of how many decimal points it needs to be moved over
So the first number would be 9.25*10^-4. You can figure out the power by just moving the decimal over and count until the number is between 1 and 10
The index of radical expression is the number indicating which root (square root, cube root, etc.) is meant.
If there's no index on the radical expression, then it's assumed to be square root.

Law of cosines:
a^2 = b^2 + c^2 -2 *b*c*coa(a)
a^2 = 60.5^2 + 257^2 - 2*60.5*257*cos(31)
a^2 = 3660.25 + 66049 - 2 *60.5 * 257 * 0.857167
a^2 = 3660.25 + 66049 - 26655.33
a^2 = 43053.92
a = SQRT(43053.92)
a = 207.49 = 207.5 feet.
The answer is A.
Not sure but I believe letter B) 3+4 is rational since the answer is 7 and 7 is a rational number and it can be expressed as a quotient. The sum of a rational number and an irrational number is irrational. The sum of two rational numbers is rational
