a x b = -3. b x b = 1. Now whats -3 - 1? When a letter is right next to another letter without a space, that means it wants you to multiply the value of one letter by the other. for example, if x equals 2 and y equals 3, and they're right next to each other like this: xy that means you need to multiply x by y. X times Y = 2 times 3. 2x3=6. If you see a letter with a small number beside it, this means that it wants you to multiply the value of that letter by itself times the little number on the top. For example, if n equals 6, and the little number on the top right is 3, then that means you have to multiply 6 by 6 three times. 6 x 6 x 6 = 216.
Use the Pythagorean Theorem.
a^2 + b^2 = c^2
a^2 + 12^2 = 19^2
Simplify the exponents:
a^2 + 144 = 361
Subtract 144 to both sides:
a^2 = 217
Find the square root of both sides:
a = 14.73
The rate of change is the slope.
slope = m = (-11 - (-1))/(2 - 0) = (-11 + 1)/(2) = -10/2 = -5
The initial value is the y-intercept. The y-intercept is (0, -1), so the initial value is -1.
