Answer: 135
Step-by-step explanation: 12.5 percent of 120 is 15, so just add that to 120
The number is 225.
It square roots are +15 and -15 .
They are 30 apart on the number line.
29029 in scientific notation is 2.9029 x 10 ^ 4
Is this for calculus for for algebra?
I'm going to assume that you know calculus.
df
---- = 2ax + b must equal zero if (-1,2) is an extreme value of f(x).
dx
Thus, 2ax + b = 0, and 2ax = -b, or x = -b/(2a). This is the familiar "x-coordinate of the vertex of a parabola."
Here that x-value is -1, so -1 = -b/(2a). From this we get -2a = -b, or
b=2a
so the ordered pair could be (a, 2a).
