How do you solve 2b2 plus 5b-35?
Assuming the equation is 2b2+5b-35=0, the quadratic formula is one way to solve this equation. It can't be factored easily. Do not confuse the "b" variable in the formula given with the "b" in the related link. The values of a, b, & c are as follows to be used in the quadratic formula: a=2, b=5, c= -35. Placing these values in the quadratic formula gives: (-5+/- sqrt(52-4*2*(-35)))/(2*2). This yields variable b = (-5+/- sqrt(305))/4 or (-5+17.46425)/4 & (-5-17.46425)/4 = 3.11606 & -5.61606 which are the two roots of the given equation.
What is the geometric mean for 3 and 12?
Per the formula in the related link, substitution into the formula yields (3*12)1/2, which is (36)1/2 or 6.
Derive the formula for radius if the formula is c equals pi times r squared?
Where pi (~ 3.1416) is represented by π, The formula C= πr2 yields the formula r2 = (C/π) therefore r = square root (C/π). ...which is the same as : r = (C/π)1/2.
What is the volume of a right circular cylinder with a radius of 6 and height of 10?
The formula is pi X radius2 X height. Application of this formula yields a value of about 1.130973355 X 103 of the cubic units corresponding to the length unit for the radius and height.
What is the quick formula of percentage?
It's a fraction, like 5/10 or 1/2 or... divide the numerator by the denominator. Example: 5 divided by 10 or 1 divided by two. This yields the simple percentage.

How can you tell when a quadratic equation has two identical rational solutions?
When b^2=4ac the zero is at a single point. The parabola does not penetrate the x axis. This represents two zeros, both with the same value. Example: x^2+4x+4 yields two zeros, each at x=-2. Notice that b^2=16=4ac. So Bob's your uncle!
