What is the radius of a sunflower with a circumference of 46 cm?
The formula is: circumference = 2 x pi x radius. As always when you use a formula, plug in the values you know and solve for the ones you don't. So plug in 46 for the circumference and solve for the radius. (You'll get that the radius = (circumference)/(2pi)).
How do you solve for one time constant?
You can solve for a one-time constant by using the formula t = RC. Read the math problem you are given carefully to determine what values to plug into the equation.
How do you perform the quadratic formula?
Put the equation into the following form: ax2+bx+c=0 Then plug the values for a, b, and c into the quadratic formula. Do the arithmetic to find the value for x twice, once using + after the -b in the numerator, and once using - after -b in the numerator. You will get two different values for x, one using + and the other using -. Give both possible values for x when you give your answer. Here is the quadratic formula: x= -b+-square root(b2-4ac)/2a
Why would you want to solve a literal equation for a variable when you could simply plug in known values and then solve the resulting linear equation?
if you solve by plugging in the known values ahead of time you won't have a general formula for the variable in the literal equation. Therefor if the known values change, you would have to start all over again, making each problem more individualized. Once the literal equation is solved for some variable, if the known values change all you have to do is plug in those new numbers to your literal equation, and out pops your answer
What is the perimeter of the rectangle with a length of 8 inches is 48 square inches?
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
