The metal was prolly fake or whateva
We need to use the pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs, and c is the hypotenuse
47^2 + 18^2 = c^2
c = sqrt(2533)
c = 50.33
The length of the wire is 50.33 meters.
(See attached image.)
The answer is $19,360 because we multiply the annual interest rate of 6% or .06 by 3.5 years and we get a total interest of .21. The answer is found by performing $16,000 times 1.21 and we get $19,360.
Step-by-step explanation:
When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. But mainly completing the square is a technique that transforms your quadratic equation from an equation that can't be factored into one that can.
