Answer: A fireworks shell is shot straight up with an initial velocity of 80 feet per second. Its height s after t seconds is given by the equation
s = 80t − 16t2.
Step-by-step explanation:
The length is 10 because 10x4=40. 10-4=6. 10 is 6 units greater than 4, the width being 4. therefore, the length is 10 units and the width is 4 units. Hope I helped!
The discriminant D is found by this formula
D = b^2 - 4ac
there are 3 possible outcomes
1) If D is smaller than 0, ie D < 0, then there are no roots
2) If D is equal to zero (D = 0), then there is exactly one root. This root is rational assuming the coefficients are integers. This is called a double root
3) If D > 0, then there are 2 different roots. If D is a perfect square, then these two roots are rational numbers (aka fractions of whole numbers) assuming the coefficients are integers. If D is not a perfect square, then the two roots are irrational numbers.
