79
A landscaper has 50 feet of landscaping timbers with which to make a rectangular flower bed. He wants a flower bed that has an area of 150 square feet. The equation L(L - 5) = 150 gives the length of the flower bed that meets these requirements. Use the discriminant to determine if these requirements for the flower bed can be met. Justify your answer. F. Since the discriminant is zero there are no real solutions. Therefore, there is no length that can be used with only 50 feet of landscaping timber. G. Since the discriminant is positive, there are 2 real solutions and the positive solution is the length that can be used with only 50 feet of landscaping timbers. H. Since the discriminant is negative the equation has no real solutions. Therefore, there is no length that can be used with only 50 feet of landscaping timbers. J.Since the discriminant is negative the equation has one real solution with a multiplicity of 2. This solution is the length that can be used with 50 feet of landscaping timbers.

This represents the minimum temperature during the time period. This minimum occurs at 128 minutes. H. Maximum - The maximum is 5 degrees. This represents the maximum temperature during the time period. This maximum occurs at 128 minutes. J.Maximum - The maximum is 128 degrees. This represents the maximum temperature during the time period. This maximum occurs at 5 minutes.
