Determine whether the progression above is arithmetic, geometric, harmonic, or none of the above. If arithmetic or harmonic, state the common difference, d. If geometric, state the common ratio, r. 50, -10, 2, …

Use the quadratic formula to solve for x:  2×2 + 4x – 30 = 0

Use the quadratic formula to solve for x :  2×2 + 10x – 28 = 0

Suppose a floor plan has a length of 34 ft. Using Alberti’s recommendations, find the width of the floor plan, using the octave. Round to one decimal place and type just the numeric value below.

Consider this problem: If 15 pints of ice cream costs a baker $75, how much will 18 pints cost? Choose one of the following methods to solve the problem: (a) The Rule of Three or (b) Proportions Be sure to show ALL work! Again, you only need to solve using one of the methods! Round this answer to two decimal places.

Determine whether the following progression is arithmetic, geometric, harmonic, or none of the above. If arithmetic or harmonic, find the common difference, d. If geometric, find the common ratio, r.
