The parks department has started building a new playground at Canyonside Park. The shape of the playground is shown below. A playground is made up of a rectangle and a triangle. The rectangle has a base of 36 feet and a height of 10 feet. The triangle has a base of 36 feet and a height of 14 feet. The supervisor needs to purchase wood chips to cover the ground in the playground area. If wood chips are sold in bags containing enough to cover 4 square feet and these bags cost $8.00 apiece, how much will it cost to cover the entire area of the playground with wood chips? $612.00 $1,224.00 $1,728.00 $4,896.00

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

pls refer ro the top for answer

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
