Answer:

h(-3) = -27

Step-by-step explanation:

Given that,

h(x)=-2x^{(2)}+3x

We need to find the value of h(-3).

Put x = -3 in the given expression.

h(-3)=-2(-3)^{(2)}+3(-3)\\\\=-2\times 9-9\\\\=-27

So, the value of h(-3) is equal to -27.

Critical Thinking Explain how the formulas for the perimeter and area of a square may be derived from the corresponding formulas
vazorg [7]
The formulas for the perimeter and area of a square may be derived from the corresponding formulas for a rectangle because, like rectangles, squares are quadrilaterals, therefore sharing the same formal characteristics as a rectangle. They both contain a pair of lengths and a pair of widths, giving us 2-dimensional figures on a plane.

n200080 [17]

Answer:

1) Between 0 and 1 minute the rate of change is 25 ft./min

2) Between 1 and 2 minute the rate of change is 0 ft./min

3) Between 2 and 4 minute the rate of change is -12.5 ft./min

Step-by-step explanation:

1) Between 0, and 1 feet, we have;

The rate of change = (Final height - Initial height)/(Final time - Initial time)

The rate of change = (40 - 15)/(1 - 0) = 25 ft/min

Between 0 and 1 minute the rate of change = 25 ft./min

2) Between 1, and 2 feet, we have;

The rate of change = (40 - 40)/(2 - 1) = 0 ft/min

Between 1 and 2 minute the rate of change = 0 ft./min

3) Between 2, and 4 feet, we have;

The rate of change = (15 - 40)/(4 - 2) = -12.5 ft/min

Between 2 and 4 minute the rate of change = -12.5 ft./min
