The height of a dolphin jumping in and out of water, in feet,
can be modeled by the following function, where the x-axis
of the graph is the water line:
f(x) = -0.5x4 + 3.5x3 – 7x2 + 4x.
Which function reveals the moments when the dolphin
enters or leaves the water?

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

the first one, all those points on the line just make a strait line.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

50-60=10
