To answer this, we need to see the polynomial. Descending order is in a way that the first term of the polynomial will be three, the second (in descending order, two....and so on).

420t+20t3-210t2

In descending order is:

20t^3 - 210t^2 + 420t

So, the option is number two.

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in th
Vesna [10]

Answer:

Step-by-step explanation:

Average rate of change is the same thing as the slope.  Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function.  But we can use the same idea.  When t = 3, h(t) = 33, so the coordinate point is (3, 33).  When t = 6, h(t) = 0, so the coordinate is (6, 0).  Plug those values into the slope formula:

m=\frac{0-33}{6-3} and

m=\frac{-33}{3} which is -11

From 3 to 6 seconds, the rocket is falling 11 yards per second.

ANTONII [103]

Answer: 10 units²

Step-by-step explanation:

We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.

We can get each triangle's area using the formula A = \frac{1}{2}bh

<h3>Left Triangle</h3>

base length - 4 units

height - 4 units

A = \frac{1}{2}(4)(4)

A=\frac{1}{2}(16)

A =8\hspace{0.1cm}units^2

<h3>Right Triangle</h3>

base length - 2 units

height - 2 units

A = \frac{1}{2}(2)(2)

A=\frac{1}{2}(4)

A=2\hspace{0.1cm}units^2

Total = 8 units² + 2 units² = 10 units²
