Answer:

x^3+6x^2-17x+2

Step-by-step explanation:

(x-2)*(x^2+8x-1)

=x(x^2+8x-1)-2(x^2+8x-1)

=x^3+8x^2-x-2x^2-16x+2

collect like terms

= x^3+6x^2-17x+2

If r(X)=2-x^2 and w(X)=X-2, what is the range of (w*r)(X)
slega [8]
The given function are
r(x) = 2 - x²    and     w(x) = x - 2
<span>(w*r)(x) can be obtained by multiplying the both function together
</span>
So, <span>(w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)</span>
<span>(w*r)(x) = x (2-x²) - 2(2-x²)</span>
            = 2x - x³ - 4 + 2x²

∴ <span>(w*r)(x) = -x³ + 2x² + 2x - 4
</span>

<span>It is a polynomial function with a domain equal to R
</span>
The range of <span>(w*r)(x) can be obtained by graphing the function
</span>
To graph (w*r)(x), we need to make a table between x and (w*r)(x)

See the attached figure which represents the table and the graph of <span>(w*r)(x)
</span>

As shown in the graph the range of <span>(w*r)(x) is (-∞,∞)
</span>

There are fifteen teams in a high school baseball league. How many different orders of finish are possible for the first four ​p
ankoles [38]
There are 32,760 different orders for the first four positions.

This is a permutation where repetition is not allowed; the formula for that is:

_nP_r=\frac{n!}{(n-r)!}

For our problem, we have:
_{15}P_4=\frac{15!}{(15-4)!}=\frac{15!}{11!}=32760

Your history test is out of 30 points. How many points would you need to get if you wanted a ‘B’ or higher? (Hint: A grade of 80
Sloan [31]
To get a B, you need at least 80%.

30 x 0.8 = 24

80% of 30 is 24, so you would need to get at least 24 points <3
