20x^5-8x^4 polynomial of the 5th degree, with two terms.

Distribute 4x^2(–2x^2 + 5x^3) to get –8x^2 + 20x^5. Reorder in standard form 20x^5-8x^4.  5 is the highest exponent so it is the 5th degree, there are two terms because terms are separated by a plus or minus.

Martin has 2 5/8 pounds of ground beef. He wants to divide the beef into equal sized portions to put into his freezer. The porti
Licemer1 [7]

Answer:

a) 7 equal sized pieces of 3/8 pounds

               7* 3/8 =  21/8

b) 3 equal sized pieces of 7/8 pounds

               3* 7/8 =  21/8

Step-by-step explanation:

Martin has 2 5/8 pounds of ground beef.

2 5/8 = 21/8 pounds = 2.625 pounds

Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations

a) 7 equal sized pieces of 3/8 pounds

               7* 3/8 =  21/8

b) 3 equal sized pieces of 7/8 pounds

               3* 7/8 =  21/8

Given the function f(x) = -2c+cx-x^2, and f^-1(5) = -1, find c
AnnZ [28]

Answer:

c=-2

Step-by-step explanation:

We are given the function:

f(x) = -2c + cx - x^2

And that:

\displaystyle f^{-1} (5) = -1

And we want to determine the value of <em>c</em>.

Recall that by definition of inverse functions:

\displaystyle \text{If } f(a) = b, \text{ then } f^{-1}(b) = a

So, since f⁻¹(5) = -1, then f(-1) = 5.

Substitute:

f(-1) = 5 = -2c + c(-1) - (-1)^2

Simplify:

5 = -2c - c - (1)

Combine like terms:

6 = -3c

And divide. Hence:

c = -2

In conclusion, the value of <em>c</em> is -2.
