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.

Complete the table so that the cost per banana remains the same.
Aneli [31]

Step-by-step explanation:

No. of banana    Cost      Unit price

4                            2            0.50

6                            3             0.50

7                           3.5           0.50

20                         10            0.50

20                          10             0.50

33                          16.50        0.50

Cost = No of banana x unit price

Cost = 4 x 0.50 = 2

Cost = 6 x 0.50 = 3

Cost = 7 x 0.50 = 3.50

Cost = 20 x 0.50 = 10

No of banana = Cost / Unit price

No of banana = 10 / 0.50 = 20

No of banana = 16.50 / 0.50 = 33

What is the answer to linear equation: 5 = 6 - 7c
nadya68 [22]

Answer:

c = 1/7

Step-by-step explanation:

Here we have to solve the linear equation.

We need to find the value of c.

5 = 6 - 7c

Isolate the variable and constants

Add 7c on both sides, we get

7c + 5 = 6 - 7c + 7c

7c + 5 = 6

Subtract 5 from both sides, we get

7c + 5 - 5 = 6 - 5

7c = 1

Dividing both sides by 7, we get

c = 1/7

Thank you.

Maksim231197 [3]
This should be recognized as the difference of perfect squares which is of the form:

(a^2-b^2) and the difference of squares always factors to:

(a-b)(a+b)  in this case:

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If
Nataly [62]

Answer:

The function is missing in the question. The function is $ C(x) = 0.8x^2 -544x +97410 $

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$ C(x) = 0.8x^2 -544x +97410 $

Cost will be minimum when

x = -(-544)/ 2 x 0.8

  = 340

Therefore, minimum cost for unit car is

$ C(x) = 0.8x^2 -544x +97410 $

$ = 0.8(340)^2 -544(340) +97410 $

=  4930
