Answers

Multiply 800 to 4/5 to see how much they make per day.

800 * 4/5 = 640

So they make 640 fishing reels per day.

Multiply this to 30:

640 * 30 = 19,200

So they will make 19,200 fishing reels in 30 days.

This is not enough for the order.

The factory normally produces 800 reels a day.
They have to cut their production by 1/5, however.
800 * 4/5 = 640 reels a day.

30 days would mean 640 * 30 reels...19200 reels.

This is less than 20,000, so the factory will NOT be able to produce enough reels.

D- x5−4x4−2x3−2x2+8x
E- 8x+x5−2x2−2x3−4x4

Answers

For this case we have the following polynomial:

$P (x) = - 2x ^ 2-4x ^ 4 + 8x + x ^ 5-2x ^ 3$

By definition, a polynomial in its standard form is given by:

$f (x) = ax ^ n ... + bx ^ i + ... cx ^ 3 + dx ^ 2 + ex + f$

Where:

a, b, c, d, e, f: They are the coefficients of each term of the polynomial.

x: It is the variable

n, i, 3,2,1,0: They are the exponents of each term of the polynomial, where n is the exponent of greater degree.

In this case they ask us to order the given polynomial, in a descending way, that is, from greater to lesser degree.

So, we have:

$P (x) = x ^ 5-4x ^ 4-2x ^ 3-2x ^ 2 + 8x$

Thus, the polynomial in its descending form is given by:

$P (x) = x ^ 5-4x ^ 4-2x ^ 3-2x ^ 2 + 8x$

Step-by-step explanation:

Ernesto is shopping at store that is having a clearance sale. The price of everything in the store is discounted by 25%. If Earnesto buys a shirt originlly priced at $22.00 and a 6% salse tax is dded, what will be the total price of the shirt?$16.50

$17.49

$29.15

$23.10

$18.66

Answers

$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.
