I know this isn't helpful, but I REALLY need help on this question...

Given: f(x) = x^2 + 7x + 10. From the Rational Root Theorem, we know p=10 and q=1. List all potential roots using the ratio p/q.

Answer:

1. 16

2. -4

Step-by-step explanation:

First factor the expression

lim x→1 (x^3 + 5x^2 + 3x-9)/(x-1)

lim x→1 (x-1) (x+3)^2/(x-1)

Canceling the x-1 in the top and bottom

lim x→1 (x+3)^2

Let x=1

lim x→1 (1+3)^2 = 4^2 = 16

2. lim x→0 (x^2 -6x+8) /(x-2)

First factor the expression

lim x→0 (x-4) (x-2) /(x-2)

Canceling the x-2 in the top and bottom

lim x→0 (x-4)

Let x=0

lim x→0 (0-4) = -4

Filling in the table

x -.1 -.01 -.001 .001 .01 .1

f(x) -4.1 -4.01 -4.001 -3.999 -3.99 -3.9

What is 4 multiplied by 5 7/9 as a mixed number or fraction

Andrei [34K]

The answer is 23 and 1÷9

First you multiply 4 by 5 and wind up with 20
Then you multiply four by 7÷9.
That gets you 28÷9
You take out all the nines you can from 28, three in this case.
That gets you 27÷9 + 1÷9
Your total thing is 20+27÷9+1÷9
That equals 20+3+1÷9

A certain manufacturing company has the following data on quantities shipped and unit costs for each of its four products.

AnnyKZ [126]

Answer:

Paasche's Index= 168.63= 169

Step-by-step explanation:

Products

Base-Period Current Period

Quantities Mean Shipping Quantities Mean Shipping

(Year 1) Cost per Unit ($) (Year 5) Cost per Unit ($)

A 1,500 10.50 4000 15.90

B 5,000 16.25 3000 33.00

C 6,500 12.20 8000 18.40

D 2,500 20.00 3000 35.50

Paasche's Index= ∑ pn.qn/∑po.qn* 100

Where pn is the price of the current year and qn is the quantity of the current year and po. is the price of the base year and qo. is the quantity of the base year.

Paasche's Index is the percentage ratio of the aggregate of given period prices weighted by the quantities sold or consumed in the given period to the aggregate of the base period prices weighted by the given period quantities.

Multiplying the current year prices with the current year quantities and the base year price with the current year quantities we get.

Product pn.qn po.qn

A 15.90* 4000 10.50* 4000

= 63600 =42000

B 33.00*3000 16.25 * 3000

= 99000 = 48750

C 18.40* 8000 12.20 *8000

=147200 =97600

D 35.50* 3000 20.00*3000

=106500 60,000 

∑ 416300 248350

Paasche's Index= ∑ pn.qn/∑po.qn= 416300/ 248350 *100 = 1.676=1.68= 168.63= 169
