Answer:

To know how much he bought it for, let's consider the actual amount it be x.

Step-by-step explanation:

10% of x + $585 = x

x/10 + $585 = x

$585 = x-x/10

$585= 9x/10

9x=$5850

x=$5850/9

x=$650

.: the actual price was $650.

Answer:

Blue Star

a.                                   The Ford TriVan   The Honda CityVan

Total life-cycle costs          $94,368                $90,936

Based on life cycle cost, the Honda CityVan is the best choice.

b. Blue Star needs to put on the Ford TriVan 9,032 miles more for the cost to be equal with the Honda CityVan's.

c. The crossover point in years = 5 months

Step-by-step explanation:

a) Data and Calculations:

                                        The Ford TriVan   The Honda CityVan

Purchase costs                  $28,000                 $32,000

Fuel efficiency per gallon   24 miles                 37 miles

Operating cost per mile     $0.20                     $0.22

Total operating costs         $4,400                   $4,840

Estimated annual distance 22,000 miles        22,000 miles

Gallons of fuel consumed  916.7 (22,000/24) 594.6 (22,000/37)

Total cost of fuel                 $3,896                  $2,527

Fuel cost per mile              $0.18                      $0.115

Total cost per mile             $0.38                     $0.335

Expected life of truck         8 years                   8 years

Average gas price = $4.25 per gallon

Total costs:

                                        The Ford TriVan   The Honda CityVan

Annual costs:

Total operating costs         $4,400                   $4,840

Total cost of fuel                $3,896                   $2,527

Annual costs                      $8,296                   $7,367

Life cycle costs:

Annual costs for 8 years   $66,368                $58,936

Purchase costs                  $28,000                $32,000

Total life-cycle costs          $94,368                $90,936

Difference in costs between Ford TriVan and Honda CityVan = $3,432 ($94,368 - $90,936)

Miles to put on the Ford TriVan for the life cycle cost to be equal to the life cycle cost of the Honda CityVan

= Difference in costs divided by total cost per mile of the Ford TriVan

= 9,032 miles ($3,432/$0.38)

Annual distance = 22,000 miles

Monthly distance = 1,833 miles

9,032/1,833 = 4.93 months or 5 months approximately

Show that (x+1) is a factor of f(x)=19x^42+18x-1
Dmitry_Shevchenko [17]

Answer:

see explanation

Step-by-step explanation:

If (x + 1) is a factor then f(- 1) = 0

f(- 1) = 19(-1)^{42} + 18(- 1) - 1 = 19 - 18 - 1 = 0

Thus (x + 1) is a factor of f(x)

Can someone please HELP me on how to do this
frutty [35]

Answer:

4)x= g-c

5)x =u+k

6)x = g-c

7)a=\frac{k}{u}

8)x= \frac{g}{c}

9)a=\frac{4}{12m}

10)x= \frac{2c+3}{3}

11)a=\frac{n+p}{m}

12)a= \frac{ub}{k}

13)a= d -r + c

14)x=\frac{np}{m}

Step-by-step explanation:

4) g= c+x

x= g-c

5) u=x-k

x =u+k

6)g = c+x

x = g-c

7) u=\frac{k}{a} \\\\a=\frac{k}{u}

8) g=xc

x= \frac{g}{c}

9) 12am = 4

a=\frac{4}{12m}

10)-3x+2c = -3

2c = -3 +3x

2c +3 = 3x

x= \frac{2c+3}{3}

11) am= n+p

a=\frac{n+p}{m}

12)u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}

13)a-c = d-r

a= d -r + c

14)xm= np

x=\frac{np}{m}
