So this problem is asking you to plug numbers in for t. 0 1 2 3 4 5. So your first equation would be 2× 0+8 and you would get 8 so for 0 toppings you would pay 8 dollars then graph this over 0 up 8. Next equation 2×1+8 is 10. Graph. over 1 up 10. Next 2×2+8 is 12. Graph. Over 2 up 12. next 2× 3 + 8 is 14. Graph. Over 3 up 14. Next 2×4+8 is 16 so over 4 up 16. Last 2×5+8 is 18 so over 5 up 18. Your Y-intercept is the dot that is on the y axis and in this problem that is 8. This means if you buy 0 toppings you will spend 8 dollars.

Solve the equation x4 – 26x2 + 25 = 0 in the real number system.
gogolik [260]

Answer:

x = -1, 1, -5 , 5.

Step-by-step explanation:

x4 – 26x2 + 25 = 0

Factoring:

(x^2 - 25)(x^2 - 1) = 0

So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.

x^2 - 1  gives  x^2 = 1 and x = +/- 1.

kykrilka [37]

Answer:

By eliminating Linens department net operating income fell by $574,800.00

Step-by-step explanation:

The question requires that the monthly contribution income statement be prepared when the Linens is closed or eliminated,incorporating the unavoidable fixed costs of $373,000 as well as the fall in sales of Hardware by 15%.

             Monthly Contribution Income Statement:

Sales($3,110,000)*(1-15%)                               $2,643,500.00  

Variable expenses($858,000)*(1-15%)          ($729,300.00)

Contribution margin                                        $1,914,200.00  

Fixed expenses($1,480,000+$373,000)      ($1,853,000.00)

Net operating income                                        $61,200.00  

Reduction in net operating=$636,000-$61,200.00=$574,800  

Alternatively:

Lost contribution from closing Linens department    $674,000.00

Lost contribution from Hardware(15%*$2,252,000)   $ 337,800.00  

Total lost contribution                                                   $1,011,800.00  

Less avoidable fixed costs($810,000-$373,000)         ($437,000.00)

Reduction in profits company-wide                                $574,800.00
