scoundrel [369]

Answer:

Step-by-step explanation:

No, this doesn't make sense because as stated in the problem, each ticket costs $2.50. Since you cant buy part of a ticket, you would have to have a whole number for t. You cannot buy 3.5 tickets.

Answer: $f'(1)=\dfrac{4}{2y+1}$

<u>Step-by-step explanation:</u>

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given: 0 = 2x² - xy - y²

Derivative: 0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

y'(2y + 1) = 4x

$y'=\dfrac{4x}{2y+1}$

$\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}$

garik1379 [7]

Answer:

18.75%

Step-by-step explanation:

percent increase = $\frac{increase}{original cost}$ × 100%

Increase in cost = $38 - $32 = $6

percent increase = $\frac{6}{32}$ × 100% = $\frac{6(100)}{32}$ = 18.75%
