If y varies inversely with the square of x, and y = 26 when x = 4, find y when x = 2.
eduard

Answer:

D. 104

Step-by-step explanation:

y \:  \alpha  \:  \frac{1}{ {x}^{2} }  \\  \\ y =  \frac{k}{ {x}^{2} }

when y is 26, x is 4:

26 =  \frac{k}{ {(4)}^{2} }  \\ k = 416

when x is 2:

y =  \frac{416}{ {x}^{2} }  \\ \\ y =  \frac{416}{ {(2)}^{2} }  \\ y = 104

Marianna [84]

Answer: $10988.25

Step-by-step explanation:

From the question, we are told that for the Black Panther trip 420 students were scheduled to go and 15% more students were selected. This means that the total number of students that are going will be:

= 420 + (15% × 420)

= 420 + (0.15 × 420)

= 420 + 63

= 483 students

Since each administration ticket cost 22.75 dollars. The total amount paid for all tickets purchased will be:

= 483 × $22.75

= $10988.25
