Answer:

C

Step-by-step explanation:

To find the x- intercept let y = 0, hence

cos(\frac{x}{2}) = 0

\frac{x}{2} = cos^{-1}(0 ) = \frac{\pi }{2}

multiply both sides by 2

x = π ← x- intercept

Wilhelmina wrote a check for $72 to pay her monthly Internet bill, but when
lesantik [10]

Answer:

her bank statement will show that she has $144 less than her checkbook balance

Step-by-step explanation:

let the amount of money in the bank before writing the check be x

after writing the check for $72, because she accidentally recorded this as a credit, here checkbook will reflect a balance of :$(x + 72)

However, the bank correctly records the debit of the $72, resulting  a balance of: $(x-72)

Hence compared to her checkbook,  the bank records will show an amount difference of :

(x-72) - (x + 72)

= x - 72 -x -72

= -144

i.e her bank statement will show that she has $144 less than her checkbook balance
