y = arcsinx and y = arccosx
y = arcsinx and y = arctanx
y = arctanx and y = arcsecx
y = arccosx and y = arcsecx

D

arcos x and arcsec x have the same maxiumum

Step-by-step explanation:

just took the quiz on edge

D.  y = arccosx and y = arcsecx

Step-by-step explanation:

got it right on edge :)

$13.75

Step-by-step explanation:

Since Mrs. Chin paid a 20 percent tip on the bill for lunch and the tip amount was $2.75, then the bill for lunch before the tip was added to it will be calculated thus:

Let the bill for lunch be represented by x. Therefore,

20% of x = $2.75

20/100 × x = $2.75

0.2 × x = $2.75

0.2x = $2.75

x = $2.75/0.2

x = $13.75

Therefore, the bill is $13.75 before the too was added.
