Lan wants to promote his band on the internet. site a offers website
hosting for $4.95 per month with a $49.95 startup fee. site b offers
website hosting for $9.95 per month with no startup fee. for how
many months would lan need to keep the website for site b to be less
expensive than site a?

Ian need to keep the website for site B less than 10 months

Step-by-step explanation:

Let

x -----> the number of months

y ----> the cost for website hosting

we know that

Site A

-----> equation A

Site B

-----> equation B

Equate equation A and equation B and solve for x

Round the number of months

For x=10 months ----> the cost for website hosting is the same in both sites

For x>10 months ---> the cost for website hosting is less expensive in site A

For x<10 months ---> the cost for website hosting is less expensive in site B

therefore

Ian need to keep the website for site B less than 10 months

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
