Your cell phone plan cost $39.99 per month plus $.13 for each text message you send or receive. You have at most $45 to spend on
Dafna11 [192]

Answer:

At most 38 text messages.

Step-by-step explanation:

Let x represent number of text message you send or receive.

We have been given that the cell phone plan charges $.13 for each text message you send or receive. So amount charged for sending or receiving x text messages would be 0.13x.

We are also told that your cell phone plan cost $39.99 per month, so total cost of monthly bill would be 0.13x+39.99.

Since you can spend at most $45, so total cost of x messages should be less than or equal to 45 as:

0.13x+39.99\leq 45

0.13x+39.99-39.99\leq 45-39.99

0.13x\leq 5.01

\frac{0.13x}{0.13}\leq \frac{5.01}{0.13}

x\leq 38.5384615

Therefore, you can send or receive at most 38 text messages.

Convert y=9 from rectangular to polar form
Crazy boy [7]

Answer:

r = 9/sin Ф or r = 9 csc Ф

Step-by-step explanation:

The polar form is represented as:

x = r cos Ф and

y = r sin Ф

We are given:

y = 9

Putting value in y = r sin Ф

9 = r sin Ф

=> r = 9/sin Ф

1/sin Ф = csc Ф

or, r = 9 csc Ф
