Algebra 1. questions 2-4. answering any would be awesome!

2.
6pink 7purple. total count 13.

without replacement draws 1 and then another. (odds of drawing purple)
first draw 7/13
second draw 6/12

7/13•6/12 = 42/156 or 21/78 or 7/26

with replacement.
first draw 7/13
second draw 7/13

7/13•7/13 = 49/169

3.
total $8.40, p=n-60

60•5¢= $3.00

$8.40-$3.00=$5.40
1¢+5¢= 6¢

$5.40/6¢=90¢

1¢•90=90¢
5¢•90=$4.50

150•5¢=$7.50
90•1¢= $0.90

$7.50+$0.90=$8.40

The correct answer option is tan x and cot x.

Range is the values of y which a function can take so range of tan x and cot x are all real numbers.

Period of tan x and cot x is .
