For those of you with differently ordered answers, the correct answers according to Apex are as followed: y=sec x and y=tan x
Answer:
a = π n for n element Z
Step-by-step explanation:
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
Solve this equation: $45 - ($2.75/pen)x = $12. Simplifying, we get
$33 = ($2.75)x, so that
x = $33 / ($2.75) = 12.
Tim's buying 12 pens leaves him with $12.
Answer:
x=0 x=2 x=7/2
Step-by-step explanation:
P(x) = 3x (x - 2) (2x - 7)
Set equal to zero
0 = 3x (x - 2) (2x - 7)
Using the zero product property
3x =0 x-2 =0 2x-7 =0
x=0 x=2 2x=7
x=0 x=2 x=7/2
Answer:
It is a 100% hope it helps
