By graphing the given points, we will get the attached figure
which represents:
                                          f(x) = 3 sin x
but sin x = cos (x - π/2)
                                     ∴  f(x) = 3 cos ( x - π/2 )

The correct choice is option ⇒⇒⇒ <span>f(x) = 3 cos(x − pi over 2 ) </span>

Which answer is correct
andre [41]

Hello from MrBillDoesMath!

Answer:

The first choice,  Pi + (-Pi) = 0

Discussion:

Pi is an irrational number. Saying the irrational numbers <u>are</u> closed under addition means if we add two irrational numbers we will get another irrational number. In our case, Pi + (-Pi) = 0, which is correct, BUT 0 is a <u>rational </u>number. This shows the set of irrational numbers is NOT closed under addition.

Thank you,

MrB

A line goes through the point (6,-2) and has a slope of
Lilit [14]

Answer: a = 3

Step-by-step explanation: when you multiply 6 by -3 you get -18 and if you add 16 you get -2

so the slope is -3 and the y-intercept is 16

so a*-3 + 16 = 7

by subtracting 16 on both sides you get

-3a = -9

and to get a by itself you divide -3 on both sides

a = -9/-3

a= 9/3

a = 3
