Answer:To find this, all you have to do is plug in 3 where x is in the equation, which gives you this:
f
(
3
)
=
5
(
3
)
−
2
. From there, just find the value:
5
(
3
)
−
2
=
13
.
Step-by-step explanation: 13 is the answers sorry i looks like that
Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
Answer:
look below
Step-by-step explanation:
thing to note:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite= side across angle you are using
hypotenuse= side across 90 degree angle
adjacent= remaining side
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6
hope that helped. let me know if you have any questions:)
Answer:
I can't draw the graph for you here, but the y intercept is 3, and the slope is -1.
Step-by-step explanation:
First you plot a point on the y axis at 0,-3
Then you want to do a rise over run, doing -1,1 until you get enough points to graph the line.
