what is the question? if u give the question , I might help and edit this :)
Step-by-step explanation:
Model:
s = slices
x = pizzas ordered
s = .8(.45x) + .12(.55x)
Now plugin 20 for x and you will get the total number of slices.
s = .8(.45x) + .12(.55x)
s = .8(.45(20)) + .12(.55(20))
s = 204 slices
Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem
Answer:
-(135/31), 60/31
Step-by-step explanation:
y=60/31
x=-(135/31)
Answer:
-18
Step-by-step explanation:
F(x)=-2x^2
f(-3) means substitute x with -3
= -2(-3)^2
= -18

Check the picture below.
in the picture below, the bottom part
notice, 69° + 21° = 90°, so 21° and 69° are really complementary angles, sharing the same quadrant, meaning for any two sides of lengths say, a,b one angle will have a tangent of say b/a, then the other will have a tangent of a/b.
namely the tangent of each angle, is simply the other's tangent upside-down.
