Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
We have
(a, b ) → (a, - b ) ← reflection in the x- axis
If you would like to know how many pieces can be made from each rod, you can calculate this using the following steps:
49 metre long / 1 metre = 49 / 1 = 49 pieces
The correct result would be 49 pieces.
Diana had chocolate, and ate some, leaving 0.75 of it for Sarah.
Sarah ate 18.5 grams of it and return the rest to Diana, which was 65% of the original chococate.
how much chocolate did Diana have at the beginning?
and the solution is:
0.75x-18.50=0.65x
0.75x-0.65x=18.50
0.1x=18.50
x=185
so Diana had 185 grams of chocolate.
Answer:
C
Step-by-step explanation:
Using the law of cosines then cosΘ is the following quotient
cosΘ = 
where a = 5.8, b = 10.5 and c = 10.9
cosΘ = 
= 
= 
= 0.21 → C
Answer A
They have the same x-intercept but different end behavior as x approaches ∞ :)
