Answer:
Your first 2 questions are correctly answered.
I think the answer to the third question is NO.
Step-by-step explanation:
You can see that the sides with 3 and 4 are adjacent, which means they cannot possibly be opposite. For a valid dice, they should be opposite because they add up to 7. Hence this net is not valid.
Answer:
204.4 amu
Step-by-step explanation:
0.30 * 203 = 60.9
0.70 * 205 = 143.5
60.9 + 143.5 = 204.4 amu
I hope this helps!
In order to prove the triangle is a right angled triangle we need to prove that the slope of the lines CA and BC and AB have any negative reciprocals.Lets find the slopes .
AB=(-1,3), (1,2) slope of AB = 2-3/1-(-1)= -1/2 slope of AB is -1/2
BC = (1,2), (-3,1) slope of BC is 1-2/-3-1= -1/-4 slope of BC is 1/4
Slope of CA =(-3,1)(-1,3) slope of 3-1/-1-(-3)=-2/-2=1
Since the slopes do not have any negative reciprocals so the triangle is not a right angled triangle
The answer would be 20 over 1 bevause if you do 20 ×1 you get 20. So the would be 20 over 1.
Absolute value function domain is all real numbers
absolute value has vertex of(0,-3)
and it opens up
means that the lowest y value is -3
highest is infinity
domain=-inifnity to infinity
range=-3 to positive initnify
the answer is C for the domain and B for the range
