Answer:
Whats the percentage of the VAT?
Answer:
-3
Step-by-step explanation:
The average rate of change from point (x1, y1) to point (x2, y2) is given by ...
m = (y2 -y1)/(x2 -x1)
For the given points, this is ...
m = (2 -14)/(6 -2) = -12/4 = -3
The average rate of change on the interval is -3.
Law of cosine:
c² = a² +b² -2ab*cosC.
Because the triangle is equilateral a=b=c=x,
and we can write,
x²=x² +x² -2xx*cosC
x² =2x² -2x²* cos C
-x² = -2x²*cos C
cos C= 1/2,
so m∠C=60⁰.
Because all sides are equal, and across of the equal sides should be equal angles, all angles will be also equal and = 60⁰.
Answer:
Two pairs are B,C and A,E
Step-by-step explanation:
The reasons why are because they intersect with other angles.
She accumulated an average rate of 12 CDs each year. You find this by subtracting 47 from 83 which gives you 36, dividing it by 3, which gives you 12.
