Answer:
40% as a fraction is 4/10 and a decimal would be 0.4.
Step-by-step explanation:
You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)
Answer:
RANGE=21
Step-by-step explanation:
Least to greatest is KEY!
Answer:
The maximum will be 78
Step-by-step explanation:
Using the Law of Sines (sina/A=sinb/B=sincC for any triangle)
sinc/28=sin90/53 (sin90=1) multiply both sides by 28
sinc=28/53 take the inverse of sin (arcsin) of both sides
c=arcsin(28/53)°
c≈31.89° (to nearest hundredth of a degree)
So it is obvious that they rounded to nearest tenth of a degree
c≈31.9°
