Answer:
Yi Xing invented the astronomical clock and introduced some new methods of interpolation in mathematics.
Step-by-step explanation:
Yi Xing was both an astronomer and a mathematician during the era. He invented the astronomical clock which was more accurate than the initial water and Sun's clock in use.
Furthermore, Yi Xing also discovered some new methods of interpolation in mathematics of which the meaning and interpretation became controversial. Interpolation is a method majorly in mathematics that can be used to estimate a value of a function from its discrete values. It involves first order differences and second order differences.
Also, Yi Xing was able to design a calendar in A.D. 727.
F(4)=2(4)^3-5(4)^2-11(4)-4=128-80-44-4=0
Solution is 4
Answer:I think not certain.it will be 300+100+40+70+1+2
Answer:
x = 5 ± sqrt(35)
Step-by-step explanation:
X^2 - 10x+ 25 = 35.
Factor the left hand side. This is the difference of squares. a^2 -2ab - b^2 = (a-b)^2 where a = x and b = 5
(x-5) ^2 = 35
Take the square root of each side
sqrt((x-5) ^2) =± sqrt(35)
x-5 = ± sqrt(35)
Add 5 to each side
x-5+5 = 5 ± sqrt(35)
x = 5 ± sqrt(35)
Faye has 243 beads.
She uses 51 for each necklace.
243/51 = 4.7...
243-51-51-51-51=39.
She can make 4 necklaces, with an extra of 39 beads.
