Jadual 1 menunjukkan enam pasangan bacaan bagi pemboleh ubah $x$ dan $y$ yang dicatatkan dalam suatu eksperimen. Apabila $xy$ diplot melawan $x^2$, kesemua enam titik yang diperoleh terletak pada satu garis lurus.
x 1 2 3 4 5 6
y 8.5 8.0 9.5 11.5 13.7 16.0
Dengan menggunakan garis lurus itu, ungkapkan $y$ dalam sebutan $x$, seterusnya cari nilai $y$ apabila $x = 2.828$. Beri jawapan betul kepada tiga angka bererti.English
Table 1 shows six pairs of readings of the variables $x$ and $y$ recorded during an experiment. When $xy$ is plotted against $x^2$, all six points obtained lie on one straight line.
x 1 2 3 4 5 6
y 8.5 8.0 9.5 11.5 13.7 16.0
Using this straight line, express $y$ in terms of $x$, and hence find the value of $y$ when $x = 2.828$. Give your answer correct to three significant figures.Tap to take a photo or choose an image
