Answer: the graph farthest to the right is almost correct. If you substitute values for x in the function f(x)= -3√x , the output does not match the curve on the graphs shown.
If you have a choice that includes only a curve to the right of the y- axis, that would be better.
Step-by-step explanation: Square roots of Negative x-values will result in imaginary numbers. Otherwise the graph with the curve passing through coordinates (1,-3) (4,-6) and (9,-9) is a good choice.
(And ask your teacher about the square root of negative numbers on this graph.)
2/3 of 8 miles is 5 and 1/3 miles. So they walked about 5 and 1/3 miles there.
Step-by-step explanation:
Convert the fractions in the yards given to decimals, because then you can divide the length of the sidewalk by the length of each tile. So 2/5 is 2 divided by 5 which equals .4. And 1/8 is 1 divided by 8 which is .125.
So, the sidewalk is 14.4 yards long and each tile is 1.125 yards long.
Divide the length of the sidewalk, 14.4 yards, by the length of each tile, 1.125 yards.
Equals 13.8 tiles, rounded off to 14 tiles.
Hope this helps.
14 2/5 = 72/5
1 1/8 = 9/8
72/5 = 576/40 divide by 45/40 = 576/40 x 40/45 = 23040/1800 = 12.8 tiles
Distance = Square Root ( (X difference)^2<span> + (Y difference)^</span>2<span> )
</span>Distance = Square Root [(1 -9)^2 + (7 --2)^2]
Distance = Square Root (-8^2 + 9^2)
Distance = Square Root (64 + 81)
Distance = Square Root (145)
