(1) V = ? F = 10 U = 1 1/v + 1/u = 1/f 1/v + 1 = 1/10 10 + 10v = v 9v = -10 V = 1.111 cm. making it a concave mirror (since v cannot be negative). (2) magnification = image distance / object distance Magnification = 1 / 1.11111 magnifacation = 9 / 10
M = 615g = 0.615kg R = 123cm = 0.123m V = 5.60 ms^-1 Tension = m * v / r 0.615 / 0.123 * 5.60 = 28 Nm^-1

Its A
X=t^2, y =t - 2, t =square røot of x. Y + 2 =t . Y + 2 =square root of x . But since u want it to be lyk dis ax +by = 2. . Y - square root of x = -2

Distance = 115 miles Time taken = 5 hrs Let jacqueline average speed be = a and miranda average speed = a + 9 Jacqueline a.s + miranda a.s = 2a + 9 from, Average speed * time = distance 5(2a + 9) = 115 10a + 45 = 115 10a = 115 - 45 10a = 70 Divide both
[(8.3 + x) / 11.2] * 8 = 16 Multiply both sides by 11.2 8(8.3 + x) = 179.2 66.4 + 8x = 179.2 collect like terms 8x = 179.2 - 66.4 8x = 112.8 Divide both sides by 8 X = 14.1
Universal set = 300 Biol only = 200 - x Chem only = 150 - x Biol nd chem = x Biol nd chem = 200 - x + x + 150 - x = 300 Biol nd chem = - x + 350 = 300 Collect like terms Biol nd chem = 350 - 300 = x X = 50 (Chem U biol)' = chem only + physics only + chem
Tan x = 62ft / 22ft Tan x = 2.818 X = tan^-1 2.818 X = 70.5 review your textbook to help you draw the diagram
