Given: △abc, bk=10, ac=30,
m∠nmo=90°,
mn=mo, bk⊥ac, no ∥ac, m∈ac
find: no

12 units.

Step-by-step explanation:

Consider right triangle MNO. This triangle is isosceles triangle, because MN = MO. Let NO = 2x units. NO is the hypotenuse in right triangle MNO, then MD = x units (the height in isosceles triangle is also its median and the median drawn to the hypotenuse in the right triangle is half of the hypotenuse).

Triangles NBO and ABC are similar triangles, then

where h is the height of the triangle NBO.

Since BK =10 units and MD = x units, the height h = 10 - x units.

Thus,

Hence, NO = 12 units.

x=half

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
