The answer is.

The Lamp post is 800cm

x = height of lamp post

160/90 = x/450

450 is the length from the base of the lamp post to the end of the shadow (360+90)

cross multiple

90x = 72000

x =800cm

Have a great day!

Use the discriminant to determine all values of k which would result in the graph of
Shalnov [3]

Answer:

k > 100

Step-by-step explanation:

y= x²+20x+k

if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots

discriminant is

b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400

k > 100 is the solution

Sketch the graph y=-csc1/2x over a two interval period
sp2606 [1]
Well, the negative rotates it around x. Then the 1/2 stretches it. Csc(x) has a period of 2pi. So now it has a period of 4pi. If you want a double check: http://www.wolframalpha.com/input/?i=y%3D-csc%28%281%2F2%29x%29
