Ewe’ll Love this Lawn! Charlie’s lawn covers an equilateral triangle
of side length 20 metres. He doesn’t enjoy
mowing and so he borrows 3 sheep, tying
one to a post at each corner, using ropes 10
metres long, so that they can graze the lawn
for him.
He decides to create a circular flower bed in
the centre of the lawn. What is the diameter
of the largest flower bed he could have that
is still safe from the sheep?
How much lawn will he actually need to
mow? Give your answers to 3dp.

56

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

the answer is a.
