(-3, -2) is the vertex.
You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.
And another spot on the vertex would be (0, 16), which is the y intercept.
Answer:
Not on a coordinate plane
Step-by-step explanation:
We must use absolute value because lengths should always be positive you cannot have a negative length or distance.
Answer:
Range for third side is
(
5
,
25
) cm.
Step-by-step explanation:
As two sides of triangle are 10 and 15
,
the third side would have to be less than the sum of other two sides i.e. less than 25 cm.
On the other hand if it is smaller one than this side plus side of length 10
should be greater than 15 and therefore
this side is greater than 15
−
10
=
5 cm.
Hence range is
(
5
,
25
)
