Answer:
PERIMETER=Y+2Y+11+-3Y-9+Y^2+5Y-1+6Y^2
=7Y^2+4Y+1
Answer:
.

Step-by-step explanation:
From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable (
in this case) so that images exist and the range of a function is the set of images.
In this case, we know the domain and range of
and we must find the domain and range of
.
Domain
The domain of
is the domain of
. That is,
.
Range
We have to define the bounds of the range of
, given that range
is modified by streching and horizontal translation operations:
Lower bound (
)

Upper bound (
)

In consequence, the range of
is 
Answer:
3rd one
Step-by-step explanation:
Answer:
1 . 24
2. 21
Step-by-step explanation:
1.
b=6
h=4
A= b*h
=6*4
=24
2. b=6
h= 7
A= 1/2*b*h
= 1/2*6*7
=21
Answer:
Step-by-step explanation:
Average rate of change is the same thing as the slope. Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function. But we can use the same idea. When t = 3, h(t) = 33, so the coordinate point is (3, 33). When t = 6, h(t) = 0, so the coordinate is (6, 0). Plug those values into the slope formula:
and
which is -11
