Answer:
The measure of the length is 
Step-by-step explanation:
Let
x-----> the length of rectangle
y-----> the width of rectangle
we know that
The perimeter of rectangle is equal to
so
Simplify
-----> equation A
----> equation B
Substitute equation B in equation A and solve for y
Find the value of x
Answer:
i think its f(x)=-2(x-2)(by the power of 2)-2
Step-by-step explanation:
No, there can not be negative amplitude because it is just the distance between the max and the midline or the minimum and the midline.
I see where you might be confused because for instance in the trig equation:
y = -3 sin (.5(x-
/2)) -1, there is a negative in front of the amplitude. However, when finding the amplitude, you take the absolute value of a.
Answer:
A=27 cm^2
B=24 cm^2
C=26 cm^2
D=28 cm^2
Step-by-step explanation:
Break each problem down into individual shapes.
For instance, A can be split into a 3 by 3 square and a 6 by 3 square.
Get the area by multiplying the length & height: A = L * H
For the triangles the area is the same equation divided by 2 A=LH/2
Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.
