Answer:
1, 6.2 and 7/2
Step-by-step explanation:
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:

Where,
are parallel sides and
is the vertical distance between the parallel sides.
Putting
in the above formula, we get




Therefore, the area of the trapezium is 408 square cm.
I think the answer is
domain : (- infinity , infinity )
range : [ -2 , infinity )
i am sorry if my answer was wrong
The Lagrangian is

It has critical points where the first order derivatives vanish:



From the first two equations we get

Then

At these critical points, we have
(maximum)
(minimum)
Answer: C $1.51
To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.
You will have:
82.4/130.7 = 0.95/x
Cross multiply to solve and you will get the price of the juice is $1.51.
