Kat should tell Kim that It's too late to change the area of this kite because the length of the diagonals of a kite determines its area.
<h3>How to calculate the area of a kite?</h3>
In Mathematics, the area of a kite is equal to one-half the product of the length of its diagonals. Mathematically, the area of a kite can be calculated by using this formula:
A = ½ × d₁ × d₂
<u>Where:</u>
- d₁ and d₂ are the length of the diagonals of a kite.
Since Kit has already cut his sticks for the diagonals, Kat should tell him that it's too late to change the area of this kite because the length of the diagonals of a kite determines its area.

Answer:
5.83
Step-by-step explanation:
Calculator

Recall that

and so replacing

with

, you get that the second limit is 1. Meanwhile,

so the limit is 0.
Step-by-step explanation:
$21
Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x
If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21
Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21
