Answer:

$y^{-2}$

Step-by-step explanation:

there is a rule that says

$(x^a)^b=x^{ab}$

so in our case

$(y^{\frac{-1}{2} })^4=y^{\frac{-4}{2} }=y^{-2}$

so that's our answer

$y^{-2}$

Marat540 [252]

Answer:

Marco will need $3\ ft^{2}$ of material to make the kite

Step-by-step explanation:

we know that

To know how much material Marco will need to make the kite, the area must be calculated.

Remember that the area of the kite is equal to

$A=\frac{1}{2}[d1*d2]$

where

d1 and d2 are the diagonals of the kite

we have

$d1=2\ ft$

$d2=3\ ft$

substitute

$A=\frac{1}{2}[2*3]=3\ ft^{2}$
