I need help with this question. The directions say to evaluate and express the answer in the simplest form.

Step-by-step explanation:

(9)^-5/2

In order to get rid of the negative exponent, take the reprocal of 9/1

⇒()^5/2

⇒This is also the same thing but we’re are breaking it down.

⇒We are further breaking this down...

^ is technically the square root of a number.

=1

=243

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
