Answer:

4 and -4

Step-by-step explanation:

This is because:

1. When fractions are raised to a negative exponent, the number will become a whole number, therefore, 1/4 and -1/4 does not work.

2. -8 does not work because when you square 8 it is 64 and not 16.

3. And finally, that leaves us with two options which 4 and -4 which both work because 4^-2 = 1/16 and -4^-2 = 1/16.

Therefore, the answer is 4 and -4.

Hope this helps! :D

A community bird-watching society makes and sells simple bird feeders to raise money for its conservation activities. The materi

Answer:

N(x) = 40 - 2x

P(x) = -2x² + 52 x - 240

maximum profit = 13

Step-by-step explanation:

given data

feeder cost = $6

average sell = 20 per week

price = $10 each

solution

we consider here price per feeder = x

and profit per feeder id here formula = x - 6

so that here

total profit will be

P (x) = ( x - 6 ) Nx

here N(x) is number of feeders sold at price = x

so formula for N (x) is here

N(x) = 20 - 2 ( x - 10 )

N(x) = 40 - 2x

so that

P(x) = (x-6) ( 40 - 2x)

P(x) = -2x² + 52 x - 240

since here

a = -2

b = 52

c = -240

a < 0

so quadratic function have maximum value of c - $\frac{b^2}{4a}$

so it will be

maximum value = -240 - $\frac{52^2}{4(-2)}$

maximum value = 98

so here maximum profit attained at

x = $\frac{-b}{2a}$

x = $\frac{-52}{2(-2)}$

x = 13

maximum profit = 13

On the rectangular coordinate system, what is the shortest distance between points (−4, 3) and (−2, −1)?

pogonyaev

Shortest Distance = $\sqrt{ (-4+2)^{2} + (3+1)^{2} }$
Shortest Distance = $\sqrt{ (-2)^{2} + (4)^{2} }$
Shortest Distance = $\sqrt{20}$
Shortest Distance = $4.47 units$
