Z4=289 there should be 4 answers total 2 whole numbers and either 2square root or imaginary number answers

There are 4 solutions and they are:

where i = sqrt(-1) and also "sqrt" is shorthand for "square root"

Work Shown:

Let x = z^2. Square both sides to get x^2 = (z^2)^2 = z^(2*2) = z^4

In short, x^2 = z^4, so we can replace the 'z^4' with 'x^2' to get this new equation x^2 = 289

Apply the square root to both sides

x^2 = 289

sqrt(x^2) = sqrt(289)

sqrt(x^2) = sqrt(17^2)

|x| = 17

x = 17 or x = -17

For each equation above, replace x with z^2 and solve that equation for z

x = 17

z^2 = 17

sqrt(z^2) = sqrt(17)

|z| = sqrt(17)

z = sqrt(17) or z = -sqrt(17)

which are two solutions out of the four total

The other two solutions are found by plugging x = z^2 into x = -17 and solving for z

x = -17

z^2 = -17

sqrt(z^2) = sqrt(-17)

|z| = sqrt(-1*17)

|z| = sqrt(-1)*sqrt(17)

|z| = i*sqrt(17)

z = i*sqrt(17) or z = -i*sqrt(17)

which are the other two solutions

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
