Find all zeros of <br>f(x)= x^3 + 3x^2 − 3x − 1

PSYCHO15rus [73]

F(1) = 1^3 + 3(1)^1 - 3 - 1 = 1 + 3 - 3 - 1 = 0

so one zero is x = 1, and x-1 is a factor

dividing f(x) by x - 1 gives x^2 + 4x + 1

x = [-4 +/- sqrt (16 - 4)] / 2

x = -0.27, -3.73

zeroes are 1 , -0.27 and -3.73 Answer

The selling price of an apartment dropped from 250,000 to 225,000. By What percent did the price drop?

ch4aika [34]

Answer:

10%

Step-by-step explanation:

The percentage decrease in price = $\frac{decrease amount}{original amount}$ x 100%

Original amount = 250,000

New amount = 225,000

Decrease in amount = 250,000 - 225,000

= 25,000

So that;

Percentage decrease in price = $\frac{25000}{250000}$ x 100%

= 0.1 x 100%

Percentage decrease in price = 10%

The price of the apartment dropped by 10% of its original price.
