Factor to find all possible values for x:2x²+7X+5=0

AlexFokin [52]

Answer:

D. x = -5/2, x = -1/2

Step-by-step explanation:

2x² + 7x + 5 = 0

(2x + 5)(x + 1) = 0

2x + 5 = 0 or x + 1 = 0

2x = -5 or x = -1

x = -5/2 or x = -1/2

Anni [7]

Write z in polar form:

z = 1 + √3 i = 2 exp(i π/3)

Taking the square root gives two possible complex numbers,

√z = √2 exp(i (π/3 + 2kπ)/2)

with k = 0 and k = 1, so that

√z = √2 exp(i π/6) = √(3/2) + √(1/2) i

and

√z = √2 exp(i 7π/6) = -√(3/2) - √(1/2) i

What is the volume of this figure?

Olenka [21]

The formula for the volume of a cone is 1/3 $\pi$ r²h, where r is the radius and h is the height.

Insert the values into the equation:

1/3 $\pi$ (5)²(11) ≈ 287.979327 (use a calculator for this part)

Divide 287.979327 by $\pi$ and convert the decimal to a fraction:

91.66666666666666666666666666666666666666... = 91 2/3

The volume of the figure is 91 2/3 $\pi$ cubic units or units³.
