I think that it is B because I'm pretty sure it has to be log of 50,000. But I forgot how to get the rest of it but B is the only one with log of 50k.

Find the roots of the following polynomial equations: 1. y = 2x2 + 3x - 5

nydimaria [60]

Answer:

Step-by-step explanation:

$y=2x^2+3x+5\\$

Using the quadratic formula:

$\frac{-3+-\sqrt{9-4(2)(5)}}{2(2)} = \frac{-3+-\sqrt{-31}}{4}$

Since the discriminant is negative, -31, there are no real roots

A square piece of paper has an area of 36 square inches what is the perimeter of the paper

Gekata [30.6K]

Lets represent the side of the square as s , since we know the area is 36. write s

${s}^{2} = 36$

$s = \sqrt{36}$

the square root of 36 is 6. So, we know the side is 6. The formula for perimeter is P= s+s+s+s , but since it is a square and all the sides are equal, for a perimeter of a square you can do p= 4s , now substitute 6 for s to get 4(6)=24 so the perimeter of a square would be 24 inches
