How you do this?? I don’t get it at allll
Sidana [21]

The values are 5i, -4, 2√2i, -16, -50i and i.

<h3>What is an imaginary number?</h3>

An imaginary number is a number that, when squared, has a negative result, and is defined by its property i² = −1 or i = √-1.

Given are numbers,

1) √-25 = √25*√-1 = 5i

2) √-2√-2 = 2i*2i = 4i² = -4

3) √-8 = √8*√-1 = 2√2i

4) (4i)² = 16*i² = -16

5) (2i)(5i)² = 2i*25i² = 50i³ = -50i

6) i²*i³*i^{4} = -1*(-i)*1 = i

Hence, The values are 5i, -4, 2√2i, -16, -50i and i.

Iodine-125 has a half-life of about 60 days. How many milligrams of a 1000 mg sample will remain after 240 days?
Tomtit [17]

240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to

\dfrac{1000}{2^4}=\dfrac{125}2=62.5\,\mathrm{mg}

after 240 days.

A rectangle has a legnth of 12 inches less than 6 times its width. If the area of the rectangle is 3744 square inches, find the
elena-14-01-66 [18.8K]

Length = 6x - 12

Width = x

Area of a rectangle:

A = length x width

3744 = (x)(6x - 12)

3744 = 6x^2 - 12x

6x^2 - 12x - 3744 = 0

Use the quadratic equation to solve for x. The two solutions end up being 26 and -24. Since length is a scalar measurement, it can only be positive. Thus, the value of x is equal to 26 inches.

Width = 26 inches

Length = 6(26) - 12 = 144 inches

Hope this helps!! :)
