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.

Help with math pls cant figure it out

Answer:

\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}

Step-by-step explanation:

You can solve this equation with the quadratic formula which is:

m_{1,2}=\frac{-b+or-\sqrt{b^{2}-4ac } }{2a}

All you need to do is rearrange the equation (add -\frac{11}{2} to both sides and then multiply both sides by 2) to get:

2m^2-5m+11=0

From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:

m_{1,2}=\frac{5+or-\sqrt{(-5)^{2}-4(2)(11) } }{2(2)}

That simplifies to:

\frac{5}{4}+or-\frac{\sqrt{25-88} }{4}

Which simplifies even further to:

\frac{5}{4}+or-\frac{\sqrt{-63} }{4}

Which gets you:

\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}

P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.

P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.

The side of the base of a square prism is decreasing at a rate of 7 kilometers per minute and the height of the prism is increas
Ber [7]

Answer:

dV = - 5.73*10⁹ m³/s

Step-by-step explanation:

Question: What is the rate of change of the volume of the prism at that instant (in cubic meters per second) ?

A function can be dependent on one or more variables. The change in the function due to a change in one o its variables is given by the functions derivative with respect to that variable. For functions that are composed of products of its variables, we may use the product rule to determine its derivative.

The volume of a square prism with base a and height h is given by

V = a²h

When the base and height are changing, we have

dV = 2ah(da/dt) +  a²(dh/dt)

Given

a = 4 Km

h = 9 Km

da/dt = - 7 Km/min

dh/dt = 10 Km/min

we have

dV = 2(4 Km)(9 Km)(- 7 Km/min) +  (4 Km)²(10 Km/min)

⇒   dV = - 504 Km³/min + 160 Km³/min = - 344 Km³/min

⇒   dV = - 5.73*10⁹ m³/s
