If <br> (x — 2)2 + (y — 3)2 (z + 4) = 0 what is the value of x + y + z? A) —4 B) 0 C) 1 D) 2

Aleksandr [31]

Answer:

1

Explanation:

(x-2)^2 = x equals 2 ( double roots)

(y-3)^2 = y equals 3 (double roots)

(z+4)^2 = -4 (double roots)

2 + 3 -4 =1

Evaluate the line integral, where c is the given curve. C (x/y) ds, c: x = t3, y = t4, 1 ≤ t ≤ 4.

skelet666 [1.2K]

We have

x = t³ ===> dx/dt = 3t²

y = t⁴ ===> dy/dt = 4t³

Then with the given parameteriztion, the line integral along C of x/y is

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{t^3}{t^4} \sqrt{(3t^2)^2 + (4t^3)^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac1t \sqrt{9t^4 + 16t^6} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{\sqrt{t^4}}t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{t^2}t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \int_1^4 32t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \int_1^4 \sqrt{9 + 16t^2} \, d\left(9+16t^2\right)$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \cdot \frac23 \left(9+16t^2\right)^{\frac32}\bigg|_1^4$

$\displaystyle \int_C \frac xy \, ds = \frac1{48} \left(265^{\frac32} - 25^{\frac32}\right) = \boxed{\frac{265\sqrt{265}-125}{48}}$

Given the equation representing a reaction: h + h h2 what occurs during this reaction?

tangare [24]

A bond is formed, and energy is released.

Explanation:

This is because energy is absorbed when a bond is broken. So, when these to Hydrogen combines a bond is formed and the energy is released,

Also, for a bond to be in broken energy, the energy is absorbed but when the bond is going to be formed, the energy is released instead.

one key to success in a career is to be an accomplished a]procrastinator b] problem solver c]antagonist d]hypocrite apex

ohaa [14]

The answer would be B)Problem solver.

Explanation:

-Procrastinating isn't a way to having a successful career. It's not good to wait to the last moment. At the last moment your mind turns into mush and you get scared because, you haven't gotten someting done and it needs to be handed in

-Problem solving is your career is the best way to go. Being able to solve problems while in distress is the best way to go. Solving stuff on your own can make you more successful, and you can improve on misakes you've made in the past.

-Antagonist is one of the worse ways to go. You can't have a successful career if your being hostile.

-Hypocrite apex is the worst by far way to go. You can't make it long in a career if your a hypocrite. They can't be successful because, there not doing any good.
