What is the square root of 28x to the third power y to the third power

Colt1911 [192]

Hello!

√28x³y³ is equal to $2xy\sqrt{7xy}$

We can find this solution through the following steps.

Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²
We then can rewrite 4 as 2² in our equation, leaving us with $\sqrt{2^{2}*7*(x^{2}x)*y^{2}y }$
We will then move our x and 7, and rewrite $2^{2}*x^{2}* y^{2}$ as $(2xy)^{2}$
We can then pull the terms from the radical leaving us with $2xy\sqrt{7xy}$

If an object takes 7 second to fall to the ground, what was its initial height? Show your work.

Verdich [7]

Answer:240.1 m

Step-by-step explanation:

We are given the following equation that models the the time it takes to an object to fall to the ground:

$t_{(H)}=\sqrt{\frac{2H}{g}}$

Where:

$t_{(H)}=7 s$ is the time it takes to the object to fall to the ground

$H$ is the object's initial height

$g=9.8 m/s^{2}$ is the acceleration due gravity

Isolating $H$ :

$t^{2}=(\sqrt{\frac{2H}{g}})^{2}$

$t^{2}=\frac{2H}{g}}$

$H=\frac{t^{2}g}{2}$

Solving with the given data:

$H=\frac{(7 s)^{2}(9.8 m/s^{2})}{2}$

$H=240.1 m$ This is the initial height

How to find if an equation is parallel perpendicular or neither?

iren [92.7K]

Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:

Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
