Find the magnitude of wx for w(-3 5 4) and x(9 5 3)

Hatshy [7]

Answer: Magnitude of wx is $\sqrt{145}$

Step-by-step explanation:

Since we have given that

$w(-3,5,4)=-3\hat{i}+5\hat{j}+4\hat{k}\\\\x(9,5,3)=9\hat{i}+5\hat{j}+3\hat{k}$

Now, first we will find 'wx':

$wx=Initial-Final\\\\wx=(9+3)\hat{i}+(5-5)\hat{j}+(3-4)\hat{k}\\\\wx=12\hat{i}-1\hat{k}$

We need to find the "magnitude":

$\mid wx\mid=\sqrt{12^2+1^2}=\sqrt{144+1}=\sqrt{145}$

Hence, Magnitude of wx is $\sqrt{145}$

If Mars has a diameter of approximately 4200 miles, what is the volume of Mars.

Alex777 [14]

Answer:

Dimplified: $3.88$ × $10^{10}$ , or $38,800,000,000$

Unsimplified: $38,792,400,000$

Step-by-step explanation:

Remember, the volume of a sphere is $V=$ $\frac{4}{3}$ $\pi r^{3}$

This comes into: $3.87924$ × $10^{10}$

As we know, the shape of mars is a sphere.

Let me know if you have a question, or if it lets you not have the × $10^{10}$
