Find the magnitude of v. v = -3i+ 40 + 7k v =
kherson [118]

Answer:

The magnitude of the given vector is 40.72 units.

Step-by-step explanation:

The given vector is v=-3\widehat{i}+40\widehat{j}+7\widehat{k}

We know that for any vector 'r' \overrightarrow{r}=x\widehat{i}+y\widehat{j}+z\widehat{k} the magnitude is given by

|r|=\sqrt{x^{2}+y^{2}+z^{2}}

Comparing with the given vector we have

x = -3

y = 40

z = 7

Thus the magnitude equals  

|v|=\sqrt{(-3)^{2}+40^{2}+7^{2}}

|v|=40.72

PLEAASE HELP
gladu [14]
Well you are given the equation so let's plug in for kaylib and see how many miles she can see
distance = sqrt [(3 * height) / 2]
d = sqrt [(3 *48) / 2]
d = sqrt (144 / 2)
d = sqrt (72)
d = sqrt (3 * 3 * 2 * 2 * 2)
d = 6 * sqrt (2)

You you did not list Addisons height but I will say she is at x feet above sea level. we plug in x for height:
d = sqrt [(3x) / 2]

It it says how much farther for Addison which means she can see farther. to find difference we just subtract kaylibs distance from Addison. so:
sqrt [(3x) / 2] - 6 * sqrt (2)

plug in your x and use a calculator to get a decimal approximation
