The expression $-2\vec C+6\vec D$ in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is $a \vec i+b \vec j$ .

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression $-2\vec C+6\vec D$ = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16) in the ordered pair notation.

That is, the vector $\bold {-2\vec C+6\vec D}$ is a vector with x-component 16 and y-component -16.

Please help quick! V=?

Stells [14]

Answer:

904.78

Step-by-step explanation:

we have the radius, which is 6.

were trying to find the volume.

the foemula for the v of a sphere is 4/3(pi)r^3

so, multiply 4/3 times pi and we get 4.18879.

find 6^3, which is 216. multiply tyese two values, and we get 904.77864.

so, the volume of this sphere is around 904.78
