Do the given vectors form an orthogonal basis for ℝ3? v1 = 1 0 −1 , v2 = 2 4 2 , v3 = 3 −3 3 Yes, the given set does form an orthogonal basis for ℝ3. No, the given set does not form an orthogonal basis for ℝ3. You are given the theorem below. Let {v1, v2, , vk} be an orthogonal basis for a subspace W of ℝn and let w be any vector in W. Then the unique scalars c1, , ck such that w = c1v1 + + ckvk are given by ci = w · vi vi · vi for i = 1, , k. Use the theorem to express w as a linear combination of the above basis vectors. Give the coordinate vector [w]basis B of w with respect to the basis basis B = {v1, v2, v3} of ℝ3. w = 1 1 1 [w]basis B =

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
