Answer: Dismissed - Wiki
Step-by-step explanation:
Answer:
yes they are similar
Step-by-step explanation:
1/4 they are booth acute
2/4 they both have 3 faces
3/4 they both have a angle with a degrees of 41
4/4 they look alike.
there are for explanations for the similarity.
Answer:
±10i
Step-by-step explanation:
sqrt( -100)
sqrt( 100*-1 )
We know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(100)sqrt(-1)
We know that sqrt(-1) = i
±10i
The pyramid's formula for Volume is identical to the formula for Volume of a prism, except for having a factor 1/3.
Base Area and height being the same for a pyramid and a prism, the volume of the pyramid is always one third that of the prism.
A similiar fact pertains to Cone vs Cylinder...these 3 dimensional volumes have a ratio of 1/3 to one another.
In two dimensions, there's a ratio of 1/2 between areas of triangles and rectangles having the same base & height.
Given the basis β={(1,−1,3),(−3,4,9),(2,−2,4)}β={(1,−1,3),(−3,4,9),(2,−2,4)} and x=(8,−9,6)x=(8,−9,6), I am to find the corresponding coordinate vector [x]β[x]β. I claim that the coordinate vectors entries x1,x2,x3x1,x2,x3 meet the following criterion:
x1(1,−1,3)+x2(−3,4,9)+x3(2,−2,4)=(8,−9,6)x1(1,−1,3)+x2(−3,4,9)+x3(2,−2,4)=(8,−9,6)This is equivalent to solving the augmented matrix
⎡⎣⎢1−13−3492−248−96⎤⎦⎥[1−328−14−2−93946]which is row equivalent to
⎡⎣⎢100−31020−18−10⎤⎦⎥
