Answer:
v=5
Step-by-step explanation:
you are trying to make 4v into v right ?
so simply divide it by 4 - the same if it was 4a or 7a or 9k, always start by dividing by the number
then you need to balance the two sides - so whatever number you divide the letter by (which is the 4 in this case) , you do the same with the other side , so whatever number is after the equal sign , divide it by 4
PART ONE ↓ 4v = 20
DIVIDE BY 4 → v = 20
PART TWO v = 20 ↓
v = 5 ← DIVIDE BY 4
The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
4/8 + 3/8 = 7/8
or 1/2+3/8=7/8
0.5+0.375=0.875
Step-by-step explanation:
The angle where the shadow ends is
The distance from the tree to the angle of end shadow equal (60-20)=40ft
So the tall of tree is
Answer: No, the given transformation T is NOT a linear transformation.
Step-by-step explanation: We are given to determine whether the following transformation T : R² --> R² is a linear transformation or not :
We know that
a transformation T from a vector space U to vector space V is a linear transformation if for ∈U and a, b ∈ R
So, for (x, y), (x', y') ∈ R², and a, b ∈ R, we have
and
Therefore, we get
Thus, the given transformation T is NOT a linear transformation.
