Answer:
(-1, -1), (0, 0)
Step-by-step explanation:
Assuming your function is the negative cube root of negative x, the two points listed above are on the curve. (The negatives cancel, so the function reduces to f(x) = ∛x.)
The various points relative to the curve are shown in the attachment.
Answer:
the answer to this is x=16.1
Answer with Step-by-step explanation:
We are given that
u+ v and u-v are orthogonal
We have to prove that u and v must have the same length.
When two vector a and b are orthogonal then

By using the property

We know that



Magnitude is always positive
When power of base on both sides are equal then base will be equal
Therefore,

Hence, the length of vectors u and v must have the same length.
1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side
