Answer:
(x+16)^2=20^2+x^2
Step-by-step explanation:
Given there was no bending of the tree, the Pitagorean Theory would help finding the value of the trees hight.
x^2+32x+16^2=400+x^2
32x=(20-16)×(20+16)
x=144/32
x=4m and 50cm

Step-by-step explanation:
The main purpose of controlling inventory is to make sure that the optimal amount of products are being kept.
Therefore, option A is correct.
Answer:
r = i + j + (-2/3)(3i - j)
Step-by-step explanation:
Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant
if a = i + j ; b = t(3i - j) and r = -i +s(j)
for this to be true all the vector components must be equal
summing i 's
i + 3ti = -i; then t = -2/3
j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3
so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j
