Answer:
a fixed sum of money paid to someone each year, typically for the rest of their life.
Answer:
135°
Step-by-step explanation:
∠AOB = ∠COB = 90°
∠BOK = 45°
90 + 45 = 135°
Answer:
40 square units
Step-by-step explanation:
A = LW
A = 5 units x 8 units
A = 40 square units
Answer:
-2 and 24
Step-by-step explanation:
the trend line is linear,
let the unknowns be A and B
hence the equation becomes
K = AJ + B
from the graph we can see the following:
when J = 0, K = 24 (substitute this into the equation)
K = AJ + B
24 = A(0) + B
24 = B (Answer)
Also notice that when K = 0, J = 12
together with our previous finding that B = 24, the equation becomes:
K = AJ + B
0 = A(12) + 24
12A = -24
A = -24 / 12
A = -2 (answer)
Answer:
[8i + 54j + 72k] joules per newton metre square.
Step-by-step explanation:
F(x,y,z) = z2i + 3xyj + 3y2k
F(3,0,0) = 0
F(3,3,1) = 1(2i) + 3(3)(3)j + 3(3)(2k)
= 2i + 27j + 18k
F(0,3,1) = 1(2i) + 3(0)(3)j + 3(3)(2k)
= 2i + 18k
The sum = [4i + 27j + 36k]
Since the particle moves back to the origin, we multiply the above Work Done by 2:
[8i + 54j + 72k]
And since work done is the product of Force and Distance, the S.I. unit is Joules/newton metre square
