Answer:
[tex] \frac{354 \times 6789}{98 \times - 4} = - −6,130.8827
Resolving horizontally . Make forces to the right positive
resultant force = 70cos30-60cos60 = 60.62-60 = 0.62 lbs
resolve vertically
resultant force = 120 sin60 - 70 sin30 = 103.92 - 35 = 68.92 lbs in downward direction
magnitude of the ressultant forsse = sqrt(68.92^2 + 0.62^2) = 68.92 lbs
direction of the force = tan-1 (0.62 / 68.82) = 0.52 degrees east of south or
a bearing of
90 - 0.52 = 89.48 degrees
Answer:
D
Step-by-step explanation:
First find the probability using the normal distirbution formula X - mean / standard deviation for both X = 350 and X =450 to get the values -1 and 1 so thi(-1) < P(Z) < thi(1) if you are familiar with normal distirbution table values you will calculate that the overall probability is 0.6827
knowing this we can roughly expect how much emergencies are in the response times by 0.6827 x 144 = 98
(fg)(x) = (x^3 -4x+2)(x^2+2)
(fg)(x) = x^5 - 4x^3 + 2x^2 + 2x^3 -8x + 4
(fg)(x) =x^5 - 2x^3 + 2x^2 -8x + 4
answer
x^5 - 2x^3 + 2x^2 -8x + 4
