Answer:
- 892 lb (right)
- 653 lb (left)
Step-by-step explanation:
The weight is in equilibrium, so the net force on it is zero. If R and L represent the tensions in the Right and Left cables, respectively ...
Rcos(45°) +Lcos(75°) = 800
Rsin(45°) -Lsin(75°) = 0
Solving these equations by Cramer's Rule, we get ...
R = 800sin(75°)/(cos(75°)sin(45°) +cos(45°)sin(75°))
= 800sin(75°)/sin(120°) ≈ 892 . . . pounds
L = 800sin(45°)/sin(120°) ≈ 653 . . . pounds
The tension in the right cable is about 892 pounds; about 653 pounds in the left cable.
_____
This suggests a really simple generic solution. For angle α on the right and β on the left and weight w, the tensions (right, left) are ...
(right, left) = w/sin(α+β)×(sin(β), sin(α))
Answer:
the first one has one solution because eventually they will cross
Answer:
7/2
Step-by-step explanation:
To get the number of 1/2 cup servings in 7/4 cups of rice you need to divide 7/4 by 1/2
7/4 ÷ 1/2
7/4×2/1----------------------multiplied by the reciprocal
14/4-----------------simplify by dividing both parts by 2
7/2----------------simplest fraction form
its answer is option C ( translation and dilation)
because translation means :- in geometry when object moves in certain distance without changes
dilation means :- any object which is enlarged from its original shape
so option c
