Answer 0.06*0.7+0.03=0.072 and 0.06*(-0.2)+0.03=0.018
Insert x = -1 and y = 4 into the first inequality:-
4 <= -(-1) + 4 = 5
so this fits
Its A
Answer:
4.4N, 263.4°
Step-by-step explanation:
The sum of all forces must add to zero:
The forces in the x-plane:
∑F = 3N + (cos 120°)*5N + x = 0
x = -(3N + (cos 120°)*5N)
x = -0.5N
The forces in the y-plane:
∑F = (sin 120°)*5N + y = 0
y = -(sin 120°)*5N = -√(3/4)*5N = -4.3N
The magnitude of the unknown force U is:
U = √(x² + y²) = √19 = 4.4N
The direction is given by:
tanФ = y/x
Ф = 263.4°
Answer: a= 187.5 m squared
Step-by-step explanation: a=ab/2
we know that
The value of the tangent is equal to
remember that
substitute
therefore
<u>the answer is</u>
square root 3
