Answer:

$F_{2} = 80\,N$

Step-by-step explanation:

Given the consideration of the inverse proportionality between force and distance, the following relationship is constructed and described below:

$F_{1}\cdot r_{1}^{2} = F_{2}\cdot r_{2}^{2}$

The force when the distance is halved is:

$F_{2} = F_{1}\cdot \left(\frac{r}{0.5\cdot r} \right)^{2}$

$F_{2} = 4\cdot F_{1}$

$F_{2} = 4\cdot (20\,N)$

$F_{2} = 80\,N$

Given ,

a = 3 , b = -5 , c=6

1) a(3c-b) = 3(3(6)-(-5)) = 69

2) ab^2-ac = (3)(-5)}^2-(3)(6) = (-15)^2-18 = 225-18 = 207

7 x 7 x 7 x 7.
49 x 7 x 7
343 x 7
2,401

So 7 to the power of 4 is 2401.

Answer: b₂=2A/h-b₁

Step-by-step explanation:

A =1/2 (b₁ + b₂)h

2A=(b₁ + b₂)h

2A/h=b₁ + b₂

b₂=2A/h-b₁
