For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on
Luba_88 [7]

Answer:

18 N

Step-by-step explanation:

Let <em>F</em> denote the force, <em>m</em> denote the mass of the object and <em>a </em>denote the acceleration of the object.

<em />F=ma<em />

m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg

F_{2} =ma_{2}=9*2=18N

Determine the coordinates of the vertices of the rectangle to compute the area of the rectangle using the distance formula (roun
belka [17]

Answer:

The graph of the rectangle missing in the question is shown in the figure attached.

Coordinates of the points are:

A(1,8)

B(4,5)

C(14,21)

D(17,18)

The area of the rectangle is AB*BD.

The length of a segment given two points (x1, y1) and (x2, y2) is computed as follows:

√[(y2 - y1)^2 + (x2 - x1)^2]

For segment AB:

√[(5 - 8)^2 + (4 - 1)^2] = √18

For segment BD:

√[(18 - 5)^2 + (17- 4)^2] = √338  

Then, the area is:

AB*BD = (√18)*(√338) = √(18*338) = √6084 = 78

Find the zeros of the function y=x^2-1
scoundrel [369]

Answer: 1, -1

Step-by-step explanation: This is a difference of squares when factored,

(x+1)(x-1)

Let's check using FOIL(First, outside, inside, last)

x * x =x^2

1 *x =x

x * (-1) =-x

1* -1 =-1

so x^2 +x -x -1

=x^2 -1
