Plz now really important : ) 2. the following formula relates three quantities: force (f), mass (m), and acceleration (a). f = ma a. solve this equation for a. b. if the force is f = –25 units and the mass is m = 10 units, find the acceleration, a. c. if the force is f = 25 units and the acceleration is a = 5 units, find the mass, m.

2. F = ma

a.) Solve this equation for a (isolate the a)

F = ma     Divide m on both sides

b.) F = -25

m = 10

a = ?

a = -2.5

c.) F = 25

a = 5

m = ?

F = ma

25 = m(5)   Divide 5 on both sides

5 = m

(don't forget the units, because I forgot to put the units)

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
