An object cools at a rate of 4f per minute. its initial temperature is 10f what is the temperature of the object after 3 minutes

The final temperature is -2f.

Step-by-step explanation:

An object cools at a rate of 4f per minute. Its initial temperature is 10f. What is the temperature of the object after 3 minutes?

The final temperature will be represented by y.

y = 10f - (3 * 4f)

3 * 4f = 12f

y = 10f - (12f)

10f - 12f = -2f

y = -2f

The final temperature is -2f.

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.
