An alternating current. I Amperes, is given by i = 10sin2nft. where f is the frequenct in Hertz and t the time in seconds. What is the rate of change of current when t = 20ms given that f = 150 Hzπ​

y = x + 95

y = 42 + 95

y=137 mm hg

2,600 divided by 80 = 32.5

step-by-step explanation:

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.
