What statement provides an example of designing a solution in the technological design process?
a. aerospace engineers need a lightweight material to build a jet.
b. engineers determine which features the material must-have.
c. engineers test a carbon-plastic compound in a wind tunnel.
d. the carbon-plastic compound is redesigned to save maximum energy.

B "Engineers determine which features the material must have"

Step-by-step explanation:

its b

i took the test

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.
