b. 104 km
c. 317 km
d. 213 km
i think this one is d

when gottfried is at cruising altitude, his speed is 225 km/hr. approximately how much time does he spend at cruising altitude? (remember that speed is equal to distance divided by time, and pay close attention to the units.)

it's the only multiple of both and the least

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.
