Y=2x2+18 find coordinates of the vertex

Step-by-step explanation:

x- coordinate of the vertex is

x= -b/2a = -0/2*2 = 0

y-coordinate is

y= 2*0 +18 = 18

so vertex is at (0, 18)

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
