What is the midpoint of ac? a. (4a, 4b) b. (2a, 2b) c. (a, b) d. (a/2, b/2)

Choice C is correct.

Step-by-step explanation:

The  formula to find mid-point of a line segment is:

M= (/2,/2)

where  () and () are end-points  of a line segment.

we have to find mid-point of AC.

A is located at the center of xy-graph.

hence, A() is given as (0,0) and C() is given as (2a,2b).

put above values in the formula of mid-point formula:

M=(0+2a/2,0+2b)

M=(2a/2,2b/2)

M=(a,b) is mid-point of AC.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
