In the following sequence, the figures are made of cubes that are glued together. If the exposed surface needs to be painted, how many squares will be painted in (a) the 15th figure? (b) the nth figure?" squares painted
a. The 15th figure will have
(Type a whole number)

1,589.63 in.^3

step-by-step explanation:

i hope this you : d

i believe the answer is c.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

the answer to this is a. a^2 + b^2 = c^2
