Timed*** there are 8 rows and 8 columns, or 64 squares on a chessboard. suppose you place 1 penny on row 1 column a, 2 pennies on row 1 column b, 4 pennies on row 1 column c, and so on … how many pennies are on each square? a =   b =   c = d =   e =   f = g =   h =

In the first row, A = 1, B = 2, C = 4, D = 8, E = 16, F= 32, G = 64, H = 128

Step-by-step explanation:

We are given the beginning of the sequence:  1, 2, 4, ...

We can see that each time, the number of pennies is doubled to find the next number.  This means the next ones would be 4(2) = 8; 8(2) = 16; 16(2) = 32; 32(2) = 64; 64(2) = 128

if you need just tell me and i will come to the rescue.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
