Suppose you have the formula =$d$5*e5 in cell f5. when you copy the formula into cell f6 what will the new formula be?

a. =$d$5*e5

b. =d5*e6

c. =$d$5*e6

d. =$d$6*e6

C. =$D$5*E6

Step-by-step explanation:

In excel Columns are A, B, C, D,

And, rows are, 1, 2, 3,

Also, the intersection of column and row is called cell,

eg : A1 is a cell,

When we copy a function formula from a cell A1 to B2,

Then in the formula we replace A1 by B2 or vice versa,

But the row or column which comes after the dollar sign is anchored or absolute.

That is, when we copy an excel formula with $ sign they will copy cells referred in that formula relative to the position where they are being copied to.

Thus, if we have the formula =$D$5*E5 in cell F5,

Then, $D$5*E6 must be the new formula into cell 6.

Option 'C' is correct.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
