Answer 5

yeah u are right!!

Answer 6

thankssss im gunna have more problems, can you help pleaseee

Answer 7

\(\bf B(t) = 50\cdot e^{2.5t}\qquad 1000\ count\implies 1000= 50\cdot e^{2.5t}\\ \quad \\
\cfrac{1000}{50} = e^{2.5t}\implies 20 = e^{2.5t}\\ \quad \\
\textit{recall the log cancellation rule of }\quad log_aa^x = x\\ \quad \\
20 = e^{2.5t} \implies log_e(20) = log_e(e^{2.5t})\implies log_e(20) = 2.5t\)

Answer 8

and I gather you can get it from there, just solve for "t"

Answer 9

16^x=64
is the answer not 3/2?

Answer 10

3/2 rounded to the nearsest decimal place is 1.5
right??

Answer 11

yeah that is right

Answer 12

3.2958 rounded to two decimal places is 3.30, right??

Answer 13

@atlas

Answer 14

absolutely

Answer 15

x≈2.0794
= 2.18? or 2.08?

Answer 16

how can it be 2.18??

Answer 17

idk.. the 7 makes the 0 into a 1 and then the 9 makes the 7 a 8
is it 2.08 ?
rounded to two decimal places?

Answer 18

@atlas

Answer 19

?

Answer 20

No it is not like that............we would have increased 0 to 1 if we wanted to eliminate 7

Answer 21

huh?

Answer 22

since we want two decimals......we don't want to eliminate 7..........we want to eliminate digits after 7

Answer 23

so 2.08

Answer 24

so we look at the digit after 7..........it is 9>5
so we increment 7 to 8

Answer 25

yup

Answer 26

@atlas

Answer 27

what do you think?

Answer 28

B?

Answer 29

Answer 30

cross multiplied

Answer 31

how do you do it? im on number 27 out of 54.. and its due in less than an hourr

Answer 32

when there is a division.........sign you invert and multiply

Answer 33

ohhh i got it

Answer 34

An hour is a lot of time

Answer 35

im slow.. no solution?

Answer 36

or is the answer 64?? @atlas

Answer 37

This is the same as what you did earlier..............16^x =64

Answer 38

The answer is 16^(3/2)

Answer 39

which =64
?

Answer 40

yeah
