Answer:
10800
Step-by-step explanation:
The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday it was 3600. How many bacteria in the colony at 7 pm?
Step-by-step explanation:
B = B₀ Kⁿ
At 4 pm yesterday the number of bacteria is 400
B₀ = 400
n = number of hrs
at 6 pm yesterday it was 3600 => n = 6- 4 = 2 hrs
B₂ = 3600
=> 3600 = 400 * k²
=> k² = 9
=> k = 3
At 7 Pm Yesterday
n = 7-4 = 3
B₃ = 400 * 3³
=> B₃ = 27 * 400
=> B₃ = 10800
bacteria in the colony at 7 pm = 10800
or B₂ = 3600 & n = 7-6 = 1
Then B₃ = 3600 * 3¹ = 10800
And boom here
Answer:
its 2/3 < 3/4 so its B
Step-by-step explanation:
The last term is 63 so 3 might be a zero of the function;-
f(3) = 27 - 7*9 - 3*9 +63 = 27 - 63 - 27 + 63 = 0 so 3 is a zero and
therefore (x - 3) is a factor of the volume function.
Long division of the expression by x - 3 gives the quotient:-
x^2 + 4x - 21
Factoring this:-
= ( x + 7)(x - 3)
So the dimensions of the box are, x-3, x-3 and x+7 answer.
-338 is the answer or you got no cookies <3
Answer:
The most straightforward way to convert a positive power of two into the form 2n is to count the number n of divisions by 2 that it takes to reach a quotient of 1. For example, the number 524,288 requires 19 divisions to reach 1, giving 219: 524,288/2 = 262,144.Nov 14, 2008
