2^(n-1) = 256 ? Please give me the answer​
klemol [59]

Answer:

n = 9

Step-by-step explanation:

Note that

256 = 2^{8}, thus

2^{n-1} = 2^{8}

Since the bases on both sides are equal (2) equate the exponents

n - 1 = 8 ( add 1 to both sides )

n = 9

Phillipa is a scientist who grows yeast cells. She starts her experiment with 700 yeast cells and notices the growth rate of the
musickatia [10]

Answer:

  1. 700 initial cells
  2. 2486 cells after 25 hours

Step-by-step explanation:

#1 There are 700 yeast cells when Phillipa starts her experiment. (This value is given in the problem statement.)

__

#2 For this, we must assume the time period that is associated with the 5.2% growth. (The problem statement does not specify it.)

The general form of the equation for exponential growth is ...

  f(t) = (initial value)×(growth multiplier in time period)^(number of periods)

When the growth (or decay) rate is indicated as a percentage (r), the "growth multiplier in time period" is generally ...

  growth multiplier = 1+r

Here, the value of "r" is 5.2% = 0.052, so the growth multiplier in the time period is ...

  1 + 0.052 = 1.052

__

As we said, the time period is not specified. Since the only time period mentioned in the problem is 25 hours, we might reasonably assume that the 5.2% growth occurs in one hour. Then the cell population is ...

  f(t) = 700×1.052^t . . . . . . for t in hours

After 25 hours, ...

  f(25) = 700×1.052^25 ≈ 700×3.55135 ≈ 2485.9 ≈ 2486

The number of yeast cells present after 25 hours is about 2486.

A rectangular pool has an area of 5x2 + 23x + 12 and the length of one side is 5x + 3. What is the
RoseWind [281]

Answer:

x + 4

Step-by-step explanation:

Area of rectangle= length × breadth

In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12

This means that;

5x2 + 23x + 12 = 5x + 3 (b)

Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3

To get the other length, we can factorize the algebraic expression;

5x2 + 23x + 12

Product: 60x^2 (20x × 3x)

Sum: +23x (20x + 3x)

Hence;

= 5x^2 + 20x + 3x + 12

Next, we find factors;

5x (x+4) + 3 (x+4)

Therefore, the factors are (5x + 3) and (x +4)

This means that the other length is (x +4)
