Option A is correct.

If we evaluate the function at x=0, i.e. at the beginning, we have

f(0)=75 \cdot 2^0 = 75 \cdot 1 = 75

with each minute, you multiply the current number of cell by 2, so they double every minute.

Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be

f(x) = 75 + 2k

Option C is incorrect, because after one minute (i.e. when x=1) we have

f(1) = 75\cdot 2^1 = 75 \cdot 2 = 150

cells, so 75 is not the number of cells after one minute

Option D is incorrect in both the initial value and the behaviour of the function

Josie spent 4/7 of ten money in her purse on some books, and the rest of the money on 18 markers. Each marker cost $1.20. How mu
NeTakaya

Let's assume money in Josie's purse to begin with as 'x'

There are 18 markers

Each marker cost $1.20

so, we can find total cost of markers

Total cost of markers = ( total number of markers)*(price of each marker)

so, we can plug value

Total cost of markers is

=18\times 1.20

=21.6$

now, we are given

Josie spent 4/7 of the money in her purse on some books

the rest of the money on 18 markers

so, rest money is

=x-\frac{4}{7} x

=\frac{3}{7} x

and this rest money is total cost of markers

so, we can set them equal and then we can solve for x

\frac{3}{7} x=21.6

7\cdot \frac{3}{7}x=21.6\cdot \:7

3x=151.2

x=50.4

So, total money in Josie's purse in beginning is $50.4..........Answer

Find the perimeter of rectangle A
Arlecino [84]

Answer:

The perimeter of rectangle A is 8x+6y or 2(4x+3y)

Step-by-step explanation:

The perimeter of a figure is the sum of its boundary dimensions.

The perimeter of rectangle A is:

4x+4x+3y+3y=8x+6y

Factorizing,

8x+6y=2(4x+3y)

How would you solve this equation? It uses logarithms.
slega [8]
\bf log_{{  a}}\left( x^{{  b}} \right)\implies {{  b}}\cdot  log_{{  a}}(x)\\\\&#10;-----------------------------\\\\&#10;2^{x+1}=5^{2x-1}\implies log(2^{x+1})=log(5^{2x-1})&#10;\\\\\\&#10;(x+1)log(2)=(2x-1)log(5)\implies (x+1)\cfrac{log(2)}{log(5)}=(2x-1)&#10;\\\\\\&#10;now\quad \cfrac{log(2)}{log(5)}\textit{ is just a constant about }0.43068

and you can simply solve that for "x"
