Answer:
x (5/2 , 0)
y (0, -5)
Step-by-step explanation:
I believe
Substitute b for given values
64 = 100 - 6r
16 = 100 - 6r
Move too to other side
-36 = -6r
-84 = -6r
Divide each side by 6
6 = r
14 = r
are your answers.
Option A is correct.
If we evaluate the function at , i.e. at the beginning, we have
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
Option C is incorrect, because after one minute (i.e. when x=1) we have
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
52
Step by Step
Let the unknown number be X
X(.75) = 39
Divide both sides
39 divided by .75 is 52
X = 52
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
