For the table, we can count the circles that appear in each step of the fractal. The center is a single circle and is step 0. Step 1 sees 4 circles grow off of that one circle. Step 2 sees 4 circles grow off of each of these circles. Therefore the table should be:

Step 0 : 1 circle
Step 1 : 4 circles
Step 2 : 16 circles
Step 3:  64 circles

Using this table, we can solve the second part. This function is exponential growth and each step is a multiple of 4. Therefore, the function is f(x) = 4^x.

What is the value of 4x^2+5x when x=1
erastovalidia [21]
So the answer to this equation is 9
to find the answer we first need to substitute the x for 1
so the equation would be 4×1^2+5*1
so now we simplify the equation so it would be 4+5×1
and 4+5*1 simplified is 4+5
and 4+5=9

A prior study estimated as 34%. The analysts would like to conduct a second study on the same topic with a margin of error, E, o
Volgvan
The minimum sample size required for a test with a confidence interval of 100(1 - \alpha )% with a z-score of z_{ \alpha /2} and margin of error of E and a population proportion of p is given by:

n= \frac{p(1-p)z_{ \alpha /2}^2 \alpha }{E^2}

Given p = 34% = 0.34, E = 0.027, z_{ \alpha /2}=1.645

Therefore, 

n= \frac{0.34(1-0.34)(1.645)^2}{0.027^2}  \\  \\ = \frac{0.34(0.66)(2.706025)}{0.000729} = \frac{0.60723201}{0.000729}  \\  \\ =832.97=833
