Step-by-step explanation:

y=-4x²

if <em><u>x=0</u></em> x=2

y=0 y=16

<em><u>x=</u></em><em><u>1</u></em> x=-2

y=4×1² <u>y=-16</u>

y=4

<em><u>x</u></em><em><u>=</u></em><em><u>-1</u></em>

Rectangle ABCD translates 4 units down and 2 units to the right to form rectangle A'B'C'D'. The vertices of rectangle ABCD are l
AlekseyPX

The length of B'C' in the rectangle A'B'C'D' = 9 units.

<u>Step-by-step explanation</u>:

step 1 :

Draw a rectangle with vertices ABCD in clockwise direction.

where, AB and DC are width of the rectangle ABCD.

            AD and BC are length of the rectangle ABCD.

step 2 :

Now,

The length of the rectangle is AD = 5 units and

The width of the rectangle is AB = 3 units.

step 3 :

Draw another rectangle with vertices A'B'C'D' extended from vertices of the previous rectangle ABCD.

step 3 :

The length of the new rectangle is A'D' which is 4 units down from AD.

∴ The length of A'D' = length of AD + 4 units = 5+4 = 9 units

step 4 :

Since B'C' is also the length of the rectangle A'B'C'D', then the measure of B'C' is 9 units.

As a manager for an advertising company, you must plan a campaign designed to increase Twitter usage. A recent survey suggests t
kolbaska11 [484]
Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI) \hat{p} \pm z^{*} \sqrt{ \frac{\hat{p}(1-\hat{p})}{n} }  \\ where \\ n=sample\, size \\ z^{*}=1.645 \, at \, 90\% \, CL

We want the confidence interval to be 5% or 0.05. Therefore
0.85 - 1.645 \sqrt{ \frac{0.85(1-0.85)}{n} }=0.05 \\ 0.85 -  \frac{0.5874}{ \sqrt{n} } =0.05 \\  \frac{0.5874}{ \sqrt{n} }=0.8 \\  \sqrt{n} = .7342 \\ n=0.54

Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.

Answer: 30
