Answer:

$4.39*10^{-4}\ m/sec$

Step-by-step explanation:

Remember that

$1\ m=100\ cm$

$1\ min=60\ sec$

The speed is equal to divide the distance by the time

Convert the units

$4.25\ min=4.25(60)=255\ sec$

$11.2\ cm=11.2/100=0.112\ m$

$0.112/255=0.000439\ m/sec$

$4.39*10^{-4}\ m/sec$

What is the distance between points A(-3,4) and B(1,-2)?

SashulF [63]

Answer:

7.211103

Step-by-step explanation:

For:

(X1, Y1) = (-3, 4)

(X2, Y2) = (1, -2)

Distance Equation Solution:

d=(1−(−3))2+(−2−4)2−−−−−−−−−−−−−−−−−−−√

d=(4)2+(−6)2−−−−−−−−−−√

d=16+36−−−−−−√

d=5–√2

d=7.211103

If 33% of the members of Sweetheart Union sign petitions to decertify the union, the National Labor Relations Board will call an

Elis [28]

Answer:

There is no need to call for election.

Step-by-Step Explanation

Surveys are based on probability or statistics. It serves as a standard tool for experimental research in marketing, social sciences and official data statistics.

Since 8 out of 40 members of the Sweetheart Union will sign the petition, the percentage of those who will sign the petition is calculated below:

$\frac{8}{40}*100=20\%$

Based on the sample survey, only 20 percent of the members will sign the petition. Since, in the sample, the number of those who will sign is less than 33%, the union should be told that there is no need for the National Labor Relations Board to call for the election.

$7000 is compounded semiannually at a rate of 11% for 21years Find the total amount and round to the nearest cent

photoshop1234 [79]

$\text{Given that }\$7000 \text{ is compounded semiannualy at a rate of }11\% \text{ for 21 years}\\
\\
\text{we know that the amount after t year when compounded is given by}\\
\\
A=P\left ( 1+\frac{r}{n} \right )^{nt}\\
\\
\text{here P is the principal amoount, so }P=7000,\\
\\
\text{r is the interest rate, }r=11\%=0.11\\
\\
\text{n is the number of times in a year, here semiannulay, so }n=2,\\
\\
\text{and t is the time, so }t=21\\
\\
\text{so the amount after 21 years is}$

$A=7000\left ( 1+\frac{0.11}{2} \right )^{2(21)}\\
\\
\Rightarrow A=7000\left ( 1+0.055 \right )^{42}\\
\\
\Rightarrow A=7000\left ( 1.055 \right )^{42}\\
\\
\Rightarrow A\approx 66328.68$

So the amount after 21 years is: $66328.68
