PLEASE HELP ME QUESTION IS AT THE BOTTOM OF THE PICTURE
ivolga24 [154]

Answer:

A 28 and 45

Step-by-step explanation:

So keep in mind that columns must add up to the total numbers, and rows must add up to their total numbers.

We know that what goes in the box canoeing + swimming is

x + 43 = 71.

It needs to add up to 71!

x = 71 - 43 = 28

We know that what goes in the box no swimming + no canoeing is

34 + y = 79

It needs to add up to 79.

y = 19 - 34 = 45

So the answer is <u>A. 28 and 45.</u>

Now, I did this with the columns, but you could easily do this with the rows and get the same result!

If $3000 is deposited in an account that pays 5% interest, what is the difference in the amount after 4 years between the amount
Triss [41]
\bf \qquad \textit{Simple Interest Earned Amount}\\\\&#10;A=P(1+rt)\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\to& \$3000\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;t=years\to &4&#10;\end{cases}&#10;\\\\\\&#10;A=3000(1+0.05\cdot 4)\implies \boxed{A=3600}\\\\&#10;-------------------------------\\\\

\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\quad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\to &\$3000\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{annually, thus once}&#10;\end{array}\to &1\\&#10;t=years\to &4&#10;\end{cases}

\bf A=3000\left(1+\frac{0.05}{1}\right)^{1\cdot 4}\implies A=3000(1.05)^4\implies \boxed{A=3646.51875}\\\\&#10;-------------------------------\\\\&#10;\stackrel{\textit{compounded interest}}{3646.51875}~~-~~\stackrel{\textit{simple interest}}{3600}

Find all polar coordinates of point p if p=1,-x/6
Alecsey [184]

Answer:

All polar coordinates of point P are; (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)

Step-by-step explanation:

The polar coordinates can be represented as;

(r,Ф)= (r,Ф+2nn) or (r,Ф) =(-r,Ф+(2n+1)n)

Where n is any integer value.

From the question, we are given that; p=(1,-x/6)

Comparing it with P(r,Ф), then r = 1 and Ф = -x/6

The polar coordinates will now be;

P(r,Ф) = (r,Ф+2nn)  = (1 , -x/6 + 2nn)

Where; n is any positive integer and the value of r is positive.

While;

P(r,Ф) =(-r,Ф+(2n+1)n) = (-1, -x/6+(2n+1)n) and n is any positive integer and the value of r is negative.

Thus, all polar coordinates of point P are  (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)
