(2, 7) and (-6, -2) find the distance between each pair of points
yaroslaw [1]

Answer:

\sqrt{145}

Step-by-step explanation:

Hi there!

We are given the points (2, 7) and (-6, -2). We want to find the distance between them. To do that, we can use the distance formula

The distance formula is given as \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, where (x_1, y_1) and (x_2, y_2) are points

We have 2 points, which is what we need to find the distance, but let's label their values to avoid any confusion

x_1=2\\y_1=7\\x_2=-6\\y_2=-2

Now substitute those values into the formula:

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\sqrt{(-6-2)^2+(-2-7)^2}

Simplify the values under the radical:

\sqrt{(-8)^2+(-9)^2}

Raise to the second power:

\sqrt{64+81}

Add the numbers under the radical together

\sqrt{145}

The answer can be left as that, as the radical cannot be simplified.

Hope this helps!

Suppose $24,000 is deposited into an account paying 7.25% interest, which is compoundedcontinuouslyHow much money will be in the
ozzi
Answer:

$49560

Explanations:

The amount deposited is the principal

The principal, P = $24,000

Interest rate, r = 7.25% = 7.25/100 = 0.0725

Time, t = 10 years

Since the interest is compounded continuously, the amounte^ formula is given as:

A\text{ = P}\times\text{e}^{rt}

Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:

\begin{gathered} A\text{ = 24000}\times e^{0.0725(10)} \\ A\text{ = 24000}\times e^{0.725} \\ A\text{ = }24000\text{ }\times\text{ }2.065 \\ A\text{ = }49560 \end{gathered}

$49560 will be in the account after 10 years if no withdrawal or deposit is made

tekilochka [14]

Answer:

the probability is 38,46%

Step-by-step explanation:

If all decks are put together and shuffled , then card is picked at random regardless of the number, then the probability that the card is red is

probability = number of red cards / total number of cards = 5/(5+2+6) = 5/13=0.3846= 38,46%
