Find the distance between A (2,6) and N (5, 10). Round<br> To the nearest tenth

Svetllana [295]

Answer:

5.0 units

Step-by-step explanation:

The distance between two points can be expressed in formula of:

$\displaystyle{d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}}$

Determine:

$\displaystyle{(x_2,y_2)}$ is (5,10).
$\displaystyle{(x_1,y_1)}$ is (2,6).

Therefore, substitute in the formula to find distance:

$\displaystyle{d = \sqrt{\left(5-2\right)^2+\left(10-6\right)^2}}\\\\\displaystyle{d = \sqrt{3^2+4^2}}\\\\\displaystyle{d = \sqrt{9+16}}\\\\\displaystyle{d = \sqrt{25}}\\\\\displaystyle{d = 5}$

Therefore, the distance between two points is 5.0 units.

When a principal amount, P, is invested at an annual interest rate, r, and compounded n times per

GaryK [48]

Answer:

n =2

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

The money is compounded every 6 months.

n is the number of times that interest is compounded per year.

Each 6 months means 12/6 = twice a year. So n =2..

How to solve -2(1-7n)-5n=34

OLEGan [10]

-2(1-7n)-5n=34

Multiply the bracket by -2

(-2)(1)=-2

(-2)(-7n)=14n

-2+14n-5n=34

-2+9n=34

Move -2 to the other side. Sign changes from -2 to +2.

-2+2+9n=34+2

9n=34+2

9n=36

Divide by 9 for both sides

9n/9=36/9

n=4

Answer: n=4
