Convert the radian measure to degree measure. use the value of π found on a calculator, and round answers to two decimal places.

Rina8888 [55]

For converting radian to degree we simply place pi as 180 degree.

So the given angle in radians = $\frac{-19 \pi}{6}$

Now can place pi = 180 degree in this angle.

So angle in degree = $\frac{-19 * 180}{6} = -19 * 30 = -570$

So given angle in degree = -570 degree

Meg has saved up $350 to purchase a new TV from the local store. The sales tax in her county is 5% of the sticker price. Write a

Sergio [31]

For this case we have:

Let p be the highest price of the TV that Meg can buy

We have to:

5% of p is given by:

$0.05p$

So, we have:

$p + 0.05p = 350$

Clearing p we have:

$1.05p = 350$

$p=\frac{350}{1.05}\\p=333.33$

Thus, the highest price of the television that Meg purchases should be $p = 333.33$ dollars.

Answer:

$p + 0.05p = 350\\p = 333.33$

Given A(2,0) and B(8,4), show that P(3,5) is on the perpendicular bisector of line AB by these 2 methods

Shalnov [3]

1) First we need to find midpoint M of segment AB.

... M = (A+B)/2 = ((2+8)/2, (0+4)/2) = (5, 2)

Then vector AB is B-A = (8-2, 4-0) = (6, 4)

and vector PM is P-M = (3-5, 5-2) = (-2, 3)

The latter has slope that is 3/-2 = -3/2. The former has slope that is 4/6 = 2/3.

The product of these slopes is -1, indicating these vectors are perpendicular.

2) Vector PA is P-A = (3-2, 5-0) = (1, 5).

Vector PB is P-B = (3-8, 5-4) = (-5, 1).

The lengths of both of these vectors are √(1²+5²) = √26.
