The distance between points $P_1(x_1,y_1)$ and $P_2(x_2,y_2)$ can be calculated using formula

$P_1P_2=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.$

$AB=\sqrt{(-7-(-11))^2+(8-4)^2}=\sqrt{16+16}=\sqrt{32}=4\sqrt{2}\approx 5.657.$

$AC=\sqrt{(-4-(-11))^2+(4-4)^2}=\sqrt{49+0}=\sqrt{49}=7.$

$CB=\sqrt{(-7-(-4))^2+(8-4)^2}=\sqrt{9+16}=\sqrt{25}=5.$

Then

$P_{ABC}=5.657+7+5=17.657\approx 17.7$

Answer: correct choice is C.

What is a simpler form of the radical expression?<br><br> SOMEONE PLEASE HELP!!

Brilliant_brown [7]

Answer:

Choice B

Step-by-step explanation:

Given radical expression:

$\sqrt[4]{1296 {x}^{16} {y}^{12} }$

To Find:

The Simpler form of this expression

Soln:

$= \sqrt[4]{1296 {x}^{16} {y}^{12} }$

We could re-write the given expression, according to the law of exponents:

$= \tt \sqrt[4]{(6x {}^{4}y {}^{3}) {}^{4} }$

Now we need to bring terms out of the radical as:

$\tt = | 6x { }^{4} y {}^{3} |$

Bring out 6x^4 from the absolute & put y^3 only in it:

$\tt = 6x {}^{4} |y {}^{3} |$

Choice B is accurate.

When you buy an item on which sales tax is charged,the total cost is calculated by the formula T=P+s/100p where T is the total c

Gennadij [26K]

Given:

The formula for total cost is

$T=p+\dfrac{s}{100}p$

where, p is the price of item and s is the sales tax rate (as a percent).

You pay $14.77 for an item priced at $14.

To find:

The the tax rate.

Solution:

You pay $14.77 for an item priced at $14. So,

Total cost (T) = $14.77

Price of item (p) = $14

Putting T=14.77 and p=14 in given formula, we get

$14.77=14+\dfrac{s}{100}(14)$

$14.77-14=\dfrac{s}{100}(14)$

$0.77=\dfrac{s}{100}(14)$

Multiply both sides by 100.

$77=14s$

Divide both sides by 14.

$\dfrac{77}{14}=s$

$5.5=s$

Therefore, the tax rate is 5.5%.

Answer:

|x-5|=2

Step-by-step explanation:

1- Find the mid value between the given numbers 3 and 7

(3+7)/2= 10/2 = 5

2- Find the difference btween the mid value (5) and any of the two given numbers (3 or 7). Use the absolute value for the difference.

|5-3|= 2 or |7-5|=2

3- Arrange the absolute equation like this:

|x-mid value from step 1|= absolute difference from step 2

|x-5|=2

4- Double check the answer with the given values 3 and 7 using our equation |x-5|=2

|3-5|=2 correct

|7-5|=2 correct
