Find the distance between the pair of points. Round your answer to the nearest hundredth. (-8,19) and (3,5)

Amiraneli [1.4K]

Answer:

<h3>The answer is 17.80 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8,19) and (3,5)

The distance between them is

$d = \sqrt{ ({ - 8 - 3})^{2} + ({1 9 - 5})^{2} } \\ = \sqrt{( { - 11})^{2} + {14}^{2} } \\ = \sqrt{121 + 196} \\ = \sqrt{317} \: \: \: \: \: \: \: \: \: \: \: \: \\ = 17.804493...$

We have the final answer as

<h3>17.80 units to the nearest hundredth</h3>

Hope this helps you

Remove the parentheses from the expression (–2) – (–3). A. 2 – 3 B. –2 + 3 C. 2 + 3 D. –2 – 3

lukranit [14]

Answer:

Step-by-step explanation:

The negative of a negative is a positive, so B is your choice. Think of it anothe way, if it helps. Imagine that the expression is this:

(-2) + (-1)(-3) since every subtraction problem can be rewritten as an addition problem.

We would first, by orders of operation, multiply the -1 and the -3 getting 3. Then the problem would simplify down to -2 + 3

Just another idea to ponder...

Describe how you would use the rules of exponents to simplify (7x?yz) 3. You may indicate an exponent in your answer with ^. For

SVETLANKA909090 [29]

Answer:

343x^6y^3z^3

Step-by-step explanation:

One of the rules of exponents demands:

$(abc)^m=a^mb^mc^m$

where a, b, c and m are coefficients.

Furthermore, you use the following rule for exponents of variables that already have an exponent:

$(a^n)^m=a^{m*n}$

Thus, you can apply this rules in the following way:

$(7x^2yz)^3=(7)^3(x^2)^3(y)^3(z)^3=7*7*7x^{2*3}y^3z^3=343x^6y^3z^3$

hence, the answer is 343x^6y^3z^3
