What is the distance between 3, 5 and -4, 1

Mathematics
1 answer:
USPshnik [31]3 years ago
5 0

Answer:

Distance = 8.06

Step-by-step explanation:

We have to use the distance formula d=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}  }.

(x_{1},y_{1}) = coordinates of the first point

(x_{2},y_{2} ) = coordinates of the second point

To solve, plug the appropriate values into the formula.

d=\sqrt{(-4-3)^{2} +(1-5)^{2} } = \sqrt{65} = 8.062257748

Help me w this multiple choice!
olga2289 [7]

Answer:

D

Step-by-step explanation:

\sin(30)  =  \frac{n}{ \frac{10 \sqrt{3} }{3} }   \\ 0.5 =  \frac{n}{5.77} \\ n = 2.88 =  \frac{5 \sqrt{3} }{3}

\cos(30)  =  \frac{m}{ \frac{10 \sqrt{3} }{3} }  \\ 0.866 =  \frac{m}{5.77}  \\ m = 5

Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 + 45 - 135 + ...
nalin [4]

Answer:

<em>summation of five times negative three to the power of n from n equals zero to infinity</em>

Step-by-step explanation:

<u>Summation Notation </u>

It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:

5-15+45-135+...

If we take 5 as a common factor, we have

5(1-3+9-27+...)

The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1

The summation is then represented by

\sum_{n=0}^{\infty}5(-3)^n

This corresponds with the option:

<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
