Question

Please help! Finding Distance : Find the distance from A to C.

12

74

Square root of 74

6

Answer 1

I think it should be the square root of 74. Am I correct?

Answer 2

Gives me "Bad request" :(

Answer 3

GOt it!

Answer 4

cool

Answer 5

what are the coordinates for point A and C ?

Answer 6

i already got to 7^2 + 5^2 - c^2

Answer 7

74= c^2

Answer 8

Way 1: Distance formula \[\huge\color{blue}{ d=\sqrt{(y_1-y_2)^2+(x_1-x_2)^2} }\] plug in your points

A (-2,4)
C (3,-3)

Way 2:
draw a right triangle, Drawing point B that would be (-2,-3) and using the Pythagorean a^2+b^2=c^2

Answer 9

i just dont know what to do next

Answer 10

square both sides 74 and c^2

Answer 11

notice the coordinates for point A and C, thus \(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
A&({\color{red}{ -2}}\quad ,&{\color{blue}{ 4}})\quad &({\color{red}{ 3}}\quad ,&{\color{blue}{ -3}})
\end{array}\qquad
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)
