What is the approximate distance between the points (-3,-4)(-8,1) on a coordinate grid?

Alex

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-8-(-3)]^2+[1-(-4)]^2}\implies d=\sqrt{(-8+3)^2+(1+4)^2} \\\\\\ d=\sqrt{25+25}\implies d=\sqrt{50}\implies d\approx 7.071$

A right angle has an area of 13m*2. The dimensions of the triangle are increased by a scale factor of 3. What is the area of the

Alex_Xolod [135]

The answer is: 117m²

The explanation is shown below:

1. You have the following information given in the problem:

- The triangle has an area of 13 m².

- The dimensions of the triangle are increased by a scale factor of 3.

2. Therefore, to solve the exercise you must multiply the area by $3^{2}=9$ , as following:

$A=(13m^{2})(9)\\A=117m^{2}$

Answer:

Speedy Taxis

Step-by-step explanation:

I solved this by using a graphing calculator. Speedy Taxis shows the least cost for x=30.

__

You can figure the cost of each for x=30

1.5(30) = 45

1.1(30)+11.5 = 33+11.5 = 44.5 . . . . . lowest cost

1.25(30)+8 = 37.5+8 = 45.5

Speedy Taxis is the cheapest for a trip of 30 miles.
