What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please

yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

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

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Write a proportion:

$\dfrac{278.2}{x}=\dfrac{19.6}{1}$

Cross multiply:

$19.6\cdot x=278.2\cdot 1\\ \\19.6x=278.2\\ \\x=\dfrac{278.2}{19/6}\approx 14\ miles$

Solve the proportion below.

melamori03 [73]

Cross multiply

19(x) = 30(9.5)

Simplify

19x = 285

Divide 19 from both sides

19x/19 = 285/19

x = 285/19

x = 15

B. 15 is your answer

hope this helps

Vinvika [58]

The volume of a cylinder is pi*height*radius^2 = pi*5*(14/2)^2 = 769.69 ft^3. To get the total gallons multiply 769.69 ft^3 by 7.5gal/ft^3 to get 5772.6765 gallons or 5773 gallons rounded to nearest whole number.
