Find the distance between M(-2,3) and N(8,2)

AnnZ [28]

Answer:

$d=\sqrt{101}$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(8-(-2))^2+(2-3)^2}$

$d=\sqrt{(8+2)^2+(-1)^2}$

$d=\sqrt{(10)^2+1}$

$d=\sqrt{100+1}$

$d=\sqrt{101}$

Winnie poured 14 cups of water into a rectangular container measuring 13 inches by 7 inches by 6 centimeters. [1 cup = 14.44 cub

Alex_Xolod [135]

Part A:
Max volume = Volume of container = 13 in x 7 in x 6 in = 546 in^3 

Part B: 
1 cup = 14.4375 in^3 

14 cups = 14.4375 in^3 x 7 = 202.125 in^3 

Part C: 
Height of water = (202.125 in^3)/(13 in x 7 in) = 2.22 in.
