Answer:
Step-by-step explanation:
The attached diagram shows the triangle ABC formed by the ladder with the wall of the house.
Triangle ABC is a right angle triangle. It has a 90 degree angle. The length of the ladder forms the hypotenuse(AC)of the triangle. This length can be determined by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
AC^2 = 22^2 + 5^2
AC^2 = 484 + 25 = 509
AC = √509
AC = 22.56
The slope of the ladder is
(change in y)/(change in x)
Slope = 22/5 = 4.4
Answer:
y = -3/2x + 3
Step-by-step explanation:
We can get 2 points from the graph
(0,3)
(2,0)
from (0,3) we know that the b in the equation is 3
now to calculate m or slope we use
= -3/2
so we plug our m and b into y = mx + b and get
y = -3/2x + 3
Answer:
Volume of air in the tank =1,044 Liter
Step-by-step explanation:
Given:
Tank volume = 8 Liter
Pressure = 141 atm
Temperature = 22°C = 273° + 20° = 295° K
