first most important effect is the erosion and the second most important effect is weathering.
Answer:
the volume of a cone = 1589.625feet³
Step-by-step explanation:
given that the diameter of the cone = 15inches
radius = 15inches/2 = 7.5inches
height of the cone = 27 inches
volume of the cone = ?
recall that
the formulae for finding the volume of a cone is given to be
= 1/3πr²h
the volume of a cone = πr² h/3
the volume of a cone = 3.14 × ( 7.5)² × 27/3
the volume of a cone = (3.14 x 56.25 x27)/3
the volume of a cone = 4768.875/3
the volume of a cone = 1589.625feet³
When you write that equation, you get 3x^2+6=81.
Solving for x:
Subtract by 6 on both sides of the equation to get 3x^2=75.
Then, divide by 3 on both sides of the equation to get x^2=25.
Finally, do the square root on both sides of the equation to get x=5.
The number is 5.
Answer:
5x + 6y = -10
Step-by-step explanation:
(-2, 0) and (-8, 5)
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - 0) / (-8 -(-2)
m = 5 / (-8+2)
m = -5/6
y = mx + b
(-8, 5)
5 = -5/6(-8) + b
5 = 40/6 + b
b = 5 - 40/6
b = -5/3
y = mx + b
y = -5/6x - 5/3 *6
6y = -5x -5(2)
6y = -5x - 10
5x + 6y = -10
