Answer:
Volume, 
Step-by-step explanation:
It is given that,
Diameter of spherical boulder is 18 ft
Weight of spherical boulder is 8 tons.
We need to find the volume of spherical boulder. The formula of the volume of sphere is given by :
r is radius of spherical boulder, r = 9 ft
Substituting all values in above formula :
The volume of spherical boulder is 
.
Hope this helps you out :D
It’s 2 equations so in order to solve the previous system, you can use different methods, as for example substitution or addition of equations. In this case, you use the second one, due to the fact you have 7x in one equation and -7x in the other equation. In this way you can easily eliminate variable x and then solve for y. With the value of y you can replace in any of the two equations and solve for x.
7x-y=-1
-7x+3y=-25
Summarizing, you proceed as follow:
- add up the given equations
7x - y = -1
-7x+3y=-25
——————
0 +2y=-26
- solve for y in the previous equation
2y=-26
y=-26/2
y=-13
- replace the obtained value of y in one of the given equations, and solve for x
7x-(-13)=-1
7x+13=-1
7x=-1-13
7x=-14
x=-14
x=-14/7
x=-2
Hence, the solution of the given systems of equation is:
X=-2
Y=-13
Answer:
The domain of the given function is
{x | x= -4,-1, 3, 5, 6}
The answer to your question is: 60.3°
Data
height = 7 m
shadow = 4 m
angle = ?
Process
tangent Ф = opposite side / adjacent side
tangent Ф = 7 / 4
tan Ф = 1.75
Ф = 60.3°
