-6 And 8 ok it make me have 20 c
Provided that the triangle looks like this:
A| \ | \ | \ | \ | \ b| \ 20 | \ | \ | \ | \ |_______40\C a B
Then using the the equation to solve for line segment AC (or b on the diagram):
sin(40) = b/20
b = 20 * sin 40
b = segment AC = 12.9 units
Answer:
$1125
Step-by-step explanation:
you can see on the y graph that the highest point it reaches is more than 1100 dollars so it is $1125.
First find the volume of the pipe:
V = 3.14*length*(outsideradius^2 - innerradius^2)
= 3.14 * 10*(2.5^2 - 2^2)
= 70.65 cm^3
Now find the mass using the formula density = mass / volume:
Mass = volume * density
= 70.65 cm^3 * 0.92g/cm^3
= 65 grams
The correct answer among the choices listed is option A. To calculate an object's mechanical energy, you have to add its kinetic and potential energies. Mechanical energy of an object can be the result of its motion and its stored energy therefore the total energy should be the sum of both type of energies.
