Step-by-step explanation:
question no . 5
ratio of angle L
take angle as reference angle
using cos rule
cos L = base / hypotenuse
= 4/5
ratio of angle N
take angle N as reference angle
using sin rule
sin N = opposite / hypotenuse
= 4/5
for measure of angle L
cos L = 4/5
cos L = 0.8
L =
L = 36.9
for meanure of angle N
sin N = 4/5
sin N = 0.8
N =
N = 53.1
Answer:
center of mass
X =
Y =
Step-by-step explanation:
y = x and x = 0
parabola ; y = 20 - x^2
attached below is the detailed solution
M = б
Mx = б
My = б
X =
Y =
You can find the volume by using the formula of density
where d is the density, m is the mass and v is the volume
You have to solve the formula for v like this:
you have the density and the mass so you just have to replace the variables in the formula with the values they are giving you, like this:
The volume of the stone is 7ml
where d is the density, m is the mass and v is the volume
You have to solve the formula for v like this:
you have the density and the mass so you just have to replace the variables in the formula with the values they are giving you, like this:
The volume of the stone is 7ml
