Answer:
66.26 kg
Step-by-step explanation:
weight = mass x g ; where g = acceleration due to gravity = 9.81 m/s²
mass = weight ÷ g
given, weight = 650 N
mass = 650 / 9.81 = 66.26 kg
Answer:
The equation is not a function.
Step-by-step explanation:
We are given that
Function: It is mapping between the values of two sets A and B.
Each element of A has unique value in set B.
By definition of function
In given function
y has no unique value for each value of x.
Substitute x=0
Hence, it is not a function.

Answer: C) x = 13</h3>
====================================================
Work Shown:
We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.
Use the pythagorean theorem to find x.
a^2 + b^2 = c^2
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
x^2 = 169
x = sqrt(169) .... apply the square root to both sides
x = 13
<span>Lets find the volume of a cylinder with a diameter D=10 inches and lenght L= 20 inches. First we need to notice that the diameter is twice the size of the radius: D=2r. Then we write the equation for the volume of the cylinder. it is the base times the height: V=pi*r^2 * L. Now we input the nubmers in the equation: V=3.14*(D/2)^2 * L where r=D/2=5 inches and after calculating we get: V=1570 inches^3</span>
