Answer:
A) 32 kg/m
B) 48 kg/m
C) 72 kg/m
Step-by-step explanation:
We are given mass is; m = 4x²
Linear density is the derivative of mass with respect to the position x. So linear density is;
ρ = dm/dx
Differentiating 4x²,we have; ρ = 8x
A)at x = 4; ρ = 8(4) = 32 kg/m
B) at x = 6; ρ = 8(6) = 48 kg/m
C) at x = 9; ρ = 8(9) = 72 kg/m
Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
-6x+4y=-6
-8x+4y=-4
------------------
-6x+4y=-6
-(-8x+4y)=-(-4)
----------------------
-6x+4y=-6
8x-4y=4
--------------------
2x=-2
x=-2/2
x=-1
-8(-1)+4y=-4
8+4y=-4
4y=-4-8
4y=-12
y=-12/4
y=-3
Answer:
Step-by-step explanation:
Hello : let
A(5,22) B(2,13)
the slope is : (YB - YA)/(XB -XA)
(13-22)/(2-5) = -9/-3
an equation is : y=ax+b a is a slope
y = 3x +b
the line through point A (5,22) :
22 = 3(5)+b
b = 7
the equation is : y =3x+7
