There is no difference. Both mean the same measurement except that 1.050 is presented in 4 significant figure and 1.05 in 3 significant figure.
Answer:
x=-2,y=-4
Step-by-step explanation:
By dividing to lowest terms
5x – 5y = 10= x-y=2.......(1)
6x – 4y = 4=3x-2y=2........(2)
By elimination method
Multiply equation (1) by 3 so as to correspond with equation (2)
3(x-y)=3(2)
3x-3y=6..........(3)
Multiply equation (2) by 1 so as to correspond with equation (1)
1(3x-2y)=1(2)
3x-2y=2..........(4)
Then equation (3)-equation (4)
(3x-3y=6)
-
(3x-2y=2)
__________
-y=4
y=-4
Substitute y=-4 into equation(1)
x-(-4)=2
x+4=2
x=-2
Therefore x=-2,y=-4
The formula is pi*r^2*h/3
your answer would have to be B
Answer:
p=£800
r=5%
t=3years
Step-by-step explanation:
simple interest=ptr/100=£800×5×3/100=£120
To answer, subtract x² from both sides of the equation to give us,
y² = -x² + 9
Then, we derive the equation in terms t.
2y(dy/dt) = -2x(dx/dt)
Substituting the known values from the given,
2(sqrt6)(dy/dt) = -2(-sqrt3)(20)
The value of dy/dt is 14.14.
