Point D is the midpoint of the outer circle that we aim to find the area of
The circle has a diameter of WZ and radii of WC and CZ
We know that YZ=YD=10 cm
Let DC be
and CY be
The radius of the outer circle can be written as
or
which we can equate to find the value of
Therefore, the radius of the circle is
And hence the area of the circle is
=324
Answer:
A right triangle
Step-by-step explanation:
(a)
We can see that
this is a straight line
and this is the graph of velocity
we know that
acceleration is the derivative of velocity
so, slope of curve of velocity is acceleration
so, we will find slope of this line
We can select any two points
(0,4) and (5,7)
we can use slope formula
now, we can plug points
we know that slope of line is always constant irrespective of any value of t
so, acceleration will always be same irrespective of any value of t
so, we will get acceleration
............Answer
(b)
we can see that acceleration is constant
and we know that
derivative of constant is always 0
so, instantaneous rate of acceleration at t=10s is 0........Answer

Step-by-step explanation:
3 divided by 45.6 =15.2
Answer:
x =10
Step-by-step explanation:
7(3x-1)-(x+5)
21x-7-x+5
20x-2=-52
x=20÷2
