Answer:
48ft^2
Step-by-step explanation:
volume= length x width x height
8 x 3 x 2 = 48
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
a. By the fundamental theorem of calculus, the velocity function is
The particle starts at rest, so 
, and we have
Then the position function is
with 
, so
b. The particle is at rest whenever 
; this happens for
where 
is any integer.
Answer:
x=2
Step-by-step explanation:
2x=4
x=4/2
x=2
10x2= 20
20x3.14= 62.8
the circumference of the disc is 62.8
