The length of the circle - <span>the product of the diameter and the number Pi
l = d</span>π
l = 900cm
π ≈ 3,1415 przyjmiemy wartość 3
900cm = d* 3 [:3
d = 300cm
<span>Becky rounded value of Pi , hence the difference in result
</span>
<span>More accurate calculation
</span>
l = d*π
900cm = d*3,1415
d = 900cm : 3,1415 = 286,49cm
<span>Becky overestimated the outcome</span>
By Green's theorem, the integral of
along
is

which is 6 times the area of
, the region with
as its boundary.
We can compute the integral by converting to polar coordinates, or simply recalling the formula for a circular sector from geometry: Given a sector with central angle
and radius
, the area
of the sector is proportional to the circle's overall area according to

so that the value of the integral is

Answer:

Step-by-step explanation:
<u>Given:</u>
- Volume of fuel = 5/6
- Volume of fuel used each time = 1/12
- Number of travels to or from work = x
<u>Since each time 1/12 of the tank is used, and initial volume is 5/6 of the tank, the equation will be:</u>
<u>Solving the equation we get:</u>
So Felitz can travel 10 times to/from work with 5/6 full tank

The advantages of writing the polynomial expression
-7
+ 32x + 240 in factored form when interpreting this
situation
Factorizing the quadratic equation gives
-7
+ 32x + 240
-7
+60x - 28x + 240
x×(-7x + 60) -4 ×(-7x + 60)
(x-4)×(-7x + 60)
The roots of the equation<em> 4,-60/7</em>
<em>Advantages of writing the polynomial expression in factored </em>
- <em> we directly know the roots </em>
- <em> we can easily draw the graph of the quadratic</em>
