We know that the equation for Diameter is r^2(2*r), thus:
12/2=6
Your radius is 6.
A=
r^2 (pi*r^2)
Thus, your area is 113.1
Quadratic function ( in standard form ):
y = a x² + b x + c
x = 0:
635 = 0 + 0 + c
c = 635
x = 1:
644 = a + b + 635
a + b = 9
x = 2:
719 = 4 a + 2 b + 635
4 a + 2 b = 84
and now we have a system:
a + b = 9 / * ( - 2 )
4 a + 2 b = 84
-------------------------
- 2 a + 2 b = - 18
+
4 a + 2 b = 84
-------------------------
2 a = 66
a = 33; b = - 24;
Function is:
f ( x ) = 33 x² - 24 x + 635
f ( 8 ) = 33 * 64 - 24 * 8 + 635 = 2,112 - 192 + 635 = 2,555
Answer: The number of waterfowl on week 8 would be 2,555.
Hi, Ptaverez1! :)
First we must length of an individual square; This can be achieved by using the formula for the area of a square:
Lets input the information we already know:
Take square root.
The length of an individual square tile is
6.5 ft.
Since they're are 9 tiles and the porch in a square, I can conclude that the measurements for the porch are 3 tiles by 3 tiles (as 3*3=9; using the formula for the area of a square.)
Since the length of the porch is 3 tiles, we must multiply the individual tiles piece length by 3:
The formula for the perimeter of a square is:
Lets input the information we know:
The perimeter of the porch is 78 feet²
Hope this helps.

Answer: (66/11)^3-6*8 = 168
10/7+28-51/2 = 23.93
Step-by-step explanation:
<u>First set:</u>
(66/11)^3-6*8
(66/11)=6
(6)3-6*8
6^3=216
216-6*8
6*8=48
216-48= 168
<u>Second Set:</u>
10/7+28-51/2
= 206/7-5.5
= 23.928571
we would want to round that answer to 23.93
optional answers:
24
23.9
23.929
etc.
There's your answer
correct me if I'm wrong, or if this wasn't what you were looking for
Good Luck!
Edit:
the exponent is the number 3 also for the 1 question and for the 2 question the 10 and the 7 the a fraction and the 1 and two is a fraction
