We can find the diameter of the circle by replacing some values in the formula for circumference. The formula for find the circumference is pi * d, where pi could equal 3.14 or 22/7 and d is the diameter. After dividing pi from both sides (I used 3.14), we have the total of about 21.01, which would be our diameter. We add 4 more feet into it, resulting in 25.01 feet, and we just multiply that by $0.45 to get the total price.
We get around $11.25 as our total price.
First. distribute and multiply the the 4 to the 3^2 and the -5
so then it becomes 21+ 36 - 20
second. add and subtract that
answer is: 37

Step-by-step explanation:
Answer:
x < -1.8
Step-by-step explanation:
First, subtract 2.4 from each side, you will get 3x > -5.4
Second, divide by 3 on both sides, this will make the > turn into <.
Finally you will end up with x < -1.8.

Answer:
Step-by-step explanation:
cot²(3x)=y
y²-3y+2=0
y²-y-2y+2=0
y(y-1)-2(y-1)=0
(y-1)(y-2)=0
y=1,y=2
cot3x=1
tan 3x=1=tan (π/4)=tan (nπ+π/4)
3x=nπ+π/4=(4nπ+π)/4=(4n+1)π/4
x=(4nπ+1)π/12,n is an integer.
cot 3x=2
tan 3x=1/2
3x=tan^{-1}(1/2)≈26.57°+360n
x≈8.86°+120n
