C=2πr
C=πd
A=πr^2
r=C/2π
r=1/2 d
<u>By the way all you do to solve r is: </u>
C=2πr
C/2π=2πr/2π
C/2π=r
r=C/2π
Hope this helps:)
Answer:
4/3
Step-by-step explanation:
To the power of negative one just means 1 divided by and 1 divided by 3/4 is just 4/3
The slope: 3/5
Y-intercept:-6
#1) 9=6 - 3 |4p + 9| now we're going to distribute
9= 6 - 12p - 27
9= 6 - 27 - 12p
9= - 21 - 12p
9 + 21= -12p
30= - 12p Now you are going to divide both side by -12
-12:30 = -12:-12p
-5/2= p final answer
#2) - |1 + 4a| = -13 now you going to change the sign
-1 - 4a = -13
-4a = -13 + 1
-4a = -12 now divide both side by -4
-4a:-4 = -12:-4
a = 3 final answer
Answer:
a(n)=60-30n
Step-by-step explanation:
Equation to use:
a(n) = a(1) + d(n-1)
where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.
In this case, a(1) is 30, d is -30, and n is just n.
If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.
Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.
