Answer:
it's simple
Step-by-step explanation:
r=d/2
r=12/2
r=6
circumference of circle = 2πr
=2*(3.14)*6
=12*3.14
= 37.68
Answer:
x = 12
Step-by-step explanation:
10 – 7x = 2 – 8x
– 7x + 8x = 2 + 10
x = 12
Answer:
y = (1/3)x^3 +4x + c . . . . . for some constant c
Step-by-step explanation:
The anti-derivative of x^n is (x^(n+1))/(n+1). Applying this rule to each of the terms in dy/dx, we get ...
y = (1/3)x^3 + 4x
There may be an added constant as well, conventionally represented by "c".
y = (1/3)x^3 +4x +c
Answer:
x = -3, y =3
Step-by-step explanation:
y = -4/3x - 1
y = 1/3x + 4 -------> 4y = 4/3x + 16
Adding the first equation and the new second equation together:
5y = 15 ------> y = 3
Plug y = 3 into one of the original equations:
3 = 1/3x + 4
-1 = 1/3x
x = -3
