Answer:
1) C=2355 2) C=1570 3) C=157 4) C=40.82
Step-by-step explanation:
We use formula to find the Circumference of circle is :
i) C=(PI)d ii) C=2(PI)r
1. d=750 m
C=(PI)d = (3.14)(750)=2355
2. d=500 kg
C=(PI)d=(3.14)(500)=1570
3. r=25 cm
C=2(PI)r
=2(3.14)25=157
4. r=6.5 m
C=2(PI)r
=2(3.14)(6.5)
=40.82
5x^3+40x^2-100x
5x(x^2+8x-20)
=5x(x+10)(x-2)
......... what even is the question?????
Okay so you do 6r-8r which = -2r
Then you do 5t-4t which = 1t
So the answer simplified = -2r + 1t
y= -6x -9
slope stays the same because it is parallel and the y intercept ends up being -9 for the new equation
