Answer:
Step-by-step explanation:
radius 70/2=35 cm
circumference=2πr=2π×35=70π cm
time taken to complete one revolution=0.8 s
or distance covered in 0.8 s=70π
distance covered in 1 s=70π/0.8=700 π/8=175 π/2 s=87.5 π≈274.9 cm
speed=274.9 cm/s=2.749 m/s
Remember you can do anything to an equation as long as you do it to both sides
x+9=18-2x
add 2x to both sides
2x+x+9=18+2x-2x
3x+9=18+0
3x+9=18
minus 9 both sides
3x+9-9=18-9
3x+0=9
3x=9
divide both sides by 3
(3x)/3=9/3
(3/3)x=3
1x=3
x=3
Answer:
g(2)=1
Step-by-step explanation:
We need to use the second definition of the function since x=2
g(2) = 2^3 -9(2)^2 +27(2) -25
= 8-9(4) +54 -25
= 8-36+54-25
= 1
