Answer:
An easy way to do this problem is to follow PEMDAS if you don't know what that is it is P=() E I forgot M=Mutliply D=Division A=addition S=Sabtraction
But to do this problem first do the problem in the (3/2. 1/4) I hope this helps please reward brainlist.
X objects in t seconds.....how long to sort 15 objects....so x = 15
t = 0.007(15^2) + 0.003(15)
t = 0.007(225) + 0.045
t = 1.575 + 0.045
t = 1.62 seconds <===
Answer:
R=0.39789 ft
Step-by-step explanation:
For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower's width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:
2πR=2.5
⇒R=2.5/2π
R=0.39789 ft
The circumference of the circle is equal to
C = 2πr, where r is the radius of the circle.
Substituting r = 1, the circumference is equal to
C = 2π
Since the arc ab is π/3, its fraction of the circumference is equal to
Fraction = π/3 ÷ 2π
Fraction = 1/6
