42 represents 35% of the total mulch he had on the truck.
Set up an equation.
42 = .35x
divide both sides by .35
x = 120 pounds
CHECK
120(.35) = 42 pounds

By definition, the arc length is given by:
s = R * theta
Where,
theta: angle
R: radio
Substituting values we have:
s = (34) * ((5/4) * π)
s = (34) * ((5/4) * (3.14))
s = 133.45 cm
Answer:
the length of an arc with a central angle of 5 / 4π radians and a radius of 34 centimeters is:
s = 133.45 cm
F(x) = x² + 4x - 1
f(x) = x² + 4x + 4 - 4 - 1
f(x) = (x + 2)² - 5
Answer:2/5 a)
