Answer:
f(-3) =16
Step-by-step explanation:
f(x) = -5x + 1
f(-3) means let x=-3
Substituting x=-3 into the equation
f(-3) = -5 (-3) +1
Multiplying -5 and -3
f(-3) = 15+1
f(-3) =16
0.15 is bigger, cause the second digit after the decimal is bigger. You would have to add another 0.025 to 0.125 to bring it up to 0.15
the second one
Step-by-step explanation:
Answer: Radius = 10 cm and Arc length = 5 cm
Step-by-step explanation:
The area of a sector with radius r and central angle
(In radian) is given by :-

Given : A sector of a circle has area
and central angle 0.5 radians.
Let r be the radius , then we have

Thus, radius = 10 cm
The length of arc is given by :-

Hence, the length of the arc = 5 cm
