Answer:
The length of minor arc AB is
π ft
Step-by-step explanation:
The formula of the length of an arc in a circle is L =
× 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle
∵ The radius of the circle is 4 ft
∴ r = 4
∵ ∠AOB is a central angle subtended by minor arc AB
∵ m∠AOB = 50°
∴ α = 50°
Substitute the values of r and α in the rule above
∵ L =
× 2π(4)
∴ L =
π
∴ The length of minor arc AB is
π ft
Answer:
(c) For p = 15,
leaves a remainder of -2 when divided by (x-3).
Step-by-step explanation:
Here, The dividend expression is
= E(x)
The Divisor = (x-3)
Remainder = -2
Now, by <u>REMAINDER THEOREM</u>:
Dividend = (Divisor x Quotient) + Remainder
If ( x -3 ) divides the given polynomial with a remainder -2.
⇒ x = 3 is a solution of given polynomial E(x) - (-2) =
= S(x)
Now, S(3) = 0
⇒
or, p =1 5
Hence, for p = 15,
leaves a remainder of -2 when divided by (x-3).
