Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.
h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.
h(-8) = -2[9] + 4, multiply -2 and 9.
h(-8) = [-18] + 4, add -18 and 4.
h(-8) = -14.
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
