19/2 = 9.5. Hope this helped.
The first answer is correct, if you go back by 5% each year you will see that.
It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²

a.
FALSE. Because f(4.9) will round down to
4.
b.
TRUE. c. no it's not the absolute value function. that has V-shape
d.
TRUE.
e. FALSE. because for every unique x-value you don't always get a unique y value. .... f(5)=5, f(5.1)=5, f(5.76)=5, etc.</span>
