We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
Answer:
the answer is C
Step-by-step explanation:
Let's see what to do buddy...
_________________________________
The sum of the angles of each n-sided figure is found in the following equation :

The question's figure is 5-sindes figure
so the sum the angles equal :

So we have :


Subtract the sides of the equation minus 479


And we're done.
Thanks for watching buddy good luck.

Area of the circle:
π(r²)=π(14)²=196π
=615.75216
Area not covered by the sprinkler:
784-615.75216=168.24784 m²
