Answer:
h=2
a=4
k= -21
Step-by-step explanation:
your h and k are vertex . h= x coordinate of vertex and k= y
so formula for vertex coordinates is x= -b/2a and y= (4ac-b²)/4a
your a b c are 4 -16 and -5 respectively according to the main equation
your a is concavity which is the same number as the 'a' of the equation
Answer:
Applied the definition and the limit.
They had the same result, so the function is continuous.
Step-by-step explanation:
At function f(x) is continuous at x = a if:
In this question:
At x = 3.
Since 
, f(x) is continuous at x = 3.
Hey there,
I believe but I'm not quite sure, I believe that the correct answer would be 42 because by subtracting 79-37, that should give you y.
Hope this helps. (forgive any errors.)

Answer:
2
Step-by-step explanation:
Use pythagorus's theorem:
a²=b²+c²
13²=9²+x²
169=81+x²
x²=88
x=
x=
x=
x=2
Alot of equations
x+1=26
x=3+22
x^2=625
x/2=12.5
4x=100
etc
