Step-by-step explanation:
√(-5.5-6.5)²+(-3+3)²
=√144
=12
THR = RHR + 0.65(MHR - RHR)
For a 43 year old person, MHR = 220 - 43 = 177
THR = 54 + 0.65(177 - 54) = 54 + 0.65(123) = 54 + 79.95 = 133.95 ≈ 134.
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)
