Answer:
y² + 10y + 6x + 58 = 0
Step-by-step explanation:
Focus of the parabola has been given as (-7, -5) and directrix as x = -4
Let a point on the parabola is (x, y).
By the definition of a parabola, "distance of a point on parabola is equidistant from focus and directrix".
Distance from focus of the given point = 
Distance of the point from directrix = 
Therefore, equation of the parabola will be,
x² + 14x + 49 + y² + 10y + 25 = x² + 8x + 16
y² + 14x + 10y + 74 = 8x + 16
y² + 10y + 6x + 58 = 0
Answer:
-8 + 10 = 2
Addictive inverse of 8 is -8
Hi,
f + g is a simple sum of the functions. This refers to increasing the good effect of exercise with diet effect, therefore more weight could be lost.
(f + g)(x) = f(x) + g(x) = 2x + 210 + 2x + 125 = 4x + 335, so (f + g)(x) = 4x + 335.
For x = 3 (meaning 3 hours of exercise) we have:
(f + g)(3) = 4·3 + 335 = 12 + 335 = 347 calories, after 3 hours of exercice.
The correct answer is: 347 calories burned while combining diet with 3 hours of exercise.

Answer:
%
Step-by-step explanation:
Surface area of a human body is given by -
Taking integral on both sides, we get -
Since, the at most error in the surface area of a human body is 
%
Substituting this in above equation, we get -
![\frac{dS}{S} \leq [0.425*0.02 + 0.725*0.02]\\\frac{dS}{S} \leq0.023\\](https://tex.z-dn.net/?f=%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq%20%5B0.425%2A0.02%20%2B%200.725%2A0.02%5D%5C%5C%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq0.023%5C%5C)
Thus, the maximum error is surface area is equal to
%
