**Answer:**

**Step-by-step explanation:**

**The quadratic expression in the standard form is given by :**

**f(x) = + bx + c **

**(b) To complete the square:**

**Divide the equation through by a , the equation then becomes**

**f(x)= + + **

**At this point, you are require to**

**(i) multiply the coefficient of x by 1/2**

**(ii) square the result**

**(iii) add the result to both sides , we have**

**f(x) = + + + + by completing the square , we have **

**f(x) = + - . We did this in order to make the expression balance **

**(c) Using the order of operation to turn the expression back into standard form**

**i. Expand the function in the bracket , we have**

**f(x) = + + + - **

**⇒ f(x) = + + + - **

**⇒f(x) = + + **

**multiply through by the L.C.M , which is a , then we have **

**f(x) = - bx + c .**

**Since the aim of completing the square is to make the expression a perfect square , then it will always result in a perfect square trinomial.**

Answer:

4.4 ft/s

Step-by-step explanation:

Height = 15ft

Rate= 5 ft/s

Distance from the man to the kite= 32ft

dh/dt = 5 ft/s

h = √32^2 - 15^2

h = √ 1025 - 225

h = √800

h = 28.28ft

D = √15^2 + h^2

dD/dt = 1/2(15^2 + h^2)^-1/2 (2h) dh/dt

= h(225 + h^2)^-1/2 dh/dt

= (h / √225 + h^2)5

= (28.28 / √225 + 28.28^2)5

= (28.28 / √1024.7584)5

= (28.28/32)5

= 0.88*5

= 4.4 ft/s
