The correct answer is:  [D]:  "  x² – 5x – 24 " .
____________________________________________________
Explanation:
_____________________________________
Given:  " (x + 3)(x – 8) " ; expand :
______________________________________
Note:  (a + b) (c + d) = ac + ad + bc + bd .
_____________________________________
a = x ; 

b = 3 ; 

c = x  

d = 8
_______________________________________

   " (x + 3)(x – 8) " ; 

        =  (x * x)  + ( -8 * x)  + ( 3 * x ) + (3 * -8) ; 

        =  x² + (-8x) + 3x + (-24) ;

         = x² – 8x + 3x – 24 ;

→ Combine the "like terms" :

          – 8x  +  3x  =  – 5x ;

And simplify the expression; 

to get: 

→  " x² – 5x – 24 " ; which is:  Answer choice:  [D]:  " x² – 5x – 24 " .

Ksivusya [100]

Answer:

Buffalo mild wings offers the lowest price per wing ($0.83).

Step-by-step explanation:  

Let us find unit price per buffalo wing of each restaurant.

\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}

\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,

\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}

Therefore, buffalo bills offers each wing for $0.88.

\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}

\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,  

\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}

Therefore, buffalo mild wings offers each wing for $0.83.

\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}

\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.

1) A projectile is thrown upward so that its distance above the ground after t seconds is
leonid [27]

Answer:

After 22 seconds the projectile reach its maximum height of 4,840 units

Step-by-step explanation:

we have

h(t)=-10t^{2}+440t

This is a vertical parabola downward (because the leading coefficient is negative)

The vertex is a maximum

Find out the coordinates of the vertex

Convert the quadratic equation in vertex form

Factor -10

h(t)=-10(t^{2}-44t)

Complete the square

h(t)=-10(t^{2}-44t+22^2)+(10)(22^2)

h(t)=-10(t^{2}-44t+22^2)+4,840

Rewrite as perfect squares

h(t)=-10(t-22)^{2}+4,840

The vertex is the point (22,4,840)

therefore

After 22 seconds the projectile reach its maximum height of 4,840 units
