1) 1

2)
{4}^{ - 3}  =  \frac{1}{64}
3)
{ - 5}^{3}  =  - 125
4)
{ \frac{4}{5} }^{3}  =  \frac{64}{125}
5) 3² × 3³ = 9 x 27 = 243

6)
{7}^{5}  \div  {7}^{2}  =  {7}^{3 }  = 343
7)
( {1}^{3} )^{4}  = 1
8)
{3}^{3}  \div  {3}^{5}  =  {3}^{ - 2}  =  \frac{1}{9}

An aircraft factory manufactures airplane engines. The unit cost C (the cost in dollars to make each airplane engine) depends on
butalik [34]

Answer:

90 engines must be made to minimize the unit cost.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

f(x) = ax^{2} + bx + c

It's vertex is the point (x_{v}, y_{v})

In which

x_{v} = -\frac{b}{2a}

y_{v} = -\frac{\Delta}{4a}

Where

\Delta = b^2-4ac

If a>0, the minimum value of the function will happen for x = x_v

C(x)=x²-180x+20,482

This means that a = 1, b = -180, c = 20482

How many engines must be made to minimize the unit cost?

x value of the vertex. So

x_{v} = -\frac{b}{2a} = -\frac{-180}{2(1)} = 90

90 engines must be made to minimize the unit cost.
