Answer:

The axis of symmetry at x= 3asdfsdf

Step-by-step explanation:

the axis of symmetry of h(x) = -2x^2 + 12x -3

To find axis of symmetry we apply formula

x= \frac{-b}{2a}

Given equation is in the form of ax^2 + bx+c

a= -2 and b= 12

Plug in the values in the formula

x= \frac{-b}{2a}= \frac{-(12)}{2(-2)=3}

The axis of symmetry at x= 3

The profit that a vendor makes per day by selling x elephant ears is given by the function P(x)= -0.004x^2+3.2x-200. Find the nu
dezoksy [38]

Answer:

The number of elephant ears that must be sold to maximize profit is 400.

Step-by-step explanation:

Given that,

The profit that a vendor makes per day is given by

P(x)= - 0.004x² +3.2 x -200

where x is number of elephant ears.

P(x)= - 0.004x² +3.2 x -200

Differentiating with respect to x

P'(x)= - 0.008x+3.2

Again differentiating with respect to x

P''(x) = -0.008

For maximum or minimum P'(x)=0

- 0.008x+3.2=0

⇒0.008x=3.2

\Rightarrow x=\frac{3.2}{0.008}

⇒ x = 400

P''(x)|_{x=400} = -0.008

Since at x=400, P''(x)<0, the profit is maximize.

P(400) = -0.004×400²+3.2×400-200

          =440

The number of elephant ears that must be sold to maximize profit is 400.

vic and ben's ages are in the ratio of 3:4. if vic is 12 years old and 3 months old how old is ben in years and months??
posledela
Converting their ages to months:
12*12=144months + 3 months
=147 months
Now, 3 is equivalent to 147 months;
4 will be equivalent to;
4*147/3
= 196 months
= 16 years and 4 months
