if P(x)=1+6x-5x^2 represents the profit in selling x thousand Boombotix speakers, how many speakers should be sold to maximize p

Rashid [163]

Answer:

600

Step-by-step explanation:

$p(x) = 1 + 6x - 5x^2$

x max = $-b/2a$

a = -5

b = 6

-6/2(-5) = 6/10 = 3/5 = .6

.6 thousand = 600

600 speakers should be sold.

Alternatively, you can check the vertex of the parabola formed.

The area of circle B is 121 times greater than the area of circle A. The radius of circle B is 44. What is the radius of circle

xxMikexx [17]

Formula:
$\bigg( \dfrac{radius_1}{radius_2} \bigg)^2 = \dfrac{area_1}{area_2}$

Plug in the values:
$\bigg( \dfrac{r}{44} \bigg)^2 = \dfrac{1}{121}$

Simplify LHS:
$\dfrac{r^2}{1936} = \dfrac{1}{121}$

Multiply by 1936 on both sides:
$r^2 = \dfrac{1936}{121}
$

Simplify RHS:
$r^2 = 16$

Square root both sides:
$r = 4$

Answer: The radius is 4 units. (Answer B)
