andreev551 [17]

Answer:

a. 1620-x^2

b. x=810

c. Maximum value revenue=$656,100

Step-by-step explanation:

(a) Total revenue from sale of x thousand candy bars

P(x)=162 - x/10

Price of a candy bar=p(x)/100 in dollars

1000 candy bars will be sold for

=1000×p(x)/100

=10*p(x)

x thousand candy bars will be

Revenue=price × quantity

=10p(x)*x

=10(162-x/10) * x

=10( 1620-x/10) * x

=1620-x * x

=1620x-x^2

R(x)=1620x-x^2

(b) Value of x that leads to maximum revenue

R(x)=1620x-x^2

R'(x)=1620-2x

If R'(x)=0

Then,

1620-2x=0

1620=2x

Divide both sides by 2

810=x

x=810

R(x)=1620x-x^2

R(810)=1620x-x^2

=1620(810)-810^2

=1,312,200-656,100

=$656,100

I don’t get this question

faltersainse [42]

$\text{Use pythagorean theorem}$

$a^2 + b^2 = c^2 \longrightarrow a^2 +6^2=9^2 \longrightarrow a^2 =45\longrightarrow a =6.7082\longrightarrow a = 6.71$

$\textbf{a = 6.71}$

A point M on a segment with endpoints X(1, −2) and Y(10, 3) partitions the segment in a 4:1 ratio. Find M. You must show all wor

inna [77]

Answer:

$\displaystyle \: M = \left( 8\frac{1}{5},2\right)$

Step-by-step explanation:

we want to figure out the point "M" which is on a segment with endpoints X(1,-2) and Y(10,3) partitions the segment in a 4:1 ratio.

to find so, we can consider section formula . we know that Section formula is used to find the ratio in which a line segment is divided by a point internally or externally the ratio is written as m:n

however in this case the following formula can be used used:

$\displaystyle \left( \frac{m x_{2} +n x_{1}}{m + n} , \frac{m y_{2} + n y_{1}}{m +n}\right)$

step-1: assign variables

assign variables:

$(x_{1},y_{1}) = (1, - 2)$
$(x_{2},y_{2}) = (10, 3)$
$m : n = 4 :1$

step-2: substitute

$\displaystyle \left( \frac{(4) (10) +(1)(1) }{4 +1} , \frac{(4)(3)+ (1) ( - 2)}{4 +1}\right)$

simplify multiplication:

$\displaystyle \left( \frac{40 + 1 }{4 + 1} , \frac{12+ ( - 2)}{4 + 1}\right)$

simplify addition:

$\displaystyle \left( \frac{41 }{5} , \frac{10}{5}\right)$

simplify division:

$\displaystyle \left( 8\frac{1}{5},2\right)$

hence,

$\displaystyle \: M = \left( 8\frac{1}{5},2\right)$
