Simplify the expression: 4b - 24 + 19 4p - 5p - 30p 4.2v - 5 - 6.5v

1 answer:

4 0

For the first expression we will only simplify the constants:

4b - 24 + 19 ——> 4b - 5

The second expression only has variables so we simplify the whole expression

4p - 5p - 30p = -31p

The third expression we will only simplify the variables

4.2v - 5 - 6.5v ——> -2.3v - 5

The average ticket price for a concert at the opera house was $50. The average attendance was 4000. When the ticket price was ra

kotegsom [21]

Answer

given,

opera house ticket = $50

attendance = 4000 persons

now,

opera house ticket = $52

attendance = 3800 person

assuming these are the points on the demand curve

(x, p) = (4000,50) and (x,p) = (3800,52)

using point slope formula

$p-50 = \dfrac{50-52}{4000-3800}(x - 4000)$

$p-50 = \dfrac{-2}{200}(x - 4000)$

$p-50 = \dfrac{-x}{100}+ 40$

$p = \dfrac{-x}{100}+ 90$

R(x) = x . p

$R(x) = x (\dfrac{-x}{100}+ 90)$

$R(x) = \dfrac{-x^2}{100}+ 90x)$

$\dfrac{d}{dx}(R(x)) = \dfrac{d}{dx}(\dfrac{-x^2}{100}+ 90x))$

$\dfrac{d}{dx}(R(x)) = (\dfrac{-2x}{100})+90)$

at $\dfrac{d}{dx}(R(x)) = 0$

$\dfrac{-2x}{100}= -90$

x = 4500

$\dfrac{d^2}{d^2x}(R(x)) = -ve$

hence at x =4500 the revenue is maximum

for maximum revenue ticket price will be

$p = \dfrac{-4500}{100}+ 90$

p = $45

Reduce the fraction 36/48 to its lowest term

QveST [7]

Answer:

3/4

Step-by-step explanation:

$\dfrac{36}{48}=\dfrac{3\cdot 12}{4\cdot 12}=\dfrac{3}{4}\cdot\dfrac{12}{12}\\\\=\dfrac{3}{4}\cdot 1=\dfrac{3}{4}$

Effectively, divide both numerator and denominator by their greatest common factor, 12.

The coordinate of two point P(4,6) and Q(5,-7) then find (abicissa of P) -(abicissa of Q)

grandymaker [24]

The value of (abscissa of P) -(abscissa of Q) is -1.

The given coordinates are P(4,6) and Q(5,-7).

We need to find (abscissa of P) -(abscissa of Q).

<h3>What is abscissa?</h3>

The horizontal coordinate of a point in a planar Cartesian coordinate system that is determined by measuring parallel to the x-axis is what abscissa stands for.

Now, (abscissa of P) -(abscissa of Q)=4-5=-1

Hence, the value of (abscissa of P) -(abscissa of Q) is -1.
