Answer:

Zero

Step-by-step explanation:

We are given the following expression and we are to determine what is the sign of its product:

$4 . 3 . ( - 3 . 2 ) . 0$

One of the three terms in the expression is positive while one is negative. So if we start multiplying the two terms from the left side. we will get a negative number.

But when we will multiply it with zero, the whole product will become zero as anything times zero is always zero. Therefore, answer will be zero.

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of abou

Karolina [17]

Answer:

A)The required linear demand equation ( q ) = -4500p + 41500

B) $4.61

$95680.55

C) No it would not have been possible by charging a suitable price

Step-by-step explanation:

A) find the linear demand equation

given two points ; ( 3, 28000 ) and ( 5, 19000 )

slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )

= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500

slope intercept is represented as ; y = mx + b

where y( 28000) = -4500(3) + b

hence b = 41500

hence ; y = -4500x + 41500

The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )

p = price per ride

B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue

Total revenue ( R ) = qp

= p ( -4500p + 41500 )

hence R = -4500p^2 + 41500p ------ ( 2 )

To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c

where a = -4500 , b = 41500 , c = 0

hence p = $-\frac{b}{2a}$ = $- \frac{41500}{2(-4500)}$ = 4.61

$4.61 is the price the company should charge to maximize revenue from ridership

corresponding daily revenue = R = -4500p^2 + 41500 p

where p = $4.61

hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55

C) No it would not have been possible by charging a suitable price

-3(5)^2-(-2)(-8) simplify

avanturin [10]

To do this, we're going to use the order of operations (PEMDAS):

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.

Next let's look for exponents. I see we have a $5^2$ so let's replace that with $5^2=25$ :

$-3(25)-(-2)(-8)$

Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:

$-3(25)=-75$

$(-2)(-8)=16$

$-75-16$

And now we're left with a simple problem we know how to solve.

Answer: $-91$

Hope this helps!

sume of angles of a triangel greater than 180 degrees when teh triange is so large that it extends to cosmological scales

Vesna [10]

In hyperbolic geometry, the angle sum of a triangle is always less than 180 degrees.

A lune is a wedge of a sphere with angle θ, represented by L(θ) in the proof.

α, β, and γ are the three angles of the triangle.

4πr²+4area[αβγ]=2L(α)+2L(β)+2L(γ)

2(2πr²+2area[αβγ])=2(L(α)+L(β)+L(γ))

2πr²+2area[αβγ]=L(α)+L(β)+L(γ)

At this point, we need to use a theorem that states that a lune whose corner angle is θ radians has an area of 2θr².

2πr²+2area[αβγ]=2αr²+2βr²+2γr²

2πr²+2area[αβγ]=2r²(α+β+γ)

π+area[αβγ]r²=α+β+γ

At this point, it is clear that the sum of the angles is equal to π plus the area[αβγ]r² (which cannot be zero).

Softa [21]

Answer:

150/335, or 30/67

Step-by-step explanation:

Probability is expressed as the part against the whole (a fraction). All you have to do is divide how many people ran red lights by the total...and you're done!

Have a great day!
