Answer:

number of parking spots

Step-by-step explanation:

3b + 4 is the same as (3 x b) + 4 so 4 is the illegal cars, b is the parking spots and 3 is the the cars in parking spots, so the only logical answer is the number of parking spots.

Viktor [21]

Question:

A small tie shop finds that at a sales level of x ties per day its marginal profit is MP(x )dollars per​ tie, where

MP(x) =1.85 + 0.12x - 0.0024x². ​Also, the shop will lose ​$65 per day at a sales level of x= 0. Find the profit from operating the shop at a sales level of x ties per day.

Answer:

P(x) = 1.85x + 0.06x^2 - 0.0008x^3 - 65

Step-by-step explanation:

MP(x) = 1.85 + 0.12(x) - 0.0024(x^2)

At sales level, x=0, loss = $65

P(0) = - $65

Integrating MP(x) with respect to x

P(x) = ∫MP(x) dx = ∫ 1.85 + 0.12(x) - 0.0024(x^2)

P(x) = 1.85x + 0.06x^2 - 0.0008x^3 + C

Therefore :

P(x) = 1.85x + 0.06x^2 - 0.0008x^3 - 65

PLEASE HELP ASAP ILL MAKE YOU THE BRAINIEST
jenyasd209 [6]

Answer:

A = 16803.2 in^2

Step-by-step explanation:

The area of a regular polygon is A=\frac{1}{2}(a)\cdot{P}, where a is apothem and P is the perimeter.

Given side length s = 59 in, and the knowledge that this is an octagon (8 sides): P = 8s.

  • Substitute the value of s into the equation: P=8(59)=472

Now substitute all known values into the area formula: A=\frac{1}{2}(71.2)\cdot{472}

  • Simplify: A=16803.2
