If the distance traveled is (4s3 - 6s² + 4s + 14) miles and the rate is (s + 1) mph, write an expression, in hours, for the time
BartSMP [9]

The equation for time is URM:

time =  \frac{distance}{speed \: (rate)}

t(s) =  \frac{4s {}^{3}  - 6s {}^{2}  + 4s + 14}{s + 1}  =  \frac{2(s + 1)(2s {}^{2} - 5s + 7) }{s + 1}  \\  t(s) = 2(2s {}^{2}  - 5s + 7) \\ t(s) = 4s {}^{2}  - 10s + 14

The equation 3y=5x represents a proportional relationship. what is the constant of proportionality for this relationship
Citrus2011 [14]

The constant of proportionality for this relationship is  \frac{5}{3}

Step-by-step explanation:

Proportional relationship is the relation between two variables that vary directly with each other

  • If x and y are proportion, then y = k x, where k is the constant of proportionality
  • If x and y are proportion, then \frac{y}{x}=k, where k is the constant of proportionality

∵ The equation is 3 y = 5 x

∵ x and y are proportional

- That means y = k x, where k is the constant of proportionality

∴ Put the equation in the form y = k x

- Divide both side by the coefficient of y

∵ The coefficient of y is 3

∴ Divide both sides of the equation by 3

∴ y = \frac{5}{3} x

-  The value \frac{5}{3}  is constant

∴ k =  \frac{5}{3}

∵ k represents the constant of proportionality

∴ The constant of proportionality =  \frac{5}{3}

The constant of proportionality for this relationship is  \frac{5}{3}

315 people have to be transported using buses that have 37 seats. By typing one line (command) in the Command Window, calculate
LuckyWell [14K]

Answer:

18

Step-by-step explanation:

seats left = 37*ceil(315/37)-315

<=> seats left = 18

So, to fit 315  people into buses with 37 seats, the number of buses are celi(315/37) and the number of seats left is 37*celi(315.37) -315
