Prior to September, 2000, taxi fares from Washington DC to Maryland were described as follows: $2.00 up to and including 1⁄2 mil

GREYUIT [131]

The piecewise function is

f(x) = 2, 0 < x ≤ 1/2

f(x) = 2 + 0.7x, x > 1/2

<h3>How to determine the piecewise function?</h3>

From the question, we have:

Fares = $2.00 ⇒ up to (and including) 1/2 miles

Fares = $0.70 increment ⇒ greater than 1/2 miles

Let x represent the number of miles, and f(x) the fares.

So, we have:

f(x) = 2, 0 < x ≤ 1/2

f(x) = 2 + 0.7x, x > 1/2

The above represents the piecewise function

Evaluate the expression 3 4/5x-2 1/2 for x =-10

lyudmila [28]

Answer:

The value of given expression for x = - 10 is - 81

Step-by-step explanation:

Given expression as :

3 $\frac{4}{5}$ x - 2 $\frac{1}{2}$

Or, 3 + $\frac{4}{5}$ x - 2 - $\frac{1}{2}$

Or, $\frac{19}{5}$ x - $\frac{5}{2}$

or, $\frac{38 x - 25}{5}$

Now for x = - 10

$\frac{38\times (- 10) - 25}{5}$

Or, ${38\times (- 2) - 5}$

∴ - 76 - 5

Or, - 81

Hence The value of given expression for x = - 10 is - 81 Answer

The time, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters

Serhud [2]

Answer:

$d=\dfrac{t^2}{a}$

Step-by-step explanation:

The time in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.

t = va

We need to find the expression for d in terms of t and a.

As velocity = distance/time

$t=\dfrac{d}{t}a\\\\t^2=da\\\\d=\dfrac{t^2}{a}$

So, the distance d is $\dfrac{t^2}{a}$ .
