Answer:

$546,875

Step-by-step explanation:

if the trailer brand new costs $625,000 and decreases by 12.5% you want to find 10% which is $62,500. then you want to find 5% which would be $31,250. but you want 2.5% so you need to divide $31,250 by 2 which is $15,625. add $62,500 and $15,625 together which is $78,125. then do $625,000-$78,625 which gets you $546,875.

if you double the input of a function and it results in twice the output and if you triple the input and it result in three time

bearhunter [10]

A function behaving as you state is a linear function, which means that the output varies directly with the input.

So, there exists some constant $k \in \mathbb{R}$ such that your function is in the form

$f(x) = kx$

In fact, if you double the input, you have

$f(2x) = k\cdot(2x) = 2\cdot (kx) = 2f(x)$

And similarly

$f(3x) = k\cdot(3x) = 3\cdot (kx) = 3f(x)$

Note that this is a guess, it may happen that output doubles (triples) if you double (triple) the input, and still the function is not like $y=kx$ .

For example, the function

$f(x) = \dfrac{x^3}{3} - 2x^2 + \dfrac{14}{3}x -2$

is such that

$f(1) = 1,\ f(2) = 2,\ f(3) = 3$

So, it may seems that doubling and tripling the input doubles and triples the output, but this is not true for every input, for example,

$f(2) = 2,\ f(4) = 6$

And so doubling the input didn't double the output.

Liquid A and liquid B are mixed to make liquid C.

natta225 [31]

Answer:

Density is defined as:

Density = mass/volume.

We know that:

For liquid A:

Density = 70kg/m^3

Mass = 1400kg

Then the volume is:

Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3

For liquid B:

Density = 280 kg/m^3

Volume = 30m^3

We can find the mass of liquid B as:

mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg

We know that liquid C is a mixture of liquid A and B.

Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:

Mass of liquid C = 1400kg + 8400kg = 9800kg

The same happens for the volume, then:

Volume of liquid C = 30m^3 + 20m^3 = 50m^3

Then the density of liquid C is:

Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3
