Chose the graph that represents the equation y=|x-4|
evablogger [386]
You have not shared the graphs from which you have to choose your answer.

Why not graph y=|x-4| yourself, to help you choose the correct answer?

First, graph y=|x|.  It looks like a "v" opening up, with the vertex at (0,0).
Next, move the whole "v" graph 4 units to the right.  

Compare your result to the given answer choices.

Find the savings plan balance after 18 months with an APR of 3% and monthly payments of $200.
ArbitrLikvidat [17]

The saving plan balance is $3,677.53.

Given that,

  • The no of months is 18.
  • The annual percentage rate is 3% so the monthly rate percentage is 0.25%.
  • And, the monthly payment is $200.

Based on the above information, the following formula should be used:

FVA = PMT×  [(1+r)^n - 1] ÷ r

= $200 × [(1+ 0.0025)^18 - 1] ÷ 0.0025

= $3,677.53

Therefore we can conclude that the saving plan balance is $3,677.53.

Von Bertalanffy's equation states that the rate of growth in length of an individual fish is proportional to the difference betw
tiny-mole [99]

Answer:

dT/dt = k(L-Lt)

Step-by-step explanation:

Let the rate of growth in length be dL/dt

The difference between the current length L and the asymptotic length Lt will be expressed as L-Lt

If the rate of growth in length of an individual fish is proportional to the difference between the current length L and the asymptotic length Lt, this is expressed as;

dT/dt ∝ L-Lt

dT/dt = k(L-Lt) where

k is the proportionality constant

Hence the differential equation that expresses this idea is written as;

dT/dt = k(L-Lt)
