kondaur [170]

Answer:

Calculators from the beginning of the third week to the end of the fourth week = 4048.

Step-by-step explanation:

We know that the rate of production of these calculators after t weeks is given by

\frac{dx}{dt} =5000(1-\frac{100}{(t+10)^{2}})

To find the number of calculators that have been produced in a period, we need to take the integral of the function above; the desired time is t=2 (beginning of third week) to t=4 (end of the fourth week). Therefore, the number of calculators produced in the given time is

\int\limits^4_2 {\frac{dx}{dt} } \, dt = \int\limits^4_2 {5000(1-\frac{100}{(t+10)^{2} }) } \, dt

Substitute t+10=u and dt=du, observe that the limits of integration will change

\int\limits^4_2 {\frac{dx}{dt} } \, dt => \int\limits^{14}_{12} {\frac{du}{dt} } \, dt

5000\int\limits^{14}_{12} { 1-\frac{100}{u^{2} } } \, du

5000(u+100u^{-1})\left \{ {{14} \atop {12}}\right.\\5000(2+\frac{100}{14}-\frac{100}{12} )\\4047.62 ≈ 4048

Explain how to find 80% of a number if 135% of that number is 540.
Dmitry_Shevchenko [17]

Answer:

x = 911.25

Step-by-step explanation:

let the number be x

by putting the word problem in equation, we get :

  • 80/100 × x = 135/100 ×540
  • 4/5 × x = 135/10 × 54
  • x = 135/10 × 54 × 5/4
  • x = 911.25

Someone please help me I am confuzzled+need the answer asap
denis-greek [22]

w = number of weeks

b(w) = number of books read after w weeks

====================================

b(w) = 12 translates to "after w weeks, Katy will have read 12 books" or put another way "Katy will have read 12 books after w weeks". The 'w' is a placeholder for some number

====================================

b(2) = 10 means "Katy has read 10 books after 2 weeks". We use the same basic idea talked about above, but we replace w with 2. At the same time, we use 10 instead of 12.

====================================

b(3) = f means "Katy has read f books after 3 weeks" or "after 3 weeks, Katy has read f books". Like w, the f is a placeholder for some number.
