It is given that the difference between the zeros of 4x^2 -8kx+9 is 4 and k>0.Find the value of k.

Answer»

Let the zeroes be a and b
a - b = 4
a + b = 2k
ab = 9/4
(a - b)^2 = (a + b)^2 - 4ab
16 = 4k^2 - 9
k^2 = 25/4
k = 5/2 or -5/2
since k is greater than 0 so
k = 5/2

It doesn't not matter whether you take a - b or a + b in this QUESTION particularly as we have to square it in further steps but for other questions we NEED to take separate cases for difference of the ROOTS because we don't KNOW which one is greater.
Hope this HELPS!!!!!

Sonal reads 2/5of a book.she find that there are still 120 page left to be read .how many pages are there in the book?

Answer»

HYE

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

let total be X


=> Sonal read 2 by 5 of a book
=>2/5x

=>she find that there are still 120 PAGES left to be read

so  let us from an EQUATION

=>2/5 of x = 120


=>2/5 *x = 120


=>x = 120 *5/2

=>x = 600  / 2

=>x = 300 pages


so there are 300 pages


====================
lets check


2/5 of 300 pages


=>2/5 *300


=>600/5


=>120 pages

Blunting of the left costophrenic angle home remedies

Answer»

Lung is one of the vital organs of our body. Lungs facilitate inhalation of oxygen and EXHALATION of carbon di-oxide. Diseases and pathological CHANGES of the lungs affect the breathing of an individual. There can be many reasons for a pathological condition to develop in the lungs. Breathing is affected when lungs are compressed from outside. The lungs are compressed from outside when air or water is trapped between lung and chest wall. Fluid around the lung causes a DISEASE known as pleural effusion. Pleural effusion causes Costophrenic Angle BLUNTING. In this ARTICLE, we will discuss about Costophrenic Angle Blunting in detail, the radiological changes, and how to correct the deformity.
