The sum of the roots of a quadratic equation ax² + bx + c = 0 is given by -b/a.
Given equation:
x² - 3x - 4 = 0
a = 1
b = -3
Sum of roots = -(-3)/1
= 3
To find the ratio, we need to convert both measurements to the same unit. Let's convert feet to inches (1 foot = 12 inches).
3 feet = 3 * 12 = 36 inches
Now, the ratio is:
36 inches : 16 inches
To simplify, divide both numbers by their greatest common divisor (GCD), which is 4:
36 ÷ 4 = 9
16 ÷ 4 = 4
The simplified ratio is:
9/4
Is, am, are, was and were are examples of Auxiliary verbs.
In the sentence "I am playing football," the word "am" is an auxiliary verb (also known as a helping verb), which helps form the present continuous tense.
The main verb here is "playing."
Every number has at least two factors: 1 and the number itself.
For example, the number 7 has factors 1 and 7, making two factors in total.
To solve the proportion:
x : 12 :: 3 : 4
We can set up an equation based on the ratio:
x/12 = 3/4
Cross-multiply:
4x = 3 * 12
4x = 36
Divide both sides by 4:
x = 36/4
x = 9
قرآن حکیم (سورۃ الفرقان، آیت 67) میں فرمایا گیا
اور جب وہ خرچ کرتے ہیں تو نہ فضول خرچی کرتے ہیں اور نہ بخل، بلکہ ان دونوں کے درمیان اعتدال سے خرچ کرتے ہیں۔
مطلب یہ کہ رحمٰن کے بندے میانہ روی اختیار کرتے ہیں، اسراف نہیں کرتے۔
