Question

i have certain questions on introduction to history of math

Answer 1

@ganeshie8 kindly

Answer 2

which question ?

Answer 3

question 1 and 3 please

Answer 4

sorry 1 and 4 please

Answer 5

lets see #4 first

Answer 6

yea sure

Answer 7

\(\large \frac{1}{7} \uparrow \) and \(\large \frac{1}{9} \downarrow \)

that doesn't tell us the net effect visully, so lets change both fractions to a common base so that comparison becomes easy

Answer 8

ok cool..

Answer 9

please proceed further

Answer 10

sir is available ?

Answer 11

the post button keeps hiding and the page never loads, its really frustrating

Answer 13

ha... fine,,,, i have found a way to sort out question 1, but i need help for the above question and 5 too

Answer 14

dont let me down kindly, thank you

Answer 15

\(\large \frac{1}{7} \uparrow \) and \(\large \frac{1}{9} \downarrow \)

is same as

\(\large \frac{9}{63} \uparrow \) and \(\large \frac{7}{63} \downarrow \)


So it climbs 9/63 handbreadths and falls back 7/63 handbreads,
the net effect is\(\large \frac{2}{63} \uparrow \), yes ?

Answer 16

Overall, the lion climbs UP 2/63 handbreadths each day

Answer 17

yes i get what u say

Answer 18

and the pit is 50 handbreadth deep
so divide 2/63 to get number of days the lion takes to reach the top

Answer 19

50 handbreadths to climb up

2/63 handbreadth per day

So number of days it takes = 50/(2/63) = ?

Answer 20

315/2=157.5

Answer 21

3150/2 = 1575

Answer 22

sorry 3150/2

Answer 23

thank you!!!

Answer 24

question 5 please

Answer 25

You're given \[\large a_n = 2a_{n-1} - 12 ;~~a_4 = 9\]

Answer 26

You need to find \(\large a_0\)

Answer 27

familiar with recursive sequences ?
if not, we can work it using another method

Answer 28

no am not

Answer 29

but u can teach me

Answer 30

there ??

Answer 31

say he had "x" denari in the beginning

Answer 32

start : x

Lucca : 2x-12

Florence : 2(2x-12) - 12

Pisa : 2[2(2x-12)-12] - 12

Answer 33

set the last expression equal to 9 and solve x

Answer 34

2[2(2x-12)-12] - 12 = 9

x = ?

Answer 35

just a moment

Answer 36

8x-72=9

Answer 37

8x=81

Answer 38

doesn't look correct, check ur work again

Answer 39

sorry i left a 12

Answer 40

8x=93

Answer 41

thats what i got. is it correct ?

Answer 42

Thanks sir

Answer 43

looks good to me, check if it really satisfies the given situation by starting with 93/8 and carrying out the given sequence of steps
