you have slope of tangent ryt

#

you can finnd slope of normal using $m_1 m_2=-1$

pratham

zinc slate Jul 8, 2024, 8:42 AM

#

and then proceed

gloomy basin Jul 8, 2024, 8:43 AM

#

zinc slate you have slope of tangent ryt

this is prob a dumb question but wat is the slope of the tangent?

#

is it the point (3,2)?

zinc slate Jul 8, 2024, 8:44 AM

#

gloomy basin this is prob a dumb question but wat is the slope of the tangent?

its given ryt

#

gradient of tangent at P is 3/2

gloomy basin Jul 8, 2024, 8:45 AM

#

oh yea so i need to find the gradient of the first derivative then?

#

and thne i just do wat u showed me earlier

zinc slate Jul 8, 2024, 8:46 AM

#

gloomy basin oh yea so i need to find the gradient of the first derivative then?

slope of tangent is given to you
you need to find slope of normal

gloomy basin Jul 8, 2024, 8:58 AM

#

zinc slate slope of tangent is given to you you need to find slope of normal

for ii i got y = -2/3x + 13/3 i just need to rearrange it now right?

zinc slate Jul 8, 2024, 9:02 AM

#

yup

gloomy basin Jul 8, 2024, 9:03 AM

#

zinc slate yup

how do i do iii now?

gloomy basin Jul 8, 2024, 9:04 AM

#

yes

zinc slate Jul 8, 2024, 9:05 AM

#

its basically a triangle

#

if you figure out intercepts you are done

gloomy basin Jul 8, 2024, 9:06 AM

#

ok imma get back to u once im done thx btw

zinc slate Jul 8, 2024, 9:06 AM

#

gloomy basin ok imma get back to u once im done thx btw

np

gloomy basin Jul 8, 2024, 9:11 AM

#

zinc slate np

this looks wrong but i got 6.5 for the x intercept and 4.3recurring for the y intercept

zinc slate Jul 8, 2024, 9:12 AM

#

its correct

#

13/2,13/3

#

now just find area of that triangle

gloomy basin Jul 8, 2024, 9:13 AM

#

so times then /2 which is 14.08

#

or do i leave it in fractions?

zinc slate Jul 8, 2024, 9:18 AM

#

gloomy basin or do i leave it in fractions?

idk how are you supposed to answer it

#

in decimal form of fraction form

gloomy basin Jul 8, 2024, 9:18 AM

#

ok

#

how do i do the helper nominate thing to u?

zinc slate Jul 8, 2024, 9:23 AM

#

gloomy basin how do i do the helper nominate thing to u?

in that perticular channel maybe #helper-nominations

#

but thanks for doig that it means a lot

#

what does w mean btw

gloomy basin Jul 8, 2024, 9:24 AM

#

i think i did it wrong lol

#

well literally it means win
