Step-by-step explanation:

{EF}^{2} =   {EG}^{2}   -  {FG}^{2}  \\  \\  =  {8}^{2}   -  {6}^{2}  \\  \\  = 64 - 36 \\  \\  = 28 \\  \\  \therefore \:  {EF} =  \sqrt{28}  \\  \\ \therefore \:  {EF} =  2\sqrt{7}  \\  \\  \sin \: E =  \frac{FG }{EG}  =  \frac{6}{8}  =  \frac{3}{4}  \\  \\   \huge\red {\boxed{\therefore \:  \sin \: E = \frac{3}{4}} } \\\sec \: G =  \frac{ EG}{FG}  =  \frac{8}{6}  =  \frac{4}{3}  \\  \\   \huge\purple {\boxed{ \therefore \: \sec \: G = \frac{4}{3}}} \\\\\cot \: G =  \frac{ FG}{EF}  =  \frac{6}{2\sqrt 7}  =   \frac{3}{\sqrt 7}  \\  \\  =   \frac{3\times\sqrt 7 }{\sqrt 7\times\sqrt 7 }  \\  \\  =   \frac{3\sqrt 7 }{ 7 }  \\  \\   \huge\orange {\boxed{ \therefore \: \cot \: G =  \frac{3\sqrt 7 }{ 7 } }} \\\\

SOLUTION OF TRIANGLE:

a i) use this formula, a² = b² + c² - 2bc cos A

a² = 8² + 10² - 2(8)(10) cos 60
= 84
a = 9.17 cm

UW = 9.17 cm

ii) use formula no 12 as attached :

sin
to solve this,

( sin 40 / 11 ) x 9.17 = 0.5358511

press shift sin on ur calc & the answer is :


FUNCTION

a) f(x) = x-3
g(x) = x²-1

i) f(6) = 6-3

substitute x with the value given in the bracket into equation

f(6) = 6-3
= 3

ii) to do inverse function use this formula :

u = f(x)
u = x - 3

and then make x as the subject

x = u + 3

after that, just change u to x

f-1(x) = x + 3

iii) f [ g(2) ] = f [ g(-2) ] = 0

g(2) = (2)² - 1 g(-2) = (-2)² - 1

= 4 - 1 = 4 - 1
= 3 = 3

f(3) = 3-3
= 0

Every morning Sasha exercises for 20 minutes. She exercises k minutes every evening. Next week she will double her exercise time
lapo4ka [179]
If k=20 minutes
Each day Sasha will exercise 2 times more. 2 times more than k is 2k.
So first week Sasha will exercise k+2k+3k+4k+5k+6k=20+40+60+80+100+120=440 minutes
The formula to show how long Sasha will exercise each day next week is:
440 + 20*x
where 440 is initial exercise time, and x is number of day in next week.
