y = mx + b   is the slope-intercept form of a line   where m= slope and b = y-axis intercept

for your question   m = 6     b = -4

y= 6x -4  

364 = 3n+5

359 = 3n

n = 119.666666.....

Nope, it is NOT in the sequence.  The answer for 'n' needs to be a whole number, not a fraction or decimal.

Don't know, but on the TI it might be labeled  'INV'   for inverse......

....or it could be the blue button in the upper left corner labelled  ' 2nd '

Ditto.    'Angry'     not 'mad'

Hit the  ' 2nd'  button first, then the sin button.

It's not Winter yet....it is still Autumn (fall) until approx Dec 21st.

Hey Omi67.....when I substitute your answer into the equation I get  -2    NOT   2  ......Hmmmmmm

I question this step(s)

Substitution  4x = u

u^2 - 2u -1 = 0                 u^2 would be 16x^2   NOT     4^(2x)         right???

Hey Omi67.....when I substitute your answer into the equation I get  -2    NOT   2  ......Hmmmmmm

First you will need to find time, 't' to reach the apex (high point) ....this is where the y component of velocity is ZERO.

y component =  18 sin 52 =  14.184 m/s

Now   vf = vo + at     vf = velocity final = 0      vo = velocity original (14.184 m/s from above)

0 = 14.184 + (-9.8)t

    results in t= 1.4473  seconds

THEN    yf = yo + vt + 1/2 at^2

               ? = 1  + 14.184 (1.4473) +(1/2)(-9.8)(1.4473)^2  = Max height= final 'y' = 11.26 m
