Answer: I am really good at math so if you need help just say so
Standard form is just the number. The answer is 405.
Answer:
Distance between the person and the plane is 12 miles
Step-by-step explanation:
From the figure attached,
An airplane is flying at an altitude AB = 6 miles.
An observer is standing at point C from where he observes the plane at an angle of elevation θ
Therefore, sinθ = 
sinθ = 
AC = 
AC = 6cosecθ
If angle θ = 30°
Then AC = 6cosec30
AC = 6×2
AC = 12 miles
Therefore, distance between the person and the plane is 12 miles.
S=16t^2
if t=3
So you would plug it in
16(3)^2
Then you multipy
16*3^2
=144
It is easier if you use a calculator just type in ti 30 calculator online that should help
Step-by-step explanation:
1st expression
= px^4 + px
= px ( x³ + 1 )
= px ( x + 1) (x² - x + 1)
2nd expression
= qx³ - qx
= qx ( x² - 1 )
= qx ( x + 1) ( x - 1)
HCF = x ( x + 1)
Hope it will help :)❤
