Answer:
henc X = 30°
Step-by-step explanation:
here is the proof
when X=30° then
sin2x = sin2×30
=sin 60°
= √3/2
or else,
putting value of X = 30° then
sin2x= 2sinxcosx
= 2×sin30°×cos30°
=2×1/2×√3/2
= 2√3/4
= √3/2
hence proved sin2x= √3/2.
12x2-7=6-2x2+2
14x^2-15=0
a=14 , b =0 , c=-15
0^2-4x14x(-15) =
840
First, subtract 14 from 153.80 to get the ticket prices alone. You would get 139.8
Then, since they’re buying 4 tickets, you divide 139.8 by four to get the individual ticket pricing,
meaning your final answer would be $34.95
153.80=4x+14 ⬅️ y-int form if you need that to solve
Answer:
A diver can descend 2 feet every minute. If the diver descends for four minutes, where will the diver be in relation to the surface?
Step-by-step explanation:
If the surface is 0 and the diver descends a total of eight feet, then the diver would be at a position of -8 feet.
