Answer:
g(x)=x2−x−6g(x)=x2-x-6
Set x2−x−6x2-x-6 equal to 00.
x2−x−6=0x2-x-6=0
Solve for xx.
Tap for fewer steps...
Factor x2−x−6x2-x-6 using the AC method.
Tap for more steps...
(x−3)(x+2)=0(x-3)(x+2)=0
If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.
x−3=0x-3=0
x+2=0x+2=0
Set x−3x-3 equal to 00 and solve for xx.
Tap for more steps...
x=3x=3
Set x+2x+2 equal to 00 and solve for xx.
Tap for more steps...
x=−2x=-2
The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.
x=3,−2
Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
Angles in a triangle add up to 180°
Since it's a right angled triangle one of it's angles is 90°
So for angle F we have
F + 25 + 90 = 180
F = 180 - 115
<h3>F = 65°</h3>
To find GH we use tan
tan 25 = FG / GH
FG = 7m
tan 25 = 7 / GH
GH = 7 / tan 25
<h3>GH = 15.0 m</h3>
To find FH we use sine
sin 25 = FG / FH
sin 25 = 7 / FH
FH = 7/sin 25
<h3>FH = 16.6 m</h3>
Hope this helps you
1st: -2*2^(1-1) = -2*1 = -2
4th: -2*2^(4-1) = -2 *8 = -16
8th = -2*2^(8-1) = -2*128 = -256
Last choice is correct
