Answer:
b=16
Step-by-step explanation:
Formula~ 1/2*b*h
1/2*15*b=120
7.5b=120
b=120/7.5
b=16
(you can substitute the value to check-i've done it below)
1/2*16*15=?
if you work it out, the ans will be 120, therefore the ans is correct!
Graph the trigonometric function using the amplitude,period,phase shift and vertical shift.
Vertical Asymptotes:x=pi/6 =pi n/2 where n is an integer
Amplitude is none
period is pi/2
phase shift is pi/6 to the right
vertical shift is 0
12z^2 - 7z -12/ 3z^2 + 2z - 8
= (4z+3) (3z -4)/ (z+2)(3z -4)
= (4z + 3) / (x+2)
Hope this helps
The inequality symbol in the picture stands for greater than or equal to, so 9, 11, 12 all apply in the equation
