Answer:9/16
Step-by-step explanation:
Since we know it's 3/4 use
r=(3/4)² ....
=
The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be

Step-by-step explanation:
5(tanx)^2 -2 +tanx=0
let tanx=y
5y^2 + y-2=0
y=0.5403 or y= -0.7403
tanx=0.5403
x=arctan(0.5403)
x=28.38°
or
tanx=-0.7403
x=arctan(-0.7403)
x=143.49°
9) x= -6
10) x= 3/2
11) x= -4,0,5
12) no solution
Y = 6x - 4
basically, we just sub answer choices in to see which ones make the equation true.
answer is : (0,-4) , (1,2) , (3,14)
