Answer:
9
Step-by-step explanation:
Plug in 2 for x
You should get f(2)=(2+1)^2
Add 2+1 inside the parenthesis to get 3
Finally do (3)^2 to get 9
Answer:
Slope of given line = 
and slope of perpendicular line = 
Step-by-step explanation:
We are given a line -9x - 4y = 5 .
We have to find the slope of a line parallel to this line and also a line perpendicular to this line.
Let the general equation be ax + by = c.
Then the slope of this line = 
=
The slope of a line perpendicular to a line is the negative inverse of the slope of the line. Using this concept,
Slope of line perpendicular to the given line = 
=
Answer: C; y=csc(x)+1
Step-by-step explanation: just graphed them on desmos until i got the right one :)
Let 's x the width of the sidewalk.
Area of the swimming pool= 10*16=160 (ft²)
Area of the sideway+the swimming pool= (16+2x)*(10+2x) =160+155
==>160+20x+32x+4x²=160+155
==>4x²+52x-155=0
Δ=52²+4*4*155=5184=72²
==>x=(-52+72)/2=5/2 or x=a negative to exclude.
Width of the sideway=5/2 ft
so tell me if i helped
