F(a+1)=(a+1)^2+1
=a^2+2a+1+1
=a^2+2a+2
It's D, because the slope is 3/5, and since the shaded area is above the line, y has to be greater than the other side of the inequality.
11.3 feet.
12 squared (144) minus 4 squared (16) is equal to 128. The square root of 128 is approximately 11.3.
The equation that runs through the location (4,-6) has the slope-intercept form,
.
<h2>Formation of the equation</h2>
A line's equation written in the slope-intercept form:
y=mx+b
where m= slope & b= y-intercept
The slope of two parallel lines is equal.
Currently, we know the line's equation:

here, slope, m= 
A line equation is created by adding the slope's value and the point's coordinates (4, -6):

⇒ -6=-3 +b [adding 3 to both sides]
⇒-3=b
⇒b= -3
Hence the solution is
.
