(x+1)2-
=it is meant to be (x+1)2
=2(x) + 2(1)
= 2x +2
I think
Given that

, then

The slope of a tangent line in the polar coordinate is given by:

Thus, we have:

Part A:
For horizontal tangent lines, m = 0.
Thus, we have:

Therefore, the <span>values of θ on the polar curve r = θ, with 0 ≤ θ ≤ 2π, such that the tangent lines are horizontal are:
</span><span>θ = 0
</span>θ = <span>2.02875783811043
</span>
θ = <span>4.91318043943488
Part B:
For vertical tangent lines,

Thus, we have:

</span>Therefore, the <span>values of θ on the polar curve r = θ, with 0 ≤ θ ≤ 2π, such that the tangent lines are vertical are:
</span>θ = <span>4.91718592528713</span>
x has two values 4 and 5 by factorization or using the general formula
Answer:
D. y=30x
Step-by-step explanation:
So x represents like say if he mowed 3 yards.
y=30(3)
Then y would equal 90
