The correct answer is C. <span>f(x)=20(35)x</span>
Multiply price per pound by total pounds:
2.50 x 3.5 = 8.75
Total cost = $8.75
The answer is c because it makes the most sense
R = 8 tan(x) sec(x)
In order to solve this, we are going to use the following:
r = sqrt(x^2 + y^2) //but in this case, we don't need this.
tan(x) = Y / X
X = r cos(x)
Y = r sin(x)
<span>(r cos x)^2 = 8(r sin x)</span>
x^2 = 8y
