Answer:

y = -4/3x +23/2

Step-by-step explanation:

The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.

The center of the circle can be found by completing the square for each variable.

(x^2 -2x) +(y^2 +4y) = 20

(x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4

(x -1)^2 +(y +2)^2 = 25

Comparing this equation to the standard form equation for a circle, we can find the center.

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)

The center of circle P is (1, -2).

The slope m' of the line segment between (1, -2) and (5, 1) is given by ...

m' = (y2 -y1)/(x2 -x1)

m' = (1 -(-2))/(5 -1) = 3/4

The slope m of the perpendicular line is the opposite reciprocal of this, so is ...

m = -1/m' = -1/(3/4) = -4/3

The y-intercept of the desired line can be found from ...

b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)

b = 1 -(-4/3)(5) = 23/3

Then the equation of tangent line AB is ...

y = mx +b

y = -4/3x +23/3

The olive trees in an orchard produce 3,000 pounds of olives a year. It takes 20 pounds of olives to make 3 liters of olive oil.

AleksAgata [21]

Answer:

450L

Step-by-step explanation:

This is a ratio and proportion problem. First you need to determine the known ratio and the unknown ratio. In this case we have the known ratio:

$\dfrac{20 lbs}{3L}$

The unknown ratio in this case is:

$\dfrac{3,000lbs}{xL}$

So to do this, we just set up the proportion and solve for it:

$\dfrac{20lbs}{3L}=\dfrac{3,000lbs}{xL}\\\\{20lbs}=\dfrac{3L\times3,000lbs}{xL}\\\\{xL}=\dfrac{3L\times3,000lbs}{20lbs}\\\\{xL}=\dfrac{9,000L}{20}\\\\xL = 450L$

Simplify the following rational expression.

Jet001 [13]

Answer:

(x-8)/(4x-4) x ≠ 1 or 8

Step-by-step explanation:

Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.

$\dfrac{x^2-16x+64}{4x^2-36x+32}=\dfrac{(x-8)^2}{4(x-8)(x-1)}=\boxed{\dfrac{x-8}{4x-4}}$

The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.
