The equation of the tangent to the curve x^2 = 4y at the point on the curve where x=-2 is?
aleksandrvk [35]
x^2 = 4y \Rightarrow y= \frac{x^2}{4}
\frac{dy}{dx} = \frac{2x}{4} =  \frac{x}{2}

(x = -2) \frac{dy}{dx} = \frac{x}{2} =  \frac{-2}{2} = -1
(x = -2) y= \frac{x^2}{4}= \frac{(-2)^2}{4}  = 1

y-y_1=m(x-x_1)
y-1 = -1(x--2)

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

Elise picks 6 pounds of apples.She uses 1/2 pounds to make 1 container of apple sauce. How many containers of applesauce can Eli
Marina CMI [18]

Answer:

12

Step-by-step explanation:

  Mass of apples = number of containers × mass in each container

                     6 lb = No of containers × ½ lb

No of containers = 6/½  

To divide a whole number by a fraction, invert the fraction and change divide to multiply.

6/½ = 6 × 2/1

Multiply the numerator by the whole number.

6 × 2/1 = 12/1

Simplify the fraction.

12/1 = 12

Elise can make 12 containers of applesauce.
