Answer:
slope = - ![\frac{\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B3%7D)
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y
= 0
2y
= - 2x
= -
= - ![\frac{x}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D)
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2
⇒ y = ± 2![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
using x = - 2, y = - 2
, then
= -
= - ![\frac{\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B3%7D)
Answer:
.90 per pound
Step-by-step explanation:
just take 4.50 and divide it by 5 to get .90 and you can just check it by taking .90 and multiplying it by 5 and you still get 4.50 as the overall price
