Consider the following.3x + 3y = 8(a) Find y' by implicit differentiation.(b) Solve the equation explicitly for y and differenti

ludmilkaskok [199]

Answer:

a.y'=-1

b.y'=-1

c.Yes

Step-by-step explanation:

We are given that consider a function

$3x+3y=8$

Implicit function: That function is a relation in which dependent variable can not be expressed in terms of independent variable

Explicit function: It is that function in which dependent variable can be expressed in terms of independent variable.

a. $3x+3y=8$

Differentiate w.r.t x then we get

$3+3\frac{dy}{dx}=0$

$3\frac{dy}{dx}=-3$

$\frac{dy}[dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

b. $3x+3y=8$

$3y=8-3x$

$y=\frac{8-3x}{3}$

Differentiate w.r.t x then we get

$\frac{dy}{dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

When we substituting the value of y obtained from part b into a solution of part a then we get

$y'=-1$

Hence, solutions are consistent.

Answer:

The total volume is 41.1 cubic meters.

Step-by-step explanation:

Volume of the platform is:

1.8m * 1.8m * 10m = 32.4 m^3

Volume of the ramp is half of a prism with same dimensions as that ramp:

0.5 * 6m * 1.8m * 1.8m = 9.7 m^3

Total: (32.4 + 9.7) m^3 = 41.1m^3

Solve for r <br> 12r=36 pro

blsea [12.9K]

Answer:

r = 3.

Step-by-step explanation:

The equation means 12 x r = 36. Well to work this out we can do a reverse method using division. We're going to do 36 divided by 12. The answer to that is 3 so r = 3. Let's check it now! 12 x 3 = 36? That sounds correct to me so there's our answer.

Hope that helps. x
