This is for leadership
Nikolay [14]

Answer:

I don't think many schools do Powderpuff which is where boys cheer and girls play football. You can do a live Insta and congratulate the students who made the team and mail them gift cards and/or gift baskets. You can also buy basket balls and footballs for each member and decorate it with their names and numbers. I'm also in Student Council so, if you have any other questions feel free to post them!!

Find the second derivative of 2x^3-3y^2=8​
Umnica [9.8K]

Answer:

\frac{d^2y}{dx^2}=\frac{x(2y-x^3)}{y^3}

Step-by-step explanation:

<u>Find the first implicit derivative using implicit differentiation</u>

<u />2x^3-3y^2=8\\\\6x^2-6y\frac{dy}{dx}=0\\ \\-6y\frac{dy}{dx}=-6x^2\\ \\\frac{dy}{dx}=\frac{x^2}{y}

<u>Use the substitution of dy/dx to find the second derivative (d²y/dx²)</u>

<u />\frac{d^2y}{dx^2}=\frac{(y)(2x)-(x^2)(\frac{dy}{dx})}{y^2}\\ \\\frac{d^2y}{dx^2}=\frac{2xy-(x^2)(\frac{x^2}{y})}{y^2}\\\\\frac{d^2y}{dx^2}=\frac{2xy-\frac{x^4}{y}}{y^2}\\\\\frac{d^2y}{dx^2}=\frac{x(2y-x^3)}{y^3}

A motorboat travels 60 km in 4 hours with the current and 35 km in 3.5 hours against the current. Find the speed of the boat in
IceJOKER [234]

Step-by-step explanation:

Distance = rate × time

If b is the speed of the boat in still water, and c is the speed of the current, then:

60 = (b + c) × 4

35 = (b − c) × 3.5

Simplifying:

15 = b + c

10 = b − c

Add the equations together:

25 = 2b

b = 12.5

Plug into either equation to find c:

c = 2.5

The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.

Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

The top has area (3 cm)(5 cm), or:                                 15 cm^2

The bottom has the same area:                                      15 cm^2

Each of the ends has the area (3 cm)(2.5 cm):                7.5 cm^2

                                                                                           7.5 cm^2

Each of the sides has the area (2.5 cm)(5 cm)                12.5 cm^2

                                                                                            12.5 cm^2

                                                                                        -------------------

                                                                                             70 cm^2

The total lateral area is 70 cm^2
