Answer:

The quadratic equation formula is used in algebra and can seem a little daunting at first because the formula itself is fairly complex compared with others one might have seen. However, it is quite easy to use the formula once you understand it. There are three different ways to solve quadratic equations. The first includes factoring, though not every math problem can be factored. The second is to complete the square, and the third way to solve these problems is to use the quadratic formula. There are many courses from Udemy that can help you learn in-depth algebra easily, but here is a quick overview of quadratic equations and the quadratic equation formula.

The quadratic equation looks like this: x2 – 3x + 2 = 0. The x is the unknown number and makes an equation that can be solved easily using one of the three ways—factoring, quadratic formula and squares.

A toy is made from a hemisphere, a cylinder and a cone is shown find the total are of a toy
qwelly [4]
Surface area of the cylinder = 2 pi r * 40  = 2 pi * 3* 40 =  24 pi
 of the cone this is pi * 3 * 5 = 15pi
of the hemisphere this is  1/2 * 4 * pi * 3^2  =   18pi

So the answer is 24pi + 15pi + 18pi = 57pi = 178.98 cm^2

f ( 7 ) = 2.4 ft

Step-by-step explanation:

Solution:-

- This is modeled using a geometric sequence function with initial height from which ball is dropped hi = 18 feet, and a decrease in height by 25% after each successive bounce :

                      f ( x ) = 18 (0.75)^x

Where,   x e [ 0 , ∞ ) : The number of bounces.

             f (x) : The maximum height after xth bounce.

- The maximum height reached by the ball after its 7th bounce. So, x = 7:

                       f ( 7 ) = 18 (0.75)^7

                       f ( 7 ) = 2.4027 ft

- To the nearest tenth:

                     f ( 7 ) = 2.4 ft

What is the total volume of all four lockers if one side of a locker is 2 feet long? ​
Anon25 [30]

Answer:

<em>32ft³</em>

Step-by-step explanation:

Let the shape of the locker be cubic in nature.

Volume of a cube = L³

L is the side length of one of the lockers

Volume of four lockers = 4L³

If one side of the locker is 2feet long, then L = 2ft

Substitute into the formula;

Volume of four lockers = 4(2)³

Volume of four lockers = 4(8)

Volume of four lockers = 32ft³

<em>Hence the total volume of all four lockers is 32ft³</em>
