gulaghasi [49]3 years ago
5 0

Answer:

≈ 23 years

Step-by-step explanation:

Initial price= $995

Value increase= 3.1%

a)  $995 +3.1%= $995*1.031= $1025.85

b)  $995*1.031^x= $2000

1.031^x= 2000/995

1.031^x= 2.01

x= log 2/log 1.031= 22.7 ≈ 23 years

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm. Calculate the volume of
never [62]

Answer:

The volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

Step-by-step explanation:

Formula

Volume\ of\ a\ cylinder = \pi r^{2} h

Volume\ of\ a\ cone = \pi r^{2} \frac{h}{3}

Where r is the radius and h is the height .

As given

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm.

\pi = 3.14

Thus

Volume\ of\ a\ cylinder =3.14\times 5\times 2\times 2

                                             = 62.8 cm³

Thus the volume of a cylinder is 62.8 cm³ .

Volume\ of\ a\ cone = 3.14\times 2\times 2\times frac{5}{3}

Volume\ of\ a\ cone =\frac{5\times 3.14\times 2\times 2}{3}

Volume\ of\ a\ cone =\frac{62.8}{3}

                                        = 20.9 (Approx) cm³

Thus the volume of a cone is 20.9 cm³ .

Therefore the volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

x=20

The side lengths form a 345 triple

Step-by-step explanation:

345 triangles have 3, 4, and 5 as their lengths

If we divide all of them by 4 we get..

12/4=3 and 16/4=4 that means we are missing 5

Which system is equivalent to 3x squared - 4y squared = 25 over -6x squared -2y squared = 11
TEA [102]
So we are given the following system:
3x^2-4y^2=25\\&#10;-6x^2-2y^2=11\\\text{Multiply the second equation by -2:}\\12x^2+4y^2=-22\\\text{Add to the first equation we get:}\\15x^2=3&#10;\text{ therefore }x=\pm \sqrt{ \frac{1}{5} }
Using the first equation again we get:
3x^2-4y^2=25\\&#10;3x^2=4y^2+25\\&#10;x^2= \frac{1}{3}(4y^2+25)\\x^2= \frac{1}{3}(4 \frac{1}{5} +25)\\= \frac{43}{5}\\x=\pm \sqrt{ \frac{43}{5} }
