Answer:

A powerful computer is purchased for $2000,

but on the average loses 20% of its value each  

year. How much will it be worth 4 years from

now?

The equation to use is:

y = abx . The initial

value

a = 2000 . In this case the value is

decreasing so multiplier b is always found by

subtracting the percent decrease from the

number "one," so  

b = 1! 0.2 = 0.8 . The time

is

x = 4 . Substituting into the equation and  

using a calculator for the calculations:

y = abx

= 2000(0.8)

4

= 819.2 . In four years

the computer will only be worth $819.20.

If two cylinder are similar and the ratio between the lengths of their edges is 4;3 what is the ratio of their volumes
Tems11 [23]

Answer:

64 : 27

Step-by-step explanation:

Given 2 similar figures with

ratio of lengths = a : b, then

ratio of volumes = a³ : b³

For 2 cylinders with ratio of lengths = 4 : 3, then

ratio of volumes = 4³ : 3³ = 64 : 27

4x + y =3<br> x + y - z = 9<br> 2x + 2y + z = 0
uranmaximum [27]

Answer:

[0, 3, -6]

Step-by-step explanation:

{4x + y = 3

{x + y - z = 9 ←

{2x + 2y + z = 0 ←

{4x + y = 3

{3x + 3y = 9 >> Combined equation

−¾[4x + y = 3]

{−3x - ¾y = −2¼ >> New Equation

{3x + 3y = 9

_________

2¼y = 6¾

___ ___

2¼ 2¼

y = 3 [Plug this back into all three equations to get the z-value of −6, and the x-value of 0]; 0 = x; -6 = z

I am joyous to assist you anytime.
