What’s the next three numbers after 1, -3.9,27

Mathematics
1 answer:
4vir4ik [10]3 years ago
4 0

Answer:

-105.3,729,-2843.1

Step-by-step explanation:

so I ruled out addition and subtraction cause it's not decreasing or increasing regularly

so I considered division and multiplication

where I did the latter over the former

3.9/1= -39/10 and 27/-3.9=-90/13

so I used the two to form an alternating pattern

27×{-39/10}= -105.3

-105.3×{-90/13}= 729

729×{-39/10}= -2843.1

A 40-m-long chain hangs vertically from a cylinder attached to a winch. Assume there is no friction in the system and the chain
daser333 [38]

Answer:

a) W₁ = 78400 [J]

b)Wt = 82320 [J]  

Step-by-step explanation:

a) W = ∫ f*dl      general expression for work

If we have a chain with density of 10 Kg/m, distributed weight would be

9.8 m/s² * 10 kg   = mg

Total length of th chain is 40 m, and the function of y at any time is

f(y) = (40 - y ) mg   where ( 40 - y ) is te length of chain to be winded

At the beggining we have to wind 40 meters   y = 0 at the end of the proccess  y = 40 and there is nothing to wind then:

f(y) = mg* (40 - y )

W₁ =  ∫f(y) * dy    ⇒ W₁ = ∫₀⁴⁰ mg* (40 - y ) dy  ⇒ W₁ = mg [ ∫₀⁴⁰ 40dy - ∫₀⁴⁰ ydy

W₁ = mg [ 40*y |₀⁴⁰   -  1/2 * y²  |₀⁴⁰    ⇒  W₁ = mg* [ 40*40 - 1/2 (40)² ]

W₁ = mg * [1/2]     W₁ = 10*9,8* ( 800 )

W₁ = 78400 [J]

b) Now we can calculate work to do if we have a 25 block and the chain is weightless

W₂ = ∫ mg* dy     ⇒    W₂  = ∫₀⁴⁰ mg*dy   ⇒    W₂  = mg y |₀⁴⁰

W₂ = mg* 40   = 10*9.8* 40  

W₂ = 3920 [J]

Total work

Wt = W₁  +  W₂        ⇒    Wt = 78400 + 3920

Wt = 82320 [J]

Select the statements that are true for the graph of y=(x+2)^2+4
likoan [24]
Alrigty

in form
y=a(x-h)^2+k
the vertex is (h,k)
the constant, a, deterimines the size and direction
if a>0, then the parabola opens up and the vertex is the minimum
if a<0 then the parabola opens down and the vertex is the maximum

so we are given
y=1(x-(-2))^2+4
1>0 so it opens up
vertex is (-2,4)
the vertex is a minimum


the vertex is (-2,4) and the graph has a minimum

The first three terms in a pattern are shown in the image below. How many circles would be in the 5th term?
Alex Ar [27]

Answer:

15

Step-by-step explanation:

the pattern is like this

start with 1 then add 2 equals 3

start with 3 then add 3 equals 6

so 6 add 4 equals to 10

and the 5th term will be 10 add 5

equals to 15
