Let f(x) = x^3 + 2x^2 + 3x + 1 and g(x)= 4x-5 Find f(x) x g(x)
Brums [2.3K]

▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪

Given :

f(x) =  {x}^{3}  + 2 {x}^{2}  + 3x + 1

g(x) = 4x - 5

let's solve for f(x) × g(x) :

( {x}^{3}  + 2x {}^{2}  + 3x + 1)(4x - 5)

4x {}^{4}  - 5 {x}^{3}  + 8 {x}^{3  }  - 10 {x}^{2}  + 12 {x}^{2}  - 15x + 4x - 5

4 {x}^{4}  + 3 {x}^{3}  + 2 {x}^{2}   - 11x - 5

therefore, correct choice is : D

The graph below shows the velocity f(t) of a runner during a certain time interval:
Jlenok [28]
For this case, the first thing we must do is take into account the definition of the axes:
 the x axis is time in seconds
 the y axis is velocity in meters per secon
 
 Then, we look for the cut point with the y axis, which is given by:
 (0, 2)
 This means that the initial speed is 2 m / s.
 
 We now look for the cut point with the x axis, which is given by:
 (8, 0)
 This means that the speed is 0 m / s, so the runner stopped when the time is 8 seconds.

 Answer:
 
The initial velocity of the runner was 2 m / s, and the runner stopped after 8 seconds.

I need help on 18 and 19 PLS HELP ME ILY I WILL MARRY U I WILL LOVEEE U FOR ETERNITY
Dmitriy789 [7]

Oof, this is surely a tough one.  But, if I'm looking at this correctly, than I think you were in the right mindset when trying to figure both of them out.  Like, for #18, think about the formula; P(B|A) = P(A and B)/P(A).  So, based on the question, you can let not rolling a 1 on the blue cube be A, and rolling a 1 on the red cube be B.  Now, personally, I prefer using the decimals when heading into the equations, but I'll convert the product into a fraction for the instruction's sake.  0.02777777778 + 0.13888888889 = 1/6.  1/6 ≈ 17.7%.  You can do the same for #19, the overall outcome would be 5/6, which would be about 83%.  Now, that's just me really attempting my hand at it, I will say, Math is far from my strong suite.  But, in all honesty, I really am doing my best to help (and no, it's not because of what you offered, lol, more rather I want to help people who struggle with the same problems I do).  Anyways, I hope this helps, and if you need more information, or anything, just let me know!  Wish ya the best of luck!!  ^u^
