Find a polynomial f(x) of degree 4 that has the following zeros. 2, 5, 0, -7

Mathematics
1 answer:
Otrada [13]3 years ago

Answer:

Step-by-step explanation:

f(x) = (x - 2)(x - 5)x(x+ 7)

f(x) = (x^2 - 7x + 10)*x * (x + 7)

f(x) = x(x^3 - 39x + 70)

f(x) = x^4 - 39x^2 + 70x

To show that this is correct, I've made a graph with these points labeled. The graph is just around the x axis. The local maximums and minimums are just too large a value.

You inherit one hundred thousand dollars. You invest it all in three accounts for one year. The first account pays 4% compounded
77julia77 [94]
Let x = amount invested in the 1st account
      y = amount invested in the 2nd account
      z =  amount invested in the 3rd account

Because the total investment is $100,000, therefore
x + y + z = 100,000             (1)
Interest earned in one year from the accounts is $3,650, therefore
0.04x + 0.03y + 0.02z = 3,650
or
4x + 3y + 2z = 365,000      (2)

Because x = 5y, therefore obtain these 2 equations:
5y +y +z = 100,000
or
6y + z = 100,000          (3)
4*(5y) +3y + 2z = 365,000
or
23y + 2z = 365,000      (4)

Substitute z=1000,000 - 6y from (3) into (4).
23y + 2(100,000 - 6y) = 365,000
23y + 200,000 - 12y = 365,000
11y = 165,000
  y = $15,000
Therefore
  x = 5y = $75,000
  z = 100,000 - 6y = $10,000

Answer:
The amounts invested are
1st account: $75,000
2nd account: $15,000
3rd account: $10,000

How does the graph of g(x) = x+ 5 compare with the graph of the parent
vlada-n [284]

Answer:

C. The graph of g(x) is shifted 5 units up.

Step-by-step explanation:

The transformation shown shows a vertical translation.

f(x)=x\pm d\\\\\text{Vertical translation up/down 'd' units.}

The graph would move f(x) five units up.

Hope this helps.
