find the equation of a cubic function whose graph passes through points (3,0) and (1,4) and is tangent to x-axis at the origin
Tomtit [17]

Answer:

y = -2x^2(x - 3)

Step-by-step explanation:

<em><u>Preliminary Remark</u></em>

If a cubic is tangent to the x axis at 0,0

Then the equation must be related to y = a*x^2(x - h)

<em><u>(3,0)</u></em>

If the cubic goes through the point (3,0), then the equation will become

0 = a*3^2(3 - h)

0 = 9a (3 - h)

0 = 27a - 9ah

from which h = 3

<em><u>From the second point, we get</u></em>

4 = ax^2(x - 3)

4 = a(1)^2(1 - 3)

4 = a(-2)

a = 4 / - 2

a = -2

<em><u>Answer</u></em>

y = -2x^2(x - 3)

Hello can anyone please help me find the answer to this.
Law Incorporation [45]

Answer:

Step-by-step explanation:

No.  Starting out, Maria walks away from home at a constant speed (which we recognize because the graph is at first a straight line).  Then she stops  for  a little while, turns around and heads for home at the same speed as before (positively sloped graph), level graph, negatively sloped graph).

Please help me with 8, 9, and 10 thanks! Show work too
Harrizon [31]
In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.

8. hypotenuse / (short side) = 25/x = x/9
  x² = 25*9 = 5²×3²
  x = √(5²×3²) = 5*3 = 15

9. (long side) / (short side) = x/7 = 9/x
  x² = 7*9
  x = √(9*7) = 3√7

10. (short side) / (long side) = x/48 = 48/64
  x = 48²/64 = 36

stira [4]

Answer:

y=25

Step-by-step explanation:

y=4+4x+x^2

y=4+4(3)+(3)^2

y=4+12+(3)^2

y=4+12+(3x3)

y=4+12+(9)

y=16+9

y=25
