Ebony but a four year treasury note that pay the equivalent of 3.8% simple interest. She invested $3000 more in a 9 year bond e
Anastasy [175]

Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",

Let,

  • The amount invested in treasury note will be = x
  • The amount invested in bond will be = (x + 3000)

then,

→ \frac{x\times 4\times 3.8}{100} +\frac{(3000+x)\times 9\times 4.6}{100}=5204

→       \frac{15.2x}{100}+\frac{(3000+x)\times 41.4}{100} =5204

→         \frac{15.2x}{100} +\frac{124200+41.4x}{100} =5204

→            \frac{15.2 x+124200+41.4x}{100} = 5204

→               56.6x+124200=520400

→                               56.6x=520400-124200

→                               56.6x=396200

→                                      x = \frac{396200}{56.6}

→                                         = 7000

Amount invested in bond will be:

= x+3000

= 7000+3000

= 10000    

Thus the above is the correct answer.

What is the equation of the quadratic graph with a focus of (4,3) and a directrix of y=-6
Rufina [12.5K]

Answer:

f(x) = (1/18)x^2 - (4/9)x - 65/18

Step-by-step explanation:

Since the focus (4,3) is higher up than is the directrix y = -6, the vertex is between y = -6 and y = 3, halfway between these values, to be exact:  y = -3/2.  Thus, the y-coordinate of the vertex is (-6 + 3/2), or -4.5.  The x-coordinate of the vertex is 4, which comes from that 4 in (4,3).  Thus, the vertex is (4, -4.5) or (4, -4 1/2).

The standard equation for a vertical parabola with vertex at (h,k) is:

4p(y-k) = (x-h)^2, where p is the distance between vertex and focus or between vertex and directrix.  In this case p = 4.5.  Thus, the equation of this quadratic is 4(4.5)(y - [-4.5]) = (x - 4)^2, or

18(y+4.5) = (x-4)^2, or y+4.5 = (1/18)(x-4)^2.

Let's expand this and rewrite the result as a quadratic equation in standard form y = ax^2 + bx + c:

y + 4.5 = (1/18)(x^2 - 8x + 16).  Multiplying all terms by 18 to remove both fractions, we get:

18y + 81 = x^2 - 8x + 16.  Rearranging these terms, we get:

18y = x^2 - 8x + 16 - 81, or

18y = x^2 - 8x - 65, or

y = f(x) = (1/18)x^2 - (4/9)x - 65/18.
