Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4
lora16 [44]

Answer:

option A.) y-3 = 1/16 (x-2)^2

Step-by-step explanation:

we know that

If the axis of symmetry is parallel to the y-axis, then we have a vertical parabola

The equation of a vertical parabola is equal to

4p(y-k)=(x-h)^{2}

where

(h,k) is the vertex

In this problem we have

(h,k)=(2,3)

p=4

substitute

4(4)(y-3)=4(4)(x-2)^{2}

16(y-3)=(x-2)^{2}

(y-3)=(1/16)(x-2)^{2}

Maria Addai has been offered a future payment of $990 two years from now. If she can earn 8.2 percent compounded annually on her
IgorLugansk [536]

Answer:

845.6306

Step-by-step explanation:

Firstly this is annuity based

Let, investment at beginning of year = <em>x</em>

Then value at year 1 end = x + (8.2% \times x)

Value at end of year 2 = (x + 0.082x) + (8.2% \times (x + 0.082x))

Now this value = $990

Therefore,

990 =  (x + 0.082x) + ((x + 0.082x) \times 8.2%)

990 = x + 0.082x + 0.082x + 0.006724x = 1.170724x

x = 990/1.170724 = 845.6306
