erastova [34]

Answer:

Step-by-step explanation:

Let x represent the number of spelling questions in the test.

Let y represent the number of vocabulary questions in the test.

Mrs morals wrote a test with 15 questions covering spelling and vocabulary. This means that

x + y = 15

Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100. This means that

5x + 10y = 100 - - - - - - - - - - - 1

Substituting x = 15 - y into equation 1, it becomes

5(15 - y) + 10y = 100

75 - 5y + 10y = 100

- 5y + 10y = 100 - 75

5y = 25

y = 25/5 = 5

x = 15 - y = 15 - 5 = 10

Derive the equation of the parabola with a focus at (-2,4) and a directrix of y=6 . Put the equation in standard form
Maru [420]

Answer:

y =  -  \frac{1}{4}  {(x + 2)}^{2}  + 5

Step-by-step explanation:

The vertex of this parabola is the midpoint of the focus (-2,4) and where the directrix intersects the axis of symmetry of the parabola (-2,6)

This parabola must open downwards due to the position of the directrix and has equation of the form:

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

where (h,k) is the vertex.

This implies that:

h =  - 2

and

k =  \frac{4 + 6}{2}  = 5

The value of p is the distance from the vertex to the focus:

p =  |6 - 5|  = 1

We substitute all the values into the formula to get:

(x -  - 2)^{2}  =  - 4(1){(y  - 5)}

{(x  + 2)}^{2}  =  - 4(y - 5)

Or

y =  -  \frac{1}{4}  {(x - 5)}^{2}  + 5
