Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = −1. (2 points)

Mathematics

The focus is above the directrix, so the parabola opens upward—its vertical scale factor is positive (+1/12). The line of symmetry is x=-5, so the vertex form of the equation will have the factor (x -(-5))² = (x+5)². The choice that meets both these requirements is
  D. f(x) = (1/12)(x + 5)² + 2

bazaltina [42]

Answer:

x=3

y=5

Step-by-step explanation:

x+5y=28 (i)

-x-2y=-13. (ii)

add equation 2 from equation 1

x+5y=28

-x-2y=-13

3y=15

y=5

put the value of y in equation 1

x+5y=28

x+5*5=28

x+25=28

x=28-25

x=3

zloy xaker [14]

Answer:

15.32

Step-by-step explanation:

Eleven and seven-hundredths =11+\frac{7}{100}

(Here, \frac{1}{100} denotes the hundredth)

Four and twenty-five hundredth =4+\frac{25}{100}

Therefore,

Sum of Eleven and seven-hundredths added to four and twenty-five hundredth = 11+\frac{7}{100}+4+\frac{25}{100}

=15+\frac{32}{100}

=15+0.32

=15.32
