Derive the equation of the parabola with a focus at (−7, 5) and a directrix of y = −11. f(x) = one thirty second(x + 7)2 − 3
f(x) = −one thirty second(x + 7)2 − 3
f(x) = −one thirty second(x − 7)2 − 3
f(x) = one thirty second(x − 7)2 − 3

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

your answer would be 12

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
