V = (1/2)(13)(16)(12) cm^3
V = (1/2)(2,496) cm^3
V = 1248 cm^3
(10,5) (6,5) (10,5) (9,6). There is one remember this. One person(x) can’t have two birthdays. Two different people(y) can have the same birthday. Hope that helps
Answer: a = -5
Heyy, so with this question you would have to substiute 1 for x because normally the coordinates have x first then y. E.g. (x,y)
soo, f(1) = a(1)^2 +5
then, f(1) = a + 5
then equate to zero. E.g. a+5=0
then move over 5 to other side E.g. a=-5
soo.. yah.. pretty sure haha :)
