Any geometric sequence can be expressed as:
a(n)=ar^(n-1), in this case a=64 and r=1/2 so
a(n)=64(1/2)^(n-1)
So the 2nd, 3rd, and 4th terms are:
32, 16, and 8
Answer:
-10
Step-by-step explanation:
g(5) for g(x)= -2x
we put 5 to x
g(5) = -2.5
=-10
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y
By Pythagoras’ theorem,
BD square= AB square + BC square
BD square= 3.15 square + 1.77 square
BD Square=13.0554
BD= square root 13.0554
BD=3.61 (to 3sf)
