mr_godi [17]

Answer:

an = 2(−4)^(n − 1); all integers where n ≥ 1

Step-by-step explanation:

The equation has the form ...

an = a1(r)^(n-1) . . . . . where a1 is the first term and r is the common ratio.

The first term is given as 2, and the ratio will be the ratio of the first two terms:

r = (-8)/(2) = -4

Terms are numbered starting with n=1, so the formula is ...

an = 2(-4)^(n-1) for n≥1

Ulleksa [173]

Answer:

9 inches

Step-by-step explanation:

The volume of a pyramid is given as:

$V = \frac{l* w*h}{3}$

where l = length of base of pyramid

w = width of base of pyramid

h = height of pyramid

The volume of the cylinder is already known ( $105 in^3$ ) and the other two dimensions are known as 5 in and 7 in.

From the formula of the volume of the pyramid, the height of the pyramid is given as:

$h = \frac{3V}{l*h}$

Hence, the height of the pyramid is:

$h = \frac{3 * 105}{5 * 7}\\ \\h = \frac{315}{35} = 9in$

The pyramid's height is 9 inches.
