maria [59]

Answer:

The 71st term is 428.

Step-by-step explanation:

Use Arithmetic Explicit formula:

f(n) = f(1) + (n - 1) d

Solve:

f(71) = 8 + (71 - 1) 6

f(71) = 8 + (70) 6

f(71) = 8 + 420

f(71) = 428

Select the solid whose cross sections are dilations of some two-dimensional shape using a point directly above the shape as a ce

s2008m [1.1K]

Answer:

Cone

Step-by-step explanation:

Options:

a) Cone b) Cube c) Cylinder d) Triangular prism

From the given options (a) to (d), option (a) is true.

This is so, because.

The volume (V) of a cone is:

$V_1 = \frac{1}{3}\pi r^2h$

This is as a result of dilating the cylinder by 1/3 whose volume is:

$V_2 = \pi r^2h$

In other words:

$V_1 = \frac{1}{3}V_2$

<em>i.e. the cross-section of the cylinder (V2) being dilated by 1/3 (which is between 0 and 1) gives the cone (V1)</em>
