What is the slant height of a regular pyramid if its lateral area is 160 units² and the perimeter of the base is 40 units?

SSSSS [86.1K]

Answer:

The slant height of a regular pyramid is $l=8\ units$

Step-by-step explanation:

we know that

The lateral area of a regular pyramid is equal to

$LA=\frac{1}{2}Pl$

where

LA is the lateral area

P is the perimeter of the base

l is the slant height

we have

$LA=160\ units^{2}$

$P=40\ units$

substitute in the formula and solve for l

$160=\frac{1}{2}(40)l$

$160=20l$

$l=160/20$

$l=8\ units$

Answer:

2000: 17.60 per pound
2010: 163.91 per pound
2025: 4,658.68 per pound

Step-by-step explanation:

We assume your formula is intended to be ...

p(t) = 17.6(1.25^t)

For t=0, ...

p(0) = 17.6

For t=10, ...

p(10) = 17.6·1.25^10 ≈ 163.91

For t=25, ...

p(25) = 17.6·1.25^25 ≈ 4,658.68
