Answer:

12750

Step-by-step explanation:

The sequence of visitors is

50, 100, 200, 400, .....

This is a geometric sequence

with common ratio r = 2

The sum to n terms is found using

$S_{n}$ = $\frac{a(r^n-1)}{r-1}$ ( a is the first term )

$S_{8}$ = $\frac{50(2^8-1}{2-1}$ = 50 × 255 = 12750

The distance traveled (in feet) by the three-toed sloth can be modeled by f(s) =2.3s, where s is the time in minutes. Find the d

Mice21 [21]

$\huge{\boxed{\text{110.86 feet}}}$

We know that $f(s)=2.3s$ and $s=48.2$

Substitute in the value. $f(48.2)=2.3*48.2$

Use a calculator to multiply. $f(48.2)=\boxed{110.86}$
