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. $f(48.2)=\boxed{110.86}$

The polygon is built of 7 triangles (picture).

$P=7\cdot\dfrac{1}{2}ah\\
a=28.9 \text{ m}\\
h=30 \text{ m}\\\\
P=7\cdot\dfrac{1}{2}\cdot28.9\cdot30\\
P=3034.5 \text { m}^2 \Rightarrow C$
