The only thing that we have to do in this problem is to
convert the units.
We know that:
1000 g = 1 kg
100 cm = 1 m
Therefore:
density = (2.7 g / cm^3) * (1 kg / 1000 g) * (100 cm /
m)^3
<span>density = 2700 kg / m^3</span>

Step-by-step explanation:
Answer:
The length of the ramp must be at least 14.71 feet
Step-by-step explanation:
Given


<em>See attachment for complete figure</em>
Required
Length of the ramp (z)
To do this, we consider sin of angle A (
).
So, we have:

This gives:

Make z the subject



<em>The length of the ramp must be at least 14.71 feet</em>
Answer:
f(4) = 85 1/3 or 85.333...
Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) =
*
f(4) =
* 
Next, simplify the exponent:
f(4) =
* 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...
