A posted speed limit of 55 mph means that: You may drive 55 mph only under favorable conditions.
<h3>What is the speed limit?</h3>
Speed limits on road traffic, as used basically to set the legal maximum speed at which vehicles are permitted to utilize on a given stretch of road.
Now generally, speed limits are normally indicated on traffic signs reflecting the maximum allowable speed in kilometers per hour (km/h) or eevn miles per hour (mph). They are primarily set by the legislative bodies of national or provincial governments and then enforced by law enforcement agencies. This suggests that speed limits varies from road to road and is even absent in some certain areas.
Now, in this question we are told that the posted speed limit is 55 mph. Thus, from our definitions of speed limits above it is clear that A posted speed limit of 55 mph means that: You may drive 55 mph only under favorable conditions.

Answer:
9
Step-by-step explanation:
As you know, 4 is between 3 and 10, so the middle definition applies.
f(4) = 4² -7 = 16 -7
f(4) = 9
Answer:
The base and height are both 8 cm.
Step-by-step explanation:
To find the area of a triangle, multiply the height and base, then divide this number by 2.
A = 
( <em>b</em> is the base, <em>h</em> is the height, and <em>A</em> is the area )
Since you're given only the area (rather than the base and height), follow the steps backwards, like so:
1. Multiply the area of the triangle by 2.
32 * 2 = 64
2. Since the question specifies that the two sides you're solving for are equal in length, the number you're solving for equals 64 when multiplied by itself. Set up an equation using this information (with <em>x</em> representing the length of the base and height) and solve:
x * x = 64
x² = 64
x = 
x = 8
