Answer:
15 units
Step-by-step explanation:
ΔABC is right with ∠C = 90° and AB the hypotenuse
using Pythagoras' identity on the triangle
AB² = AC² + BC² , hence
BC² = AB² - AC² = 17² - 8² = 289 - 64 = 225
⇒BC = = 15 units

Explanation:
a) see the attachment for a graph (red curve)
__
b) The piecewise defined function can be ...
__
c) The new cost function is ...
The charge is a flat $10 for any period up to 5 hours, then $1 per additional hour after that, prorated for partial hours. There is apparently no upper limit on parking time as there was with the original function. (The graph shown goes beyond 15 hours; the domain of the original C(x) is 0 to 12 hours.) For reference, the new cost structure is shown in blue in the attachment.
_____
<em>Additional comment</em>
Under the new structure, costs are significantly higher for short-term parking, and lower once the term exceeds 6 hours.
Answer:
2,592 square cm.
Step-by-step explanation:
It is given that the dimensions of rectangle A are four times the dimensions of rectangle B.
Let dimensions of rectangle B are l×b.
So, the dimensions of rectangle A are 4l×4b.
Area of rectangle is
Area of rectangle B is
The area of rectangle B is 162 square cm.
Area of rectangle A is
Therefore, the area of rectangle A is 2,592 square cm.
