Answer:
a) The unit rate of change of d with respect to t is equal to 1.6
b) the graph of the line in the attached figure.
Given:
551.88 + 341.64b
The coefficient of "B" is 341.64, the best statement that applies to it is:
<span>D. It is the cost for one cable box with DVR and HD service for one year.
</span>Cable boxes: $ 3.49 per cable box
HD Service: $ 9.99 per cable box
<span>DVR: <u> $ 14.99 per cable box</u>
</span>Total : $ 28.47
multiply <u> 12 months</u>
Annual cost $341.64
Lets factor this quadratic function
the factors are (tan x + cos x)(tan x + cos x)
So the answer is choice A.
Equal to the sum of the measures of the remote interior angles. (:
