Answer:
4.2 ft
Step-by-step explanation:
Given the equation for the Law of Cosines, we can rewrite the equation to solve for "c" directly:
So the length of c is approximately 4.2 ft

Answer:
$3684
Step-by-step explanation:
The tax on the first $2000 is 0.02×$2000 = $40.
The tax on the next $9000 -2000 = $7000 is 0.05×$7000 = $350.
The tax on the next $70000 -9000 = $61000 is 0.054×$61000 = $3294.
Then the total tax due is $40 +350 +3294 = $3684.
The state income tax owed is $3684.
_____
<em>Additional comment</em>
For amounts over $9000, the tax owed can also be computed as ...
tax = (income × 0.054) - $96
which we consider to be a much simpler calculation.
Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).
