Either the first or the third choice is correct. We can't tell which one without seeing the rest of the words ... the ones that are cut out of the picture.
Answer:
the amount due for 3 hours would be $52 + ($34/hr)(3 hrs) = $154
Step-by-step explanation:
Write two equations, one for the total cost payable to Water R Us and another to Clogs:
$52 + ($34/hr)t = $34 + ($40/hr)t, or
$18 = ($6/hr)t, which tells us that t = 3 (That's 3 hours).
At the time the charges from the two companies would be the same (3 hours into the job), the amount due for 3 hours would be
$52 + ($34/hr)(3 hrs) = $154
<span>Use the definition of continuity.
A function is continuous at a point x = a iff
lim [x → a] f(x) = f(a)
In other words, a function is continuous at a point if its value is equal to its limit at that point.
So, for f(x) to continuous at x = 4 we must have
lim f(x) = f(4)
x → 4
