C.24 is supplementary to 7
She must start out going 8 miles per hour until the time elapsed is 1 hour at which time she drops 1.5 miles per hour. The same happens again in the second hour and the third.
The graph must have hours on the x axis and speed on the y axis.
The starting point is (0,8)
The graph must be
y = 8 - 1.5x
You need three points.
x y
0 8
1 6.5
2 5
She earns ($9.70x40) for a 40 hour week=$388
She earned $489.85-$388 extra= $101.85
She gets paid $9.7x1.5 for every extra hour=$14.55
She worked $101.85/$14.55 hours extra=7hours
She worked 7+40 hours that week=47 hours
E^(∞): This is defined as 'e' being raised to a huge value. Hence the result will definitely be a large number which is also infinity (∞), i.e. e^(∞) = ∞.
e^(- ∞) = 1/e^(∞) = 1/∞ = 0.
36 is the answer you are looking for.
