The equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.
The total distance that Joe needs to cover to travel to Dallas = 320 miles {As he lives 320 miles away from Dallas}.
The distance that Joe covers after traveling for h hours at an average speed of 69 miles per hour = 69h {as Distance = Speed*Time}
Therefore, the distance left to cover by Joe, that is the distance from Dallas d can be written as the difference between the total distance needed to be covered and the distance Joe already covered.
Thus the equation is d = 320 - 69h.
Thus, the equation for the distance d from Dallas, in terms of h, the number of hours Joe has traveled is <u>d = 320 - 69h</u>. Hence, <u>option B</u> is the right choice.

I think the third one sorry if I’m wrong
Answer:
A = 0.859
Step-by-step explanation:
We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).
At y = 0, let's find x;
0 = xe^(x²)
Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.
So our upper band is x = 1
Thus,lets find the area;
A = ∫xe(x²) dx between 1 and 0
A = (e^(x²))/2 between 1 and 0
A = ((e¹)/2) - (e^(0))/2)
A = 1.359 - 0.5
A = 0.859
If it starts with 0.12 it is false.
But if it starts with 0.009 it is true.
No and 2/5 is the simplest form I hope I helped you
