Answer:
78
Step-by-step explanation:
546 ÷ 7 = 78. So their is 78 blocks in each tower.
The area enclosed is (2x)(600-2x).(2x)(600−2x)=1200x−4x2
In order to maximize we need the derivative to be equal to 0.y′=1200−8x=0
1200=8x
x=150
Therefore the sides for maximum area are 150*300.

Answer:
(D) 59 MPH
Step-by-step explanation:
To do this, we simply must look at what the table is giving us. From the top left corner, we can see that they are supplying us with the mileage between each of the cities given. Since we're going from Dallas to Lubbock, find Dallas on the y-axis and go left until you see Lubbock.
The distance between Dallas and Lubbock is <u>351 miles</u>. Now, we have to take our given information, our desired travel time of <u>6 hours</u>, and divide from the miles to get our speed:

Then, we round up to the nearest whole number to get our answer of 59 miles per hour.
