Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!
The answer to this question is y' = 10x^2 + 6. You have to use the power rule to bring the exponent down as a coefficient and then reduce the exponent by 1. Do it for all the terms using the sum rule for derivatives (derivative of a sum of the sum of its derivatives).
<h2><em>ts = 4x - 7
</em></h2><h2><em>
</em></h2><h2><em>sv = 5x - 15
</em></h2><h2><em>
</em></h2><h2><em>If s is the midpoint of ts and sv, then ts = sv, so
</em></h2><h2><em>
</em></h2><h2><em>4x - 7 = 5x - 15
</em></h2><h2><em>
</em></h2><h2><em>5x - 4x = 15 - 7
</em></h2><h2><em>
</em></h2><h2><em>x = 8
</em></h2><h2><em>
</em></h2><h2><u><em>Not 100% sure </em></u></h2>
It would probably be 1 and 3/8 yards of string left because if he cut 5/8 yards of the string it would be a subject of subtraction, so if you would subtract that amount from 2 yards, the answer would be 1 and 3/8 yards of string left, hope this helps, good luck
