Answer:Rate of change of the surface area =876.85 square inches

Step-by-step explanation:

Surface area of a cylinder=2*pie*radius*height

Former radius and height are 8.0inches(15.5-7.5) and 46.5inches(33+13.5) respectively

New radius and height are 15.5inches and 33 inches respectively.(pie 22/7)

2*22*8*46.5=16368/7=2338.29

Also 2*22*15.5*33=22506/7=3215.14

Rate of change is 3215.14-2338.29=876.85inches

Why must one leg of a triangle that the Pythagorean triple represents need an even-numbered length?
pashok25 [27]

Most of the square numbers are even.so if we need to find root over we need an even number to convert it to perfect square.

See the example below

  • P=3
  • B=4
  • H=5

\\ \ast\bull\rm\longmapsto H^2=P^2+B^2

\\ \ast\bull\rm\longmapsto H^2=3^2+4^2

\\ \ast\bull\rm\longmapsto H^2=9+16

\\ \ast\bull\rm\longmapsto H^2=25

\\ \ast\bull\rm\longmapsto H=\sqrt{25}

\\ \ast\bull\rm\longmapsto H=5

Some other triplets are

  • (6,8,10)
  • (5,12,13)
  • (8,15,17)

Solve each equation for the ind<br>2. 2(x-7)=10​
SVETLANKA909090 [29]

Answer:

x= 12

Step-by-step explanation:

2(x-7) = 10

Distribute the 2. 2x-14 = 10

Add the 14 onto both sides to cancel it out on the original side and following the rules- the same must be done to the other side. 2x-14 (+14) = 10+14 -----> 2x = 24

Divide both sides by 2 to get the X alone. 2x/2 = 24/2 ---------> x= 12
