Step-by-step explanation:
Answer:
this basically means that whenever x is increased then y will decrease, but if x is decreased y will increase.
Step-by-step explanation:
Answer:
#3 you are correct.
#4 you are correct.
Step-by-step explanation:
#3) Similar triangles have common ratio for all 3 sides.
AD=24 DB=27 EB=18
DB/AB = EB/CB
DB CB = EB AB
DB (CE+EB) = EB (AD+DB)
27(CE+18)=18(24+27)
CE=18(24+27)/27 - 18 = 16
#4) If the triangles are similar then their third sides are parallel
AD=15 DB=12 so AB=27
AE=10 EC=8 so AC=18
AC/EC = 18/10 = 9/4
AB/DB = 27/12 = 9/4
The triangles are similar, so BC || DE
Answer:
Volume of cylinder is 6285.71 square units.
Step-by-step explanation:
Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.
r=10 units
⇒ Diameter, d = 20 units
Also given height is twice its radius.
⇒ Height=2(r)=2(10)=20 units
<h2><em><u>Volume of cylinder=πr^2h</u></em></h2>
= 22/7 × 100×20
=22/7 × 2000
= 44000/7
= 6285.71square units.
hence, volume of cylinder is 6285.71 square units.
Ok, so what you're going to do is add the -6 to the other side and combine it with the number 2 making it 8, then you are going to subtract the 5k from the left side and add it to 3k so if you now have a -5k + 3k it would = -2k then you would take the 8=-2k and divide each side by -2 which leaves you with -4=k
