Answer:
y=3/10;X=-7/10
Step-by-step explanation:
put y=x+1 into where you find y.
solve for X which is -7/10
and put -7/10 into the second equation and solve for y. which is also =3/10
Volume=height times area of base
area of base=pi times r^2
volume=(h)(pi)(r^2)
diameter=2r
diameger=8
8=2r
divide 2
4=r
h=3 times r
h=3r
r=4
h=3(4)
h=12
r=4
h=12
pi=3.14
subsitute
volume=(12)(3.14)(4^2)
volume=(12)(3.14)(16)
volume=602.88 in^3
With intersecting chord lengths multiplying the 2 given lengths of one chord needs to equal the multiplication of the 2 lengths of the 2nd chord
so on chord FH you have 3.5 and 4.8
multiply those: 3.5 x 4.8 = 16.8
so now chord GI needs to equal 16.8
to find Y divide 16.8 by 2.4
y = 16.8 / 2.4 = 7
y = 7
Answer:
B6es
Step-by-step explanation:
Step-by-step explanation: 8x+2y=0 move variabe to the right
next divide both sides by 2 and that gives you 2y =-8x to get the answer that is y= -4x
