Hello,
A)
h max
A:-2x/100+32/100=0==>x=16
B:-2x/100+18/100=0==>x=9
B)
y=0
A:-x²+32x+400=0==>x=41.612496... or x=-9.61... exclude
B:-x²+18x+500=0 ==> x=28.1039415...or x=-15.1039.. exclude
C)
x=0
A:y=4
B:y=5
D)-x²/100+32/100x+4=-x²/100+18/100x+5
==>14/100*x=1 ==>x=50/7=7.1428....
Check the picture below
radii are equal to each other, of course, and two tangent lines to the same circle, meeting outside, are also equal to in length
now, notice the middle line, is the same length for both triangles, because it's shared by both triangles, congruent triangles by SSS
Answer:
8 blocks because if you count it there are 8 boxes there
Answer:
They are parallel
Their slopes are equal
Y intercepts are different
System has no solution
