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....
It would probably be 675 cause i did it and got that
Answer:
B
Step-by-step explanation:
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:
When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
The answer is y=-x+3
Therefore the slope is -1
The y intercept is 3
