Answer:
Step-by-step explanation:
Given that:
As we know that the Parabola is of type
:
= -4a(y - ) where: is the origin of the line so we have:
and
<=> = -4a(y-20)
at y = 0, we have:
= -4a(0-20)
<=>
<=> x = ±
But we know that 2x= 80 <=> x= 40, so:
40 =
<=> 1600 = 80a
<=> a = 20
The equation for the parabola is:
It's height from the center at x= 0 => y= 20
Answer:
the answer is 3 over 18
Step-by-step explanation:
it is in statistics
T(1)=.46 sec
T(2)= 11.72 sec
Answer:
Step-by-step explanation:
y - 8 = -2(x - 6)
y - 8 = -2x + 12
y = -2x + 20
Are you sure this is written correctly? Any number whose digits add to 9 is divisible by 9. For a 2 digit number then, your choices are
18, 27, 36, 45, 54, 63, 72, and 81. None of these has the property that for the 2 digit number AB that B=2A-1. Solving your question algebraically is possible but you get fractional digits.
