Answer:
f = 3.1
Step-by-step explanation:
First you must subtract 6.4 from both sides to get -4.8f = -14.88. Divide both sides by -4.8 to get f = 3.1

Answer:
<em>Axis of symmetry line is parallel to y- axis</em>
Equation of the parabola <em> ( x - ( -2 ))² = (y - 12 ) </em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given equation is y = x²+4 x+16
y = x²+2 (2 ) x + (2)² - (2)² + 16
y = ( x + 2 )² + 12
( x + 2 )² = y - 12
<em> ( x - ( -2 ))² = (y - 12 ) </em>
( x- h)² = 4 a ( y - k)
<em> Center (h ,k) = ( -2 , 12)</em>
<em> Here 4 a = 1 </em>
<em> a = 1/4</em>
<em>Focus S = ( h , K +a) = ( -2 , 12 + 0.25) = ( -2 , 12.25)</em>
<em>Axis of symmetry line is parallel to y- axis</em>
To find the slope of the line, you need two points.
(-2 , 5) and (3 , -5)
5 - (-5) / -2 - 3
10 / -5 = -2
The slope of the line is -2. So your answer is C.
Ok so we know that in ONE second, the dam releases 40000 gallons of water. In ONE minute, there are 60 seconds. Therefore...
1 second----------------40000 gallons
60 seconds--------------? ( this is what we're trying to find.
To get from 1 to 60, we multiplied by 60. Now we do it on the other side. 40000 times 60 is 2,400,000, so the rate in gallons per minute is 2,400,000 gallons per minute
