Answer:
(10,4)
Step-by-step explanation:
5 would change to 10 and 4 would stay
Answer:
Step-by-step explanation:
so the question is asking about the time from 1500 feet to 1100 feet. How long did they fall, w/o a parachute. aka "freefall" so, at 1500 feet the jumper is really at time zero. so, plug in to the formula
1100 = -16
+1500
( x represents seconds so i'll change it to t so we know it's time )
1100 = -16
+ 1500
now we can solve for t , to see how long the jumper falls
-400 = - 16 ( subtracting 1500 from both sides of equation )
25 = ( dividing both sides by -16 )
oh.. look at how nice that turns out.. :)
= t ( take the square root on both sides )
5 = t
the jumper fell for 5 seconds to get to 1100 feet
For this case we must find the product of the following expressions:
\frac {3x} {x + 1} * \frac {x} {x-7}
So:
\frac {3x ^ 2} {x ^ 2-7x + x-7} =\\\frac {3x ^ 2} {x ^ 2-6x-7}
So, we have to:
\frac {3x} {x + 1} * \frac {x} {x-7} = \frac {3x ^ 2} {x ^ 2-6x-7}
Answer:
\frac {3x ^ 2} {x ^ 2-6x-7}

<em>Answer:</em>
<em>x = 10</em>
<em>Step-by-step explanation:</em>
<em>Hi !</em>
<em>2(x - 3) = 14</em>
<em>2x - 6 = 14</em>
<em>2x = 14 + 6</em>
<em>2x = 20</em>
<em>x = 20 : 2</em>
<em>x = 10</em>
<em>Good luck !</em>
Answer:
B. Function 2
Step-by-step explanation:
Line P gradient is
Gradient = rise/run
= 1/4
Negative slope so gradient is - 1/4
Out of all the gradient, the lowest value has to be function 2 or line p & not 1/4r-5 because when r is 1 we get a gradient of 1.
-1/4xr - 5
-1/4x1 - 5
-1/4-5
-1/-1 = 1
Plus, 1 is greater than - 1/4 or - 0.25.
