Answer:
2
Step-by-step explanation:
4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2. Please use
" ^ " to indicate exponentiation.
Rewrite 4x = 32 - x^2 in the standard form of a quadratic: x^2 + 4x - 32
Then the coefficients are a = 1, b = 4 and c = -32.
Find the discriminant. It is b^2-4ac.
Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.
Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.
So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."
Answer:
378 ft i think
Step-by-step explanation:
Number 6 is 10:10 The first plane arrives at 6:50 you add 50 minutes to that and keep adding 50 minutes until you get to after 10:00 because it says his plane arrived after 10:00.
Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,

4 inches of rain would fall in 6 hours
<h3><u>Solution:</u></h3>
Given that, A rain storm came through Clifton park
And it was accumulating 
inches of rain/hour
So amount of rain accumulated in 1 hour =
Thus amount of rain accumulated in six hours is calculated by multiplying the amount of water accumulating per hour and 6
Amount of water accumulated in 6 hours = Amount of water accumulated in 1 hour 
6
<em><u>Another way:</u></em>
Let "n" be the amount of rain accumulated in 6 hours
1 hour ⇒ rain accumulated
6 hours ⇒ "n"
By cross multiplication, we get
Hence, 4 inches of rain would fall in 6 hours.
