25 in of rain in 2 weeks.
there are 14 days in 2 weeks
25/14 = 1.785 in per day
1.785 x 31 = 55.335 in. of rain
55.335 in of rain is your answer
hope this helps
Asa you start at the angel when it’s marked and then you move to the right. it’s simple when you understand.
Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.
<h3>
What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.

Answer:
-0.04x + 1100
Step-by-step explanation:
0.07x + 0.11(10,000-x) open bracket by multiplying by 0.11
= 0.07x + 1100 - 0.11x collect like terms
= 0.07x - 0.11x + 1100
= -0.04x + 1100
