Answer:
See below
Step-by-step explanation:
<em>Quadratic function is in general form of:</em>
- <em>y = ax^2 + bx + c</em>
<em>The function has a minimum if a > 0 and maximum if a < 0</em>
<em>The minimum or maximum point is a vertex of the graph</em>
- <em>A vertex is the point x = -b/2a</em>
<em>When b = 0, the min or max point equals to value of c.</em>
- 33. It has maximum of -1
- 34. It has minimum of 7
- 35. It has minimum at x = - 8/4 = -2
f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
- 36. It has maximum at x = -18/2(-3)= 3
g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
- 37. It has minimum at x = - 6/(2*3/2) = - 2
f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14
Answer: [D]: 98°<span> .
______________________________________
Explanation:
______________________________________
Since vertical angles are congruent;
and since </span><span>∠A and ∠B are vertical angles;
then: m</span>∡A = m∡B .
______________________________________
So given: m∡A = 98° ; then m∡B = 98° .

Answer:
Rate of snow fall per hour ≥ 1 inches per hour
Step-by-step explanation:
Given:
Amount of snow already settled = 4 inches
Time period of snow fall = 2 hour
New amount of snow = least 6 inches
Computation:
Extra amount of snow ≥ New amount of snow - Amount of snow already settled
Extra amount of snow ≥ 6 - 4
Extra amount of snow ≥ 2 inches
Rate of snow fall per hour ≥ Extra amount of snow / Time period of snow fall
Rate of snow fall per hour ≥ 2 / 2
Rate of snow fall per hour ≥ 1 inches per hour
the answer is 24
