Answer:
- y = 6 at x = 5
Step-by-step explanation:
It is assumed the question is about finding the minimum value as the given function has no maximum value, it is + ∞ as the coefficient of x² is positive
<u>The minimum/maximum value of a quadratic function is the vertex, which is at:</u>
- x = -b/2a
<u>For the given function y = x² -10x + 31, the vertex is:</u>
- x = - (-10)/2*1 = 10/2 = 5
<u>The value of y at this point is:</u>
- y = 5² - 10*5 + 31 = 25 - 50 + 31 = 6
<u>The point is </u>
- (5, 6)
Answer:
2.5 hours
Step-by-step explanation:
We are given that
Original height of candle=5 in
Every hour candle loses =8% of 5 in=0.4
According to question
Subtract 4 from both sides we get
Divide by 0.4 on both sides
x=2.5 hours
Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.
