Answer:
5 feet per second
Step-by-step explanation:
Given that,
X(seconds) 0 1 2 3 4
Y (feet) 0 1 4 9 16
We need to find the average rate of change between 1 seconds and 4 second.
X = 4-1 = 3 seconds
Y = 16 - 1 = 15 feet
We know that,
Speed = distance/time
So,
So, the correct option is (c).
Answer:
1
Step-by-step explanation:
Given function:
y = px² - 4x + q
To find the points of maxima or minima
= 0
or
2px - 4 + 0 = 0
or
px = 2
or
x = [2 ÷ p]
at p = 2
x = 2 ÷ 2 = 1
To check for minima
> 0
thus,
2p - 0 > 0
2p > 0
for positive value of p function is minimum at x = 1
2) at q = 5 also x = 1 as value of x is independent of q
