Find the value of p and the value of q

vlabodo [156]

Answer:

p = 5 and q = -3

Step-by-step explanation:

nth term = pn^2 + qn where n is the sequence number.

first term = p + q = 2.....................(1)

2nd term = p(2)^2 + 2n = 14

4p + 2q = 14

2p + q = 7 .......................(2)

Subtract equations (2) -(1) :-

p = 7 - 2 = 5

and q = 2 - 5 = -3

sineoko [7]

Answer:

Option C. −4≤t≤−3

Step-by-step explanation:

we have

$H(t)=(t+3)^2+5$

This is the equation of a vertical parabola written in vertex form

The parabola open upward (the leading coefficient is positive)

The vertex is a minimum

The vertex is the point (-3,5)

The function is increasing in the interval [-3,∞)

The function is decreasing in the interval (-∞,-3]

The function will have a negative average rate when the function will be decreasing

therefore

the answer is option C
