Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.
To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:
p '(t) = 2t + 5 = 0
Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.
Answer:
20m
Step-by-step explanation:
600 divided by 30 = 20
2 in 83628 is the tenths and 208 is the hundreds
CosB= 7/25
tanB= 24/7
sinB= 24/25
2 1/2 for $6.25 is the answer
