Answer:
15u^3 + 8u^2 - 6u + 13
Step-by-step explanation:
(7u^3 + 8u^2 + 8) + (8u^3 - 6u + 5)
= 7u^3 + 8u^2 + 8 + 8u^3 - 6u + 5
= 7u^3 + 8u^3 + 8u^2 - 6u + 5 + 8
*Now add the like terms
= 15u^3 + 8u^2 - 6u + 13
And that is all your can do!
Answer:
0.2 seconds
Step-by-step explanation:
The graph of b(t) = -16t^2 + 5t + 15 is a parabola opening downward. The maximum value of b(t) occurs at the vertex. The t-coordinate of the vertex is t = -5 / (2(-16)) = 5/32 = 0.15625 sec ≈ 0.2 sec.
Answer: a = 8
Step-by-step explanation:
use the equation a^2 + b^2 = c^2
c = 17, b = 15
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a = 8
