Sample Answer: Juan will break even because 16 and –16 are a zero pair. –16 is the additive inverse o f 16 and the sum will be zero.

Hopefully, this helps! :D

Answer:

Yes. Juan will break even because 16 and -16 are a zero pair. -16 is the additive inverse of 16. So the sum will be 0.

If y = 4x3 + 4x and dx dt = 3, find dy dt when x = 2.
Eva8 [605]
Dy/dx = dy/dt / dx/dt

dy/dx = 12x^2 + 4 

when x = 2 , dydx = 52

52 = dy/dt / 3

so dy/dt =  156 (answer)

The diameter of this beach ball is 12 inches.
Wittaler [7]

Answer:

288π or 904.78

Step-by-step explanation:

We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is \frac{4}{3} × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.

Volume = \frac{4}{3} × π × r³

→ Let's substitute in the values

Volume = \frac{4}{3} × π × 6³

→ Simplify

Volume = \frac{4}{3} × π × 216

→ Simplify further

Volume = 288π or 904.78

For what values of k
sergey [27]

If y = cos(kt), then its first two derivatives are

y' = -k sin(kt)

y'' = -k² cos(kt)

Substituting y and y'' into 49y'' = -16y gives

-49k² cos(kt) = -15 cos(kt)

⇒   49k² = 15

⇒   k² = 15/49

⇒   k = ±√15/7

Note that both values of k give the same solution y = cos(√15/7 t) since cosine is even.
