What are the real zeros y=(x+3)^3+10?

igomit [66]

There is only 1
(x + 3)^3 + 10 = 0
(x + 3)^3 = - 10
(x + 3) = cuberoot(-10)
x = -3 + cuberoot(-10)

Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.

Allisa [31]

Answer:

Step-by-step explanation:

Given,

Number of red marble = 4
number of green marble = 3
number of transparent marble = 1
number of yellow marble = 3
number of orange marble = 3

Total number of marble except red and green = 3 +3+1

= 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

$n\ =\ ^7C_5$

$=\ \dfrac{7!}{(7-5)!.5!}$

$=\ \dfrac{7!}{5!.2!}$

$=\ \dfrac{42}{2}$

= 21

So, the required number of possible sets are 21.

If an arrow is shot upward on the moon with a velocity of 50 m/s, its height (in meters) after t seconds is given by H = 50t − 0

Luda [366]

Answer:

The velocity is: 48.34m/s

Step-by-step explanation:

Given

$u = 50m/s$ --- initial velocity

$h = 50t - 0.83t^2$

Required

The velocity after 1 second

We have:

$h = 50t - 0.83t^2$ and $t = 1$

Differentiate

$h' = 50 - 1.66t$

We have that:

$v = h'$

So, the equation becomes

$v = 50 - 1.66t$

Substitute 1 for t

$v = 50 - 1.66*1$

$v = 50 - 1.66$

$v = 48.34$
