Answer:

y = 33.75 m/s.

Step-by-step explanation:

The graph of the rocket's velocity with respect to  time looks as follows :

y=0.15x^2 ...(1)

Where x is time in seconds

We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).

y=0.15\times (15)^2\\\\=33.75\ m/s

Hence, the speed of the rocket after 15 seconds is 33.75 m/s.

zmey [24]

Answer:

The probability of this occurring is 1/7

Step-by-step explanation:

Okay, here is a probability question.

From the question, we can identify the following;

Total number of socks = 2 + 4 + 2 = 8 socks

Since we are not given the order in which the socks was worn, we can assume any order.

Let’s say the right leg socks was worn first.

From the question, the socks on the right leg is a brown one.

So now let’s calculate the probability of selecting a brown socks out of the mix

That would be ;

number of brown socks/ total number of socks = 4/8 = 1/2

Now, for the left foot, we are having white sock here.

Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.

Now we need the probability of picking a white sock from the total 7. That would be ; 2/7

So the probability of both action occurring is simply the product of both probabilities and that is ;

1/2 * 2/7 = 1/7

Firlakuza [10]

Answer:

y=45x+25

Step-by-step explanation:

y=45x+25

25 is a one-time fee so it is at the end. 45 is the monthly fee so it goes in front of x.
