(ASAPPP) The position of an object at time t is given by s(t) = -2 - 6t. Find the instantaneous velocity at t = 2 by finding the
prohojiy [21]

Answer:

The instantaneous velocity at t = 2 is -6.

Step-by-step explanation:

We have the position as the function

s(t) = -2 - 6t

As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.

so finding the derivate of  s(t) = -2 - 6t

∴ s'(t)=-6

The instantaneous velocity at t = 2

s'(2)=-6

Therefore, the instantaneous velocity at t = 2 is -6.

Please note that the negative value indicates the direction of movement, in this case, it would be backward.

Find the value of (3 + 4)2
elena55 [62]

Answer:

14

Step-by-step explanation:

We solve this by using 2 to open the bracket

(3+4)2 is the same as 2(3+4)

2(3)+2(4)

=6+8

=14

OR

(3+4)2 is the same as 2(3+4)

So we can solve the one inside the bracket first

=2(7)=14

The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacter
Drupady [299]

Answer:

  • f(x) = 50000*2^x
  • 3 days

Step-by-step explanation:

<u>Given:</u>

  • Initial amount of bacteria = 50000
  • Growth rate = 2 times a day

<u>Required equation:</u>

  • f(x) = 50000*2^x

<u>Solve for x:</u>

  • 400000 = 50000*2^x
  • 2^x = 400000/50000
  • 2^x = 8
  • 2^x = 2^3
  • x = 3

After 3 days bacteria numbers will reach 400000

Help please with this math question
Vanyuwa [196]
To solve this question, simply use the formula to find the volume of the cylinder,

V = Pi r^2 • h

V = 3.14 • 4^2 • 4.

Then compare the value for volume to the closest number on the number line. Is it in between 2 numbers, exactly one number on the number line or very close to one number as in the number line.
