The position of a particle moving in a straight line at any time t is x(t) = 2t^2 + 6t + 5. What is the acceleration of the part

grandymaker [24]

Answer:

The acceleration of the particle at any time t

$a = 4\ m/s^{2}$

Step-by-step explanation:

Given:

The position of a particle moving in a straight line at any time t is.

$x(t) = 2t^{2} + 6t + 5$

The velocity of the particle $v = \frac{d(x)}{d(t)}$

$v = \frac{d}{d(t)}(2t^{2} + 6t + 5)$

$v= 2\times 2t + 6$

$v= 4t + 6$

So the velocity of the particle $v= (4t + 6)\ m/s$

The acceleration of the particle $a = \frac{d(v)}{d(t)}$

$a = \frac{d}{d(t)}(4t + 6)$

$a = 4\ m/s^{2}$

In this condition the acceleration does not depending upon the time, so the acceleration is constant

Therefore the acceleration of the particle at any time t $a = 4\ m/s^{2}$

Nimfa-mama [501]

Answer:

a = 5

Step-by-step explanation:

a +a+4 + 2a-3 = 21

4a +1 =21

The Population in Corpus Christi in 1970 was 204,525. The population in 2002 was 276,877. Create an

luda_lava [24]

Answer:

The population is 2017 is 291,254

Step-by-step explanation:

The exponential equation will be in the form

P = I( 1 + r)^t

where P is the present population

I is the population initially at 1970

r is the annual growth percentage

t is the number of years since 1970

So for 2002, we have

r in this case will be 2002-1970 = 32

277,877 = 204,525(1 + r)^32

(1 + r)^32 = 1.3586

1 + r = 1.0096

r = 1.0096-1

r = 0.0096

So the growth percentage is 0.96% annually

So the population in 2017 where t will be 2017-1970 = 37 will be

P = 204,525(1 + 0.0096)^37

P = 204,525(1.0096)^37

P = 291,254
