5/12 - 4/5 = -23/60. You can't simplify -23/60. Hope this is right

A particle moves on a straight line and has acceleration a(t)=24t+2. Its position at time t=0 is s(0)=3 and its velocity at time

user100 [1]

Answer:

It's position at time t = 5 is 593.

Step-by-step explanation:

The velocity v(t) is the integral of the acceleration a(t)

The position s(t) is the integral of the velocity v(t)

We have that:

The acceleration is:

$a(t) = 24t + 2$

Velocity:

$v(t) = \int {a(t)} \, dt = \int {24t + 2} \, dt = 12t^{2} + 2t + K$

K is the initial velocity, that is v(0). Since V(0) = 13, K = 13

Then

$v(t) = 12t^{2} + 2t + 13$

Position:

$s(t) = \int {s(t)} \, dt = \int {12t^{2} + 2t + 13} \, dt = 4t^{3} + t^{2} + 13t + K$

Since s(0) = 3

$s(t) = 4t^{3} + t^{2} + 13t + 3$

What is its position at time t=5?

This is s(5).

$s(t) = 4t^{3} + t^{2} + 13t + 3$

$s(5) = 4*5^{3} + 5^{2} + 13*5 + 3$

$s(5) = 593$

It's position at time t = 5 is 593.

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = 2x - 7

y = -x + 5

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y</em>: 2x - 7 = -x + 5
[Addition Property of Equality] Isolate <em>x</em> terms: 3x - 7 = 5
[Addition Property of Equality] Isolate <em>x</em> term: 3x = 12
[Division Property of Equality] Isolate <em>x</em>: x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

Define original equation: y = -x + 5
Substitute in <em>x</em>: y = -4 + 5
Add: y = 1

-6a-4= -4 (1+7a) Solve for a.

soldi70 [24.7K]

Answer:

$a = 0$

Step-by-step explanation:

On the right side of the = multiply -4 through

$- 6a - 4 = - 4 - 28a$

add 28a and add 4 to both sides

$28a - 6a = 4 - 4$

$22a = 0$

divide both sides by 22

$a = 0$
