An object moves such that acceleration a(t)=2(1-3t). Given v(0)=-5 and x(0)=4, find x(1).


I know the answer is -1, just not too sure on how to get the work, thanks!

Answers

Answer:

x(1) = -1

Step-by-step explanation:

Given the equation for acceleration of the object as;

a(t)=2(1-3t)

a(t) = 2-6t

Integrate to get the velocity

v(t) = 2t-6t²/2 + C

v(t) = 2t-3t²+C

If v(0) = -5

when t = 0 v = -5

-5 = 2(0)-3(0)²+C

-5 = C

C = -5

v(t) = 2t-3t²-5

To get the displacement x(t), we will integrate the velocity function

x(t) = 2t²/2-3t³/3-5t+C

x(t) = t²-t³-5t+C

If x(0) = 4

At t = 0, x(t) = 4

4 = 0²-0³-5(0)+C

4 = C

C = 4

x(t) = t²-t³-5t+4

Get x(1)

x(1) = 1²-1³-5(1)+4

x(1) = 1-1-5+4

x(1) = -5+4

x(1) = -1

Hence x(1) = -1

What's ƒ(g(4)) if ƒ(x) = 3x2 – 3x + 6 and g(x) = 2x?

Answers

Answer:

Step-by-step explanation:

In order to do f(g(4)), we need to find what g(4) is in order to input it into the function f(x).

g(4) = 2(4) = 8

Now do f(8) because that's the value of g(4)

f(8) = 3(8^2) - 3(8) + 6 = 174

Over 20 years, the population of a town
decreased by 275 people to a population of
850. Write and solve an equation to find the
original population.

Answers

Answer:

p= 1125

Step-by-step explanation:

p-275= 850

p- 275= 850

  + 275  +275

p= 1125

P= the original population minus D= decrease in population is equal to C= the current population

p-d=c

Answer:

1125 people

Step-by-step explanation:

We don't know the exact quantity, but we know it has decreased by 275 and it's currently 850, so we will represent it like this:

x - 275 = 850

x = original amount of people

Now we just solve it like any equation

x = 850 + 275

x = 1125

Sam's two new aquariums each hold exactly 200 gallons of water. One aquarium will hold small fish and the other will hold large fish. Now he needs new fish for his aquariums.

•He will buy 5 small fish for every 10 gallons of water in the aquarium.
•He will buy 8 large fish for every 40 gallons of water in the aquarium.

What is the total number of fish Sam will have? What will be the ratio of Sam's small fish to large fish? Show or explain the steps you used to solve this problem.

Answers

In the 1st one he will have 100 small fishes. 200/10=20. 20x5=100
In the 2nd one he will have 40 large fishes. 200/40=5. 5x8=40
Sam will have a total of 140 fishes. 100+40=140

Step-by-step explanation:

* / = square root

You simply 2/72 which is 12/2, then simplify /8 which is 2/2.

You combine 2/2 and /2 which is 3/2.

The equation should be 12/2 over 3/2 so you simplify it which will give you 4.

(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)

A line is shown on a coordinate grid. The x-axis values are from negative 15 to positive 15 in increments of 3 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 12, 4, and 0, 0, and 12, negative 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to 6, negative 2 labeled as A, one leg is from 0, 0 to 0, negative 2, and the second leg is from 0, negative 2 to 6, negative 2.
