salantis [7]

Answer:

The answer is

<h2>4260 N</h2>

Step-by-step explanation:

The force acting on an object when given the mass and acceleration can be found by using the formula

<h3>Force = mass × acceleration</h3>

From the question

mass = 142 kg

acceleration = 30 m/s²

So we have

Force = 142 × 30

We have the final answer as

<h3>4260 N</h3>

Hope this helps you

A country is planning to decrease government spending in order to reduce the national debt. If the outlined changes are put into
SOVA2 [1]

<u>Answer</u>

Graph D represents the national debt of the country over the next years.

<u>Solution-</u>

The country's debt will decrease exponentially by one-third each year.

Current debt is $60 billion.

This problem can be treated as an exponential decay problem.

The general exponential decay function is,

y=a(r)^{-x}

Where,

a = initial value,

r = rate of change,

-ve sign of x represents the decrease in value of y as x increases.

Here, the rate of change is 3 as each year the debt becomes on third, and initial value of debt is $60, so

y=60(3)^{-x}

Plotting a graph taking number of year on x-axis and debt on y-axis, we can generate a graph for this function.

Putting different values of x, we can get the values of y. So the graph must have (0, 60), (1, 20), (2, 6.66), (3, 2.22), (4, 0.74), (5, 0.24) points on it.

Option B and C are incorrect, as they do not start from 60. (they don't have (0,60) on their curve)

Between option A and D, curve in D has all the points on it. So D is the correct graph.
