Answer:

At the end of 3 years, we could save upto $ 2975.4 with an interest rate of 3.3 %

Step-by-step explanation:

If we are putting $ 2700 into our IRA ( individual Retirement Account) for 3 years and we are earning 3.3% profit every year, we need to find the total amount saved at the end of 3 years.

Since the interest is calculated for more than 1 year, this is an example of compound interest.

The formula used is:

FV = P ( 1 + r/n) ^n^t

where FV = future value

P= Principal amount of money deposited

r= annual interest rate ( in decimal form)

n= number of times interest rate is compounded  (yearly)

t= time period

So for our given guestion:

P= $2,700

r = 3.3 % = 0.033

n= 1

t= 3

putting our values in the formula

FV = P ( 1 + r/n) ^n^t

FV = 2700 ( 1+ 0.033 / 1 ) ^ 1 ^* ^ 3

FV = 2700 (1.033) ^ 3

FV = 2975.4

So, at the end of 3 years, we could save upto $ 2975.4 with an interest rate of 3.3 %

Kent multiplies both sides of the equation below by an expression.
Korolek [52]
The steps below are presented in order to arrive to the value of k of the given equation. 
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,  
            (k + 12/ k)(k) = 8(k)

Then, we simplify,
             k + 12 = 8k
We then, subtract 8k to both sides of the equation,
           k - 8k + 12 = 8k - 8k

Simplifying,
                  -7k + 12 = 0

Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,                  
                     k = 12/7

Plot a graph for the following data recorded for an object falling from rest
shusha [124]
  1. The kind of curve obtained is linear.
  2. The relationship between the variables is direct variation.
  3. After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
  4. The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.

In this exercise, you're required to plot a graph for the data (velocity and time) recorded for an object that is falling from rest.

Based on the graph for the data (see attachment), we can logically deduce the following points:

  • The kind of curve obtained is linear.
  • The relationship between the variables is direct variation.
  • After 4.5 seconds, I expect the velocity to be equal to 140 ft/s.
  • The amount of time required for the object to attain a speed of 100 ft/s is 3.2 seconds.
