Allushta [10]

Answer:

Step-by-step explanation:

Part A

To keep it simple, I will use v instead of vi, x instead of triangle x and t instead of triangle t.

The equation becomes: x = vt + 1/2at^2

Solve for a:

x = vt + 1/2at^2

x - vt = 1/2at^2

(x - vt)*(2/t^2) = 1/2at^2*(2/t^2) = a

a = 2(x-vt)/t^2

or writing in the right format

a = 2(Δx - viΔt) / Δt^2

How much did you invest if you earned $131.60 in interest at a rate of 4% for seven years?

Ket [755]

The amount invested is $ 470

<h3><u>Solution:</u></h3>

Given that , we have earned $131.60 as simple interest for an amount deposit at the rate of 4% for seven years.

We have to find the amount invested. That is, we need to find the principal sum

Let us use the simple interest formula

<em><u>The simple interest is given as:</u></em>

$\text { Simple interest }=\frac{p r i n c i p a l \times \text {rate of interest } \times \text {number of years}}{100}$

Here, simple interest = $ 131.60

Rate of interest = 4 %

Number of years = 7

principal = ?

Substituting the values in formula, we get

$\begin{array}{l}{131.6=\frac{\text { principal } \times 4 \times 7}{100}} \\\\ {131.6 \times 100=\text { principal } \times 4 \times 7} \\\\ {13160=\text {principal } \times 28} \\\\ {\text {Principal }=470}\end{array}$

Thus the amount invested is $ 470
