<em>Answer:</em>

<em>20 years</em>

<em>Step-by-step explanation:</em>

We can find the time it took to invest

Using the formula for calculating simple interest as shown

SI = PRT/100

Given

Principal P =  $600,000

SI = $39,000

Rate R = 3 1/4%

Required

Time

Substitute

39,000 = 600,000*13/400 * T

39,000 * 400 = 600,000*13 * T

15,600,000 = 7,800,000T

T = 15,600,000/7,800,000

T = 20

<em>Hence it took 20years for the sum invested to generate the interest</em>

sues teacher asked her to find 42.6 divided by 10 to the second power . how should sue move the decimal point to get the correct
Marizza181 [45]
She should move it one place to the left because there is one zero in ten so however many zeros there are in the multiple of 10 that's how many times you move it. Then, you move it left to divide and right to multiply. Hope I helped!

The electrical charge on a metal plate is given
Katarina [22]

Answer:

after 10 seconds  the charge  is 1.624

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

The electrical charge on a metal plate is given  by the function below, where t is the time in  seconds. What is the charge after 10 seconds?

C (t) = 12e^{\frac{-t}{5} }

My answer:

Given the information:

C (t) = 12e^{\frac{-t}{5} }  

when t =10 we have:

C (10) = 12e^{\frac{-10}{5} }

<=>  C (10) = 12e^{-2}

<=>  C (10) = 12\frac{1}{e^{2} }

<=> C (10) = 12 * 0.1353

<=>  C (10) = 1.624

Hence, after 10 seconds  the charge  is 1.624

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 4e2x - 3 - 5 = 0
Deffense [45]

Answer:

Value of x will be 0.1515

Step-by-step explanation:

We have given the equation 4e^{2x}-3-5=0

We have top fond the value of x using exponent and logarithmic property

So 4e^{2x}-3-5=0

4e^{2x}-8=0

4e^{2x}=8

e^{2x}=2

Taking log both side

lne^{2x}=ln2

2x=0.3010

x = 0.1515

Mathswatch Question! Mr Powers checks his electricity bill. Here are his meter readings. New reading: 6538 units, Old reading: 6
Setler79 [48]

Answer:

Cost = 284 x

Step-by-step explanation:

Given

Old = 6245\ units

New = 6538\ units

Required

The cost of units used

First, calculate the number of units used.

Units = New - Old

Units = 6538 - 6254

Units = 284

Next, multiply the units used by the cost per units,

Since the cost per unit is not given, we assume that it is x.

So, the total cost is:

Cost = Units * Cost\ per\ units

Cost = 284 * x

Cost = 284 x
