Answer:

$45950.57

Step-by-step explanation:

We have been given that the Laffite family deposits $8500 in a savings account at 6.75% interest, compounded continuously.

To find the amount in the account after 25 years we will use continuous compounded interest formula.

A=P*e^{rt},where,

A = Final amount after t years,

P = Principal amount,

e = Mathematical constant,

r = Interest rate in decimal form,

t = Time.

Let us convert our given rate in decimal form.

6.75\%=\frac{6.75}{100}=0.0675

Upon substituting our given values in above formula we will get,

A=\$8500*e^{0.0675*25}  

A=\$8500*e^{1.6875}  

A=\$8500*5.405948925141167

A=\$45950.5658636999195\approx\$45950.57  

Therefore, there will be $45950.57 in the account after 25 years.

With compounded continuously the formula is
A=pe^rt
A future value?
P present value 8500
R interest rate 0.0675
T time 25 years
E constant

A=8,500×e^(0.0675×25)
A=45,950.57

you can buy 5 cans of green beans at the village market for $3 you can buy 10 of the same cans of beans at Sams Club for $6.10 w
ioda

Each can of green beans costs  ($3.00/5) = 60¢  at the
village market, and  ($6.10/10) = 61¢  at Sam's Club.

If you're watching every penny, then that MIGHT be enough
of a difference to make you decide to buy your beans at the
village market, but not necessarily.

If, say, the village market is farther away from you, or if there are
other things you're going to get from Sam's anyway, then you
should buy your beans there too.

The data in the table can be entered into a calculator to determine a linear equation of best fit where x represents the number
Yakvenalex [24]

Based on the data given, the conclusion that can be drawn from the correlation coefficient associated with the linear equation is C. There's a weak negative correlation between the variables.

<h3>How to illustrate the information?</h3>

From the information given, it can be seen that the value of y is increasing with the increase in the value of x.

This implies that the correlation is positive. Also, the change in the values of y with x are scattered a lot.

Therefore, the conclusion that can be drawn from the correlation coefficient associated with the linear equation is that there's a weak negative correlation between the variables

A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began.
jenyasd209 [6]

The equation that models this situation is z = 7.9y + 12.

A linear equation is a function that has a single variable raised to the power of 1.  An example is x = 4y + 2.

Where:

  • 2 is the constant
  • x = dependent variable
  • y = independent variable  

From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.

z = 7.9y + 12

Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.
