Your computer monitor has a width of 14.98 inches and a height of 11.24 inches. What is the area of the monitor display in squar
1 answer:
It is given in the question that your computer monitor has a width of 14.98 inches and a height of 11.24 inches.
And we have to find the area of the monitor display in square meters.
And the formula of area is width times height .
SO to find the area, we have to multiply the given width and height.That is
And now we need to convert square inches to square meters and for that we have to multiply the given answer by 0.00064516. That is

To see how much interest she'll get after a quarter:
$4132.79 + ($4132.79 × 0.048) = $4331.16
After two quarters:
$4331.16 + ($4331.16 × 0.048) = $4359.06
You can keep going until eventually reaching $8000 then see how many quarters has passed. That's a lot of calculator work!
There's another way that uses less calculation, but more algebra. I call it the exponential formula method! There's this general formula for stuff that increases exponentially, like virus, population, and MONEY:
M is money, d is deposit, t is time taken, and c is just some unknown constant related to the interest rate. There's also the natural logarithm form of this equation, which will come in handy later:
Alright first we gotta find that constant c for this equation to be useful! Let's plug in stuff we know.
We know how much she'll have after one quarter (0.25 years), and we know how much she deposited initially.
After pressing some buttons on the calculator we'll find that c = 0.1875.
Great! Now we can use that formula to find how many years (t) it'll take to reach M=$8000. To save time I'm going to use the natural log form:
That will give us t = 3.522 which means it'll take approximately 3.5 years for her deposit to reach $8000!
$4132.79 + ($4132.79 × 0.048) = $4331.16
After two quarters:
$4331.16 + ($4331.16 × 0.048) = $4359.06
