Suppose that you have $6,000 to invest. Which investment yields the greater return over a 10 year period: 7.44% compounded daily

Nikitich [7]

Hi
Here is you answer mate
But don’t forget to mark me the brainliest

Plug the applicable numbers into the compound interest formula and see which is more.
A = p(1+r/n)nt
A = future amount
p =principal investment
r = interest rate as a decimal
n = number times compounded per year
t = time in years

A = 5000(1+.0743/365)365(10)
= 5000(1.000203562)3650 = $10,510.38

A = 5000(1+.075/4)4(10)
= 5000(1.01875)40 = $10,511.75

As you can see these are practically equal, but the 7.5% quarterly is more.

The table below shows selected points from a function.

FrozenT [24]

Answer:

True

Step-by-step explanation:

Rate Of Change Of Functions

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

$\displaystyle m=\frac{d-b}{c-a}$

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

$\displaystyle m=\frac{4-1}{2-1}=3$

Now, we use the second and the third point (2,4) (3,9)

$\displaystyle m=\frac{9-4}{3-2}=5$

This difference in values of the slope is enough to state the function is non-linear
