$6,000 for 6 years at 8½% compounded daily will grow to ?
iren [92.7K]

When an amount P  is invested for t years during which it earns an interest of r dollars compounded  m times per year, the formula to calculate the amount that investment grows to after t years is,

A=P(1+\tfrac{r}{m})^{mt}.

Assuming that a years has 365 days ,the values for each of these variables is given as follows, m=365 ,t=6r=8.5\%=0.085 . The value of the investment after 6 years is then calculated as shown below,

A=P(1+\tfrac{r}{m})^{mt}\\A=6000(1+\tfrac{0.085}{365})^{(365\times 6)}\\A=9991.15

The investment grows to reach  $9991.15 in 6 years.

Find the equation of the line in slope intercept form that has a slope of -2 and passes through the point (6,3). Demonstrate tha
DanielleElmas [232]

Answer:

y=-2x+15

Step-by-step explanation:

First, write out the equation in slope-intercept form, with what you already have:

y=-2x+b

Let "b" represent the y-intercept.

To find the y-intercept, substitute the point (6,3) in for the "x" and "y" variable of the equation and solve for "b":

3=-2(6)+b\\3=-12+b\\3+12=-12+12+b\\15=b

Therefore, your y-intercept is 15.

That means your equation is slope-intercept form <em>is</em> y=-2x+15.
