<span>P(t) = Po(1 - r)^t

P(t) = price after t months --> S
Po = initial price -- P
r = rate as a decimal

S = P(.9)^4
-> = 100(.9)^4
-> = 65.61

(100 - 65.61)/100
34.39/100

Need help please on geometry

zimovet [89]

To solve this we are going to use the formula for the area of a circle: $A= \frac{1}{4} \pi d^2$
where
$A$ is the area of the circle
$d$ is the diameter of the circle

We know from our problem that the area of our circle is 10 inches long, so $d=10in$ . Lets replace that value in our formula to find $A$ :
$A=\frac{1}{4} \pi (10in)^2$
$A=78.54in^2$

We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.

If you drew a horizontal line on the coordinate plane, what could you say about the y-coordinate for every point on the line?

sattari [20]

It's the y intercept.
If y = a then every point on the line would be (x,a)
The lines slope is 0. I know that has nothing to do with the question, but it is true and it gives me 3 things to tell you.
