You out a 7 with a little two at the top in the box
Remark
This problem is done in 2 steps. The first step determines k and the second step is your answer.
Determining K
P = 233 million
A = 231 million
k = ??
t = 1999 - 1991 = 8 years.
Solution
P = Ae^(kt)
233 = 231 * e ^(kt) Divide by 231
233/231 = e^(k8) Do the division
1.008658 = e^(k8) Take the log of both sides.
ln(1.008658) = k8 * ln(e) You are in natural logs. Ln(e) = 1; kt can be brought down and made into a result that is multiplied by ln(e)
ln(1.008658) = 8k Take the ln of 1.008 ...
0.008621 = 8k Divide by 8
k = 0.008621 / 8
k = 0.0011 rounded, but a more accurate number is in the storage area of the calculator.
Now to get the second part.
P = ??
A = 231
k = 0.0011
t = 12
P = 231 * e^(0.0011*12)
P = 231 * e^(0.012931114) using the stored value of M
P = 231 * 1.013015083
P = 234.006 which rounded to the closest million is 234 million
Answer 234 million.
X/y + 9 = n
x/y = n - 9
x = y(n -9)
y = x/(n - 9)
B is the correct answer
Answer:
106.6
Step-by-step explanation:
There is a triangle and rectangles inside of this shape. You need to split it up so you can find all the sides of the triangle and the squares. The attached image shows me doing that.
Now you need to calculate the area for all the rectangles and triangles.
The area of a triangle is A = bh / 2
The area of a rectangle is A = lw
The area of a square is A = s^2 or s * s.
Add up the area of all geometry together to get your answer.

10.2 is the area of the triangle
17.6 is the area of 4.4 by 4 rectangle
36.5 is the area of the 8.3 by 4.4 rectangle
42.3 is the area of the 8.3 by 5.1 rectangle.
The total area of the figure shown is ≈ 106.6
