Finding a final amount in a word problem on exponential growth or decay
A principal of $3300 is invested at 8% interest, compounded annually. How much will the investment be worth after 9 years?
Use the calculator provided and round your answer to the nearest dollar.
Step-by-step explanation:
Use the formula for compound interest
f/p: f =p(1+i)^n
p = 3300
i =8% = 0.08
n = 9 years
A = p(1+r)^t
A = 3300(1+0.08)⁹
A = 3300× 1.99
A= 6596.71 dollar ~ 6597 dollar.

The table shows the heights of 10 randomly selected second-grade students.
Helght (Inches)
44 45 47 49 48 48 49 50 48 52
Based on the data, select the most reasonable prediction about the height of second-grade students.
O A. The typical second-grade student is less than 45 inches tall.
B. The typical second-grade student is about 45 inches tall.
C. The typical second-grade student is more than 50 inches tall.
D. The typical second-grade student is about 48 inches tall.
Answer:
Answer = D
Step-by-step explanation:
If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

The typical second-grade student is about 48 inches tall.
What is mean?'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'
According to the given problem,
Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }
Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52
= 480
Average of the given heights = [tex]\frac{480}{10}[/tex]
= 48
Hence, we can conclude, The typical second-grade student is about 48 inches tall since the average of the given data is 48.

Answer:
The center of the circle is at the coordinate: (1,6)
Explaination:
To find the answer all you need to do is add the x values together and divide by two and add the y values together and divide by two:
[tex]\frac{5-3}{2} =1[/tex] (x-values)
[tex]\frac{5+7}{2} =6[/tex] (y-values)
Therfore the center is at point (1,6)
Answer:
(1, 6 )
Step-by-step explanation:
The centre of the circle is at the midpoint of the diameter
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (5, 7) , then
midpoint = ( [tex]\frac{-3+5}{2}[/tex], [tex]\frac{5+7}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex], [tex]\frac{12}{2}[/tex] ) = (1, 6 )
The centre of the circle is (1, 6 )

[tex] \frac{ba}{ac} = \frac{h}{rt} [/tex]
solve for h
Answer:
Step-by-step explanation:
assuming that the triangles are similar, which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.
' = feet
" = inches
h / 20' = 4'-2" / 3'-4"
just use inches for this, it's easier
h / 240" = 50" / 40"
h = 240 ( 50 / 40 )
h = 300"
h = 25'
