Karen Gaines invested $10,000 in a money market account with an interest rate of 3.25% compounded semiannually. Three years later, Karen withdrew the full amount to put toward the down payment on a new house. How much did Karen withdraw from the account?
The total amount of money that Karen withdrew from her account three years later is $11,015.48.
How much did Karen withdraw?When an amount earns a compound interest seminannually, it means that the amount invested and interest accured increases in value twice a year.
The formula for calculating future value:
FV = P (1 + r)^nm
FV = Future value P = Present value R = interest rate m = number of compoundingN = number of years$10,000 x (1 + 0.0325/2)^6 = $11,015.48

[tex]\text{Given that,}~f(x)=x^3-2x^2\\\\f(i)=i^3-2i^2\\\\~~~~~~=i^2 \cdot i -2(-1)~~~~~;[i^2=-1]\\\\~~~~~~=-i+2\\\\~~~~~~=2-i[/tex]
The expression equivalent to f(i) is 2-i.
What is expression?The expression is mathematical statement which consist of variables, numbers and connected by at least one operation.
Given that, a function f(x) = x³ - 2x², we need to find the expression equivalent to f(i),
To find the same we will put x = i,
So,
f(i) = i³ - 2i² [i = √-1]
= (√-1)³ - 2(√-1)²
= -i - 2(-1)
= -i+2
= 2-i
Hence, the expression equivalent to f(i) is 2-i.

Josephine can correct her students' test papers in 9 hours, but if her teacher's assistant helps, it would take them 7 hours. How long, in hours and minutes, would it take the assistant to do it alone? (Write your answer in mixed units. Enter a zero in any unneeded blanks.)
Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.
What is the together rate?It is the sum of each separate rate.
In this problem, the rates are given as follows:
Josephine: 1/9.Assistant: 1/x.Together: 1/7.Hence:
[tex]\frac{1}{9} + \frac{1}{x} = \frac{1}{7}[/tex]
[tex]\frac{x + 9}{9x} = \frac{1}{7}[/tex]
[tex]9x = 7x + 63[/tex]
2x = 63
x = 31.5.

The height of a soccer ball in the air can be modeled by the equation h = -16t^2 +48f, where h is in feet of a ball that Cody kicks down the field.
How long is the ball in the air? (find the zeros).
What is the ball's max height? (find the vertex)
When will the ball reach its maximum height?
Answer:
3 seconds(0, 0), (3, 0)36 ft, (1.5, 36)Step-by-step explanation:
As the problem statement suggests, the question of time in the air can be answered by finding the zeros of the function. Similarly, the question of the ball's maximum height can be answered by finding the vertex. These findings are related by the fact that the vertex is on the line of symmetry, which passes through the midpoint between the zeros.
__
(a)The function can be factored as ...
h = -16t(t -3)
At any zero, one of the factors must be zero. (This is the "zero product rule.") The factors are zero for t=0 and for t=3.
The zeros are (0, 0) and (3, 0).
This tells you the height of the ball is zero initially (at t=0), and 3 seconds later (at t=3).
The ball is in the air for 3 seconds.
__
(b)The midpoint between the zeros is their average: (0 +3)/2 = 1.5. At that value of t, the ball will be at its maximum height.
The ball will reach its maximum height at t=1.5 seconds.
Using the above factored form to find the height, we get ...
h = -16(1.5)(1.5 -3) = 16(2.25) = 36 . . . feet
The ball's maximum height is 36 feet.
_____
Additional comment
The x-coordinate of the vertex of quadratic ax²+bx+c is found at the value ...
x = -b/(2a)
Here, that would be ...
t = -48/(2(-16)) = 3/2

The length of a rectangular garden is 9 feet longer than its width. If the garden's perimeter is 206 feet, what is the area of the garden in square feet?
Answer:
Area of rectangular garden is 2632 feet²Step-by-step explanation:
Given that length of Rectangular garden is 9 feet more than its width and perimeter of garden is 206 feet.
Let's assume length of Rectangular garden be x + 9 feet and width be x feet respectively. Firstly using the formula of Perimeter of rectangle we'll find the length and width of the garden.
[tex] \\ \\ \dashrightarrow \: \: { \underline { \boxed{ \pink{ \sf {Perimeter _{(rectangle)} = 2(L + W)}}}}} \\ \\ [/tex]
Substituting the required values:
[tex]\\[/tex]
[tex]\dashrightarrow \sf \: \: 2(x + 9 + x) = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 2x + 18 + 2x = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x + 18 = 206 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x = 206 - 18 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: 4x = 188 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: x = \dfrac{188}{4 } \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: x = 47 \\ \\ [/tex]
Hence,
Length of garden = x + 9 = 47 + 9 = 56 feetWidth of garden = x = 47 feet[tex]\\[/tex]
Now,
[tex] \\ \dashrightarrow \: \: { \underline { \boxed{ \pink{ \sf Area _{(rectangle)} = Length \times Width }}}} \\ \\ [/tex]
Substituting the required values:
[tex]\\[/tex]
[tex]\dashrightarrow \sf \: \: Area = 56 \times 47 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: Area = 2632~ ft^2 \\ \\ [/tex]
Hence,
Area of rectangular garden is 2632 feet²Answer:
Area of rectangular garden is 2632 feet²
Step-by-step explanation:
Given:-
Length of Rectangular garden is 9 feet more than its width perimeterof garden is 206 feet.To find :-
The area of rectangular gardenSolution:-
Let the length of Rectangular garden be x + 9 feet and width be x feet .
We know that , the formula of Perimeter of rectangle is 2 ( L + B )
putting the known values to find the dimensions ,
2 ( L + B ) = 206 feet
2 ( x + 9 + x ) = 206 feet
4 x + 18 = 206 feet
x = 47 feet
putting the values of x in the equation ,
Length :- 56 feet
width :- 47 feet
Now , area of rectangular garden :- L×B
Area => 56×47 feet²
Area => 2632 feet²

[tex]\displaystyle \frac{19}{5}[/tex]
3.8
The mean is 3.8.
Answer:
3.8 vitamins
Step-by-step explanation:
Step 1: Determine the mean of the data
The mean of the data is also known as the average of the data. We get this by adding up all of the values and dividing it by the amount of values that we have.
In this example, we have two points on the 1 marker, one point on the 3 marker, one point on the 5 marker, and one point on the 9 marker.
We add up all of the values, 1 + 1 + 3 + 5 + 9 and we get 19. We then divide the number of values that we have which is 5. So we do 19/5 and we get 3.8 vitamins is the mean.

Answer:
PA = 8 cm
Step-by-step explanation:
First, create a right triangle with legs OA and SA and hypotenuse OS. Use the Pythagorean Theorem to get the length of OS. Since this is a pythagorean triple (3-4-5) triangle, the hypotenuse is 5, meaning that OS is 5 cm long. Because OS and OP are both radii of the circle, they are equal. So, OP = 5 cm. Finally, simply add OA and OP to get PA:
OA + OP = PA
3 + 5 = PA
PA = 8 cm

Step-by-step explanation:
a Base side is 4cm
b Base side is 5cm
c Base side is 11cm
h Height is 3cm
I ran into a problem when inputing the c Base side. It won't allow me to go over 8cm, for some reason. But hold on. I found a solution! :)
a Base side is 4cm
b Base side is 5cm
c Base side is 8cm ← (Don't mind this, I'll explain it below.)
h Height is 3cm
With c Base side being 8cm, the result is [tex]A_L = 51[/tex]. This is clearly incorrect and is not supposed to be like that. But hold on! Let me explain what I did to fix the problem. Since 8cm was the maximum amount, I did this to fix the problem:
51 + 3 = 54 (9cm)
51 + 6 = 57 (10cm)
51 + 9 = 60 (11cm)

Step 1: Figure out how many years 2020 is after 1998
2020 is 22 years after 1998, therefore we should plug in 22 for x.
Step 2: Plug in known values
The only unknown variables in this equation are S and x. We just found out what x is, which leaves S for us to figure out by solving.
S - 1.5(22) = 5.1
Step 3: Solve
Now, all that's left to do is solve for S.
S - 1.5(22) = 5.1
S - 33 = 5.1
S = 38.1
