Determine the compound interest earned on $200 invested at 3.25% compound annually for 6 years
Answers
Answer:
$882.24 compound interest earned / $1,082.24 total
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
[tex]P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate
n = number of times compounded annually
t = time
Now lets plug in the values into the equation.
[tex]200(1+\frac{.325}{1} )^{6}[/tex] = 1,082.24
Since we want to know the compound interest earned, just subtract 200 from 1,082.24.
1,082.24 - 200 = $882.24
Mrs. Alexander wants to make a rectangular quilt that will have an area of 80 square feet So far, she has made 16
squares for the quilt each 2 feet long and 2 feet wide. Does she have enough squares to complete the quilt?
Answers
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.
Step-by-step explanation:
The given is,
Area of an rectangular quilt - 80 square feet
She made 16 squares
Square have 2 feet long and 2 feet wide
Step:1
Area of rectangular quilt = 80 square feet
Area of 16 squares = 16 × Area of square..................(1)
Formula for area of square,
[tex]A = a^{2}[/tex]................................(2)
Where, a - Sides of square
a = Length = Wide
From given,
a = 2 feet
Equation (2) becomes,
[tex]A = 2^{2}[/tex]
A = 4 square feet
Equation (1) becomes,
Area of 16 squares = 16 × 4
= 64 square meters
Area of rectangular quilt ≠ Area of 16 squares
80 ≠ 64
Area of square is less compare to area rectangular quilt, so we need more square,
Required amount of square area = 80 - 64
= 16 square feet
Required amount of squares = [tex]\frac{16}{4}[/tex]
= 4 squares
Total(16+4) square areas = 20 × 4 = 80 square feet
Area of rectangular quilt = Area of 20 squares
80 square feet = 80 square feet
Result:
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.

What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Given function, y = 3x²+7x+2
Compare the given function to f(x) = ax² + b x + c ,
The graph of given function is upward (or opens up) because the value of 3 is more than 0, 3 > 0.

The correct option is A. Graph A. It shows an upward-opening parabola with a vertex and y-intercept that match the derived values.
1. Direction of the Parabola : Since the coefficient of [tex]\( x^2 \)[/tex] (which is [tex]3[/tex]) is positive, the parabola opens upwards.
2. Vertex : The vertex of a parabola in the form [tex]\( y = ax^2 + bx + c \)[/tex] can be found using the formula for the x-coordinate of the vertex, [tex]\( x = -\frac{b}{2a} \)[/tex]
For the given function:
[tex]\[ a = 3, \quad b = 7 \][/tex]
So,
[tex]\[ x = -\frac{7}{2 \times 3} = -\frac{7}{6} \][/tex]
Next, we find the y-coordinate of the vertex by plugging [tex]\( x = -\frac{7}{6} \)[/tex] back into the equation:
[tex]\[ y = 3\left(-\frac{7}{6}\right)^2 + 7\left(-\frac{7}{6}\right) + 2 \][/tex]
Let's compute that:
[tex]\[ y = 3 \times \frac{49}{36} - \frac{49}{6} + 2 \][/tex]
[tex]\[ y = \frac{147}{36} - \frac{294}{36} + \frac{72}{36} \][/tex]
[tex]\[ y = \frac{147 - 294 + 72}{36} \][/tex]
[tex]\[ y = \frac{-75}{36} \][/tex]
[tex]\[ y = -\frac{25}{12} = -2.083 \][/tex]
Thus, the vertex is approximately at [tex]\(\left( -\frac{7}{6}, -\frac{25}{12} \right)\)[/tex]
3. Y-Intercept : This is the value of [tex]\( y \)[/tex] when [tex]\( x = 0 \)[/tex]
[tex]\[ y = 3(0)^2 + 7(0) + 2 = 2 \][/tex]
The graph should cross the y-axis at [tex]\( y = 2 \)[/tex]
Now, let's compare these features with the provided graphs:
The parabola should open upwards.
The y-intercept should be [tex]2[/tex].
The vertex should be approximately at [tex]\( \left( -\frac{7}{6}, -\frac{25}{12} \right) \)[/tex]

Annita is sewing a lace edge around a rectangular quilt. She will need 150 inches of lace to do the entire quilt. If the quiltis 42
inches wide, how long is the quilt?
A. 75 inches
B. 66 inches
C. 31 inches
D. 33 inches
Answers
With a total perimeter of 150 inches and a width of 42 inches, the length was calculated to be 33 inches, option D.
To determine how long the quilt is, we need to calculate the perimeter of the rectangular quilt and then solve for the missing length. Since Annita needs 150 inches of lace, we know this is the total perimeter (P) of the quilt. The quilt is 42 inches wide. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). We can set up the equation as 150 = 2(length) + 2(42).
Now let's solve for the length (L):
150 = 2L + 84 (since 2(42) is 84)150 - 84 = 2L66 = 2LL = 33 inchesThe length of the quilt is 33 inches, which corresponds to option D.
The length of the quilt is 33 inches.
The correct option is (D).
To find the length of the quilt, we need to use the formula for the perimeter of a rectangle, which is given by:
[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]
Given that the width of the quilt is 42 inches and Annita needs 150 inches of lace to go around the entire quilt, we can set up the equation as:
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
Now, let's solve for the length [tex](\( \text{Length} \)):[/tex]
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
[tex]\[ 75 = \text{Length} + 42 \][/tex]
Subtract 42 from both sides:
[tex]\[ 75 - 42 = \text{Length} \][/tex]
[tex]\[ \text{Length} = 33 \][/tex]
So, the length of the quilt is 33 inches. Therefore, the answer is option D. 33 inches.

C) 26 blocks
Step-by-step explanation:
For the firs one draw a dot where they start. Then draw a line going down and label it 10. Next draw a line going left and label it 24. Connect the end of those who lines to form a triangle. Now we can use the pythagorean theory.
a^2 + b^2 = c^2
a^2= side one (you choose)
b^2= side two (whichever side you didn't use out of the two)
c^2= the hypotenuse( this is the diagonal line you drew connecting the two lines at the end)
10^2 + 24^2 =c^2
100 + 576 =c^2
676=c^2 Since the C is still squared we have to squareroot both sides. This will cancel oout the ^2 on the C.

A pool table is 8 feet long and 4 feet wide. How far is it from one corner pocket to the diagonally opposite corner pocket?
Answers
Using the Pythagorean theorem, the diagonal distance from one corner pocket to the diagonally opposite corner pocket on an 8 foot by 4 foot pool table is about 8.94 feet.
To determine the distance from one corner pocket to the diagonally opposite corner pocket on a pool table, we can use the Pythagorean theorem because the pool table forms a rectangle and the diagonal forms a right triangle with the length and width of the table. Given the dimensions of the pool table as 8 feet long and 4 feet wide, we can label these as the two sides of the right triangle.
The Pythagorean theorem states that for a right triangle with sides of lengths a, b, and hypotenuse c, the relationship between these sides is [tex]a^2 + b^2 = c^2[/tex]. Substituting the given values, we have:
Let's denote the length (8 feet) as a and the width (4 feet) as b.Using the theorem, we calculate the hypotenuse c as [tex]\sqrt{(8^2 + 4^2)}.[/tex]Compute the square of each side: [tex]8^2[/tex] = 64 and [tex]4^2[/tex] = 16.Add these together: 64 + 16 = 80.The hypotenuse (diagonal) c is the square root of 80, which simplifies to 4 [tex]\sqrt(5)[/tex] feet or approximately 8.94 feet.Therefore, the diagonal distance from one corner pocket to the diagonally opposite corner pocket is about 8.94 feet.
