what is the area of the smaller figure, in square centimeters?
a. 4
b. 8
c. 20
d. 40
A composite figure consists of two smaller figures - a rectangle and a Triangle. Therefore, the answer is 4 cm² (option a).
A composite figure that consists of two smaller figures - a rectangle and a triangle.
To find the area of the composite figure, we need to find the area of each smaller figure and add them up .Areaof rectangle to find the area of the rectangle, we need to multiply its length and width :Area of rectangle = 2 cm × 4 cm = 8 cm²Areaof triangle too find the area of the triangle, we need to use the formula :
Area of triangle = 1/2 × base ×heightT
he base of the triangle is 4 cm and the height is 2 cm, so:
Area of triangle = 1/2 × 4 cm × 2 cm = 4 cm²Area of composite figure To find the area of the composite figure, we need to add up the area of the rectangle and the area of the triangle: Area of composite figure = 8 cm² + 4 cm² = 12 cm². Therefore, the answer is 4 cm² (option a).

You have been offered a unique investment opportunity. If you invest $10,000 today, you will receive $500 one year from now, $1,500 two years from now, and $10,000 ten years from now a. What is the NPV of the investment opportunity if the interest rate is 6% por year? Should you take the opportunity? b. What is the NPV of the investment opportunity if the interest rate is 2% per year? Should you take the opportunity? a. What is the NPV of the investment opportunity if the interest rate is 6% per year? The NPV of the investment opportunity at the interest rate is 0% per year is $(Round to the nearest dollar)
The NPV of the investment opportunity at a 6% interest rate is approximately $6,374. Taking into account the timing and value of the cash flows, it is advisable to take the opportunity.
The Net Present Value (NPV) of an investment opportunity calculates the present value of future cash flows discounted at a specific interest rate. Let's calculate the NPV at a 6% interest rate:
Year 1: Receive $500.
Year 2: Receive $1,500.
Year 10: Receive $10,000.
To find the NPV, we need to discount each cash flow back to its present value and sum them up:
NPV = (Cash flow at Year 1 / (1 + Interest rate)^1) + (Cash flow at Year 2 / (1 + Interest rate)^2) + (Cash flow at Year 10 / (1 + Interest rate)^10) - Initial investment
Plugging in the values, we get:
NPV = (500 / (1 + 0.06)^1) + (1500 / (1 + 0.06)^2) + (10000 / (1 + 0.06)^10) - 10000
≈ $6,374
Therefore, at a 6% interest rate, the NPV of the investment opportunity is approximately $6,374. Since the NPV is positive, it indicates that the investment is expected to generate a return greater than the cost of capital. Hence, it is advisable to take the opportunity.
(Note: The calculation for the NPV at 0% interest rate requires all future cash flows to be treated at their face value. Therefore, the NPV at a 0% interest rate would be equal to the sum of all future cash flows, which is $11,000 in this case.)

Find the Laplace transform F(s) = L {f(t)} of the function f(t) = et-³h(t – 3), defined on the interval t > 0. F(s) = L {et ³h(t - 3)}
The Laplace transform of f(t) = et-³h(t – 3) is F(s) = 1/3 * 1/(s + 3) - 1/3 * 1/s, or F(s) = (s - 1)/(3s(s + 3)).
To find the Laplace transform F(s) = L{f(t)} of the function f(t) = et-³h(t – 3), we can use the properties and formulas of Laplace transforms. Let's break down the function and compute its transform step by step.
et-³: This term represents the exponential function with a power of t-³. The Laplace transform of et is given by 1/(s - a), where a is the exponent in the exponential function. Therefore, the Laplace transform of et-³ is 1/(s + 3).
h(t - 3): This term represents the Heaviside step function, h(t), shifted by 3 units to the right. The Laplace transform of the Heaviside step function h(t) is 1/s. When the function is shifted by a constant, the Laplace transform remains the same.
Combining these results, we have F(s) = L{f(t)} = 1/(s + 3) * 1/s.
To simplify the expression, we can use partial fraction decomposition:
1/(s + 3) * 1/s = A/(s + 3) + B/s.
Solving for A and B by equating numerators, we find A = 1/3 and B = -1/3.
Therefore, the Laplace transform of f(t) = et-³h(t – 3) is F(s) = 1/3 * 1/(s + 3) - 1/3 * 1/s, or F(s) = (s - 1)/(3s(s + 3)).

Answer:
Parallelogram Theorem #1 Converse
Step-by-step explanation: : If each of the diagonals of a quadrilateral divide the quadrilateral into two congruent triangles, then the quadrilateral is a parallelogram. Parallelogram Theorem #2 Converse: If the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
Parallelogram opposite sides converse. Therefore, option A is the correct answer.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
Let the diagonals AC and BC intersect at O.
Consider, triangle BOC and triangle AOD
OA=OC (Shown in the figure)
∠AOD=∠BOC (Vertically opposite angles are equal)

Given:
Discount rate = 30% = 0.30
Amount save by Lisa = $9
Number of charger = 4
Find:
Cost of each cord
Computation:
Total cost of 4 charger = Amount save by Lisa[1/Discount rate]
Total cost of 4 charger = 9[1/0.30]
Total cost of 4 charger = $30
Cost of each cord = Total cost of 4 charger / Number of charger
Cost of each cord = $30 / 4
Cost of each cord = $7.5
