If $3000 grows to $3480 in 4 years, find the simple interest rate
Formula of simple interest rate is:
\(A=P(1+rt)\)Where,
\(\begin{gathered} A=\text{ final amount} \\ P=\text{ initial principal anount} \\ r=\text{rate} \\ t=\text{time} \end{gathered}\)So the interest rate is:
\(\begin{gathered} 3480=3000(1+r\times4) \\ \frac{3480}{3000}=1+4r \\ 1.16=1+4r \\ 4r=1.16-1 \\ 4r=0.16 \\ r=0.04 \end{gathered}\)So the simple interest rate is:
\(\begin{gathered} 0.04\times100 \\ =4 \end{gathered}\)4% interest rate.

I don't really know if its right so don't count on this too much.
Step-by-step explanation:
Answer:
9 m³Step-by-step explanation:
given:
crane capacity = 17,000 kg
bucket mass = 3,000 kg
gravel mass = 1,500 kg/m³
find:
how many cubic meters of gravel (g) can be safely lifted by the crane?
crane capacity = 17,000 - 3,000
= 14,000 kg
volume of gravel with respect to crane's capacity:
vol. = 14,000 kg
1,500 kg/m³
= 9.33 m³ (say 9 m³)
therefore, the crane can safely lift the bucket + 9 m³ of gravel

If a point is originally located at (2,9) and is translated 4 units to the right and 7 units up, what would its new
coordinates be?
Given:
The point is (2,9).
It is translated 4 units to the right and 7 units up.
To find:
The coordinates of new point.
Solution:
The point is translated 4 units to the right and 7 units up. So, the rule of translation is
\((x,y)\to (x+4,y+7)\)
The point is (2,9). Using the above rule, we get
\((2,9)\to (2+4,9+7)\)
\((2,9)\to (6,16)\)
Therefore, the coordinates of new points are (6,16).

consider an undirected random graph of eight vertices. the probability that there is an edge between a pair of vertices is 1/2. what is the expected number of unordered cycles of length three?
In this random graph, we expect to find approximately 14 unordered cycles of length three.
In an undirected random graph of eight vertices, where the probability of an edge existing between any pair of vertices is 1/2, we can calculate the expected number of unordered cycles of length three.
To determine the expected number, we need to analyze the probability of forming a cycle of length three through any three vertices.
To form a cycle of length three, we must select three distinct vertices. The probability of selecting a particular vertex is 1, and the probability of not selecting it is (1 - 1/2) = 1/2. Hence, the probability of selecting three distinct vertices is (1)(1/2)(1/2) = 1/4.
Since we have eight vertices, the number of ways to choose three distinct vertices is given by the combination formula C(8, 3) = 8! / (3! * (8 - 3)!) = 56.
Therefore, the expected number of unordered cycles of length three is the product of the probability and the number of ways to choose the vertices: (1/4) * 56 = 14.
Therefore, in this random graph, we expect to find approximately 14 unordered cycles of length three.

we assume that with a linear relationship between two variables, for any fixed value of x, the observed ________ follows a normal distribution.
We assume that with a linear relationship between two variables, for any fixed value of x, the observed residuals follows a normal distribution.
This assumption is based on the Central Limit Theorem, which states that when the sample size is large enough, the distribution of sample means will be approximately normal, regardless of the shape of the underlying population distribution.
In the case of a linear relationship between two variables, we can assume that the residuals (the difference between the observed y values and the predicted values based on the linear regression model) follow a normal distribution with mean 0 and constant variance. This assumption is important because it allows us to use statistical methods that rely on normality, such as hypothesis testing and confidence intervals.

What is the angle relation?
Answer:
the angles in matching corners when two lines are crosed by another line
6sin^2 (x) + 6sin (x) + 1 = 0
solve and show steps for the graph ( i already have the graph )
To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.
1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.
2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.
3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.
4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.
5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].
6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.
7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

gement System Grade 0.00 out of 10.00 (0%) Plainfield Electronics is a New Jersey-based company that manufactures industrial control panels. The equation gives the firm's production function Q=-L³+15
The equation Q = -L³ + 15 represents the production function of Plainfield Electronics, where Q is the quantity of industrial control panels produced and L is the level of labor input.
In this production function, the term -L³ indicates that there is diminishing returns to labor. As the level of labor input increases, the additional output produced decreases at an increasing rate. The term 15 represents the level of output that would be produced with zero labor input, indicating that there is some fixed component of output. To maximize production, the firm would need to determine the optimal level of labor input that maximizes the quantity of industrial control panels produced. This can be done by taking the derivative of the production function with respect to labor (dQ/dL) and setting it equal to zero to find the critical points. dQ/dL = -3L². Setting -3L² = 0, we find that L = 0.
Therefore, the critical point occurs at L = 0, which means that the firm would need to employ no labor to maximize production according to this production function. However, this result seems unlikely and may not be practically feasible. It's important to note that this analysis is based solely on the provided production function equation and assumes that there are no other factors or constraints affecting the production process. In practice, other factors such as capital, technology, and input availability would also play a significant role in determining the optimal level of production.
