A spider walks on the outside of a box from point A to B to C to D
and finally to point E as shown in the picture below. How long is
the path of the spider?
Answers
The path consists of 4 line segments. Each line segment is the hypotenuse of a different right triangle.
length of line segment AB = \(\sqrt{2^{2}+5^{2} } =\sqrt{29} =5.39cm\)
length of line segment BC = \(\sqrt{3^{2}+4^{2} } =\sqrt{25} =5cm\)
length of line segment CD = \(\sqrt{3^{2}+5^{2} } =\sqrt{34} =5.83cm\)
length of line segment DE \(=\sqrt{2.5^{2}+3^{2} } } =\sqrt{15.25} =3.91cm\)
The total length of the spider's path is about 20.13 cm.

wich equation represents a line which is parallel to the line y=-4/7x-4
Answers
Answer:
D
Step-by-step explanation:
A parallel function is a function that has the same slope as the original with a different y-intercept.
a. Lest convert it into slope intercept form to see if the slope is the same
1. 7x+4y=32
2. 4y=-7x+32
3. y=-7/4x+8
its not, so onto option b!
b. We see that the positive becomes a negative but the numbers stay the same, so the slope would be 4/7x, which isnt what we need
c. The slope would be a form of 7/4 which isn't what we want
d. We know this is correct due to process of elimination, but let's work it through
1. 7y = -4x-14
2.y=-4/7x-2
Slopes match!
Y intercepts are different!
Thus the answer is D
What is the three-period weighted moving average for july using the weights 0.5 (most recent), 0.3, and 0.2?
Answers
The three-period weighted moving average for july is 145.4.
What is Weighted Moving Average?A weighted moving average technique is one of several methods for forecasting a given month's value or attribute. Other techniques for forecasting from historical data include the evenly weighted moving average method, a regression analysis method, and so on.
When evaluating the movable average estimate of such an observation, each observation is usually weighted the same way. In some cases, it is advantageous to assign different weights to the observations so that the observation closest to the forecasted time period has a higher weight. This is known as the weighted moving average method. In such a weighted moving average technique, the sum of the individual weights must equal 1.Now, according to the question;
The weighted moving average strategy forecast for month of July is given by:
= (Weight for May * Sales for May) + (Weight for April * Sales for April) + (Weight for June * Sales for June)
= (0.5 * 148) + (0.3 * 142) + (0.2* 144)
= 145.4
Therefore, the three-period weighted moving average for july is 145.4.

Suppose you borrowed $11,000 at a rate of 11.2% and must repay it in 5 equal installments at the end of each of the next 5 years. How much interest would you have to pay in the first year? Show your calculation
Answers
1. Using the formula of present value, the amount of the payment is $5000.
2. The interest to be paid in the first year is $1232
How large would the payments be?1. To calculate the size of the payments for the loan of $16,000 at a rate of 9.0% to be repaid in 4 equal installments, we can use the formula for the equal periodic payment amount on an installment loan. The formula is given by:
Payment = Loan Amount / Present Value Factor
Where the Present Value Factor can be calculated using the formula:
Present Value Factor = (1 - (1 + interest rate)^(-number of periods)) / interest rate
Let's calculate the size of the payments:
Interest Rate = 9.0% = 0.09
Number of Periods = 4
Present Value Factor = (1 - (1 + 0.09)⁻⁴) / 0.09
Present Value Factor = 3.2
Payment = $16,000 / 3.2 = $5000
The payment is $5000
Therefore, the size of the payments would be approximately $4,935.77.
2. Let's find the interest of the first payment;
The interest component of the first payment can be calculated as:
Interest = Loan Amount * Interest Rate
Let's calculate the interest payment:
Loan Amount = $11,000
Interest Rate = 11.2% = 0.112
Interest = $11,000 * 0.112
Interest = $1,232
Therefore, the interest to be paid in the first year would be $1,232.

The table shows three functions and their output values for different values of x. Which equation represents h(x)? h(x) = (f(x))(g(x)) h(x) = f(x) – g(x) h(x) = f(x) + g(x)
Answers
The equation that represents h(x) is h(x) = (f(x))(g(x)).
To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).
Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).
Let's examine the table and compare the values:
x | f(x) | g(x) | h(x)
1 | 3 | 4 | 12
2 | 5 | 2 | 10
3 | 2 | 6 | 12
From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).

A board 65 inches long is sawed into two pieces. One of the pieces in 7 inches shorter than twice the length of the other piece. Find the length of the two pieces.
Answers
Answer:
24 and 41 inches.
Step-by-step explanation:
Let the lengths of the two pieces be a and b.
The total length of the two-piece should be the length of the original board.
Therefore:
a + b = 65
One piece, say b, is 7 inches shorter than twice the length of the other, a.
Therefore, we can write the following equation:
b = 2a - 7
The “2a” represents the twice, and the “-7” represents the 7 shorter inches.
We now have a system of equations:
a + b = 65
b = 2a - 7
We can solve using substitution. Substitute the second equation with the first. Hence:
a + (2a - 7) = 65
Combine like terms:
3a - 7 = 65
Add 7 to both sides:
3a = 72
Divide both sides by 3:
a = 24
So, the shorter piece is 24 inches.
Then, we can use our second equation again:
b = 2a - 7
Since we now know a substitute 24 for a and evaluate. Hence:
b = 2(24) - 7
= 48 - 7
= 41
Therefore, the length of the other two pieces is 24 and 41 inches.

Answers
The angle relationships that is supplementary is angle 1 and angle 5.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
In other words, supplementary angles refer to the pair of angles that always sum up to 180°.
Alternate exterior angles are congruent to each other.
Therefore, ∠1 and ∠4 are not supplementary angles.
Hence,
m∠4 =m∠1
m∠4 = 85°
Consecutive interior angles are supplementary. That is they sum up to 180 degrees.
m∠1 = 43°
m∠5 = 180 - 43
m∠5 = 137°

regression analysis was applied and the least squares regression line was found to be ŷ = 800 3x. what would the residual be for an observed value of (5, 811)?
a. -4
b. 4
c. 811
d. 815
Answers
The residual for the observed value (5, 811) is -4. The correct answer is (a) -4.
To find the residual for an observed value, we need to compare the observed value with the predicted value based on the least squares regression line.
The least squares regression line is given by the equation ŷ = 800 + 3x, where ŷ represents the predicted value of the dependent variable y, and x represents the independent variable.
For the observed value (5, 811), the x-value is 5, and the y-value is 811. We can substitute the x-value into the equation of the regression line to find the predicted value:
ŷ = 800 + 3(5)
= 800 + 15
= 815
The predicted value for the observed value (5, 811) is 815.
The residual is calculated by subtracting the predicted value from the observed value:
Residual = Observed value - Predicted value
= 811 - 815
= -4

Let's explore the intersection of statistics and mechatronics. Here we estimate the probability of rolling doubles with two dice ("doubles" is defined here as the event where both dice result in the same value on a particular roll). Using your Arduino, write a script that runs through a loop 10,000 times in which random numbers are generated representing each dice and a count is kept of how many times doubles appear. After completing the 10,000 dice rolls, print out the final percentage of rolls that are doubles to the Serial Monitor. Your script should run this process only one time when power is applied to the Arduino, i.e. your script should only provide a single percentage value when power is applied.
Answers
The program calculates the percentage of doubles and displays the result in the Serial Monitor when power is applied to the Arduino.
To write a script that runs through a loop 10,000 times to estimate the probability of rolling doubles with two dice using Arduino, one can follow the below steps:
Define variables and initialize the random seed.
The variables required are `dice1`, `dice2`, `count`, `total`, and `percentage`.The `randomSeed()` function is used to initialize the random number generator.
In the `setup()` function, the function `Serial.begin()` is used to initiate the Serial Monitor with a baud rate of 9600.```
int dice1, dice2, count = 0, total = 0;
float percentage = 0.0;
void setup() {
Serial.begin(9600);
randomSeed(analogRead(0));
}
The `for` loop runs for 10,000 times and generates random numbers between 1 and 6, representing each dice.```
for (int i = 1; i <= 10000; i++) {
dice1 = random(1, 7);
dice2 = random(1, 7);
If both dice have the same number, increment the count by 1.```
if (dice1 == dice2) {
count++;
Add 1 to the total irrespective of whether it's a double or not.```total++;
}
After the loop, calculate the percentage of doubles and print the result to the Serial Monitor.
percentage = (count / float(total)) * 100;
Serial.print("Percentage of doubles: ");
Serial.print(percentage);
Serial.println("%");
The final program would look like this:```int dice1, dice2, count = 0, total = 0;
float percentage = 0.0;
void setup() {
Serial.begin(9600);
randomSeed(analogRead(0));
}
void loop() {
for (int i = 1; i <= 10000; i++) {
dice1 = random(1, 7);
dice2 = random(1, 7);
if (dice1 == dice2) {
count++;
}
total++;
}
percentage = (count / float(total)) * 100;
Serial.print("Percentage of doubles: ");
Serial.print(percentage);
Serial.println("%");
while (true) {}
}
The `while (true)` loop at the end is used to keep the program running and displaying the result in the Serial Monitor.

(ii) The set E, which is a subset of A∪B∪C with the fewest elements, is the empty set, represented by { }.
(i)The set D that is a subset of A∩B∩C with the most elements is { }.
First, let's find the intersection of sets A, B, and C:
A∩B = { }
A∩C = {a, b, c, d}
B∩C = {e, f}
A∩B∩C = { } (empty set)
Since the empty set has no elements, it is the subset of A∩B∩C with the most elements, which is none.
(ii) The set E that is a subset of A∪B∪C with the fewest elements is { }.
To find the subset of A∪B∪C with the fewest elements, we need to consider the smallest possible combination of elements.
A∪B∪C includes all the elements from sets A, B, and C:
A∪B∪C = {a, b, c, d, e, f}
The subset with the fewest elements is the empty set, represented by { }, as it contains no elements.

The value of a Van Gogh painting increases by 7.3% each year. If it was valued at $94,000 in 1952, what will be its estimated worth in 2020?
Answers
Answer:
$11,321,630
Step-by-step explanation:
We solve using Exponential growth formula
A(t) = Ao (1 + r)^t
Ao = Initial worth = $94,000
r = Growth rate = 7.3% = 0.073
t = Time in years = 2020 - 1952
= 68 years
A(t) = Current worth in 2020 = After 68 years
A(t) = 94000 × ( 1 + 0.073)^68
A(t) = 94000 × 120.44286946
A(t) = 11,321,629.729
Therefore, the estimated worth of the Van Gogh painting in 2020 approximately = $11,321,630
