The side length of an equilateral triangle is 7 centimeters. Find the length of the altitude
Answer:
Step-by-step explanation:
The altitude of an equilateral triangle is basically the height of the triangle. We can find this using trigonometry, even though I'm sure there's a beautiful little formula that can find this.
If you cut an equilateral triangle in half, you get two special 30-60-90 triangles. The base of each triangle is 3.5 cm in length, and the height (not the hypotenuse!) is equal to:
\(base*\sqrt{3}\)
So basically we have 3.5(sqrt(3)), or our altitude! Wow, how easy!
\(3.5(\sqrt{3})=6.06\)
Hope this helps!
Trying to get the right number possible. What annual payment is required to pay off a five-year, $25,000 loan if the interest rate being charged is 3.50 percent EAR? (Do not round intermediate calculations. Round the final answer to 2 decimal places.Enter the answer in dollars. Omit $sign in your response.) What is the annualrequirement?
To calculate the annual payment required to pay off a five-year, $25,000 loan at an interest rate of 3.50 percent EAR, we can use the formula for calculating the equal annual payment for an amortizing loan.
The formula is: A = (P * r) / (1 - (1 + r)^(-n))
Where: A is the annual payment,
P is the loan principal ($25,000 in this case),
r is the annual interest rate in decimal form (0.035),
n is the number of years (5 in this case).
Substituting the given values into the formula, we have:
A = (25,000 * 0.035) / (1 - (1 + 0.035)^(-5))
Simplifying the equation, we can calculate the annual payment:
A = 6,208.61
Therefore, the annual payment required to pay off the five-year, $25,000 loan at an interest rate of 3.50 percent EAR is $6,208.61.

Use logarithmic differentiation to find the derivative of the function y=x^2x
The derivative of the function y = x^2x using logarithmic differentiation is dy/dx = x^2x(2 + 2ln(x)).
To find the derivative of the function y = x^2x using logarithmic differentiation, we follow these steps:
Take the natural logarithm of both sides of the equation:ln(y) = ln(x^2x)Apply the logarithmic property to simplify the equation:ln(y) = (2x)ln(x)Differentiate both sides of the equation implicitly:(1/y) * dy/dx = (2x)(1/x) + ln(x)(d/dx)(2x)Simplify the equation:(1/y) * dy/dx = 2 + 2ln(x)Multiply both sides of the equation by y:dy/dx = y(2 + 2ln(x))Substitute the original function back into the equation:dy/dx = x^2x(2 + 2ln(x))Learn more:About logarithmic differentiation here:

To find the derivative of the function y = x^(2x) using logarithmic differentiation, we take the natural logarithm of both sides, apply logarithmic properties, and then differentiate implicitly.
Start by taking the natural logarithm of both sides of the equation:
ln(y) = ln(x^(2x))
Apply the power rule of logarithms to simplify the expression:
ln(y) = 2x * ln(x)
Now, differentiate both sides of the equation implicitly with respect to x:
(1/y) * dy/dx = 2 * ln(x) + 2x * (1/x)
Simplify the expression:
(1/y) * dy/dx = 2 * ln(x) + 2
Multiply both sides by y to isolate dy/dx:
dy/dx = y * (2 * ln(x) + 2)
Substitute the original value of y = x^(2x) back into the equation:
dy/dx = x^(2x) * (2 * ln(x) + 2)
The derivative of the function y = x^(2x) using logarithmic differentiation is dy/dx = x^(2x) * (2 * ln(x) + 2). Logarithmic differentiation is a useful technique for differentiating functions that involve exponentials or complicated algebraic expressions, as it allows us to simplify the calculation by taking the logarithm of both sides and then differentiating implicitly.

How is copying segment similar to copying an angle ?
Answer:
Copying a line segment or angle is an illustration of transformation. Both are similar, because they are both rigid transformation.
When an angle is copied to a new angle, the new angle and the old angle will have the same measure
Similarly;
When a line segment is copied to a new segment, the new line segment and the old line segment will have the same measure
This type of transformation is referred to as a rigid transformation.
Hence, copying a line segment is similar to copying an angle, because they are both rigid transformations

how to determine magnitude of order
For some values, such as the speed of light or the separation between the Earth and the sun, scientists and mathematicians long ago realized they needed a simpler way to write and refer to these large numbers.
They developed/created scientific notation at that time.
For us to estimate the order of magnitude:
Firstly, write the number in scientific notation.
Secondly, Round up to the nearest integer times a power of ten or power of ten.
Thirdly, Apply these estimates to your calculations.
Fourthly, If possible, compare the result to the exact one.
Example question, How many orders of magnitude are there in one million, for instance?
Answer will be, In order to represent the number 1,000,000, we will move the decimal to the left, stopping just before the first digit. The order of magnitude is determined by the quantity of left moves you make. Since we moved it six times, there are six orders of magnitude between ten and one million, which means that ten times six is equal to one million.

g every time the syste, transitions it is equally likely to choose any of the three modes. what is the expected time taken for the system to fail
The expected time taken for the system to fail is dependent on the specific details of the system in question.
However, if we assume that the three modes have equal probabilities of occurring and that the failure occurs when the system reaches a specific mode, we can use the concept of Markov chains to find the expected time until failure.
In this case, the expected time until failure would be the reciprocal of the probability of the system transitioning to the failure mode.
Therefore, if each mode has an equal probability of 1/3, the expected time until failure would be 3 units of time.

Mrs. Rosenblatt's class has an average grade of 87. After realizing she left out Joe's score of 65, the new mean will be lower than 87.
Explanation:
To find the new mean, we need to calculate the sum of all the grades in the class, including Joe's score of 65, and divide it by the total number of students in the class. Let's assume there are n students in the class.
The sum of all the grades in the class, including Joe's score, will be (87 * n) + 65, since the average grade before Joe's score was added was 87. Therefore, the new mean will be:
[(87 * n) + 65] / (n + 1)
Expanding this expression, we get:
(87n + 65) / (n + 1)
Simplifying this expression, we get:
(87n / (n + 1)) + (65 / (n + 1))
Since n is a positive integer, the value of (87n / (n + 1)) will be slightly less than 87. Therefore, the new mean will be slightly less than 87, reflecting the lower score added to the class average.

The actual value of the sample average may vary due to chance, and the typical distance it is away from the expected value is about 0.24 feet.
Given that a large population of Indian elephants has an average height of 9 feet with an SD of 0.75 feet, we can use this information to answer the following questions.
If 10 elephants are selected at random, the expected average height of these 10 elephants is still 9 feet. This is because the population average height of 9 feet remains unchanged, even if we randomly select a smaller group of elephants.
However, the actual value of the sample average may vary due to chance. This variation in the sample average is measured by the standard error of the mean (SEM). The SEM is calculated as the standard deviation of the sample divided by the square root of the sample size. For a sample size of 10, the SEM would be 0.24 feet.
Therefore, the typical distance the sample average is away from its expected value is about 0.24 feet. This means that if we were to repeat this random sampling process many times, the average height of the 10 elephants would vary by approximately 0.24 feet on average.
In summary, if 10 elephants are randomly selected from a large population of Indian elephants with an average height of 9 feet and an SD of 0.75 feet, we can expect the average height of these 10 elephants to be 9 feet.

what is the maximum length of instruction for 8086 based-ibm pc?
The maximum length of an instruction for the 8086-based IBM PC is 15 bytes.
The 8086 microprocessor was used in the original IBM PC and was capable of executing instructions up to 15 bytes in length. The instruction length is determined by the number of bytes needed to encode the operation code, the addressing mode, and any operands.
The maximum length of 15 bytes allows for complex instructions that can perform multiple operations in a single instruction cycle, increasing the efficiency of the processor. However, not all instructions require the full 15 bytes, and many are much shorter, so the average instruction length is typically much less than 15 bytes.

In 1999, 2.2% of all cars in the United States were reported stolen. In a random sample of 400 Nissan Maxima cars that year, 12 were reported stolen. Is this evidence (at the  = 0.05 level) that the theft rate for this model is higher than the national rate?
Answer:
The evidence is not sufficient to suggest that the theft rate of Nissan Maxima cars are higher than national rate
Step-by-step explanation:
The number of cars that where reported stolen in 1999 = 2.2% = 0.022
The number of Nissan Maxima cars in the sample = 400
The number of Nissan Maxima cars that were reported stolen = 12
The level of significance, α = 0.05 level
The critical-z at 0.05 = 5% level = 1.645
The percentage of Nissan Maxima cars reported stolen, \(\hat p\) = 12/400×100 = 3%
The test statistic is given as follows;
\(z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0 \cdot (1 - p_0)}{n}}}\)
Therefore
\(z=\dfrac{0.03-0.022}{\sqrt{\dfrac{#0.022 \cdot (1 - #0.022)}{400}}} \approx 1.0908\)
The test statistic = 1.0908
The p-value P(Z > 1.0908) = 1 - P(Z > 1.0908) = 1 - 0.86214 = 0.13768
Given that the critical-z is larger than the absolute value of the test statistic, the given data is statistically insignificant, we fail to reject the null hypothesis
There is not enough statistical evidence to suggest that the theft rate of Nissan Maxima cars are higher than national rate.

a² + 14a = 51
to complete the square
add ( half the coefficient of the x- term )² to both sides
a² + 2(7)a + 49 = 51 + 49
(a + 7)² = 100 ( take square root of both sides )
a + 7 = ± \(\sqrt{100}\) = ± 10 ( subtract 7 from both sides )

Question 3 ABC needs money to buy a new car. His friend accepts to lend him the money so long as he agrees to pay him back within five years and he charges 7% as interest (compounded interest rate). a) ABC thinks that he will be able to pay him $5000 at the end of the first year, and then $8000 each year for the next four years. How much can ABC borrow from his friend at initial time. b) ABC thinks that he will be able to pay him $5000 at the end of the first year. Estimating that his salary will increase through and will be able to pay back more money (paid money growing at a rate of 0.75). How much can ABC borrow from his friend at initial time.
ABC needs money to buy a new car.
a) ABC can borrow approximately $20500.99 from his friend initially
b) Assuming a payment growth rate of 0.75, ABC can borrow approximately $50139.09
a) To calculate how much ABC can borrow from his friend initially, we can use the present value formula for an annuity:
PV = PMT * [(1 - (1 + r)^(-n)) / r]
Where PV is the present value, PMT is the annual payment, r is the interest rate, and n is the number of years.
In this case, ABC will make annual payments of $5000 in the first year and $8000 for the next four years, with a 7% compounded interest rate.
Calculating the present value:
PV = 5000 * [(1 - (1 + 0.07)^(-5)) / 0.07]
PV ≈ $20500.99
Therefore, ABC can borrow approximately $20500.99 from his friend initially.
b) If ABC's salary is estimated to increase at a rate of 0.75, we need to adjust the annual payments accordingly. The new payment schedule will be $5000 in the first year, $5000 * 1.75 in the second year, $5000 * (1.75)^2 in the third year, and so on.
Using the adjusted payment schedule, we can calculate the present value:
PV = 5000 * [(1 - (1 + 0.07)^(-5)) / 0.07] + (5000 * 1.75) * [(1 - (1 + 0.07)^(-4)) / 0.07]
PV ≈ $50139.09
Therefore, ABC can borrow approximately $50139.09 from his friend initially, considering the estimated salary increase.

Let's denote the number of slices with both pepperoni and mushrooms as $x$. We are given that there are 6 slices with pepperoni and 10 slices with mushrooms.
Since every slice has at least one topping, the total number of slices is 12. We can break down the slices into the following categories:
Slices with only pepperoni: 6 slices
Slices with only mushrooms: 10 slices
Slices with both pepperoni and mushrooms: $x$ slices
Slices with neither pepperoni nor mushrooms: 12 - (6 + 10 + x) slices
We know that the total number of slices is 12, so we can write an equation:
6 + 10 + x + (12 - (6 + 10 + x)) = 12
