The distance from the bottom of the building to the point where the ladder is touching the building for Triangle 2 is 14 feet.

What is triangle?

A triangle is a polygon with three sides and three angles. It is one of the most basic geometric shapes and is often used in geometry, trigonometry, and other branches of mathematics.

Since Triangle 1 and Triangle 2 are similar right triangles formed from the same ladder leaning against the same building, their corresponding sides are proportional to each other.

Let's use the concept of similarity and proportions to solve for the unknown distance in Triangle 2. We can set up the following proportion based on the corresponding sides of the two triangles:

(vertical leg of Triangle 1) : (horizontal leg of Triangle 1) = (vertical leg of Triangle 2) : (horizontal leg of Triangle 2)

We know that in Triangle 1:

the length of the hypotenuse (the ladder) is 16 feet

the length of the horizontal leg (the distance along the ground) is 8 feet

the length of the vertical leg (the distance from the bottom of the building to the point where the ladder is touching the building) is 16 feet

Using the Pythagorean Theorem, we can solve for the length of the vertical leg of Triangle 2:

(vertical leg of Triangle 1) : (horizontal leg of Triangle 1) = (vertical leg of Triangle 2) : (horizontal leg of Triangle 2)

16 : 8 = (vertical leg of Triangle 2) : 7

Simplifying the proportion, we get:

2 : 1 = (vertical leg of Triangle 2) : 7

To solve for the vertical leg of Triangle 2, we can multiply both sides of the proportion by 7:

2 * 7 : 1 * 7 = (vertical leg of Triangle 2)

14 : 1 = (vertical leg of Triangle 2)

Therefore, the distance from the bottom of the building to the point where the ladder is touching the building for Triangle 2 is 14 feet.

A sample size of 1068 is needed with a 95% confidence level and a 3% margin of error to estimate the proportion of people who support a political candidate.

To determine the sample size needed to estimate the percentage of people who support the political candidate with a 3% margin of error at a 95% confidence level, we can use the formula:

n = (z^2 * p * (1 - p)) / (E^2)

where n is the sample size, z is the z-value corresponding to the desired confidence level (95% confidence level corresponds to z = 1.96), p is the estimated proportion of the population that supports the candidate (we can use 0.5 as a conservative estimate), E is the desired margin of error (3% or 0.03)

Substituting the values into the formula, we get:

n = (1.96^2 * 0.5 * (1 - 0.5)) / (0.03^2) = 1067.11

The formula to calculate interest charge when the musician does not make any payments for one month is Interest = Principal * Rate * Time. Using the given values, the interest charge for the first month is $97.15, making the total owed amount at the end of the first month $2,997.15.

If the musician does not make any payments for one month, the amount owed will accumulate interest. To calculate the interest charge, we can use the following formula:

Interest = Principal * Rate * Time

where the principal is the initial amount owed, the rate is the monthly interest rate as a decimal, and the time is the time period in months.

In this case, the principal is $2,900, the monthly interest rate is 3.35% expressed as a decimal (0.0335), and the time is one month.

So, the interest charge for the first month will be:

Interest = $2,900 * 0.0335 * 1

Interest = $97.15

Therefore, at the end of the first month, the musician will owe the initial balance of $2,900 plus the interest charge of $97.15, for a total of $2,997.15.

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its energy of combustion is known very accurately (-26.43 kJ/g).

The calorimeter constant is -2873.5.

Determine the calorimeter constant of the calorimeter that had a temperature increase of 9.199 degrees Celsius when 3.500 g of benzoic acid was used.To determine the calorimeter constant, follow these steps:

Explanation:

1. Calculate the energy released by the benzoic acid combustion: Multiply the mass of benzoic acid by its energy of combustion.
Energy released = mass × energy of combustion
Energy released = 3.500 g × -26.43 kJ/g = -92.505 kJ

2. Convert the temperature increase to a change in energy: Multiply the temperature increase by the mass of benzoic acid.
ΔEnergy = temperature increase × mass of benzoic acid
ΔEnergy = 9.199°C × 3.500 g = 32.1965 J

3. Determine the calorimeter constant: Divide the energy released by the change in energy.
Calorimeter constant = Energy released / ΔEnergy
Calorimeter constant = -92.505 kJ / 32.1965 J

Note: We need to convert the units to be consistent, either to J or kJ.
1 kJ = 1000 J, so -92.505 kJ = -92505 J.

Calorimeter constant = -92505 J / 32.1965 J = -2873.5

The calorimeter constant is -2873.5.

so, we can go ahead and pull that number in.

now we have to subtract the 3 to try and get as much as possible over on the other side to find t.

10=30t-5t^2

Step-by-step explanation:

h(t) = 3 + 30t - 5t²

the height is set to 13 meters.

since the ball will go up and then come back down again, we expect 2 points of time, when the ball is at 13 meters high. if any at all, by the way (keep that in mind for similar questions, the object might not even reach a certain height).

13 = 3 + 30t - 5t²

10 = 30t - 5t²

ax² + bx + c = 0

is

x = (-b ±sqrt(b² - 4ac))/(2a)

a = -1

b = 6

c = -2

t = (-6 ±sqrt(6² - 4×-1×-2))/(2×-1) =
