We can use the point-slope form of the equation of a line to find the equation of the tangent line.

To find the equation of the line that is tangent to circle A from point C (2, 8), we need to first find the point of tangency, which is the point where the line intersects the circle.

Point C (2, 8) is outside the circle, so the tangent line will be perpendicular to the line connecting the center of the circle to point C and will pass through point C.

Step 1: Find the center of the circle

The center of the circle A is at (6, 5).

Step 2: Find the slope of the line connecting the center of the circle to point C

The slope of the line connecting the center of the circle (6, 5) and point C (2, 8) is:

m = (8 - 5) / (2 - 6) = -3/4

Step 3: Find the equation of the line perpendicular to the line from Step 2 passing through point C

The slope of the line perpendicular to the line from step 2 is the negative reciprocal of the slope:

m_perp = -1 / (-3/4) = 4/3

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - 8 = (4/3)(x - 2)

Simplifying, we get:

y = (4/3)x + 4.67

So the equation of the line that is tangent to circle A from point C (2, 8) is y = (4/3)x + 4.67.

The significant increase in the percent of filers between the under-18 group and the 18-26 group can be attributed to various factors, including age, income, and financial independence.

Firstly, individuals under the age of 18 are typically considered minors and are often dependent on their parents or guardians for financial support. As a result, they may not have any significant income that requires them to file taxes, and their income might be included in their parent's or guardian's tax return. This leads to a lower percentage of filers in the under-18 group.

On the other hand, the 18-26 age group marks the transition into adulthood, where individuals begin to gain financial independence. Many start working full-time jobs or attend college, where they may earn income through part-time jobs or internships. This increased income leads to a higher percentage of filers in the 18-26 group, as they are now responsible for filing their own tax returns.

Furthermore, the age range of 18-26 also coincides with the period where individuals are more likely to have various income sources. This includes scholarships, grants, and student loans for those attending college. These additional income sources may also contribute to the increased percentage of filers in this age group.

Lastly, as individuals become more financially independent, they may become more aware of tax benefits and deductions available to them, such as educational credits or deductions for student loan interest. This newfound awareness could encourage more people within the 18-26 age group to file taxes, leading to a higher percentage of filers.

In conclusion, the dramatic jump in the percent of filers between the under-18 group and the 18-26 group can be attributed to factors such as increased financial independence, diverse income sources, and greater awareness of tax benefits and deductions.

It takes about 1.5 seconds for the ball to hit the ground.

To find how long it takes for the ball to hit the ground, we need to find the value of x when h(x) = 0, since the height of the ball is 0 when it hits the ground. We can set -16x²+36 = 0 and solve for x:

-16x²+ 36 = 0

Dividing both sides by -16:

x² - 2.25 = 0

Adding 2.25 to both sides:

x²= 2.25

Taking the square root of both sides (we can ignore the negative root since time cannot be negative):

x = √(2.25) ≈ 1.5

Therefore, it takes about 1.5 seconds for the ball to hit the ground.

The amount of magnesium sulfate produced from the given reaction cannot be determined solely from the energy absorbed by the reaction.

The given reaction is: Al2(SO4)3 + 3 MgI2 → 2 AlI3 + 3 Mg(SO4) and the enthalpy change for the reaction is ΔH = +722 kJ. The enthalpy change indicates that the reaction is endothermic, meaning that energy is absorbed by the reaction. The question asks about the amount of magnesium sulfate produced, which is not directly related to the energy absorbed by the reaction.

The balanced chemical equation shows that the reaction produces 3 moles of magnesium sulfate for every 3 moles of magnesium iodide consumed. Therefore, the amount of magnesium sulfate produced depends on the amount of magnesium iodide consumed.

To determine the amount of magnesium sulfate produced, we would need information about the amount of magnesium iodide consumed. The energy absorbed by the reaction does not provide enough information to determine the amount of magnesium sulfate produced.

In summary, the amount of magnesium sulfate produced from the given reaction cannot be determined solely from the energy absorbed by the reaction.

The given volume of the cube, v₁ = 1 unit cube

The height of the unit cube, h₁ = 1 unit

The length of the unit cube, w₁ = 1 unit

The height of the unit cube, l₁ = 1 unit

The number of identical prism located along the height = 2 identical prism

The number of identical prism located along the width = 2 identical prism

The number of identical prisms located along the length = 4 identical prism

We know that the indicated probability is approximately 0.1210.

To use the normal approximation, we need to check if the conditions for a normal approximation are met. In this case, we have:

np = 81 * 0.5 = 40.5 ≥ 10
n(1-p) = 81 * 0.5 = 40.5 ≥ 10

Since both conditions are met, we can use the normal approximation to find the probability.

First, we need to find the mean and standard deviation of the sampling distribution of sample proportions:

mean = np = 81 * 0.5 = 40.5
standard deviation = sqrt(np(1-p)) = sqrt(81 * 0.5 * 0.5) = 4.5

Next, we need to standardize the value of x:

z = (x - mean) / standard deviation
z = (46 - 40.5) / 4.5 = 1.22

Finally, we can use a standard normal table or calculator to find the probability:

P(z ≥ 1.22) = 0.1118

The survey randomly selected students nationwide if they traveled outside the country for spring break and a 99% confidence interval which is 753 students.

The formula for a confidence interval for a proportion is:

CI = p ± z*sqrt((p*(1-p))/n)

where p is the sample proportion, n is the sample size, and z is the critical value from the standard normal distribution corresponding to the desired confidence level.

In this case, the confidence interval is given as (0.0994, 0.1406), which means:

p = (0.0994 + 0.1406) / 2 = 0.1200

The critical value for a 99% confidence interval is z = 2.576.

Substituting these values into the formula and solving for n, we get:

0.0206 = 2.576*sqrt((0.12*(1-0.12))/n)

Squaring both sides and solving for n, we get:

n = (2.576² * 0.12 * 0.88) / (0.0206²) = 752.3

Answer: The amount of money you would have in 5 years if you could save your entire salary with a 1.2% increase every year would be $87,357.41.

Explanation:

The initial term, a₁, is $74,000, and the common ratio, r, is 1 + 1.2% = 1.012. To find the sum of the first 5 terms, we use the formula for a finite geometric series:

S₅ = a₁(1 - r⁶)/(1 - r)

Plugging in the values, we get:

S₅ = $74,000(1 - 1.012⁵)/(1 - 1.012) = $87,357.41 (rounded to the nearest cent)

Therefore, if you save your entire salary, you would have approximately $87,357.41 in 5 years with a 1.2% increase every year.

Jerome will need approximately 138.72 square meters of grass seed to cover his lawn.

To find the area that the grass seed needs to cover, we first need to find the area of the entire lawn. Let's assume that the lawn is rectangular in shape.

Jerome hasn't given us the dimensions of the lawn, so let's say that it measures 10 meters by 15 meters. Therefore, the area of the entire lawn would be:

10 meters x 15 meters = 150 square meters

Now we need to subtract the area of the pool from the area of the entire lawn.

The pool measures 4 5/6 meters by 2 1/3 meters, which we can convert to improper fractions:

4 5/6 = (4 x 6 + 5) / 6 = 29 / 6
2 1/3 = (2 x 3 + 1) / 3 = 7 / 3

So the area of the pool would be:

29/6 meters x 7/3 meters = 203/18 square meters

To find the area that the grass seed needs to cover, we subtract the area of the pool from the area of the entire lawn:

150 square meters - 203/18 square meters

To subtract these two values, we need to get a common denominator:

150 square meters = (150 x 18) / 18 = 2700/18 square meters
203/18 square meters = 203/18 square meters

So the area that the grass seed needs to cover would be:

2700/18 square meters - 203/18 square meters = 2497/18 square meters

We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 1:

2497/18 square meters ≈ 138.72 square meters

Therefore, Jerome will need approximately 138.72 square meters of grass seed to cover his lawn, excluding the area around the pool.

distance = speed × time = (s + c) × 3

We know that this distance is 72 km, so we can write:

(s + c) × 3 = 72

Simplifying this equation, we get:

s + c = 24

Similarly, when the ship is traveling against the current, the effective speed is (s - c). (The difference between the speeds). Therefore, in 4 hours, the ship can travel a distance of:

distance = speed × time = (s - c) × 4

We know that this distance is also 72 km, so we can write:

(s - c) × 4 = 72

Simplifying this equation, we get:

s - c = 18

We now have two equations:

s + c = 24 ; s - c = 18

We can solve for s and c by adding these two equations:

2s = 42

Therefore, s = 21 km/h.

Substituting this value of s into one of the equations above, we can solve for c:

s + c = 24

21 + c = 24

c = 3 km/h.

Therefore, the speed of the ship in still water is 21 km/h, and the speed of the current is 3 km/hs
