The candle will burn for approximately 197 more hours before melting entirely.

To calculate the mass lost by the candle after 3 hours of burning, we need to know the rate at which the candle burns. Let's assume the rate is given in grams per hour.

Once we have the rate, we can multiply it by the number of hours to find the mass lost. Let's say the rate is 0.5 grams per hour.

Mass lost after 3 hours = Rate × Time = 0.5 grams/hour × 3 hours = 1.5 grams.

Therefore, the candle lost 1.5 grams of mass after 3 hours of burning.

To estimate how much longer the candle will burn before melting entirely, we need to know the initial mass of the candle and the total mass it can lose before melting. Let's assume the initial mass is 100 grams and the maximum mass loss before melting is 80 grams.

Remaining mass = Initial mass - Mass lost = 100 grams - 1.5 grams = 98.5 grams.

Now, we can estimate the remaining burning time by dividing the remaining mass by the burning rate:

Remaining burning time = Remaining mass / Rate = 98.5 grams / 0.5 grams/hour = 197 hours.

The lines would be parallel to demonstrate that there is no interaction between the independent variables.

Here, it has been mentioned that data from a factorial design is plotted on the graph. We already know that the results of factorial experiments with two independent variables, x and y,  can be represented on the graph where one independent variable is represented on the x-axis and the other is represented by using different colored lines. The y-axis is reserved for the dependent variables.

From the question, we know that there has been no interaction between the independent variables. An interaction means that one variable depended on the other. since that is not happening, It means the lines won't touch each other.

Answer:

-5 hours

Step-by-step explanation:

The correct answer is option a. $7,594.46.

To calculate the amount you would reduce the amount you owe in the first year, we can use the formula for the equal installment of a loan. The formula is:

Installment = Principal / Number of Installments + (Principal - Total Repaid) * Interest Rate

In this case, the principal is $45,000, the number of installments is 5, and the interest rate is 8.5%.

Let's calculate the amount you would reduce the amount you owe in the first year:

Installment = $45,000 / 5 + ($45,000 - $0) * 0.085Installment = $9,000 + $3,825

Installment = $12,825

Therefore, you would reduce the amount you owe by $12,825 in the first year.The correct answer is option a. $7,594.46.

The medians of the triangles are PN = 3 and IM = 5

From the question, we have the following parameters that can be used in our computation:

The triangles are similar

Also, we have

PQ = 9 and IJ = 15

IM = PN + 2

Using the above as a guide, we have the following:

PQ : IJ = PN : IM

This gives

9 : 15 = PN : PN + 2

So, we have

9PN + 18 = 15PN

Evaluate the like terms

6PN = 18

So, we have

PN = 3

Recall that

IM = PN + 2

IM = 3 + 2 = 5

Hence, the lengths are 3 and 5

A condition that is impossible to satisfy has no solution.

Mathematics can be a powerful tool for solving many problems, but there are some issues that can't be solved.

In particular, any condition that is impossible to satisfy, such as the logical statement ‘this statement is false’, has no solution in mathematics. This is because the statement can’t be proven true or false, and so it can’t be solved.

An unsolvable condition is one that cannot be solved using any combination of logical and mathematical steps.

This means that no matter how much time and effort is put in, a solution to the problem cannot be discovered.

To calculate the cost for Design A and Design B, we need to know the size of each design in square inches. Once we have that information, we can multiply the size of each design by the cost per square inch of wood to determine the total cost.

Let's say Design A is 10 inches by 10 inches, which is a total of 100 square inches. To calculate the cost for Design A, we would multiply 100 by 0.15, which gives us a total cost of $15.

Similarly, let's say Design B is 8 inches by 12 inches, which is a total of 96 square inches. To calculate the cost for Design B, we would multiply 96 by 0.15, which gives us a total cost of $14.40.

Therefore, the cost for Design A is $15 and the cost for Design B is $14.40.

In summary, the cost of a wooden design can be calculated by multiplying the size of the design in square inches by the cost per square inch of wood. In this case, we used a cost of 0.15 per square inch and calculated the cost for Design A and Design B. It is important to know the size of the design before calculating the cost.

Answer:

c) x = 1 ± i √29 / 5​

Step-by-step explanation:

assuming we are solving for x we can use the quadratic formula

quadratic formula : \(\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}\)

where the values of a,b and c are derived from the equation

the equation is put in quadratic form : ax² + bx + c

so in 5x² -2x + 6 a = 5 , b = - 2 and c = 6

we then plug these values of a, b and c into the quadratic formula

recall quadratic formula \(\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}\)

a = 5 , b = - 2 , c = 6

\(\frac{-(-2)+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}\)

remove parenthesis at -(-2) to get positive 2 because the negative signs cancel out

\(\frac{2+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}\)

evaluate exponent

\(\frac{2+or-\sqrt{4-4(5)(6)} }{2(5)}\)

multiply -4(5)(6)

\(\frac{2+or-\sqrt{4-120} }{2(5)}\)

subtract 120 from 4

\(\frac{2+or-\sqrt{-116} }{2(5)}\)

multiply 2 and 5

\(\frac{2+or-\sqrt{-116} }{10}\)

because we cant have a negative square root we replace the negative sign with i (which equals -1 )  and add it to the outside of the square root

\(\frac{2+or-i\sqrt{116} }{10}\)

we then simplify  the radical

\(\frac{2+or-2i\sqrt{29} }{10}\)

we then simplify the fraction

2/10 = 1/5 so both 2's cancel out

\(\frac{1+or-i\sqrt{29} }{10}\)

the answer is C

The measure of each interior angle of a decagon is 144 degrees.

1. A decagon is a 10 sided polygon.

2. The sum of the interior angles of any polygon with n sides is (n - 2) * 180 degrees.

3. For a decagon, n = 10, therefore the sum of the interior angles is (10 - 2) * 180 degrees = 8 * 180 degrees = 1440 degrees.

4. Therefore, the measure of each interior angle of a decagon is 1440 degrees / 10 = 144 degrees.

Chord of Contact:-

Equation of the normal chord at any point (at², 2at) of the parabola y² = 4ax is

y + tx = 2at + at³ ....(i)

Look at the attached figure

But if M (x₁, y₁) be it's middle point its equation must be also,

T = S₁

:⟹ yy₁ - 2a (x + x₁) = y₁² - 4ax₁

:⟹ yy₁ - 2ax = y₁² - 2ax₁ .....(ii)

Therefore, from eqs. (i) and (ii) are identical, comparing, them

\( \sf \frac{1}{y_1} = \frac{t}{ - 2a} = \frac{2at + {at}^{3} }{ {y_1}^{2} - 2ax} \\ \\ \sf \: from \: first \: two \: relations \: ,t = - \frac{2a}{y_1} ....(iii)\\ \\ \sf \: from \: first \: two \: relations \: , \: \frac{t}{ - 2a} = \frac{2at + {at}^{3} }{{y_1}^{2} - 2ax_1} \)

The town's population after 10 years is approximately 805,500

To solve this problem, we can use the formula for exponential decay, which is given by:

\(P(t) = P_{0} e^{rt}\)

where P(t) is the population at time t, P₀ is the initial population, r is the annual decay rate as a decimal, and e is the mathematical constant approximately equal to 2.71828.

In our case, the initial population P₀ is 400,000, and the annual decay rate r is 7%. We convert 7% to a decimal by dividing by 100, which gives us r = 0.07.

We want to find the population after 10 years, so we substitute t = 10 into the formula:

\(P(10) = 4,00,000e^{0.07*10}\)

Simplifying this expression, we get:

\(P(10) = 400,000e^{0.7}\)

\(e^{0.7}\) = approximately 2.01375

P(10) = 400,000 * 2.01375

P(10) ≈ 805,500

Therefore, the town's population after 10 years is approximately 805,500.
