How many non-identical triangles can be made using
these side lengths: 4 cm, 8 cm, and 14 cm?
With side lengths of 4, 8, and 14 cm, only one non-identical triangle can be formed.
This is due towards the triangle inequality theorem, which stipulates that the total of any two triangle sides must be bigger than the third side. In this instance, 4 cm plus 8 cm equals 12 cm, that is smaller than 14 cm.
A triangle cannot be formed with these side lengths since they do not meet the triangle inequality theorem. To elaborate, a triangle is created by joining three line segments to create a closed form with three angles.
These line segments' lengths are referred to as the triangle's sides. The total of both sides must be higher than the length of the third one to qualify for a triangle to be present. The triangle inequality hypothesis is what this states.
It is impossible to build a triangle with the side lengths of 4 cm, 8 cm, and 14 cm since the sum of the two shorter sides (4 cm + 8 cm = 12 cm) is less than the length of the longest side (14 cm). Hence, One non-identical triangle can be made.

SHOW ALL YOUR WORK
These are answers of asked question.
A. To factor out the Greatest Common Factor (GCF) of the expression 3t^4 - 6t^3 - 9t + 12, we need to identify the highest power of t that can be factored out. In this case, the GCF is 3t. So we can rewrite the expression as follows:
3t^4 - 6t^3 - 9t + 12 = 3t(t^3 - 2t^2 - 3) + 3t(4)
The GCF, 3t, is factored out from the first two terms, leaving us with t^3 - 2t^2 - 3. The last term, 12, is divisible by 3t, so it becomes +3t(4). Therefore, the factored form of the expression is:
3t(t^3 - 2t^2 - 3) + 3t(4)
B. To factor the expression g^2 - 5g - 14 using the Distributive Method, we look for two numbers whose product is -14 and whose sum is -5 (the coefficient of the middle term). In this case, -7 and +2 satisfy these conditions. So we can rewrite the expression as follows:
g^2 - 5g - 14 = (g - 7)(g + 2)
Using the Distributive Property, we multiply (g - 7) by (g + 2) to verify the factoring:
(g - 7)(g + 2) = g(g) + g(2) - 7(g) - 7(2) = g^2 + 2g - 7g - 14 = g^2 - 5g - 14
Therefore, the factored form of the expression is:
(g - 7)(g + 2)
C. To factor the expression r^2 - 64, we can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). In this case, a = r and b = 8, since 8^2 = 64. So we can rewrite the expression as follows:
r^2 - 64 = (r + 8)(r - 8)
Using the difference of squares formula, we can multiply (r + 8) by (r - 8) to verify the factoring:
(r + 8)(r - 8) = r(r) - r(8) + 8(r) - 8(8) = r^2 - 8r + 8r - 64 = r^2 - 64
Therefore, the factored form of the expression is:
(r + 8)(r - 8)
D. To factor the expression 9p^2 - 42p + 49, we look for two numbers whose product is 49 and whose sum is -42 (the coefficient of the middle term). In this case, -7 and -7 satisfy these conditions. So we can rewrite the expression as follows:
9p^2 - 42p + 49 = (3p - 7)(3p - 7)
Using the Distributive Property, we multiply (3p - 7) by (3p - 7) to verify the factoring:
(3p - 7)(3p - 7) = 3p(3p) - 3p(7) - 7(3p) - 7(7) = 9p^2 - 21p - 21p +

Last season joao scored a goal in 3/5 or 60% of the soccer games. use this experimental probability to determine the number of games he will score a goal this season, if he plays in 10 games
If Joao scored a goal in 60% of the soccer games last season, then we can expect him to score a goal in about 60% of the games he plays this season.
So, if Joao plays in 10 games this season, we can estimate that he will score a goal in approximately 60% of those games.
To calculate the actual number of games he is expected to score a goal in, we can use the formula:
Expected number of goals = Total number of games x Probability of scoring a goal
Plugging in the numbers, we get:
Expected number of goals = 10 x 0.6 = 6
Therefore, based on the experimental probability from last season, we can estimate that Joao will score a goal in around 6 games out of the 10 he plays this season.

a laundromat has 5 washing machines. a typical machine breaks down once every 5 days. a repairer can repair a machine in an average of 2.5 days. currently, three repairers are on duty. the owner of the laundromat has the option of replacing them with a superworker, who can repair a machine in an average of 5 6 day. the salary of the superworker equals the pay of the three regular employees. breakdown and service times are exponential. should the laundromat replace the three repairers with the superworker?
Replacing three repairers with a superworker would be cost-effective for the laundromat as the expected repair time would increase and lead to more downtime for the machines.
To determine if the laundromat should replace the three repairers with the superworker, we need to compare the expected repair time under each scenario.
With three repairers, the expected time to repair a machine is the sum of the expected time until a machine breaks down and the expected time for a repairer to fix it
E(time with three repairers) = 5 + 2.5/3 = 6.167 days.
With the superworker, the expected time to repair a machine is
E(time with superworker) = 5/6 = 0.833 days.
Therefore, on average, it takes much less time to repair a machine with the superworker than with three repairers. Since the salary of the superworker is equal to that of three repairers, the laundromat should replace the three repairers with the superworker. It is also more cost-effective.

In a recent Game Show Network survey, 30% of 5000 viewers are under 30. What is the margin of error at the 99% confidence interval? Using statistical terminology and a complete sentence, what does this mean? (Use z*=2. 576)
Margin of error:
Interpretation:
The margin of error at the 99% confidence interval is 1.39%. Interpretation: we can be 99% confident that the true proportion of viewers under 30 in the population falls within the range of 30% ± 1.39%.
To calculate the margin of error at the 99% confidence interval, we can use the formula:
Margin of error = z* × √(p × (1 - p) / n)
where z* is the critical value (2.576 for a 99% confidence interval), p is the sample proportion (0.30), and n is the sample size (5000).
Margin of error = 2.576 × √(0.30 × (1 - 0.30) / 5000) ≈ 0.0139 or 1.39%
The interpretation of this result is that we can be 99% confident that the true proportion of viewers under 30 in the population falls within the range of 30% ± 1.39%. In other words, if we were to conduct the survey multiple times, we would expect the proportion of viewers under 30 to fall within this interval 99 out of 100 times. This information is useful for understanding the level of uncertainty in the survey results and can help guide decision-making based on the findings.

based on the table, which function models this situation?
The function that models this situation is f(n) = -3n + 24.
To find the function, we need to analyze the relationship between the number of meals dispensed (n) and the amount of pet food remaining (f(n)).
1. Observe the change in f(n) when n increases by 1 meal. From n=1 to n=3, f(n) decreases from 21 to 15, a change of -6. From n=6 to n=7, f(n) decreases from 6 to 3, a change of -3.
2. The decrease in f(n) is not constant, so the function is not linear. However, the decrease becomes smaller as n increases.
3. Consider the average rate of change in f(n) per meal: (-6/2) = -3, (-3/1) = -3.
4. Since the average rate of change is constant, the function is linear.
5. The function has the form f(n) = -3n + b. To find b, plug in the value of n and f(n) from the table: 21 = -3(1) + b, which gives b = 24.

The answer for the derivative of m(x) is:
m'(x) = -10x(x^2 – 9)^(3/2) - 15x^3(x^2 – 9)^(1/2)
This is the final result after applying the product rule and the chain rule.
By use the product rule and the chain rule how we find the derivative?We can use the product rule and the chain rule to find the derivative of the function
First, let's break down the function as follows:
[tex]m(x) = -5x^2 · V(x^2 – 9)^3[/tex][tex]= -5x^2 · (x^2 – 9)^3/2[/tex]
Using the product rule, we have:
[tex]m'(x) = [-5x^2]' · (x^2 – 9)^3/2 + (-5x^2) · [(x^2 – 9)^3/2]'[/tex]Taking the derivative of the first term:
[tex][-5x^2]' = -10x[/tex]Taking the derivative of the second term using the chain rule:
[tex][(x^2 – 9)^3/2]' = (3/2)(x^2 – 9)^(3/2-1) · 2x[/tex][tex]= 3x(x^2 – 9)^(1/2)[/tex]
Putting it all together:
[tex]m'(x) = -10x · (x^2 – 9)^(3/2) + (-5x^2) · 3x(x^2 – 9)^(1/2)[/tex][tex]= -10x(x^2 – 9)^(3/2) - 15x^3(x^2 – 9)^(1/2)[/tex]
To compute the derivative of a function, we need to apply the rules of differentiation, which include the product rule and the chain rule. In this case, we have a product of two functions, [tex]-5x^2[/tex] and [tex]V(x^2 – 9)^3[/tex], where V represents the square root. We apply the product rule to differentiate the two functions.
The product rule states that if we have two functions, u(x) and v(x), then the derivative of their product, u(x) · v(x), is given by u'(x) · v(x) + u(x) · v'(x). We use this rule to differentiate the two terms in the product.For the first term, [tex]-5x^2[/tex], the derivative is straightforward and is simply -10x.
For the second term, [tex]V(x^2 – 9)^3[/tex], we need to use the chain rule because the function inside the square root is not a simple polynomial. The chain rule states that if we have a function g(u(x)), where u(x) is a function of x, then the derivative of g(u(x)) is given by g'(u(x)) · u'(x). In this case, we have [tex]g(u(x)) = V(u(x))^3[/tex], where [tex]u(x) = x^2 – 9[/tex]. We need to apply the chain rule with [tex]g(u) = V(u)^3[/tex] and [tex]u(x) = x^2 – 9[/tex].
To apply the chain rule, we first take the derivative of the function [tex]g(u) = V(u)^3[/tex] with respect to u. The derivative of [tex]V(u) = u^(1/2[/tex]) is [tex]1/(2u^(1/2))[/tex].

The volume of the cone to the nearest tenth is 263.8 cm^3.
What is the volume, rounded to the nearest tenth, of a cone with a radius of 6 centimeters and a height of 7 centimeters?To find the volume of the cone, we first need to use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.
We are given that the radius is 6 centimeters and the height is 7 centimeters, so we can substitute these values into the formula.
The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.
Using the given values, we can plug them into the formula and solve:
V = (1/3)π(6 cm)^2(7 cm)
V ≈ 263.7 cm^3
Rounding this to the nearest tenth gives us the final answer of 263.8 cm^3, which is option (C).

To integrate f(x, y, z) = ~ over the region ? consisting of the points (2, Y, 2)
such that
•0≤o≤1,
•0≤y≤2,and
• 0 ≤ 2 ≤ 3x + 4y.
If we want to use the bounds of integration, what kind of integration would we use?
We first integrate with respect to z from 2 to (3x + 4y), then with respect to y from 0 to 2, and finally with respect to x from 0 to 1.
To integrate the given function over the region, we would use triple integration with the bounds of integration as follows:
∫ from 0 to 1 ∫ from 0 to 2 ∫ from 2 to (3x + 4y) f(x, y, z) dz dy dx
This is because the region is defined by the inequalities 0 ≤ x ≤ 1, 0 ≤ y ≤ 2, and 0 ≤ z ≤ (3x + 4y).
Therefore, we first integrate with respect to z from 2 to (3x + 4y), then with respect to y from 0 to 2, and finally with respect to x from 0 to 1.

You pick a card at random.
What is P(even or prime)?
Write your answer as a percentage
Probability of picking an even or prime card at random is approximately 88.89%.
To find the probability of picking an even or prime card at random, we first need to identify the possible cards that meet these conditions.
In a standard deck of cards, there are 52 cards, but we only consider the numerical values, which are 2-10 for each of the four suits (hearts, clubs, spades, and diamonds).
Even numbers: 2, 4, 6, 8, 10
Prime numbers: 2, 3, 5, 7
Combining the even and prime numbers, we have: 2, 3, 4, 5, 6, 7, 8, 10. Note that 2 appears only once in the combined list.
Now we find the probability by dividing the number of favorable outcomes (even or prime numbers) by the total number of possible outcomes (cards numbered 2-10).
P(even or prime) = (Number of even or prime cards) / (Total number of cards from 2-10)
P(even or prime) = 8 / 9
To express the probability as a percentage, multiply by 100:
P(even or prime) = (8 / 9) × 100 ≈ 88.89%
So, the probability of picking an even or prime card at random is approximately 88.89%.

Given square ertn, what is the length of nt?
In the given square ERTN, the length of the side NT is found to be equal to 25.
The square ERTN has ER = 5x and RT = 10x - 25. Because it is a square, the sides will be equal in magnitude. So, we can write,
Length of ER = Length of RT
5x = 10x - 25
5x = 25
x = 25/5
x = 5
So, the length of ER will be 5(5) = 25 and the length of RT will be 10(5)-25 = 25.
So, finally the length of NT would also be equal to 25.

A triangle has side lengths 6 cm, 7 cm, and √13 cm. Is this triangle a right triangle? Do these side lengths form a Pythagorean triple? Explain.
A triangle with side lengths 6 cm, 7 cm, and √13 cm is right triangle and the side lengths form a Pythagorean triple.
To determine if the triangle with side lengths 6 cm, 7 cm, and √13 cm is a right triangle and if these side lengths form a Pythagorean triple, we'll use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Identify the longest side. In this case, it's the side with length 7 cm.
Check if the Pythagorean theorem holds true for these side lengths:
(6 cm)² + (√13 cm)² = (7 cm)²
Calculate the squares of the side lengths:
(6 cm)² = 36 cm²
(√13 cm)² = 13 cm²
(7 cm)² = 49 cm²
Check if the sum of the squares of the two shorter sides equals the square of the longest side:
36 cm² + 13 cm² = 49 cm²
Compare the results:
49 cm² = 49 cm²
Since the equation holds true, the triangle is indeed a right triangle, and the side lengths 6 cm, 7 cm, and √13 cm form a Pythagorean triple.

First derive a recurrence relation giving on for na 2 in terms of co or cy (or both). Then apply the given initial conditions to find the values of co and Cq. Next determine cn (in terms of n) and, finally, identify the particular solution in terms of familiar elementary functions. y"' + 4y = 0; y(0) = 0, y'(O) = 1 = The recurrence relation is on +2 for n 20. (Type an expression using n, cn, and Cn+1 as the variables.) and C1 = The constants are co = (Type integers or fractions.) The explicit formula for the coefficients is c2n and C2n + 1 for n 20. The particular solution in terms of elementary functions is y(x) =
The given differential equation is y"' + 4y = 0. To derive a recurrence relation, we assume that the solution has the form y = e^rx.
Substituting this in the differential equation, we get the characteristic equation r^3 + 4 = 0. Solving this, we get three roots r = -2i, 2i, 0.
So, the general solution is y = c1cos(2x) + c2sin(2x) + c3. Using the initial conditions y(0) = 0 and y'(0) = 1, we get c1 = 0 and c2 = 1/2.
Therefore, the solution is y = 1/2sin(2x) + c3.
Now, we can find the recurrence relation by writing c3 in terms of c2 and c1. We have c3 = y(0) - (1/2)sin(0) = 0. So, the recurrence relation is cn+2 = -4cn.
Using the initial conditions, we have c1 = 0 and c2 = 1/2. Therefore, the explicit formula for the coefficients is cn = (1/2)(-4)^n-2 for n ≥ 2.
Finally, the particular solution can be found by adding the general solution to the homogeneous solution. Since the roots are imaginary, the particular solution will have the form y = Acos(2x) + Bsin(2x).
Substituting this in the differential equation, we get A = 0 and B = -1/8.
So, the particular solution is y = -1/8sin(2x).
Therefore, the final solution in terms of familiar elementary functions is y = (1/2)sin(2x) - (1/8)sin(2x) = (3/8)sin(2x).
