There can be an infinite number of integer values of x possible.

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side for it to be a valid triangle. So, for a triangle with side lengths 15, 47 and  \($\dfrac{x}{2}$\) the condition for the triangle to be valid is:

15 + 47 >\($\dfrac{x}{2}$\)

30 > \($\dfrac{x}{2}$\)

2\times30 > x

x > 60

Since xmust be an integer, the possible values of x are any integer greater than 60. Thus, there can be an infinite number of integer values of x possible.

Answer:

B

Step-by-step explanation:

Answer:

1. 180

2. x = 31

Step-by-step explanation:

1. the sum of the interior angles of every triangle is always 180

2. using what we know from problem 1, we can create an equation:

x + 10 + 2x - 5 + 2x + 20 = 180

add like terms: 5x + 25 = 180

subtract 25 from both sides: 5x = 155

divide both sides by 5: x = 31

The solution to the initial value problem is the function y(t) that satisfies the equation:  t^6 = (1/4)t + 9ln|y|.

To solve the initial value problem, we'll use the method of integrating factors.

Given the initial value problem:

dy/dt = (3/ty) - 2t^5

y(1) = 5

Step 1: Rewrite the equation in the standard form.

dy/dt + (2t^5 - 3/ty) = 0

Step 2: Identify the integrating factor.

The integrating factor (IF) is given by the exponential of the integral of the coefficient of y, which in this case is (2t^5 - 3/ty). Therefore, the integrating factor is:

IF = exp(integral(2t^5 - 3/ty) dt)

Step 3: Calculate the integrating factor.

To find the integral, split it into two parts:

integral(2t^5 - 3/ty) dt = integral(2t^5) dt - integral(3/ty) dt

= (2/6)t^6 - 3ln|y| + C

= (1/3)t^6 - 3ln|y| + C

Now, the integrating factor becomes:

IF = exp((1/3)t^6 - 3ln|y| + C)

= exp((1/3)t^6) * exp(-3ln|y| + C)

= exp((1/3)t^6) * exp(C) / |y|^3

Step 4: Multiply the entire equation by the integrating factor.

exp((1/3)t^6) * exp(C) / |y|^3 * (dy/dt) + exp((1/3)t^6) * exp(C) / |y|^3 * (2t^5 - 3/ty) = 0

Simplifying the equation, we get:

exp((1/3)t^6) * exp(C) / |y|^3 * (dy/dt) + (2t^5 - 3/ty) = 0

Step 5: Integrate both sides of the equation.

∫ exp((1/3)t^6) * exp(C) / |y|^3 dy + ∫ (2t^5 - 3/ty) dt = ∫ 0 dt

The first integral can be simplified by letting u = y^(-3), which means du = -3y^(-4) dy. The limits of integration change accordingly:

∫ exp((1/3)t^6) * exp(C) / |y|^3 dy = ∫ -1/3 exp((1/3)t^6) du

= -1/3 ∫ exp((1/3)t^6) du

The second integral becomes:

∫ (2t^5 - 3/ty) dt = ∫ 2t^5 dt - 3 ∫ 1/y dt

= (2/6)t^6 - 3ln|y| + K1

Combining the integrals, we have:

-1/3 ∫ exp((1/3)t^6) du + (2/6)t^6 - 3ln|y| + K1 = K2

Simplifying further, we get:

-1/3 exp((1/3)t^6) + (1/3)t^6 - 3ln|y| + K1 = K2

Rearranging the terms, we have:

-1/3 exp((1/3)t^6) + (1/3)t^6 - 3ln|y| = K2 - K1

Step 6: Solve for y.

To find the solution for y, we'll use the initial condition y(1) = 5.

When t = 1, we have:

-1/3 exp((1/3)(1)^6) + (1/3)(1)^6 - 3ln|5| = K2 - K1

Simplifying:

-1/3 + 1/3 - 3ln|5| = K2 - K1

-3ln|5| = K2 - K1

Now, substitute K2 - K1 with K:

-3ln|5| = K

Substituting this value back into the equation, we have:

-1/3 exp((1/3)t^6) + (1/3)t^6 - 3ln|y| = -3ln|5|

Rearranging, we get:

exp((1/3)t^6) = 5 * exp(3ln|y|)

Taking the natural logarithm of both sides:

(1/3)t^6 = ln(5) + 3ln|y|

t^6 = 3ln(5)t + 9ln|y|

Step 7: Solve for y.

We'll use the initial condition y(1) = 5 to find the value of y.

When t = 1, we have:

1^6 = 3ln(5)(1) + 9ln|5|

1 = 3ln(5) + 9ln(5)

1 = 12ln(5)

Simplifying:

ln(5) = 1/12

Substituting this back into the equation:

t^6 = 3(1/12)t + 9ln|y|

t^6 = (1/4)t + 9ln|y|

We can solve this equation numerically to find the value of t.

In summary, the solution to the initial value problem is the function y(t) that satisfies the equation:

t^6 = (1/4)t + 9ln|y|

Please note that the final equation obtained is nonlinear and cannot be solved explicitly for y in terms of t.

Answer:

it is a statistical measure of the relationship between two variables that indicates the extent to which the variables change together in the same or opposite direction. Correlation does not imply causation, meaning that a correlation between two variables does not necessarily mean that one variable causes the other.

Based on this definition, the correct answer is b. Increasing values of X go with either increasing or decreasing values of Y. A correlation exists between two variables when both variables increase or decrease together. This statement captures the idea that correlation can be positive or negative, and that it reflects a linear relationship between two variables.

Step-by-step explanation:

a is wrong because it only describes positive correlation, not negative correlation.

c is wrong because it confuses correlation with consistency. Correlation does not require that higher values of X always go with higher or lower values of Y, only that they tend to do so on average.

d and f are wrong because they assume causation from correlation, which is a logical fallacy.

e is wrong because it contradicts itself. It says that increasing values of X go with increasing values of Y, which is positive correlation, but then it says that a correlation exists when both variables decrease together, which is negative correlation.

If X is correlated with Y, it implies a predictive statistical relationship between X and Y. This correlation can be positive or negative implying respective increase or decrease in values of both variables. But, this correlation doesn't prove causation.

If X is correlated with Y, it indicates a statistical relationship between the two variables, X and Y. This relationship can be positive or negative. If it is a positive correlation, as X increases, Y will also increase and similarly, as X decreases, Y will also decrease. Contrarily, in a negative correlation, as X increases, Y decreases and vice versa. However, it is important to understand that correlation does not imply causation. That is, if X and Y are correlated, it does not necessarily mean that changes in X cause changes in Y or vice versa. It only means that they move in a predictable manner relative to each other.

The exterior angle adjacent to the largest interior angle in a triangle with a 2:2:4 angle ratio is 90 degrees.

The exterior angle adjacent to the largest interior angle in a triangle is equal to the sum of the other two interior angles.

Let's call the measures of the angles in the triangle x, x, and 2x. Then,

x + x + 2x = 180 degrees,

so 4x = 180 degrees, and

x = 45 degrees.

The largest interior angle is 2x, or 90 degrees. The exterior angle that is adjacent to this angle is equal to 180 degrees minus the interior angle, which is 180 - 90 = 90 degrees.

So the exterior angle adjacent to the largest interior angle in a triangle with a 2:2:4 angle ratio is 90 degrees.

(a) The vector projection of m onto n is (-35/27, 7/27, -7/27).

(b) A unit vector perpendicular to m and n is approximately (0.251, 0.892, -0.365).

(a) To find the vector projection of m onto n, we can use the formula:

\(proj_{n(m)\) = (m · n / |n\(|^2)\)* n

where "·" denotes the dot product, and |n| represents the magnitude of vector n.

Let's calculate the vector projection:

m · n = (-2 * 5) + (3 * -1) + (6 * 1) = -10 - 3 + 6 = -7

\(|n|^2\) = (\(5^2\)) +\((-1^2) + (1^2)\) = 25 + 1 + 1 = 27

\(proj_{n(m)\) = (-7 / 27) * (5, -1, 1)

             = (-35/27, 7/27, -7/27)

Therefore, the vector projection of m onto n is (-35/27, 7/27, -7/27).

(b) To find a unit vector perpendicular to both m and n, we can take their cross product and then normalize the resulting vector.

m × n = | i j k |

| -2 3 6 |

| 5 -1 1 |

Expanding the determinant:

m × n = (3 * 1 - 6 * -1)i - ((-2 * 1 - 6 * 5)j + (-2 * -1 - 3 * 5)k)

         = (3 + 6)i - (-2 - 30)j + (2 - 15)k

         = 9i + 32j - 13k

To normalize this vector, we divide it by its magnitude:

| m × n | = \(\sqrt{(9^2) + (32^2) + (-13^2)}\)

            = \(\sqrt{(81 + 1024 + 169)}\)

            = \(\sqrt{1274}\)

Therefore, a unit vector perpendicular to m and n is:

u = \((9 /\sqrt{(1274)} , 32 / \sqrt{(1274)} , -13 / \sqrt{(1274)} )\)

Hence, a unit vector perpendicular to m and n is approximately (0.251, 0.892, -0.365).
