Answer:

value of x = 8

Step-by-step explanation:

well here,

line x is parallel to the line measuring 18

so the two triangles are similar to each other

hence ratio of their sides are equal

so 6/ 12 = x/ 16

=》1/2 = x/16

=》 x = 16 / 2

=》 x = 8

i hope u got it

have a nice day

Answer:

x = \(\frac{16}{3}\)

Step-by-step explanation:

The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is

\(\frac{6}{6+12}\) = \(\frac{x}{16}\) , that is

\(\frac{6}{18}\) = \(\frac{x}{16}\) ( cross- multiply )

18x = 96 ( divide both sides by 18 )

x = \(\frac{96}{18}\) = \(\frac{16}{3}\)

The maximum value of p = x + 6y is 14, and it occurs at the corner point (x, y) = (2, 2).

To solve the linear programming problem using the method of corners, we need to examine the corner points of the feasible region defined by the given constraints.

The feasible region is formed by the intersection of the inequalities x + y ≤ 4 and 2x + y ≤ 7, along with the non-negativity constraints x ≥ 0 and y ≥ 0.

By plotting the feasible region or solving the system of equations, we can identify the corner points. In this case, the corner points are (0, 0), (2, 0), (2, 2), and (7/3, 5/3).

Next, we evaluate the objective function p = x + 6y at each corner point. After comparing the values, we find that the maximum value of p is 14, which occurs at the corner point (x, y) = (2, 2).

Answer:

70 stops

Step-by-step explanation:

To find the amount of stops it makes in an hour, do 28 stops ÷ 2 hours, which will give you 14 stops in one hour.

Then do 14 stops × 5 hours, which would give you 70 stops.

Here's the notation if you want to make it look pretty:

 \(5(\frac{28}{2} )=70\)

No, not all square numbers have an odd number of factors. In fact, square numbers can have either an odd or an even number of factors, depending on their prime factorization.

A square number is a number that can be expressed as the product of an integer multiplied by itself. For example, 4 is a square number because it can be written as 2 * 2.

When we analyze the factors of a square number, we find that each factor has a corresponding pair that multiplies to give the square number. For instance, the factors of 4 are 1, 2, and 4. We can see that the pairs are (1, 4) and (2, 2). Thus, 4 has an even number of factors.

However, there are square numbers that have an odd number of factors. Consider the square number 9, which is equal to 3 * 3. The factors of 9 are 1, 3, and 9. In this case, 9 has an odd number of factors.

In conclusion, while some square numbers have an odd number of factors (like 9), others have an even number of factors (like 4). The determining factor is the prime factorization of the square number.

The set is linearly dependent because at least one of the vectors is a multiple of another vector. So, the correct answer is C.

The given vectors are:

v1 = 2v2 = 4v3 = 78 -2 3

To determine whether the vectors V1, V2, and V3 are linearly independent or linearly dependent, we'll use the following method:

We'll create a linear combination of the vectors that has a non-zero answer.

v1 * a + v2 * b + v3 * c = 0

Where a, b and c are scalars that are not all equal to zero.

If the answer is zero, the set of vectors is linearly independent; otherwise, it is linearly dependent.

Therefore, we'll substitute the given values in the above equation.

2a + 4b + 7c = 0

8a - 2b + 3c = 0

If we multiply the first equation by -4 and add it to the second equation, we obtain:-

34c = 0c = 0

This implies that 2a + 4b = 0.

If we divide the first equation by 2, we get: a + 2b = 0

If we multiply the first equation by 3 and subtract it from the third equation, we obtain:

-5a + 5b = 0a = b

Thus, v1 = 2v2.

Since one of the vectors is a multiple of the other, the given set of vectors is linearly dependent.

Therefore, the correct answer is C.

The set is linearly dependent because at least one of the vectors is a multiple of another vector.

Answer:

a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4

b. This conjecture is false. There is a counterexample that would prove this conjecture false.

Step-by-step explanation:

The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.

Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.

If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.

The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.

The correct answer is option B . An equation for the plane is -2x+y+3z=1.

To find an equation of the plane parallel to the plane Q and passing through the point P0, we need to use the following steps:

Step 1: Find the normal vector of plane Q by finding the coefficients of x, y, and z in the given equation.  The normal vector of plane Q has coefficients of x, y, and z equal to -2, 1, and 3, respectively. Therefore, the normal vector is: n = ⟨-2, 1, 3⟩.

Step 2: Use the normal vector and the given point P0 to write the equation of the desired. Since the desired plane is parallel to plane Q, it must have the same normal vector as plane Q. Also, since the desired plane passes through point P0(-2, 0, -1), the equation of the plane can be written as:

-2(x + 2) + 1(y - 0) + 3(z + 1) = 0-2x - 4 + y + 3z + 3 = 0-2x + y + 3z = 1

Therefore, the equation for the plane that is parallel to plane Q and passing through point P0 is -2x + y + 3z = 1. Thus, option B is the correct answer. Answer: B. An equation for the plane is -2x+y+3z=1.

The angle θ1 located in quadrant IV and sin(θ1) is negative.

The angle θ1 located in quadrant IV and sin(θ1) is negative. When an angle is located in quadrant IV, it means that the angle is between 270 and 360 degrees (or between -90 and 0 degrees).

The sin function is negative in quadrants III and IV. Since θ1 is in quadrant IV, sin(θ1) will be negative. This is because sin is defined as the ratio of the opposite side to the hypotenuse in a right triangle. In quadrant IV, the x-coordinate (adjacent side) is positive and the y-coordinate (opposite side) is negative, so sin is negative.

Therefore, we can conclude that the angle θ1 located in quadrant IV and sin(θ1) is negative.

To solve many simultaneous linear equations, use the substitution method in algebra.

The algebraic technique for resolving multiple linear equations at once is called the substitution method. As the name implies, this method involves substituting a variable's value from one equation into another.

The first stage in the substitution approach is to determine any variable's value in terms of the other variable from one equation. If there are two equations, x+y=7 and x-y=8, for instance, we can deduce from the first equation that x=7-y. The substitution approach is applied in this manner as the first stage.

Answer:

4x + 1

Step-by-step explanation:

24x² - 30x - 9 ( factor out 3 from each term )

= 3(8x² - 10x - 3) ← factor the quadratic

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 8 × - 3 = - 24 and sum = - 10

the factors are + 2 and - 12

use these factors to split the x- term

8x² + 2x - 12x - 3 ( factor the first/second and third/fourth terms )

= 2x(4x + 1) - 3(4x + 1) ← factor out (4x + 1) from each term

= (4x + 1)(2x - 3)

then

24x² - 30x - 9 = 3(4x + 1)(2x - 3) ← in factored form

so (4x + 1) is a factor of the expression

(a) The maturity value of the loan is $15,246.33.

(b) The amount of interest paid on the loan is $7,246.33.

To calculate the maturity value of the loan, we can use the formula for compound interest: A = \(P(1 + r/n)^(nt)\), where A is the maturity value, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, the principal amount (P) is $8000, the interest rate (r) is 9%, the loan duration is 9 years, and interest is compounded quarterly, so n = 4. Plugging these values into the formula, we get A = \(8000(1 + 0.09/4)^(4*9)\) = $15,246.33.

To calculate the amount of interest paid on the loan, we subtract the principal amount from the maturity value: Interest = Maturity value - Principal amount = $15,246.33 - $8000 = $7,246.33.
