Which expression can be used to find the value of X?

Solution :

Given that, In triangle MKL, angle K is a right angle.

To find the value of tan M,

As we know by trigonometric ratio, that In a right angled triangle

[tex] tan (\theta)= \frac{opposite }{Adjacent} [/tex]

Here Opposite means opposite side of the angle and adjacent means side adjacent to the angle.

So, [tex] tan M= \frac{KL}{KM} = \frac{15}{8} [/tex]

Hence, Value of [tex] tan M = \frac{15}{8} [/tex] .

Answer:

50&10...

Step-by-step explanation:

This answer details the use of the quadratic formula to solve quadratic equations and the discriminant's role in determining the number of real solutions.

The question involves solving quadratic equations and using the discriminant to determine the number of real solutions. The quadratic formula, \(x = \frac{-b \pm \sqrt[tex]{b^2[/tex] - 4ac}}{2a}\), is a powerful tool in finding the roots of any quadratic equation of the form \([tex]ax^2[/tex]+ bx + c = 0\). The discriminant, \(\Delta =[tex]b^2[/tex] - 4ac\), helps in understanding the nature of the roots without actually solving the equation. If \(\Delta > 0\), there are two distinct real solutions; if \(\Delta = 0\), there is exactly one real solution; and if \(\Delta < 0\), there are no real solutions and instead two complex solutions.

Answer:

Correct Answer: Revolution

Step-by-step explanation:

The expression given to us is: x²+6x

Now, we know that the second term is twice the square root of the first and the last terms. Let us call the last term as [tex] y^2 [/tex]. Thus our given expression will become:

[tex] x^2+6x+y^2 [/tex].

Now, since the middle term is 6x and since we know that the second term is twice the square root of the first and the last terms, therefore,

[tex] 6x=2\times \sqrt{x^2} \times \sqrt{y^2} [/tex]

[tex] 6x=2\times x\times y [/tex]

[tex] \therefore y=3 [/tex] (By dividing both sides by 2x)

Therefore, the missing term is 3.

To prove the identity tan (pi/2-x) = cot x, we can use the identity tan(pi/2-x) = 1/tan x and simplify the expression.

To prove tan (pi/2-x) = cot x, we can use the identity tan(pi/2-x) = 1/tan x. First, rewrite tan(pi/2-x) as 1/tan x. Then, simplify 1/tan x to cot x using the definition of cot x = 1/tan x. Therefore, we have proven that tan (pi/2-x) = cot x.

To prove tan(π/2 - x) = cot x, we use the co-function identity for tangent and cotangent, showing the relation of these functions in complementary angles. This identity confirms that tan(π/2 - x) equals cot x.

To prove the identity tan (π/2 - x) = cot x, we can use a fundamental trigonometric identity. Here's how:

Recall the co-function identity: tan (π/2 - x) = cot x. This identity is derived from the relationship between tangent and cotangent in complementary angles.

Using the identity tan (π/2 - x) = cot x, we know that the tangent of an angle's complement is equal to the cotangent of the angle.

By definition, tan θ (tangent) is the ratio of the opposite side to the adjacent side in a right triangle. For the complementary angle, the roles of the opposite and adjacent sides switch, which aligns with the definition of cot x (cotangent), i.e., the adjacent side over the opposite side.

This proves that tan (π/2 - x) = cot x.

Answer:

I THINK A

Step-by-step explanation:

The graph of a quadratic function, or a parabola, is U or n-shaped and its direction depends on the sign of the coefficient of the x-squared term. The vertex and line of symmetry can be found using formulas based on this coefficient.

The graph of a quadratic function, also known as a parabola, generally takes on a 'U' or 'n' shape. The direction that the 'U' faces depends on the sign of the coefficient, which is the number associated with the x-squared term in the equation. If this coefficient is positive, the graph opens upwards; if it's negative, the graph opens downwards. The vertex (the highest or lowest point on a parabola) can be calculated using the formula -b/2a. The line of symmetry can be found using the equation x = -b/2a.

For example, consider the quadratic function f(x)=x^2. This equation represents a parabola that opens upwards. Its vertex is at the point (0,0) and its line of symmetry is x=0.

Option: B is the correct answer.

B) Traditionalism.

Beat generation was a literary movement that was started by a group of authors and  belongs to the post World War || period.

They started this movement to reject literary formalism and the American culture built on capitalism and materialism.

It has a major impact on both poetry as well as culture in America.

Hence, the Beat generation writers try to defeat in America is:

Traditionalism.

In the given hour, Dale ran 5 miles and Chan ran 2.5 miles.

Let Dale's running miles be represented by the variable D and let Chan's running miles be represented by the variable C.

In-order to compare Dale's running miles to Chan's by using division we get:

[tex] \frac{D}{C}=\frac{5}{2.5} = \frac{2}{1} [/tex]

[tex] D=2C [/tex]

Thus, Dale ran twice the distance Chan ran in the same amount of time of 1 hour.

Equivalently we can say that Chan ran half the distance Dale ran in the same amount of time of 1 hour.

Answer:

He will reach 0.02 hours before me.

Step-by-step explanation:

A we know that,

Speed = Distance ÷ Time

Here we have given that Distance = 50 km

My Speed is 90 km/h

So time taken to complete my trip = Distance ÷ Speed

⇒ My Time = 50 ÷ 90 = 0.55 hours

Also, Speed of my friend is 95 km/h

So time taken to him to complete his trip = Distance ÷ Speed

His Time = 50 ÷ 95 = 0.53 hours

Thus he will reached before me as his speed is fast

He will reach 0.55 - 0.53 = 0.02 hours before me.

Answer:

C) 16 units

Step-by-step explanation:

The length of a leg of the pre-image is 16 units

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image. Dilation comes in two varieties:

Given:

Δ RST was dilated by a scale factor of 1/2

and,  Δ R'S'T' is an isosceles triangle with measurement 8 units.

As, Pre-image =  measure of pre-image x scale factor

So, the measure of pre-image = 8 ÷ 1/2

                                                   = 8 x 2/1

                                                   = 16 units.

Hence, the length of a leg of the pre-image is 16 units

Answer:

Credit card B, because its effective interest rate is about 0.13% less than that of credit card A.

The deal of Credit card A is du to higher interest rate.

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.

Given

APR of credit card A = 25.68% compounded monthly

APR of credit card B = 25.32% compounded daily

other details are same

let principle be 100

time = 1 year

Amount for Credit card A = P[tex](1 + \frac{r}{n})^{n t}[/tex]

where r = rate, t = time, n = time frequency

A = 100[tex](1 + \frac{0.2568}{12})^{12*1 }[/tex]

A = 128.92

amount for credit card B

A = 100[tex](1 + \frac{0.2532}{360})^{360*1 }[/tex]

A = 128.78

Hence amount for both the APR is approx. same so Credit card A is better deal with more interest rate.
