SashulF [63]

Answer:

n-2, n-1, n, n+1, n+2, n+3

Step-by-step explanation:

We have to,

→ find the numbers from n-3 to n+4.

Then the numbers are,

→ n-3, n-2, n-1, n, n+1, n+2, n+3, n+4

Hence, there are 6 numbers.

Given the parametric equations x = 7cos θ and y = 5sin θ, which of the following represents the curve and its orientation?
nikitadnepr [17]

We have the following parameters

\begin{gathered} x=7cos\theta \\ y=5sin\theta \end{gathered}

the general equation of a circle with center (0,0) is the following,

x^2+y^2=r^2

Let's use the following tigonometric identity,

sin^2\theta+cos^2\theta=1

solving for cos and sin in the equations we are given,

cos\theta=\frac{x}{7},sin\theta=\frac{y}{5}

replace,

(\frac{y}{5})^2+(\frac{x}{7})^2=1

Since we have two different numbers in the denominator, this is not a circle equation but an elipse, of the form,

\frac{y^2}{a^2}+\frac{x^2}{b^2}=1

where,

a is the vertex and,

b is the covertex

thus, in the x axis, the vertex is 7 and the y-axis the covertex is 5

Now, let's determine the direction by replacing

when Θ = 0 , then x = 7*cos0 = 7*1 = 7 , and y = 5*sin0 = 5*0 = 0

when Θ = 90° or π/2 , then x = 7*cos90° = 7*0 = 0 , and y = 5sin90° = 5*1 = 5

If we draw this, we can see that the direction is counterclockwise as in the bottom right image.

Parallelogram Property: opposite sides are congruent<br><br> Solve for x.
boyakko [2]

Answer:

Value of x = 19

Step-by-step explanation:

We know that in a parallelogram opposite sides are congruent.

So, in the given parallelogram side LM ≅ side NO

So, we can write 2x+2=40

Solving the equation to find value of x

2x+2=40\\2x=40-2\\2x=38\\x=\frac{38}{2}\\x=19

So, value of x = 19
