The distance from the sun to the other focus is 5.01 × 10⁹ m.

(a) The distance from the center of an ellipse to a focus is an where a is the semi major axis and e is the eccentricity. Thus, the separation of the foci ( in the case of Earth's orbit ) is;

2ae = 2(1.50 × 10¹¹)(0.0167) = 5.01 × 10⁹ m.

(b) To express this in terms of solar radii, we set up a ratio;

(5.01 × 10⁹)/(6.96 × 10⁸) = 7.2

Thus, we can conclude that the distance from the sun to the other focus is 5.01 × 10⁹ m.

The equation of line is:

y = (5/2) x - 11

Given,

Points (x₁, y₁) = (2, 4) and (x₂, y₂) = (-4, -11)

We can find the slope using the equation for slope

m = (y₂ - y₁) / (x₂ - x₁)

   = (-11 -4) / (-4 -2)

   = -15 / - 6

    = 5/2

We know the slope and a point, so we can use point slope form to make an equation

y-y₁ = m(x-x₁)

y - (-4) = 5/2 (x-2)

Distribute

y+4 = 5/2x – 5/2 x 2

y+4 = 5/2x - 5

Add -4 to each side

y +4 -4 = 5/2x – 5 - 4

y = 5/2x - 11

This is in slope intercept form (y= mx-b)

The maximum​ displacement, the​ frequency, and the time required for one cycle are 1/5 inch, 1/π Hz and π sec.

A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.

Therefore, the instantaneous speed is different from velocity, which is the rate at which the distance traveled along a particular path changes over time. The temporal rate of change of the position vector can also be used to describe velocity.

The equation of the line in standard form of 2y = -4x - 12 is 4x + 2y = -12.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant.

Given the equation 2y = -4x - 12, to write the equation in standard form, arrange the variable(s) in one side and the constant(s) in the other.

2y = -4x - 12

4x + 2y = -12

Let's solve your system by elimination.

7x−4y=2;2x−1y=2

Multiply the second equation by -4, then add the equations together.

(7x−4y=2)

−4(2x−1y=2)

Becomes:

7x−4y=2

−8x+4y=−8

Add these equations to eliminate y:

−x=−6

Then solve−x=−6for x:

−x=−6

−x/−1 = −6/−1

(Divide both sides by -1)

x=6

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

7x−4y=2

Substitute6forxin7x−4y=2:

(7)(6)−4y=2

−4y+42=2(Simplify both sides of the equation)

−4y+42+−42=2+−42(Add -42 to both sides)

−4y=−40

−4y/−4 = −40/−4

(Divide both sides by -4)

Answer: n=-7

Step-by-step explanation:

5n - 7n = 14

(5-7)n=14

-2n=14

-2n/(-2)=14/(-2)

n=14/(-2)

n=-7

The equation is,

→ 5n - 7n = 14

Solving for the value of n,

→ 5n - 7n = 14

→ -2n = 14

→ n = -(14//2)

→ [ n = -7 ]

Thus, the value of n is -7.

The formula for estimating the nth term of an arithmetic sequence is:

a n = a₁ + (n-1)d

The first five terms of a n = -2n + 3 = 1, -1, -3, -5, -7

A succession of numbers merged together to make a sequence exists comprehended as an arithmetic sequence.

A series of numbers named an arithmetic progression or arithmetic sequence (AP) contains a constant difference between the terms.

The formula for estimating the nth term of an arithmetic sequence exists:

a n = a₁ + (n-1)d

The four quantities in the formula exist a n, a₁, n, d.

The first 5 terms are a n = -2n + 3

a₁ = -2 + 3 = 1

a2 = -4 + 3 = -1

a3 = -6 + 3 = -3

a4 = -8 + 3 = -5

a5 = -10+3 = -7
