The coordinates of the midpoint of segment FG are (3,-1) which was found using midpoint formula.

When it comes to practical application, the midpoint formula is rather straightforward.

Step 1: Determine the line segment or the two ends.

Step 2: Determine their coordinates.

Step 3: Add the x coordinates of both ends and divide by 2.

Step 4: Adding the y coordinates of both endpoints, divide by 2, and complete the step.

Step 5: As you specify the coordinates of any point, write the values that were acquired in Steps 3 and 4.

Given: Endpoints of a line segment are F(2, -1) and G(-8, -1).

We need to find the coordinates of its midpoint.

Using midpoint formula,

(a,b) = (x₁ + x₂)/2,(y₁ + y₂)/2

       = (2-8)/2,(-1-1)/2

       = 3,-1

So, coordinates are (3,-1)

Therefore, the coordinates of the midpoint of segment FG are (3,-1) which was found using midpoint formula.

The coordinates of the points dividing the line in 5:3 is (3/2, 3)

The section formula gives the coordinates of a point which divides the line joining two points in a ratio, internally or externally.

Given a line LM, passing through points  (-1,-2) and (3,6) a point is dividing it in a ratio of 5:3

According to section formula,

(x, y) = (5*3 - 3*1)/8, (5*6 - 3*2)/8

(x, y) = (3/2, 3)

Hence, The coordinates of the points dividing the line in 5:3 is (3/2, 3)

An equation to describe the relationship between g, the number of gems, and c, the number of chests is; g = 300c

In adventure A, when number of gems is 600, we see that number of chests is 2. Thus;

Rate of gems per chests = 600/2 = 300 g/c

In adventure B, when number of gems is 1500, we see that number of chests is 5. Thus;

Rate of gems per chests = 1500/5 = 300 g/c

In adventure C, when number of gems is 4800, we see that number of chests is 16. Thus;

Rate of gems per chests = 4800/16 = 300 g/c

Thus;

There is a constant rate and we can say that the equation that shows the relationship between the two variables is;

Answer:-0.98

Step-by-step explanation:

You walked 16 blocks in a time of 28 minutes. At this rate you walk 1 block in 1 minute 75 seconds.

In Science, distance can be defined as the amount of ground that is covered (travelled) by a physical object over a particular period of time and speed, irrespective of its direction, starting point or ending point.

Mathematically, the distance traveled by a physical object (body) can be calculated by using this formula:

Distance = speed (rate) × time

Note: Let the variable x represent the halfway distance.

Since it takes the same amount of time to walk each block and halfway there, half of the berries are gone. Therefore, we have the following:

At point x, the number of strawberries that is left is equal to 12 strawberries while the distance after walking 3 more blocks, you still have 5 blocks to go would be given by:

1/2 × x = (3 + 5) = 8

1/2 × x = 8

Distance, x = 8 × 2

Distance, x = 16 blocks.

Now, we can determine the rate at which this person walks a block:

Rate (speed) = 28/16

Rate (speed) = 1.75 minutes.

Answer:

===========================

Answer:

Step-by-step explanation:

Forming the equation,

→ 2x + 3 = -3x + 3

Now the value of x will be,

→ 2x + 3 = -3x + 3

→ 2x + 3x = 3 - 3

→ 5x = 0

→ x = 0/5

→ [ x = 0 ]

Then the value of y will be,

→ y = -3x + 3

→ y = -3(0) + 3

→ y = 0 + 3

→ [ y = 3 ]

Hence, the value of y is 3.

Applying the inscribed angle theorem, we have:

9. B. m∠ABC = 70°

10. F. m∠Z = 54°

11. According to the two-tangent theorem, x is: D. 8 m

An inscribed angle in a circle has a measure that is half of the measure of the intercepted arc, based on the inscribed angle theorem.

The two-tangent theorem states that if two tangents are drawn from a circle to meet at a point outside the circle, the two tangents are equal to each other.

9. Measure of arc AC = 360 - 120 - 100

Measure of arc AC = 140°

m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]

m∠ABC = 1/2(140)

m∠ABC = 70° [option B]

10. Arc XYZ = 2(m∠X) [inscribed angle theorem]

Arc XYZ = 2(126) = 252°

Arc WXY = 360 - arc XYZ

Arc WXY = 360 - 252

Arc WXY = 108°

m∠Z = 1/2(arc WXY) [inscribed angle theorem]

m∠Z = 1/2(108)

m∠Z = 54° [option F]

The fraction that shows the number of hours Saide's dog sleeps every 4 hours in a day is 1/6.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

It should be noted that there are 24 hours in day. Since the dog sleeps for 4 hours in a day, the fraction will be:

= Number of hours slept / Total hours

The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.

We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.

M = m(1 - r)^t

2 = 400(1 - 0.298)^t

0.005 = (0.702)^t

log(0.005) = t*log(0.702)

t = log(0.005)/log(0.702)

The lengths of the major and minor axis are 4√6 and 4√3.

A point on a curve is described by an ellipse if its location is such that the sum of the distances between its two focal points is a constant.

(x−h)²/ b² +(y- k)² /a² = 1

Given:

(x−3)²/ 27+(y+4)² /45=1

The above equation can be compared to the standard equation of an ellipse

(x−h)²/ b² +(y- k)² /a² = 1

where, (h, k) = coordinates of the center of the ellipse

a =  length of the semi major axis

b = length of the semi minor axis

By comparison, we have;

(h, k) = (3, -4)

a = √(24) = 2 x√6

b = √(12) = 2 x√3

and, length of the major axis = 2a

length of the minor axis = 2b

Thus, The length of the major axis is

2x a = 2 × 2 x √6 = 4√6

and, length of the minor axis is

2•b = 2 × 2√3 = 4√3

Convergent Series:

A Convergent Series is a series whose partial sums tend to a specific member is called a limit.

  ∑ 1/2n = 1/2+ 1/4 + 1/8 + 1/16 +........

Given an infinite series ∑₁ ∞ an determine the series is convergence. Recall that we can actually do better with geometric series not only we can determine convergence but also divergence. We can also calculate geometric series.

Suppose we are given a series ∑ aₙ which is not quite a geometric series but becomes a geometric series for sufficiently large n. That is we can find an integer N such that aₙ = aₓⁿ for all n > N. we don't have a general formula for aₙ when n ≤ N. The values of aₙ for small n don't effect Sₙ is convergence or not.

As a moment of fact, we never used the fact that aₙ eventually become geometric. More general ∑aₙ is convergent series, we can add a finite number of terms to the be gaining of this series or remove a finite number of terms from the be gaining of the series without affecting the convergence  of the series. For Example: if ∑aₙ convergence then so does

                        10 + 10¹⁰ + 10 ¹⁰⁰ + 10¹⁰⁰⁰ + ∑aₙ

Similarly, if ∑aₙ convergence then,

                a₁₀₀₀ +a₁₀₀₁ +a₁₀₀₂ + ..... = ∑₁₀₀₀ ∞ aₙ

However, the fact that we are only adding finitely many terms to the series is essential. That is, when it comes to determining convergence of a series ∑aₙ , we can see that only the asymptotic  behavior of ∑aₙ matter, that is, only the behavior of the sequence aₙ as n--- ∞ affects convergence.
