Answer:

both Ella and Ethan jogged 1/6 of the way home.

Step-by-step explanation:

To solve the problem, we need to find the fraction of the distance that each twin jogged.

Let's start with Ella. If she ran 1/3 of the way, walked 1/6 of the way, and jogged the rest of the way, then the fraction of the way she jogged is:

1 - 1/3 - 1/6 = 2/6 - 1/6 - 1/6 = 1/6

So Ella jogged 1/6 of the way home.

Now let's look at Ethan. If he ran 1/2 of the way, walked 1/3 of the way, and jogged the rest of the way, then the fraction of the way he jogged is:

1 - 1/2 - 1/3 = 6/6 - 3/6 - 2/6 = 1/6

So Ethan jogged 1/6 of the way home, which is the same as Ella.

Therefore, both Ella and Ethan jogged 1/6 of the way home.

Applying the secant-secant theorem, the value of x is: 12.

The secant-secant theorem states that if you draw two lines from a point outside a circle that intersect the circle at two different points, then the product of the length of one line segment and the length of the portion of the line outside the circle is equal to the product of the length of the other line segment and the length of its portion outside the circle.

Based on the secant-secant theorem, we have:

EF * ES = ED * EC

Substitute the values:

8(8 + 10) = 9(2x - 17 + 9)

Solve for x:

144 = 18x - 72

144 + 72 = 18x

Average weight= Total weight of 4 sacks / number of sacks

6.5 = (17.5 + x) / 4

cross product

6.5 × 4 = 17.5 + x

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

To calculate the 10% down payment required by the bank, you can use the following formula:

Down payment = 2700 x 10%

                          = $270

To calculate the loan amount, you can subtract the down payment from the total cost of the moped:

Loan amount = 2700 - 270

                      = $2430

To calculate the monthly loan payment, you need to know the interest rate, the loan amount, and the number of months in the loan term. You can use the following formula to calculate the monthly payment:

Monthly payment = (Loan amount x Interest rate) / (1 - (1 + Interest rate)^(-Number of months in loan term))

In this case:

Monthly payment = ($2430 x 8%) / (1 - (1 + 8%)⁻⁶)

Monthly payment = $44.38

The breakdown of each of the 6 payments would be $44.38 per month.

To find the arc length, we use the formula L = rθ, where r is the radius of the circle, θ is the central angle of the arc in radians, and L is the arc length.

Arc length refers to the distance covered along the curved portion of a circle or any other curved shape. It is an important concept in geometry and trigonometry and is used to measure the size of circular arcs, the size of angles, and in many other mathematical applications.

To find the arc length, we need to use the formula for the circumference of a circle and the central angle of the arc.

The circumference of a circle is given by the formula 2πr, where r is the radius of the circle.

The central angle of the arc is given in radians and is defined as the angle between two radii that meet at the endpoints of the arc.

To find the arc length, we use the formula

=> L = rθ,

where L is the arc length, r is the radius of the circle, and θ is the central angle of the arc in radians.

To convert the central angle from degrees to radians, we use the formula θ = (π/180) x degrees, where degrees are the central angle in degrees.

The values of the two limits are lim x->33- g(x) = -15 and lim x->33+ g(x) = -6.

Option (B) is correct.

What is a limit in calculus?

The limits in mathematics describe the behavior of a function as the input approaches a certain value. The symbols for limits are "lim" followed by the variable and the value that the variable is approaching, with an arrow indicating the direction of the approach.

For the given function g(x), we have the following limits:

lim x->33- g(x) = -15.1

This means that as x approaches 33 from below, the value of g(x) approaches -15.1. We can see this from the values in the table, as x gets closer to 33 from below, g(x) gets closer to -15.1.

lim x->33+ g(x) = -6.1

This means that as x approaches 33 from above, the value of g(x) approaches -6.1. We can see this from the values in the table, as x gets closer to 33 from above, g(x) gets closer to -6.1.

So, the values of the two limits are lim x->33- g(x) = -15.1 and lim x->33+ g(x) = -6.1.

Answer:

Jamie has $12.50 of her allowance left if the books cost $2.50 each.

Step-by-step explanation:

To calculate this, first calculate the total cost of the books:

5 books x $2.50/book = $12.50.

Then subtract the cost of the books from the amount Jamie has saved:

$38 - $12.50 = $25.50.

Finally, subtract the cost of the books from the amount Jamie has saved to get the amount she has left:

$25.50 - $12.50 = $12.50.

Answer:

$25.50

Step-by-step explanation:

We know Jamie bought 5 books, each worth $2.50, d. We need to know the cost of all five, so we’ll go ahead and multiply 5 times $2.50 to get $12.50.

Since we know how much the books cost, all we have to do now is subtract the amount she spent from her allowance. $38.00 - $12.50 is 25.50, the amount of money Jamie has left.

An expression  x² - 8x + 5 in the form  (x - a)² - b is:  (x - 4)² - 11

Consider a quadratic expression x² - 8x + 5

To convert this expression into the form (x - a)² - b we us completing the square method.

We know that for a quadratic equation ax² + bx + c = 0, steps of completing the equare method:

1) Write the equation ax² + bx + c = 0 such that c is on the right side.

2) If a ≠ 1, divide the complete equation ax² + bx + c = 0 by 'a' so that the coefficient of x² will be 1.

3) Add the (b/2a)², on both sides.

Comparing expression  x² - 8x + 5 with ax² + bx + c we get,

a = 1, b = -8 and c = 5

the value of the expression (b/2a)² is:

(b/2a)²

= [-8/(2 × 1)]²

= (-8/2)²

= (-4)²

= 16

We add and subtract the value of the expression  (b/2a)² in expression  x² - 8x + 5

So the expression would be,

x² - 8x + 5 + 16 - 16

= x² - 8x  + 16 + 5 - 16       ......(commutative property of addition)

Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )

The distance from A to B is the same as the distance from B to A

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

This formula is used to find the distance between any two points on a coordinate plane or x-y plane

Given data ,

Let the distance between the points on the line be A

Now , the equation will be

Let the first point be P ( -4/3 , 0 )

A function maps an input (or domain) to a unique output (or range). In order for a function to have a domain of all real numbers, it must take any real number as an input and provide a unique output. However, for a function to have a range of all integers, it must be the case that every output is an integer.

Since the real numbers are not countable and the integers are countable, there can be no function that maps every real number to a unique integer.
