Exponents that are positive go to the right. Exponents with negative signs shift to the decimal to the left. A result is stated in scientific notation when it is a power of ten multiplied by a number that is greater than or equal to one but less than ten.

One approach is to fully write out each number after it has been converted from scientific notation, then calculate the total of the two values and translate the result back into scientific notation.

Therefore, The 2, 4, 5, and final 0 in the number 0.2540 are all significant because they come after the decimal point and follow numbers. Scientific notation does not consider exponential digits to be significant; 1.12106 has three significant digits, 1, 1, and 2.

The ASA criterion might be the most appropriate, as it states that two triangles are congruent if two angles and the included side are congruent.

To use a congruence criterion in the given situation, you will need to determine which criterion is most appropriate based on the information provided. There are several congruence criteria that can be used to determine whether two triangles are congruent, including the Side-Side-Side (SSS) criterion, the Side-Angle-Side (SAS) criterion, the Angle-Side-Angle (ASA) criterion, and the Angle-Angle-Side (AAS) criterion.

In this case, the ASA criterion might be the most appropriate, as it states that two triangles are congruent if two angles and the included side are congruent. Given that ∠A=∠C=90∘ and AE=CB, you can use the ASA criterion to conclude that triangles AEB and CED are congruent.

Step-by-step explanation:

For each kilogram of mass, [tex]0.2+4(0.1)=0.6[/tex] milligrams are needed.

Thus, [tex]0.6(10)=6[/tex] milligrams are needed.

This is equal to 4 mL

Answer:

  4 ml

Step-by-step explanation:

You want to know how many mL of medicine is needed for 5 days when the dose is 0.1 mg/kg per day and the concentration is 1.5 mg/mL. The dose on the first day is double that for the rest of the days.

The dose on the first day is equivalent to the dose for 2 days, so we can simply add 1 day to the time period: 5 +1 = 6 days of 0.1 mg/kg/day.

The total amount required will be ...

  (0.1 mg/kg/day) × (10 kg) × (6 days) = 6.0 mg

At a concentration of 1.5 mg/mL, the quantity required is ...

  (6.0 mg)/(1.5 mg/mL) = 4.0 mL

For 5 days, the dog will need 4.0 mL of medicine.

Additional comment

Each day except the first, the dog should receive 2/3 mL of medicine. On the first day, the dog should get 4/3 mL.

The function 4x+7 does not have a horizontal asymptote.

The horizontal asymptote of a function is a horizontal line that the graph of the function approaches as the x-values get larger or smaller.

In this case, the function 4x+7 does not have a horizontal asymptote. This is because the function is a linear function (a function of the form y = mx + b) and all linear functions have a slope (in this case, the slope is 4) but no horizontal asymptotes.

If you are given the graph of a function and you want to find its horizontal asymptotes, you can look at the degree of the function (the highest exponent of the variable). If the degree of the function is less than the degree of the denominator of the function, then the function will have a horizontal asymptote at y = 0.

If the degree of the function is equal to the degree of the denominator, then the function will have a slant asymptote (a line that the graph approaches as the x-values get larger or smaller). If the degree of the function is greater than the degree of the denominator, then the function will not have any horizontal or slant asymptotes.

The equation of the line that passes the points (1, - 6) and (- 5, - 3) is - (1 / 2) · x - 11 / 2.

According to Euclidean geometry, a line can be constructed by setting two points on a plane. By analytical geometry, lines are described by polynomials of the form:

y = m · x + b

Where:

The slope can be found by means of secant line formula:

m = (y₂ - y₁) / (x₂ - x₁)

If we know that (x₁, y₁) = (1, - 6) and (x₂, y₂) = (- 5, - 3), then the equation of the line is:

m = [- 3 - (- 6)] / (- 5 - 1)

m = 3 / (- 6)

m = - 1 / 2

b = y - m · x

b = - 6 - (- 1 / 2) · 1

The answer is True. If two vertical angles are congruent, then two lines cut by a transversal will be parallel.

Vertical angles are angles that are opposite each other and share the same vertex. They are congruent angles, meaning that they have the same measure. When two angles are congruent, the sides of the angles are parallel. This means that the two lines cut by a transversal will also be parallel.

The formula for this is that if two angles are congruent, then the lines cut by a transversal are parallel. This is also known as the Angle-Angle-Angle (AAA) Postulate. This postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. This means that the lines cut by a transversal are parallel.

In other words, if two angles of a triangle are congruent, then the two sides of the triangle that make those angles are parallel. This is because the two angles are congruent, meaning that they have the same measure. Therefore, if two vertical angles are congruent, then two lines cut by a transversal will be parallel.
