Answer:

x=10

Step-by-step explanation:

set the 2 equations equal to each other

25=2x+5     -> subtract 5

20=2x         -> divide by 2

10=x            ->answer!

Hope that helps!

Answer:

x = 10

Step-by-step explanation:

f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.

2x + 5 = 25

2x = 20

x = 10

Plug in what you got for x to check if it is right

2(10) + 5 = 25

20 + 5 = 25

25 = 25

The nurse should teach the parents to administer 2.5 teaspoons of the acetaminophen liquid suspension per dose.

The prescribed dosage of acetaminophen is 300 mg every 4 hours as needed. The liquid suspension provides 120 mg of acetaminophen per 5 mL (1 teaspoon). To determine the number of teaspoons required for the prescribed dosage, we can set up a proportion:

120 mg / 5 mL = 300 mg / x mL

Cross-multiplying, we get:

120 mg * x mL = 5 mL * 300 mg

Simplifying, we have

120x = 1500

Dividing both sides by 120, we find:

x = 1500 / 120 = 12.5 mL

Since there are 5 mL (1 teaspoon) in each dose, we can convert 12.5 mL to teaspoons:

12.5 mL / 5 mL = 2.5 teaspoons

Therefore, the nurse should teach the parents to administer 2.5 teaspoons of the acetaminophen liquid suspension per dose to ensure the child receives the prescribed dosage of 300 mg.

Answer:

To experimentally verify that the base angles of an isosceles triangle are equal, we will need two isosceles triangles of different sizes.

Materials needed:

Two sheets of paper

Ruler

Pencil

Protractor

Scissors

Experiment:

Draw a large isosceles triangle on one sheet of paper by drawing a straight line at least 20 cm long. Then draw two additional lines from each end of the first line to meet at the top, forming an isosceles triangle. Label the base as "AB" and the other two sides as "AC" and "BC."

Measure and mark the midpoint of the base "AB."

Using a ruler, draw a perpendicular bisector through the midpoint of the base. This line should create two congruent segments.

Measure each angle formed by the intersection of the perpendicular bisector and the two sides of the triangle. Use a protractor to measure these angles.

Repeat steps 1-4 with a smaller isosceles triangle on the second sheet of paper. The smaller triangle should have a base of at least 10 cm and two sides of equal length.

Compare the measurements of the angles of both triangles. If the triangles are truly isosceles, then the two angles opposite the base (ACB) should measure the same in both triangles.

Cut out both isosceles triangles along their outlines.

Fold each triangle along the perpendicular bisector line drawn in step 3 so that the two congruent segments come together.

If the angles opposite the base are indeed equal, then the two sides of each triangle should match up perfectly when folded along the perpendicular bisector. If they do not match up, then the triangles are not truly isosceles.

By repeating this experiment with different sized isosceles triangles, we can verify that the base angles of any isosceles triangle are always equal.

As a rough estimate, 100g of sugar is equivalent to 0.5 cups of granulated sugar.

Conversion is the process of changing units of measurement from one system to another.

In this case, we need to convert 100g of sugar into cups. However, the conversion factor for sugar varies depending on factors such as the type of sugar and how densely it is packed. For instance, powdered sugar is denser than granulated sugar, and so the conversion factor will differ.

In general, one cup of granulated sugar weighs around 200g, which means that 100g of sugar is equivalent to 0.5 cups. However, it is essential to note that this conversion factor is approximate and can vary depending on the quality and type of sugar used.

The equation of the tangent line to the curve y = 2x cos(n) at the point (π, -π) is y = -2x + (2π + 2nπ sin(n) - π), where m = -2 - 2nπ sin(n) and b = 2π + 2nπ sin(n) - π.

To find the equation of the tangent line, we need to find the derivative of y with respect to x, and then evaluate it at the given point (π, -π) to find the slope of the tangent line. Then we can use the point-slope form of a line to find the equation of the tangent line in the form y = mx + b.

Taking the derivative of y with respect to x, we get:

dy/dx = 2cos(n) - 2n x sin(n)

Evaluating this derivative at x = π, we get:

dy/dx |x=π = 2cos(n) - 2n π sin(n)

Substituting x = π and y = -π into the original equation, we get:

-π = 2πcos(n)

cos(n) = -1/2

Since we want the equation of the tangent line at the point (π, -π), we can substitute x = π and y = -π into the point-slope form of a line:

y - (-π) = m(x - π)

Simplifying, we get:

y = m(x - π) - π

Substituting cos(n) = -1/2, we have:

dy/dx |x=π = 2cos(n) - 2n π sin(n) = -2 - 2nπ sin(n)

Setting this equal to the slope of the tangent line, we have:

m = -2 - 2nπ sin(n)

Substituting this value of m into the equation of the tangent line, we have:

y = (-2 - 2nπ sin(n))(x - π) - π

Therefore, the equation of the tangent line is:

y = -2x + (2π + 2nπ sin(n) - π)

We know that segment QS bisects angle TQR because it divides the angle into two congruent angles. By the definition of an angle bisector, we can conclude that angle TQS is congruent to angle SQR.

To prove the congruence of triangles QRS and QTS, we need to establish the following:

1. Segment QS is congruent to segment SQ (QS ≅ SQ).

2. Angle TQR is congruent to angle TSQ (angle TQR ≅ angle TSQ).

To prove that segment QS is congruent to segment SQ (QS ≅ SQ), we can use the property of segment congruence called the reflexive property. According to the reflexive property, any segment is congruent to itself. In this case, segment QS is the same as segment SQ, so we can state that QS ≅ SQ.

Now, let's prove that angle TQR is congruent to angle TSQ (angle TQR ≅ angle TSQ). This congruence can be established through the transitive property of angle congruence. The transitive property states that if two angles are congruent to the same angle, then they are congruent to each other.

We know that angle TQS is congruent to angle SQR (angle TQS ≅ angle SQR) because segment QS bisects angle TQR. Similarly, angle TQS is congruent to angle TSQ (angle TQS ≅ angle TSQ) because angle TQS is the same angle. Therefore, by the transitive property, we can conclude that angle TQR is congruent to angle TSQ (angle TQR ≅ angle TSQ).

Since we have established that segment QS is congruent to segment SQ (QS ≅ SQ) and angle TQR is congruent to angle TSQ (angle TQR ≅ angle TSQ), we can now conclude that triangles QRS and QTS are congruent.

According to the side-angle-side (SAS) congruence criterion, if two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. In our case, segment QS ≅ segment SQ (QS ≅ SQ) and angle TQR ≅ angle TSQ (angle TQR ≅ angle TSQ) satisfy the SAS criterion.

Therefore, by the SAS congruence criterion, we can conclude that triangles QRS and QTS are congruent.

In summary, based on the given information and the properties of congruence, we have shown that segment QS is congruent to segment SQ (QS ≅ SQ) and angle TQR is congruent to angle TSQ (angle TQR ≅ angle TSQ). These congruences satisfy the side-angle-side (SAS) criterion, which allows us to conclude that triangles QRS and QTS are congruent.

The common difference 9 will make 5, x, y, 32 an arithmetic sequence of 5, 14, 23, 32.

It is given that the arithmetic sequence is

5, x, y, 32

We know that for any arithmetic sequence the term aₙ is

aₙ = a + (n - 1)d

where,

a = first term

n = order of the value in the sequence

Since x is the second term

x = 5 + (2 - 1)d

or, x = 5 + d

Similarly,

y = 5 + 2d

32 = 5 + 3d

or, 3d = 27

or, d = 9

Hence, x = 14

y = 5 + 18

= 23

The solution to the pair of simultaneous equation using substitution method is (x,y) = (-2/3, -25/3) or (3, -1)

2x - y = 7 (1)

x² + xy = 6 (2)

From (1)

-y = 7 - 2x

y = 2x - 7 (3)

x² + x(2x - 7) = 6

x² + 2x² - 7x = 6

3x² - 7x - 6 = 0

x = (-b ±√b² - 4ac) / 2a

= -(-7) ± √(-7)² - 4(3)(-6) / 2(3)

= 7 ± √49 - (-72) / 6

= 7 ± √121 / 6

= (7 ± 11) / 6

x = 18/6 or -4/6

x = 3 or -2/3

when x = 3

y = 2x - 7

= 2(3) - 7

= 6 - 7

y = -1

when x = -2/3

y = 2x - 7

= 2(-2/3) - 7

= -4/3 - 7

= (-4-21) / 3

= -25/3

So,

(x,y) = (-2/3, -25/3) or (3, -1)
