What is the relative value of F(x) when the value of x is close to 2 for the function F(x) = 1/x+2, whose graph is shown below?A. A very large numberB. ZeroC. A very small numberD. Either a very large number or a very small number
Answers
Answer:
D. Either a very large number or a very small number
Explanation:
Given the function:
[tex]F(x)=\frac{1}{x+2}[/tex]As can be seen from the graph, the point x=2 is an asymptote of the function.
Thus, the relative value of F(x) when the value of x is close to 2 is either a very large number or a very small number.
Option D is correct.

The measurement of three angles of a triangle are (2x)degrees ,(3x)degrees and (x+30) degrees. What is the value of x?
Answers
We have that the measurement of three angles of a triangle is:
1. Angle 1: 2x degrees.
2. Angle 2: 3x degrees.
3. Angle 3: (x+30) degrees.
We know that the sum of the internal angles of a triangle is equal to 180.
Therefore, to find the value of x, we can proceed as follows:
[tex]\begin{gathered} m\angle1+m\angle2+m\angle3=180^{\circ} \\ \\ 2x+3x+(x+30)=180^{\circ} \end{gathered}[/tex]Now, we can add the like terms as follows:
[tex]\begin{gathered} 2x+3x+x+30^{\circ}=180^{\circ} \\ \\ 5x+x+30^{\circ}=180^{\circ} \\ \\ 6x+30^^{\circ}=180^{\circ} \end{gathered}[/tex]We can subtract 30 degrees to both sides of the equation, and then we have to divide both sides by 6:
[tex]\begin{gathered} 6x+30^{\circ}-30^{\circ}=180^{\circ}-30^{\circ} \\ \\ 6x=150^^{\circ} \\ \\ \frac{6x}{6}=\frac{150}{6} \\ \\ x=25 \end{gathered}[/tex]Therefore, in summary, the value for x is equal to 25.

We are given that Meagan earned $550 at her job in 4 weeks.
We are required to find how many weeks it would take her to make $5000.
First, we need to find the rate at which she works per week as follows:
[tex]\begin{gathered} Since\text{ }4\text{ weeks = \$550} \\ 1\text{ }week=\frac{550}{4} \end{gathered}[/tex]To determine how many weeks it would take her to earn $5000, we need to divide the amount earned after x weeks by the rate as follows:
[tex]\begin{gathered} 1\text{ }week=\frac{550}{4} \\ x\text{ }weeks=5000\div\frac{550}{4}=5000\times\frac{4}{550} \\ =36.36363636\text{ weeks} \end{gathered}[/tex]Hence, the answer is 36.36363636 weeks.

The postulates of congruence for right triangles are
• Hypotenuse-Leg Theorem.
,• Leg-Leg Theorem.
,• Leg-Acute Angle Theorem.
,• Hypotenuse-Acute Angle Theorem.
In this case, we know that sides CE and OQ are congruent. (hypotenuses are congruent)
Angle C is congruent to angle O.
Angle E is congruent to angle Q.
To demonstrate the congruence between triangles we can use Hypotenuse-Acute Angle Theorem since they are congruent between triangles.
We can also use Hypotenuse-Leg Theorem because we have corresponding legs and hypotenuses congruent.
The hypotenuse-acute angle theorem states that two right triangles are congruent if they have congruent hypotenuse and one corresponding pair of acute angles congruent.
The hypotenuse-leg theorem states that two right triangles are congruent if they have congruent hypotenuse and one corresponding pair of congruent legs.

Answers
Given:
The doctor gave the mother of the sick baby 16 fl oz bottle of liquid medicine.
Dosage instructed to give the baby = 30 ml twice a day
a) How many tablespoon is one dose?
Using standard measurements, 1 tablespoon = 15 ml
Since 1 dose is 30 ml, the dose in tablespoon is:
[tex]\frac{30\text{ ml}}{15\text{ ml}}=\text{ 2 tablespoons}[/tex]1 dose is 2 tablespoons
b) Since, 30 ml is to be given 2 times daily, the ml the child will take a day is:

The LCM of a, b is the samllest positive number that is divisible by both a and b:
Prime factorization of 4:
4 divides by 2 ---> 4= 2*2
2 is a primer number, therefore no further factorization is possible.
Prime factorization of 16:
Multiply each factor the greatest number of times it occurs in either 4 or 16

Multiply the numbers: 2*2*2*2 = 16
Adjust fractions based on LCM

Answers
It a popular math theorem, that any natural number can be factored out into prime numbers. For example the number 24 is factored as 2³*3, so its prime factors are 2 and 3.
In this case, we want to factor 124. We start by noticing that 124 is an even number, therefore, the first prime factor we try is 2. Next, we divide 124 by 2. We get
[tex]\frac{124}{2}=62[/tex]which is again an even number. This means that we can again divide by 2. We do so
[tex]\frac{62}{2}=31[/tex]Note that 31 is a prime number. So we can't continue dividing. Then
[tex]124=2\cdot2\cdot31=2^2\cdot31[/tex]So it has 2 different prime factors

Which pairs of figures are congruent? Which pairs are similar?The first question.
Answers
Given the two circles shown in the exercise, you need to remember that, by definition, two figures are congruent when they have the same size and they have the same shape.
In this case, you can identify that the circles have the same diameters (remember that a diameter of a circle is the length that passes through the center of the circle and touch two points on the circumference):
[tex]\begin{gathered} d_1=2units \\ d_2=2units \end{gathered}[/tex]Therefore, these circles have the same shape and size.
By definition, two figures are similar when their corresponding angles are congruent and the ratios of the corresponding sides are proportional.
In this case, since the figures are circles, you know that they both measure 360 degrees. Knowing that they also have the same diameter, you can determine that they are similar too.
Hence, the answer is: They congruent and similar.
