Explain how to graph the given piecewise-defined function. Be sure to specify the type of endpoint each piece of the function will have and why. f(x)= 3, x + 3, X < 2 25 x < 4 4 – 2x, x 2 4​

Answers

You would graph the equation f(x) = –x + 3 for input values less than 2. There would be an open circle at the point (2, 1) since the domain for the first piece does not include 2. You would then graph a horizontal line at f(x) = 3 for input values between 2 and 4. There would be a closed circle at (2, 3) and an open circle at (4, 3). Last, you would graph f(x) = 4 – 2x for input values greater than or equal to 4. There would be a closed circle at the point (4, –4) since 4 is in the domain of the third piece.

Answer:

HGI=EFG because its the same, its just flipped.

The answer is the opposite of 104°.  The negative inverse of 104° is -104° I think.

HGI is -140°.

EFG is 140°.

Gotcha!
Answer & Explanation:
Angles EGF And HGI are congruent to each other, Which means if EGF is 104 degrees then HGI is 104.
1. The size of HGI is 104 degrees


Angle EGF is 104 degrees, and we are looking to find the size of EFG,
So since E to F is a straight line, we are going to add 104(EGF) to 180, and we have 284.

2. The size of EGF is 284 degrees.


Define:
Congruent: Triangles that have both the same shape and the same size.
Straight line= 180degrees
Scalene triangle: A triangle that has no equal sides.
Isosceles Triangle: a triangle that has two sides the same length.
Equilateral triangle: A triangles all three sides are congruent.

Hope this helps!

The iterative rule for this geometric sequence is [tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]

What is geometric sequence?A unique kind of sequence is a geometric sequence. Every term in the series (aside from the first term) is multiplied by a fixed amount to determine the following term. In other words, we multiply the current phrase in the geometric sequence by a constant term (called the common ratio), Divide the current term in the geometric sequence by the same common ratio to discover the previous term in the geometric sequence. Here is an illustration of a geometric sequence with a common ratio of 2, which is 3, 6, 12, 24, and so on. A geometric sequence's common ratio can be either negative or positive, but it cannot be zero.Given that we are aware that a geometric series has an explicit formula in form[tex]a_{n} =(a_{1} )*r^{n-1}[/tex]where, [tex]a_{n}[/tex]=nth term of geometric sequence[tex]a_{1}[/tex]= 1st term of geometric sequencer=common ratioWe can see that our geometric sequence's first term is. By dividing any number by the number that comes before it in the sequence, let's find the common ratio of our supplied sequence.Since 2 comes before 6 in the given geometric sequence, let's divide 6 by 2.r= 6/3 = 3The common ratio is three, as can be seen.When we use the explicit geometric sequence formula with our values, we will obtain,[tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]

Therefore, The iterative rule for this geometric sequence is [tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]

Answer:

(A) 44.7°

Step-by-step explanation:

Use the law of cosines:

[tex]cos A=(b^2+c^2-a^2)/(2bc)[/tex][tex]cos A=(25^2+31^2-22^2)/(2*25*31)=0.711[/tex]m∠A = arccos(0.711) ≈ 44.7°

Using law of cosines

[tex]\\ \sf\longmapsto cosA=\dfrac{b^2+c^2-a^2}{2bc}[/tex]

[tex]\\ \sf\longmapsto cosA=\dfrac{25^2+31^2-32^2}{2(25)(31)}[/tex]

[tex]\\ \sf\longmapsto cosA=\dfrac{625+961-484}{1550}[/tex]

[tex]\\ \sf\longmapsto cosA=\dfrac{1102}{1550}[/tex]

[tex]\\ \sf\longmapsto cosA=0.7109[/tex]

In the figure below, m 110°, m 68°, and KN bisects LKM. Find JKN.

Answers

Answer:

m<JKN=76º

Step-by-step explanation:

since the angle bisects just divide 68 by 2

m<LKN=34º

then since JKM is the total of all angle measurements

110-68=42

so m<JKL=42º

JKL+LKN=JKN

42+34=76

to check just add the measurements and makes sure that they make 110

so 76+34=110

The value of an angle ∠JKN will be 76 degrees.

What is an angle?

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. In geometry, the ray, line, or segment that divides a given angle into two equal pieces is known as the angle bisector.

Given that In the figure, m 110°, m 68°, and KN bisects LKM.

Since the angle bisects just divide 68 by 2

∠LKN=34º

Then since JKM is the total of all angle measurements

110-68=42

∠JKL=42º

JKL+LKN=JKN

42+34=76 degrees

Therefore, the value of an angle ∠JKN will be 76 degrees.

Answers

The number of players the team can bring to the tournament is 13.

The first step is to determine the total budget for all the players. To do this, subtract the cost of renting the bus from the total money raised.

Budget for all the players = $1158.25 - $836.50 = $321.75

The second step is to determine the number of players that can go for the tournament, divide the total budget by the budget per player.

Number of players that can attend the tournament = $321.75 / $24.75 = 13 players.
