Step-by-step explanation:

A function is continuous at x is

Limit as x approaches c= f(c).

Step 1: Find f(4).

4 is defined for 2x-1 so plug in. 4 for x.

[tex]2(4) - 1 = 7[/tex]

Note that what we just calculated was not only f(4) but also the left sided limit of f(x).

Step 2: Make sure the left sided and right sided limit are equal to 7.

[tex]a + 5x = 7[/tex]

Plug in 4 for x

[tex]a + 5(4) = 7[/tex]

[tex]a = - 13[/tex]

The height of the triangle FGH is equal to 51 units.

Triangle FGH is an equilateral triangle, thus we understand that each of its sides is identical.

Every side's length is specified as 34√3 units.

In order to split HF into two equivalent halves, use a perpendicular bisector. This implies,

34√3/2=17√3

By using the Pythagorean theorem, which states that the total of a triangle's two sides matches the square of its hypotenuse, we may determine the height.

a²+b²=c²

Here, a=17√3

b=height &

c=34√3

Therefore, from the above equation, we can say,

b²=c²-a²

⇒b²=(34√3)²-(17√3)²

⇒b²=([tex]34^{2}*3[/tex])-([tex]17^{2} *3[/tex])

⇒b²=3468-867

⇒b²=2601

⇒b=[tex]\sqrt{2601}[/tex]

⇒b=51 units

Hence, it is concluded that the height of the triangle is (c)51 units.

The constructed bisector of line segment given below in the image.

Process to construct the bisector of a line segment :

Step 1 : Make the compass length ( the distance between the pointed leg and the pencil leg) slightly greater than half the length of the line segment OP. Place the point of the compass on O. Make arcs above and below the line segment OP.

Step 2 : Using the same compass length as same as the previous one, place the point of the compass on P. Make arcs above and below line segment OP. These arcs must intersect the arcs made in previous step.

Step 3 : Connect the points where the arcs intersect. Label the line segment MN and the point where the line intersects OP, Q.

Step 4 : Line segment MN bisects line segment OP at midpoint Q.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The principal value of sin⁻¹(1) is 90°.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The principal value of sin⁻¹(1) is,

θ = Sin⁻¹(1)

θ = 90°

Hence, the principal value of sin⁻¹(1) is 90°.

The figure showing the construction is given below.

Steps for the construction of a circle through three points not on a straight line are as follows:

1. To create two lines, connect the points.

2. Create the line's perpendicular bisector.

3. Create the opposite line's perpendicular bisector.

4. The circle's center is where they intersect.

5. Draw your circle by placing the compass on the center point and adjusting its length to reach any point.

What happens if the points are parallel?

The circle traveling through all three points will have an infinite radius if the three points are collinear, or all situated on a straight line. Therefore, a practical circle cannot traverse three collinear locations. The two radii would be parallel and would never come together at a center if you tried the construction. We may claim that they do cross mathematically but at infinity.

Hence, after following the steps we obtain the circle.

Answer:

x = 90

Step-by-step explanation:

The other unlabled angle in the triangle forms a 180 degree angle with 130 degrees (because they make a straight line). So it can be found by subtracting 130 from 180, which equals 50.

The sum of all the angles in a triangle is 180.

180 - 50 - 40 = x

90 = x

Hello! My name is Galaxy and I'll be helping you solve this problem. We can split this problem into two steps. Them being Theory and Solving.

I'll go ahead and start with the Theory.

We can start off by looking at the image you've provided, we can see a triangle that has 2 angles given of a triangle, and an exterior angle of the triangle.

This being said, we can apply the Exterior Angle Theorem.

We can now begin to solve for the missing angle.

We can begin to solve by using our given angles to find the third angle.

According to the Exterior Angle Theorem, we know that the unknown angle along with the [tex]40[/tex]° angle must add up to the [tex]130[/tex]° angle.

Therefore, we can solve for [tex]x[/tex],

[tex]x+40=130\\x=130-40\\x=90[/tex]

After this, we know that angle [tex]x[/tex] is equal to 90°.

Cheers,

Answer:

111

Step-by-step explanation:

555÷5=111
and just to check, 5×111=555

Answer:

555 divided by 5 = 111

Step-by-step explanation:

This is common knowledge. The 5 in the hundreds place is divisible by 5 to get a quotient of 1. The 5 in the tens place is also divisible by 5 to get a quotient of 1 and the same is equally true for the 5 in the ones place.

Hence, the quotient of 555/5 = 111

The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs

If 1 package of brownies is bought

15 + 12c = 75

12c = 75 - 15

12c = 60

c = 60/12

c = 5 packs

If 9 packages of brownies are bought

Answer:

Math and Writing

Step-by-step explanation:

Well if we add up all the people we get (9 + 3 + 5 + 3 + 1) = 21. Half of that is 10.5 so the sum of the two subjects must be at least 11. The amount of people that like Math and Writing is 11 people so the two subjects that more than half the class like are Math and Writing.

Answer:

Math and Writing

Step-by-step explanation:

Number of students who like each subject:

Total number of students = 9 + 3 + 5 + 3 + 1 = 21

Half of 21 = 21 ÷ 2 = 10.5

Therefore, more than half the class would be > 10.5 students

Total number of students who like:

Therefore, the only combination of subjects that more than 10.5 students like is Math and Writing as 12 > 10.5

The drag phase you have given the interference would be a positive x-axis.

As Sally determines the angle of rotation, since it is π, she lies on the negative x-axis.

The first block then should be the negative x-axis if r is positive and on the positive x-axis if r is negative.

It is a phenomenon in which two or more waves superimpose to form a resultant wave of greater or lower amplitude.

My other reason for changing the dragged phase would be as they used the word, therefore, in the last sentence.

Which value of x would make triangle ΔSUV is congruent to triangle ΔTUM by HL? Options are 2 3 4 5

The figure is shown below.

The correct option is Option D: the value of x is 5.

Triangles are congruent if the triangles are of the same size and shape. If triangles are congruent the corresponding length of the sides is the same.

Here given that triangle ΔSUV is congruent to triangle ΔTUM.

By the property of the congruent triangle, as triangle ΔSUV and ΔTUM are congruent the corresponding sides are also same.

ΔSUV ≅ΔTUM

⇒ VS≅WT

Given in the question

VS= 2x+9

WT= 4x-1

from above it is clear that

VS=WT

⇒ 2x+9=4x-1

⇒4x-2x=9+1

⇒2x=10

⇒x=10/2

⇒x=5

Therefore the correct option is Option D: the value of x is 5.
