Use the law of cosines to find the length of a
Answer:
Step-by-step explanation:
You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:
[tex]\frac{sin55}{175}=\frac{sin42}{a}[/tex] and solving for a:
[tex]a=\frac{175sin42}{sin55}[/tex] so
a = 143.0

The midpoint of AB = ([?],[ ])
Answer:
midpoint of AB = (-1/2 , 0)
Step-by-step explanation:
A(-2 , 1) = (x1 , y1)
B(1 , -1) = (x2 , y2)
midpoint formula:
=(x1 + x2/2 , y1 + y2/2)
=(-2 + 1/2 , 1 + (-1)/2)
=(-1/2 , 0/2)
(-1/2 , 0)

Step-by-step explanation:
Looking at the plot, we can see that the number 27 represents the minimum value while the number 45 represents the upper quartile
Between the minimum value and the upper quartile, there is 75% of all the values on the plot
So, we can conclude that between the numbers 27 and 45, we have 75% of all the data values present.
Kindly note;

Answer:
(A) -3 ≤ x ≤ 1
Step-by-step explanation:
The given function is presented as follows;
h(x) = x² - 1
From the given function, the coefficient of the quadratic term is positive, and therefore, the function is U shaped and has a minimum value, with the slope on the interval to the left of h having a negative rate of change;
The minimum value of h(x) is found as follows;
At the minimum of h(x), h'(x) = d(h(x)/dx = d(x² - 1)/dx = 2·x = 0
∴ x = 0/2 = 0 at the minimum
Therefore, the function is symmetrical about the point where x = 0
The average rate of change over an interval is given by the change in 'y' and x-values over the end-point in the interval, which is the slope of a straight line drawn between the points
The average rate of change will be negative where the y-value of the left boundary of the interval is higher than the y-value of the right boundary of the interval, such that the line formed by joining the endpoints of the interval slope downwards from left to right
The distance from the x-value of left boundary of the interval that would have a negative slope from x = 0 will be more than the distance of the x-value of the right boundary of the interval
Therefore, the interval over which h has a negative rate of change is -3 ≤ x ≤ 1

An aeroplane travels on a bearing of 295o so that it is 200 km west of its starting point. How far has it travelled on this bearing?
please use diagrams to explain
The more accurate value is roughly 220.675583792499 km but even that isn't an exact value.
===============================================
Explanation:
Refer to the diagram below.
The plane starts at point A, which is the origin (0,0)
Directly north is the bearing 0 degrees, which it sometimes written as triple zeros and a degree symbol at the end, so we'd write 000° to mean directly north.
Let's say we face directly north. When turning clockwise (turn toward the east), the bearing angle increases. That means directly east is the bearing 090° and 180° is directly south.
The bearing 270° is directly west. Another 25 degrees gets us to 270+25 = 295°
This plane is facing the northwest direction, as the diagram indicates below (the plane is aimed at point C while it's located at point A initially).
------------
Triangle ABC has the horizontal component AB = 200 km, since we're told that the plane is 200 km west of its starting point (and some unknown distance north of the starting point).
We use the cosine ratio to help determine the hypotenuse length AC
cos(angle) = adjacent/hypotenuse
cos(A) = AB/AC
cos(25) = 200/x
x*cos(25) = 200
x = 200/cos(25)
x = 220.675583792499 which is approximate.
x = 221
I'm rounding to the nearest whole number since every other value given to you is a whole number. Round as your teacher instructs.
This means the plane is roughly 221 km away from its starting point. In other words, side AC is about 221 km long.
Point CC is located at (4,3)(4,3) on the coordinate plane. Point CC is reflected over the xx-axis to create point C'C ′ . Point C'C ′ is then reflected over the yy-axis to create point C''C ′′ . What ordered pair describes the location of C''?C ′′ ?
Answer:
[tex]C" = (-4,-3)[/tex]
Step-by-step explanation:
Given
[tex]C = (4,3)[/tex]
Required
The coordinates of C"
From the question, we understand that:
C is reflected over x-axis to give C'
The rule to this is:
[tex]C(x,y) \to C'(x,-y)[/tex]
So, we have:
[tex]C(4,3) \to C'(4,-3)[/tex]
Next, C' is reflected over y-axis to give C''
The rule to this is:
[tex]C'(x,y) \to C"(-x,y)[/tex]
So, we have:
[tex]C'(4,-3) \to C"(-4,-3)[/tex]

If pi is rounded to a whole number, what is a reasonable estimate for the circumference of a circle with a diameter of 18 cm?
57 cm
50 cm
54 cm
56 cm
Answer:
54 cm
Step-by-step explanation:
Hi there!
1) Round pi
π = 3.14159265...
Rounded to a whole number ⇒ 3
2) Determine the circumference
C = πd where d is the diameter
Plug in the diameter
C = 18π
Plug in π
C = 18(3)
C = 54
Therefore, a reasonable estimate for the circumference of this circle would be 54 cm.

Cora invests $1000 at 5% compounded semi-annually. How long will it take, to the
nearest whole year, for her money to double? Use the formula A=P(1+r/n)^(nt),
where 0.05 and n=2 to find the answer.
It will take years for Cora's money to double when invested at 5%
compounded semi-annually
The solution is
Answer:
15 Years or 14.5 Years
Step-by-step explanation:
According to the Question,
Given That, Cora invests $1000 at Rate of 5% Per Annum. Interest is compounded semi-annually, After What time her money to get double.We Know, the formula A=P(1+r/n)^(nt) (where r=0.05 , p=1000 , A=2000 , n=2)Put the Given value in Formula, We get
2000 = 1000 (1 + 0.05/2) ^ 2t
2 = (1+0.025)^2t
2 = (1.025)^2t ⇔ 1.025^30 = 2.0975 ≈ 2
Thus, 2t = 30 ⇒ t = 15 Years
OR
2 = (1.025)^2t ⇔ 1.025^29 = 2.0464 ≈ 2
Thus, 2t = 29 ⇒ t = 14.5 Years

The triangles are similar to triangles AED are DCE is similar to AED, EBA is similar to AED, AFE is similar to AED, EFD is similar to AED.
We have to determineWhat triangles are similar to triangle AED?
According to the question
Alternate interior angles are formed when a transversal passes through two lines.
The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
In the triangle AED:
The angle is equal to 53.
Then,
A=180-90-53=37
DCE is similar to AED.
Here EBA, DCE, EF, D, and AFE bc it doesn’t matter about the size it matters about the angle whether it stays the same and you can clearly see that angle b, and f, angle, c, and angle e are all 90 degrees making the triangles I listed similar to triangle AED.
Hence, The triangles are similar to triangles AED are DCE is similar to AED, EBA is similar to AED, AFE is similar to AED, EFD is similar to AED.

Yk help me bru In the straight edge and compass construction of the angle bisector below which of the following reasons can be used to prove that angle DGB = angle EGB
Answer:
The correct Option is B
Step-by-step explanation:
Two Angles that are equal to the same angle must themselves be equal (Transitive property of equality)
BD = BE, because they are radii of the same circle. DG = EG because they are sides f equilateral triangle DEG. Therefore, the correct option is option A.
What is angle?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.
We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.
Angle can also refer to the size of such an angle or maybe a rotational angle. The length of such a circular arc divided by its radius is the traditional definition of this metric, which may also be signed. BD = BE, because they are radii of the same circle. DG = EG because they are sides f equilateral triangle DEG.
Therefore, the correct option is option A.

5 - 2x^2 = -15 solve the question using inverse operations
Answer:
x= √10 and x= -√10
Step-by-step explanation:
first look to isolate the term with the variable on one side
-5 +5 -2x² = -5 -15; subtract 5 from both sides(inverse of addition)
-2x² = -20; divide both sides by -2 (inverse of multiplication)
x² = 10; square root both sides (the inverse of raising to power of 2)
√x² =√10
x =±√10
