Answer:
a = 68°
Step-by-step explanation:
a and 112° are a linear pair and sum to 180° , that is
a + 112° = 180° ( subtract 112° from both sides )
a = 68°
if you were to construct a pareto chart (using the rule suggested in the book), how would the second bar in the graph be labeled?
When constructing a Pareto chart, the second bar would be labeled with the name of the item that has the second highest frequency or impact, as determined by the data being analyzed.
In a Pareto chart, the bars are typically labeled with the names of the items being analyzed, and the height of each bar represents the frequency or the impact of each item. The bars are typically ordered from largest to smallest, with the largest bar appearing on the left and the smallest bar on the right.
It is worth noting that the "rule" you referred to in the book might refer to the 80-20 rule, also known as the Pareto principle. This rule states that roughly 80% of the effects come from 20% of the causes. In the context of a Pareto chart, this means that you might expect the first few bars to represent a large portion of the total frequency or impact, while the later bars represent a much smaller portion.

in the given figure AB || CD PROVE THAT p+q+r = 180
The sum of angles p, q, and r is equal to 180 degrees.
A degree is a unit of measurement used in geometry to represent angles.
To prove this, we will use the concept of alternate interior angles. Alternate interior angles are angles that are formed on the inside of the two lines when they are parallel to each other. Since AB || CD, alternate interior angles p and q are equal.
We know that the sum of angles in a triangle is equal to 180 degrees. In this case, we have a triangle ABC with angles p, q, and r. Hence,
=> p + q + r = 180 degrees.
Next, since p and q are equal, we can represent them as p = q. Now, substituting the value of q into the above equation, we get:
=> p + p + r = 180 degrees.
This can be simplified to 2p + r = 180 degrees. But since p = q, we can replace p with q. Hence,
=> 2q + r = 180 degrees.
Finally, substituting the value of p = q into the above equation, we get:
=> 2p + r = 180 degrees.

A string with a linear density of 2 kg/m and a tension of 100 N is fixed at both ends. Determine the frequency of the first harmonic of the string.
Step-by-step explanation:
The frequency of the first harmonic of a string fixed at both ends can be determined using the formula:
f = (1 / 2L) * √(T / μ)
where f is the frequency, L is the length of the string, T is the tension, and μ is the linear mass density. Plugging in the given values:
f = (1 / 2 * L) * √(100 N / 2 kg/m)
= (1 / 2 * L) * √(50 N/m)
So, the frequency of the first harmonic depends on the length of the string, which is not specified in the problem.
Answer:
Step-by-step explanation:
The frequency of the first harmonic of a string fixed at both ends can be calculated using the formula:
f = (1 / 2L) * (T / μ)^(1/2)
where:
f = frequency
L = length of the string
T = tension
μ = linear density of the string
Plugging in the values:
f = (1 / 2 * L) * (100 N / 2 kg/m)^(1/2)
f = (1 / 2L) * (10 N/kg)^(1/2)
We don't have the length of the string, L, so we can't calculate the frequency.
What is the longest line segment that can be drawn in a right rectangular prism that is 14 cm long, 13 cm wide, and 9 cm tall?
The longest line segment that can be drawn in a right rectangular prism is 21.1 cm.
Let us assume the right rectangular prism be labelled as shown in figure. Now the longest possible line here is the diagonal between two most far points like A and G. So, finding the length of AG from triangle AGC.
But, prior to this calculation, we need to find AC. It will be calculated from the traingle ABC.
So, AC² = AB² + BC²
AC² = 14² + 13²
AC² = 196 + 169
AC² = 365
AC = 19.1 cm
Now, finding length of AG.
AG² = AC² + GC²
AG² = 365 + 9²
AG² = 365 + 81
AG² = 446 cm
AG = ✓446
AG = 21.1 cm
Thus, the diagonal AG is 21.1 cm.

Find the area of the circle shown.
Use 3.14 as an approximation of pi.Round your answer to the nearest tenth
Answer: A = 19.6^2 ( 19.6 to the 2nd power )
Step-by-step explanation:
Area of a circle = 3.14 * r^2
A = 3.14 * 2.5^2
A = 19.625
19.625 rounded to the nearest tenth is 19.6
According to the information we can infer that the area of the circle with a radius of 2.5 is approximately 19.63 square units.
How to calculate the area of the circle?The area of a circle is given by the formula A = πr², where A represents the area and r represents the radius.
In this case, the radius is given as 2.5 units. Substituting this value into the formula, we have:
A = π(2.5)²A = π(6.25)Using an approximate value of π as 3.14159, we can calculate the area:
A ≈ 3.14159 × 6.25A ≈ 19.63So we can conclude that the area of the circle with a radius of 2.5 units is approximately 19.63 square units.

(i) Are there values of k such that the curve y = (k + 3)x² - 3x lies completely above the line y = x + k? Justify your answer. (ii) Explain the relationship between the curve and the line in part (i).
Answer:
(i) No
(ii) The line and curve always intersect in two places
Step-by-step explanation:
You want to know if there are values of k such that the curve y = (k+3)x²-3x lies completely above the line y = x+k. And you want to know the relationship between the line and the curve.
(i) DiscriminantThe number of points of intersection between the line and the curve can be found by considering the discriminant of the quadratic equation for the difference of the y-values.
The line and curve will intersect when their y-values are equal:
(k +3)x² -3x = x +k
(k +3)x² -4x -k = 0 . . . . . compare to ax²+bx+c=0
The discriminant is the value of b²-4ac, so is ...
d = (-4)² -4(k+3)(-k) = 16 +4k(k -3)
Writing this in vertex form, we have ...
4(k² -3k) +16 = d
4(k² -3k +2.25) +16 -4(2.25) = d . . . . . "complete the square"
4(k -1.5)² +7 = d
The square is always positive, and it is added to a positive value (7), so the discriminant d is always positive. This means there are always two points of intersection between the curve and the line.
(ii) RelationshipAs we saw above, the line and curve will always intersect at two points. This means there are always parts of the curve both above and below the line.
__
Additional comment
For the value k=-3, the "curve" becomes a line with slope -3 through the origin. It will intersect the line y=x-3 at one point. It seems reasonable to exclude that case from consideration.

This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.
Given the height of the plane = 5925 feet
let the distance between A to B be x and distance from B to the position of the plane is y as shown in the image,
angle of elevation from point A = 16°
the angle of elevation from point B = 31°
using trigonometric functions,
tanα = perpendicular/base
base = x + y
perpendicular = 5925 feet
tan(16) = 5925/(x + y)
x + y = 5925/tan(16)
y = 5925/tan(16) - x.........(1)
and tan(32) = 5925/y
y = 5925/tan(32)
substitute the value of y from equation 1
5925/tan(16) - x = 5925/tan(32)
5925/tan(16) - 5925/tan(32) = x

What is the law of sines?The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔPQR
Now , the measure of ∠PQR = 90°
The measure of side PR = 13 cm
The measure of side PQ = 5 cm
The measure of side QR = 12 cm

(-6)² + 3(-6) - 4 > 0
36 - 18 - 4 > 0
36 - 22 > 0
14 > 0
True.
x² + 3x - 4 > 0
(-2)² + 3 x (-2) - 4 > 0
4 - 6 - 4 > 0
-6 > 0
This is not true.
x² + 3x - 4 > 0
0 + 3 x 0 - 4 > 0
0 + 0 - 4 > 0
-4 > 0
This is not true.
x² + 3x - 4 > 0
5² + 3 x 5 - 4 > 0
25 + 15 - 4 > 0
40 - 4 > 0
36 > 0
This is true.
Thus,
