Unit 8: Right Triangles & Trigonometry Homework 4: Trigonometry: Ratios & Finding Missing Sides
Answers
Answer:
26.69
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached
The missing side is x;
From the triangle we are given;
Opposite = x
Hypotenuse = 29
Angle of elevation = 67 degrees
Using the SOH CAH TOA identity;
Sin theta = opposite/hypotenuse;
sin 67 = x/29
x = 29sin67
x = 29(0.9205)
x = 26.69
Hence the length of the missing side is 26.69
All trigonometric ratios of triangle PQR were calculated.
In the given right triangle PQR
PR = 14
QR = 50
So, using Pythagoras' theorem
PQ = 48
What are Sine, Cosine, and Tangent of a triangle?Sine of an angle = Opposite side / Hypotenuse
cosine of an angle = Adjacent side/ Hypotenuse
Tangent of an angle = Opposite side/ Adjacent side
So, SinQ = 14/50 =7/25
CosecQ = 1/SinQ = 25/7
CosQ= 48/50 = 24/25
SecQ = 1/CosQ = 25/24
TanQ = 14/48 = 7/24
CotQ = 1/tanQ = 24/7
SinR=24/25
CosecR = 1/SinR= 25/24
CosR=7/25
SecR = 1/Cosr = 25/7
TanR =24/7
CotR = 1/tanR = 7/24
Thus, All trigonometric ratios of triangle PQR were calculated.

A) The graph opens up and the vertex is a maximum.
B) The graph opens up and the vertex is a minimum.
C) The graph opens down and the vertex is a maximum.
D) The graph opens down and the vertex is a minimum.
Answers
Answer:
C) The graph opens down and the vertex is a maximum.
Step-by-step explanation:
Just took the quiz on K12, good luck! :)
Option (C) will be the correct option.
Properties of a quadratic equation: If a quadratic function has been given as,
f(x) = ax² + bx + c
Vertex of the parabola is represented by [tex][-\frac{b}{2a}, f(\frac{b}{2a})][/tex]
And the sign of the leading coefficient decides the opening of the
parabola.
For positive sign of 'a' → Parabola will open upwards
For negative sign of 'a' → Parabola opens downwards
Quadratic function given in the question is,
f(x) = -4x²+ 6x - 7
Leading coefficient → (-4)
Negative sign represents the opening of the parabola downwards.
And the vertex will be a maximum.
Therefore, Option (C) will be the correct option.

The graph that correctly represents the linear piece-wise function is the first graph.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.A cab company charges a $5 pick up fee and $1 for each mile up to 10 miles, hence:
[tex]y = 5 + x, x \leq 10[/tex]
Hence, at x = 10, we have that:
y = 5 + 10 = 15.
$2 per mile for each mile over $10, hence:
[tex]y = 15 + 2(x - 10), x \geq 10[/tex]
Hence, at x = 14, we have that:
y = 15 + 2(14 - 10) = 15 + 8 = 23.
Thus the first graph is correct.

Answers
Corresponding point on a unit circle is equal to [tex]\boldsymbol{\left [ \frac{-\sqrt{3}}{2},\frac{-1}{2} \right ]}[/tex]
So, option C. is correct.
Define unit circle.A unit circle is a circle with radius is equal to one.
Any point on a unit circle is of the form [tex]\boldsymbol{\left ( cos\, \theta, \sin\, \theta \right )}[/tex]
Value of [tex]\theta[/tex] is [tex]\boldsymbol{\frac{7\pi}{6}}[/tex]
So, corresponding point on a unit circle is equal to [tex]\boldsymbol{\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]}[/tex]
[tex]\left [\cos \left (\frac{7\pi}{6} \right ),\sin \left (\frac{7\pi}{6} \right ) \right ]=\left [\cos \left (\pi + \frac{\pi}{6} \right ),\sin \left (\pi + \frac{\pi}{6} \right ) \right ][/tex]
[tex]=\left [ -cos\left ( \frac{\pi}{6} \right ),-\sin\left ( \frac{\pi}{6} \right ) \right ]\\=\boldsymbol{\left [ \frac{-\sqrt{3}}{2},\frac{-1}{2} \right ]}[/tex]

Two 6-sided dice are rolled. What is the probability that the sum is odd and the number on one of the dice is a 5?
Answers
Answer:
The odds are 12
Step-by-step explanation:
The odds of rolling an odd number from the sum of two rolls requires that we roll one even number from one die and an odd number from another die.
Thus the probability of the event is P(e) = 1/12.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
For the given situation,
The sample space for rolling two 6 sided dice is
[tex]s[/tex] = { [tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]
[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]
[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]
[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]
[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]
[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]}
So, [tex]n(s)=36[/tex]
Let the event be the probability that the sum is odd and the number on one of the dice is a 5
Consider that the probability that the sum is odd be a,
[tex]a =[/tex] { [tex](1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(3,6),\\[/tex]
[tex](4,1),(4,3),(4,5),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5) }[/tex] }
Consider that the probability that the number on one of the dice is 5 be b,
[tex]b=[/tex] { [tex](1,5),(2,5),(3,5),(4,5),(5,5),(6,5)[/tex] }
The probability of the event can be find by taking intersection of a and b
⇒[tex]e=a[/tex]∩[tex]b[/tex] = { [tex](2,5),(4,5),(6,5)[/tex] }
⇒[tex]n(e)[/tex] [tex]=3[/tex]
Probability (event )=[tex]\frac{n(e)}{n(s)}[/tex]
⇒[tex]p(e)=\frac{3}{36}[/tex]
⇒[tex]p(e)=\frac{1}{12}[/tex]
Hence we can conclude that the probability of the event is P(e) = 1/12
