Answer:
[tex]160^\circ[/tex] is the degrees value of [tex]\theta = \dfrac{8 \pi}{9}[/tex].
Step-by-step explanation:
We are given the following details about the angle [tex]\theta[/tex]:
[tex]\theta =\dfrac{8\pi}{9}\text{ radians}[/tex]
It is know that the relation between radians and degree units is as follows:
[tex]\pi \text{ radians} = 180 ^\circ[/tex]
We can use simply use unitary method to convert radian value of [tex]\theta[/tex] to degrees.
[tex]\pi \text{ radians} = 180 ^\circ[/tex]
[tex]\Rightarrow 1 \text { radian}= \dfrac{\pi}{180} ^\circ[/tex]
[tex]\Rightarrow \dfrac{8\pi}{9} \text{ radians} = \dfrac{180}{\pi} \times \dfrac{8\pi}{9} ^\circ\\\Rightarrow \dfrac{180 \times 8}{9}^\circ\\\Rightarrow 20 \times 8^\circ\\\Rightarrow 160 ^\circ[/tex]
Hence, [tex]\theta = 160^\circ[/tex]

3) The sum and the difference of the LCM and GCD of two numbers are 312 and 264 respectively. Find the numbers if their sum is 168.
Answer:
The numbers are 72 and 96.
Step-by-step explanation:
LCM + GCF = 312
LCM - GCF = 264
2*LCM = 576
LCM = 576/2 = 288
HCF = 312–288 = 24
The product of two numbers = HCF*LCM
Let the numbers be x and (168-x)
x(168-x) = 24*288 = 6912
x^2–168x+6912 = 0
x = [168 +(168^2 -4*6912)^0.5]/2
= [168 +(28224–27648)^0.5]/2
= [168 + 576^0.5]/2
= (168+24}/2
= 192/2
= 96 and the other number is 168–96 = 72.

Answer:
THE FUNCTION IS ALWAYS INCREASING.
Complete question: The graph of f(x)= power of 3√x + 8 is shown.
Step-by-step explanation:
See attachment for the missing graph.
when x = -16 ; y = -2
when x = -12 ; y = -1.5
when x = -8 ; y = 0
when x = -6 ; y = 1.25
when x = 0 ; y = 2
when x = 6 ; y = 2.5
As the value of x increases, so does the value of y. Thus, the function is always increasing.

Answer:
S = {1H,2H,3H,4H,5H,6H,1T,2T,3T,4T,5T,6T}
Step-by-step explanation:
A sample space is the set of all outcomes that may come. It consists of all the values that may result in result of an experiment.
In the given problem, we have to find the sample space of rolling a dice and flipping a coin
As the dice has 6 sides and coin has 2 sides
The number of outcomes are: 6*2 = 12
The outcome of dice can either be with heads of coin or tails of coin.
The sample space will be:
S = {1H,2H,3H,4H,5H,6H,1T,2T,3T,4T,5T,6T}

Step-by-step explanation:
It appears that all choices have the 1st part the same, so we are looking at domains. I recommend drawing the functions without the domain limitations. We know that the linear function is closed so it's inequality is either [tex]\geq[/tex] or [tex]\leq[/tex]. So eliminate B and D. Since the quadratic function continues to the left the inequality sign should be <. So the answer is C
find points of discontinuity y=x-8/x^2+6x-7
Answer:
Step-by-step explanation:
You'll need to use parentheses here to remove ambiguity regarding what's in your denominators:
x - 8 x - 8
y = ------------------ = -----------------
x^2 + 6x - 7 (x + 7)(x - 1)
This last result becomes undefined at x = -7 and x = 1, and thus its graph is discontinuous at those x- values.
The points of discontinuity is x = -7, x = 1
Use parentheses to remove ambiguity considering the denominators
[tex]y=x-8/x^{2} +6x-7[/tex]
= x-8 ÷ (x+7)(x-1)
The result becomes undefined at x = -7
and x = 1,
thus its graph is discontinuous at those x values.
Therefore the points of discontinuity is x =-7 and x = 1.

What is the volume of the following triangular prism?
5 cm
15 cm
4 cm
cubic centimeters. You must submit your neat and organized work once you have submitted the test.
Write only the number.
10 points need fast
Answer:
[tex]V=150cm^3[/tex]
Step-by-step explanation:
First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.
The area of the triangle is given by the formula:
[tex]A_T=\frac{bh}{2}[/tex]
where b is the base: [tex]b=4cm[/tex] and h is the height: [tex]h=5cm[/tex]
thus, in this case we have:
[tex]A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2[/tex]
And now, the volume will be the area of the triangle multiplied by the length [tex]l=15cm[/tex] of the prism:
[tex]V=A_T*l[/tex]
Substituting the known values:
[tex]V=10cm^2*15cm\\V=150cm^3[/tex]
The volume in cubic centimeters is 150.

A spinner has four equal sections, with one letter from the word "MATH" in each section.
Type your response in each blank below.
1. You spin the spinner 20 times. About how many times do you expect it will land on A?
2. You spin the spinner 80 times. About how many times do you expect it will land on something other than A?
Explain your reasoning.
Answer:
1. 5 times
2. 60 times
Step-by-step explanation:
there is only one a so its 1/4 times 20 and 4 because that is the total
20/4= 5
there is 3 because there is letters that are not a
3/4 times 80
240/4
1. The number of times expected that should be landed on A should be 5 times.
2. The number of times expected should be 60 times.
Calculation of the number of times:1. Since A spinner has four equal sections, with one letter from the word "MATH" in each section.
So, here the number of times should be
= [tex]20\div 4[/tex]
= 5
2. The number of times should be
[tex]= 3/4 \times 80\\\\= 240\div 4[/tex]
= 60

what is the sum of the interior angles of a polygon shown below?
Answer: The sum of the interior angles of a polygon shown in the picture is [tex]540^{\circ}[/tex].
Step-by-step explanation:
The given polygon is a regular pentagon having 5 sides.
The sum of the interior angles of a regular polygon is given by :-
[tex](n-2)\times180^{\circ}[/tex], wherer n= number of sides of the regular polygon.
Since it has 5 sides, then the sum of the interior angles of a polygon would be
[tex](5-2)\times180^{\circ}\\\\=3\times180^{\circ}\\\\=540^{\circ}[/tex]
Hence, the sum of the interior angles of a polygon shown in the picture is [tex]540^{\circ}[/tex].

The height of a parallelogram is three times its base. If the area of the parallelogram is 675 square inches, find its base and height.
Which of these choices are correct?
b = 25 in & h = 75 in
b = 75 in & h = 225 in
b = 45 in & h = 135 in
b = 25 in & h = 12.5 in
Answer:
Step-by-step explanation:
let base be x and height be 3x
we know area of parallelogram is
base*height
ie x*3x=675
3x^2=675
x^2=675/3
x^2=225
x= square root of 225
x=15
therefore base =15
height = 45
