Answer:
[tex]\displaystyle \frac{199}{18}[/tex]
Step-by-step explanation:
Fraction Operations
Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.
[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]
[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]
Now for the sum of the last two fractions:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]
Make both denominators equal by multiplying by 2 both parts of the first fraction:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]
[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]
Now multiply by 7/9:
[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]
4.) solve for f(g(2))
Answer:
[tex]f(g(2))=10[/tex]
Step-by-step explanation:
We have the two functions: [tex]f(x)=3x-5[/tex] and [tex]g(x)=2+\frac{6}{x}[/tex].
We want to find [tex]f(g(2))[/tex].
So, let's use the second function to find [tex]g(2)[/tex] first:
[tex]g(2)=2+\frac{6}{2}[/tex]
Divide:
[tex]g(2)=2+3[/tex]
Add:
[tex]g(2)=5[/tex]
Therefore, our expression is the same to [tex]f(g(2))=f(5)[/tex].
Now, we can substitute 5 for f(x). This yields:
[tex]f(5)=3(5)-5[/tex]
Multiply:
[tex]f(5)=15-5[/tex]
Subtract:
[tex]f(5)=10[/tex]
So:
[tex]f(g(2))=10[/tex]
And we're done!

Simpson's Paradox
Step-by-step explanation:
given the regular polygon, select all of the rotations and reflections that carry the figure onto itself.
Answer:
A. A rotation of 72º around the center, point D.
C. A reflection across line b through one vertex, the center d.
E. A reflection across line c, and the midpoint of the opposite side
Step-by-step explanation:
From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:
[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)
Where:
[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.
[tex]n[/tex] - Number of sides, measured in centimeters.
If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:
[tex]\theta = \frac{360^{\circ}}{5}[/tex]
[tex]\theta = 72^{\circ}[/tex]
In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)
By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)

The population in a certain town is increasing linearly each year. The population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990
Answer:
1999
Step-by-step explanation:
The equation which represents the given situation is P=180t+620.
Given that, the population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, the standard form of the population is increasing linearly is P = mt + b.
Where m is the slope = (y2-y1)/(x2-x1)=(1520-1160)/(5-3)
=360/2
=180
So, 1160=180 × 3 + b
⇒ 1160=540 × 3 + b
⇒ b=620
Then, the equation is P=180t+620
Therefore, the equation which represents the given situation is P(t)=180t+620.

Measures of two anges 48 degrees are shown in a triangle. Write a equation showing the value of X
Answer:84
Step-by-step explanation:
Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x
Answer
48+48+x=180 x=84
Step-by-step explanation:
The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.
In short, this means that all three angles have to equal up to 180 degrees
48+48=96
180-96=84 x=84
To check your answer add
48+48+84 should equal 180. It does

3. Jade is checking one of her zeros to a quadratic function. Her steps are shown. What must be true of this value?
Check = 2
0= (2)2 – 2(2) – 3
0= 4 - 4 - 3
0 -3
Answer:
Option C: since a false statement resulted, it means x = 2 is not a zero.
Step-by-step explanation:
We are told that She is checking the zeros of her quadratic function.
Now the zeros of a quadratic function f(x) are values of that make f(x) = 0. In order words they are basically the roots of the function or the x-intercept.
Now, she has tried x = 2 into her quadratic equation and it didn't yield zero.
Since it yielded -3 and not 0, it means 2 is not a zero of the quadratic function.

The perimeter of an equilateral triangle is 96 inches. If the length of each side is (2x + 6), find the value of x.
An equilateral triangle has three equal sides. Let's try to first find the actual value of each side of the triangle!
1. Let's first find the length of each side of the triangle in inches based on the information we know!96 inches is the perimeter of the triangle. The triangle has three equal sides. We can find the length of each side by dividing 96 inches by 3!
96 / 3 = 31 inches
The length of each side in the equilateral triangle is 31 inches.
2. Now, let's find x using the information we know!We know that the length of each side is 2x + 6, and we previously found that the length of each side in the equilateral triangle is 31 inches. We are trying to find x, so we can create an equation and isolate x!
31 = 2x + 6
-6 -6
25 = 2x
÷2 ÷2
12.5 = x
Yay, we just found x! That's the answer! Feel free to ask any questions if you need help. I'm not here to judge; I'm here to help. :)
