Answers:
x = 108
y = 111/5 = 22.2
========================================================
Explanation:
The angles 72 and x form a 180 degree straight line.
72+x = 180
x = 180-72
x = 108
Angles x and 5y-3 are congruent corresponding angles assuming the lines pointing to the northwest are parallel
5y - 3 = x
5y - 3 = 108
5y = 108+3
5y = 111
y = 111/5
y = 22.2
Answer:
x = 108°
y = 22.2°
Step-by-step explanation:
Angles on a straight line sum to 180°.
[tex]\implies 72^{\circ} + x = 180^{\circ}[/tex]
[tex]\implies 72^{\circ} + x - 72^{\circ} = 180^{\circ} - 72^{\circ}[/tex]
[tex]\implies x = 108^{\circ}[/tex]
Corresponding Angles Theorem
When a straight line intersects two parallel straight lines, the angles in the same relative position are congruent.
Assuming the two lines that appear parallel in the given diagram are parallel:
[tex]\implies (5y - 3)^{\circ} = x^{\circ}[/tex]
[tex]\implies 5y - 3 = 108[/tex]
[tex]\implies 5y - 3 + 3 = 108 + 3[/tex]
[tex]\implies 5y = 111[/tex]
[tex]\implies 5y \div 5 = 111 \div 5[/tex]
[tex]\implies y = 22.2^{\circ}[/tex]

Vertical Asymptote = 4
Horizontal Asymptote = 0
X - intercept = No x - intercepts
Y - intercept = 1/4
Domain:
The the domain of a function referred as the set of inputs accepted by the function
Given,
The function is,
[tex]f(x)=\frac{x-2}{x^2+2x-8}[/tex]
Here we need to find the domain, vertical asymptote, horizontal asymptote, x - intercept, and y-intercept.
To find the domain and intercepts, we have to plot the graph for the given function.
So, the graph of the function is attached below. It can be drawn using the graphing calculator.
As per the graph,
Domain = [tex]\left(-\infty, -4\right) \cup \left(-4, 2\right) \cup \left(2, \infty\right)[/tex]
And the values of
x - intercept = No x-intercepts
y - intercept = 1/4
Now, the vertical asymptote is calculated as,
The line x=L is a vertical asymptote of the function f(x), if the limit of the function (one-sided) at this point is infinite.
In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.
So, find the points where the denominator equals 0 and check them.
x = -4
Then,
[tex]\lim_{x \to -4^+} \frac{1}{x + 4}=\infty[/tex]
Since the limit is infinite, then x=−4 is a vertical asymptote.
And the horizontal asymptote is,
Line y=L is a horizontal asymptote of the function y=f(x), if either '
[tex]\lim_{x \to \infty} f{\left(x \right)}=L[/tex] or [tex]\lim_{x \to -\infty} f{\left(x \right)}=L[/tex] and L is finite.
When we calculate the limits:
[tex]\lim_{x \to \infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0\\\\\lim_{x \to -\infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0[/tex]
Thus, the horizontal asymptote is y=0.

(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bucket of popcorn and the other axis to represent the number of drinks.
(b) Explain your graph.
Answer: Do you know the answer to this yet??
Step-by-step explanation:
The equation is 4x + 2y = 45 and The y-intercept is the point (0,22.5) and The x-intercept is the point (11.25, 0)
Given,
Kevin took $45 with him to spend on snack
and, The price for each bucket of popcorn was $4.
To plot the graph
Now, According to the question:
Sketch the graph that represents the situation and label the intercepts
Let,
x ------> the number of bags of popcorn
y -----> the number of drinks.
we know that
The price for each bag of popcorn was $4
The price of each drink was half the price of a bag of popcorn
So, The price of each drink was (1/2)$4 = $2
The total bags of popcorn multiplied by $4 plus the number of drinks multiplied by $2 must be equal $45
The equation that represent this situation is :
4x + 2y = 45 -----(1)
Now, Find the y - intercept form:
The y-intercept is the value of y when the value of x is equal to zero
For, x = 0 put the value of x in equation(1)
4(0) + 2y = 45
2y = 45
y = 22.5
The y-intercept is the point (0,22.5)
That means -----> The number of drinks that Kevin can buy when the number of bags of popcorn is equal to zero
For, y = 0 put the value of x in equation(1)
4x + 2(0) = 45
4x = 45
x = 11.25
The x-intercept is the point (11.25, 0)
That means -----> The number of drinks that Kevin can buy when the number of bags of popcorn is equal to zero
Hence, The equation is 4x + 2y = 45 and The y-intercept is the point (0,22.5) and The x-intercept is the point (11.25, 0)

As a result, after demonstrating that P(k) is true for any chosen value of k, we also demonstrated that P(k + 1) is true. According to the induction hypothesis, P(n) is true for all n ∈ Z+
What is mathematical induction ?To demonstrate that the mathematical proposition P(n) holds for all natural integers n = 1, 2, 3, 4,..., one uses the mathematical induction technique. It is frequently referred to as the induction principle in mathematics. We establish that P(1) holds in order to demonstrate a result P(n) using the mathematical induction technique. If P(1) is valid, we can assume that P(k) holds for some natural number k and use this assumption to demonstrate that P(k+1) is valid. The assertion P(n) applies to all natural numbers if and only if P(k+1) holds true.
Let
P(n): 1×2 + 2×3+3×4+........+n(n+1)=[tex]\frac{n(n+1)(n+2)}{3}[/tex]
Putting n =1 we get
P(1):1×2 =2
and
[tex]\frac{1(1+1)(1+2)}{3}=\frac{1(2)(3)}{3} =2[/tex]
Therefore P(1) is true.
Let P(K) is true
So,
P(k): 1×2 + 2×3+3×4+........+k(k+1)=[tex]\frac{k(k+1)(k+2)}{3}[/tex]
Now we have to show that P(k +1 )is also true.
P(k+1): 1×2 + 2×3+3×4+........+k(k+1)+(k+1)(k+2)=[tex]\frac{k(k+1)(k+2)}{3}+ (k+1)(k+2)[/tex]
= (k+1)(k+2)[[tex]\frac{k}{3}+1[/tex]]
=[tex]\frac{(k+1)(k+2)(k+3)}{3}[/tex]
P(k + 1) follows, and it is likewise true.
As a result, after demonstrating that P(k) is true for any chosen value of k, we also demonstrated that P(k + 1) is true. According to the induction hypothesis, P(n) is true for all n ∈ Z+.
