Answer:
Yeah true
Step-by-step explanation:
Because it makes sense
It is true that when developing a proof, focusing on the "given" information is crucial as it forms the foundation of the logical argument leading to the conclusion that needs to be proven.
When developing a plan for a proof, it is indeed important to look at the "given" information. This is true because in the context of mathematical proofs, the "given" information represents the starting point from which you will build you argument to reach a conclusion. These are the facts, definitions, or previously proven theorems that can be used in establishing the validity of the statement you are tasked to prove.
To develop a successful proof, one generally follows a systematic approach:
Identify the given information in the problem.Analyze what the problem is asking you to find or prove.Consider what principles, theorems, or rules apply based on the given information.Develop a logical sequence of steps that connects the given information to the conclusion you are trying to reach.This structured approach to problem-solving involves using what you know to logically arrive at a conclusion that was previously unknown or needs to be proven. This method not only applies to mathematics but also to other fields that require logical reasoning and evidence-based conclusions.

The sequence given is a geometric sequence with a common ratio of -3. The sum of the first ten terms of the sequence is calculated using the formula for the sum of a geometric series to be -236196.
Explanation:The sequence given, 4, -12, 36, -144, ..., is actually a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this sequence, the common ratio is -3.
To find the sum of the first n terms in a geometric sequence, we use the formula: S_n = a(1 - r^n) / (1 - r), where S_n is the sum of the first n terms, a is the first term in the sequence, r is the common ratio, and n is the number of terms.
If we insert our values into formula, we get: S_10 = 4*(1 - (-3)^10) / (1 - (-3)), which results in S_10 = -236196.
So, the sum of the first ten terms of the sequence is -236196.

Please help somehow with graphing, I'm very very confused!
Ok, so first, the y-intercept is always the last number. So the y-intercept for the first equation would be -1, and for the second equation, 4.
Put a dot, or a point on -1and 4 on the graph.
The slope is always he number with an x.
So the slope would be 3 for the first equation.
And the slope for the 2nd equation would be -2.
If the slope doesn't have a denominator, put 1 as it's denominator.
So, 3x would turn into
[tex] \frac{3x}{1} [/tex]
And -2x would turn into
[tex] \frac{ - 2x}{1} [/tex]
So the rule for slope is:
[tex] \frac{rise}{run} [/tex]
So, go to your -1, and go up 3 and 1 right. Keep doing that until you reach the end of the graph.
Now, go to your -4, go down 2 and go left 1. Keep doing that until you reach the end of the graph.
Now, draw the lines.
I'll show on piece of paper how to do this if you dont get the explanation I gave.

shade in circles and write equivalent fractions 3/6
Answer:
A fraction that would be equivalent to 3/6 would be 1/2, therefore a shaded circle would be half of a circle.

Divide the circle to six congruent pieces. Shade three pieces.
Equivelent fractions:

The function f(x)=x^2 and its transformation f(x)=(x-k)^2 are shown below. What is the value of k?
Answer:
f(x - k) = (x - k)²⇒ k = 5Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
==============================================
Look at the picture.
The graph has been shifted 5 units to the right.
Therefore we have f(x - 5).

What is the slope of the line l described by the equation below? y=-2x+4
Answer:
The slope of the line would be -2.
Step-by-step explanation:
Because the equation is a line, the slope is the same throughout the entire graph on the equation.
Lets let f(x)=y=-2x+4.
f(0) = -2(0) + 4 = 4
f(0)=4
f(1) = -2(1) + 4 = 2
f(1)=2
Use the equation to find slope.
m(slope) = [tex]\frac{2-4}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = -2
The slope would be -2.
Or:
Use the equation y = mx + b where m=slope.
In the equation y=-2x+4, m=-2.
The slope is -2.
Answer:
y = -2x + 4 slope is -2

What is the secant of the circle?A secant is a line that intersects a circle in exactly two pints. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one half the positive difference of the measure of the intercepted arcs.
According to the given question.
WSX is a secant angle.
TR and WX are intercepted arcs.
Therefore, by the secant of the circle formula
[tex]\frac{1}{2} (116^{o} -WX) = 45^{o}[/tex]
[tex]\implies 116^{o} -WX = 90^{o}[/tex]
[tex]\implies WX = 116^{o} -90^{o}\\ \implies WX = 26^{o}[/tex]
Hence, the measure of the arc WX is 26 degrees.
Thus, option B is correct.

Answer:
D
Step-by-step explanation:
The opposite angles of the inscribed quadrilateral are supplementary
∠A + ∠C = 180 and ∠B + ∠D = 180
∠B + ∠D = 93 + x + 30 = x + 123, hence
x + 123 = 180 ( subtract 123 from both sides )

About ______% of the area is between zequalsminus1 and zequals1 (or within 1 standard deviation of the mean).
According to the empirical rule, about 68% of the data in a normal distribution is within one standard deviation of the mean, which corresponds to z-scores between -1 and 1.
Explanation:The question is about the percentage of data found within certain ranges of standard deviations from the mean in a normal distribution, as represented by z-scores. Specifically, it refers to the proportion of data within one standard deviation (z-scores between -1 and 1). According to the empirical rule (also known as the 68-95-99.7 rule), about 68% of the data in a normal distribution is within one standard deviation of the mean.
So, about 68% of the area is between z=-1 and z=1 (or within 1 standard deviation of the mean). This empirical rule is a quick way to estimate the spread of data in a normal distribution and is useful for various statistical analyses.

What are the roots of the polynomial equation x^3 - 7 x = 6x - 12
Answer:
x(roots) = 3, 1, -4.
Step-by-step explanation:
Find the roots by solving for x.
Hope this helps,
Davinia.
x^3 - 7x = 6x -12
Subtract 6x from both sides:
x^3 - 13x = -12
Add 12 to both sides:
x^3 - 13x +12 = 0
Factor the left side:
(x-3) (x-1)(x+4) = 0
Now solve for x in each set of parenthesis so they all equal 0:
x = 3
x = 1
x = -4
The roots are 3,1, -4

154hr 36 mins after Thursday 1:26pm?
The time and day that will be 154 hours and 36 minutes after Thursday 1:26pm is Thursday at 8:02pm.
Explanation:To determine the day and time that will be 154 hours and 36 minutes after Thursday 1:26pm, we need to perform some calculations:
Add 154 hours to the given time of 1:26pm. This gives us a new time of 7:26pm on the same day.Next, add 36 minutes to the new time of 7:26pm. This gives us a final time of 8:02pm on the same day.Since the question asks for the day as well, the answer would be the same Thursday, with a time of 8:02pm.Therefore, it will be Thursday at 8:02pm 154 hours and 36 minutes after Thursday 1:26pm.

Step-by-step explanation:
[tex]f(x)=\dfrac{x+2}{2}\\\\f(-8)\to\text{put x = -8 to the equation of the function}\ f:\\\\f(-8)=\dfrac{-8+2}{2}=\dfrac{-6}{2}=-3[/tex]
The value of f(-8) refers to the result of a function, f(x), when x equals -8. However, without the specific function, we cannot provide an exact value.
Explanation:To determine the value of f(-8), we need to know the function f(x). In mathematics, f(-8) typically refers to the value of a function, denoted as f(x), at x=-8. For instance, if we have the function f(x) = x^2, then f(-8) would equal to (-8)^2, which is 64. However, without knowing the specific equation for f(x), we cannot provide the exact answer for f(-8).
