Step-by-step explanation:
Supplementary angles are angles that have the sum of their angles to be 180°. Hence if <1 and <2 are supplements, then <1+<2 = 180°.... 1
Similarly if <3 and <4 are supplements, then <3+<4 = 180° ....... 2
Equating the left hand side of both equations since they are both equal to 180°, we will have;
<1+<2 = <3+<4 ....... 3
From the question we are told that <1 = <4, substituting this condition into equation 3;
From 3; <1+<2 = <3+<4
<4+<2 = <3+<4 (since <1 = <4)
subtract <4 from both sides
<4+<2 -<4= <3+<4 -<4
<2 = <3 (Proved!)

What is the interest earned on an invest of $590 at a simple interest rate of 12.8% over 3 years
Answer:
$ 226.56
Step-by-step explanation:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 12.8%/100 = 0.128 per year,
then, solving our equation
I = 590 × 0.128 × 3 = 226.56
I = $ 226.56
The simple interest accumulated
on a principal of $ 590.00
at a rate of 12.8% per year
for 3 years is $ 226.56.
590 · 12.8% = 590 · .128 = 75.52
75.52 · 3 = 226.56

What is
Mean
Medium
And Mode
Answer:
mean is the average value in the list.
first you add all number, then divide that value by the total number in the list
lets say (2,3,4,5)
you add 2+3+4+5 = 15 / 4
4 is the count
you'll get the average.
medium is the middle value in the list, but you should list from least to greatest
mode is repeated value in the list
Answer:
Step-by-step explanation:
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers.
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory.
The mode is the value that appears most often in a set of data. The mode of a discrete probability distribution is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
Translate the following phrase into an algebraic expression. use the variable n to represent the number. 4 less than triple a number
Work Shown:
n = a number, aka a placeholder for a number
3n = triple a number
3n-4 = four less than triple a number
So whatever n is, we multiply by 3 and then subtract off 4.
As an example, if n = 12, then 3n-4 = 3*12-4 = 36-4 = 32.

Sam is estimating 74.5 x 3.6 by rounding to 1sf. Which one of these calculations can she use??
Answer:
70 x 4
Step-by-step explanation:
To round to one significant figure we have to round each numbers to the first numbers greater than 0
To round 74.5 to 1sf we have to round it to the nearest 10. As the number next to it (4) is less than 5 we will round down to 70
To round 3.6 to 1sf we have to round to the nearest whole number. As the number next to it (6) is greater than 5 we will round up to 4

A particle is moving along a coordinate axis such that its position is defined as s(t) = t3 − 5t2 − 8t where t ≥ 0. When is the particle speeding up?
The particle is speeding up after 1.67 seconds.
What is displacement ?
In physics, displacement refers to the distance and direction of an object's change in position from its starting point to its ending point. It is a vector quantity, which means that it has both magnitude and direction.
Displacement is different from distance, which is the total length of the path an object has traveled, regardless of direction. Displacement only considers the straight-line distance and direction between the starting and ending points.
According to given conditions :
To determine when the particle is speeding up, we need to find the acceleration of the particle.
The acceleration of the particle is given by the second derivative of its position function:
a(t) = s''(t) = 6t - 10
The particle is speeding up when its acceleration is positive. So, we need to find the values of t for which a(t) > 0.
Setting a(t) > 0, we have:
6t - 10 > 0
6t > 10
t > 10/6
t > 1.67
Since t ≥ 0, the particle is speeding up when t > 1.67.
Therefore, the particle is speeding up after 1.67 seconds.

Write the equation of the line that passes through the points (-6,8) and (-6,2).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
x = -6
Step-by-step solution:
The two points you have are (-6, 8) and (-6, 2).
1) First, you want to find the slope.
The equation for slope is \(\frac{y_{2} - y_{1}}{x_{2} - x_{1}}\).
Let's have (-6, 8) be x_{1} and y_{1}, and (-6, 2 ) x_{2} and y_{2}.
So, you would get \(\frac{2 - 8}{-6 - (-6)}\)= \(\frac{-6}{0}\) = 0.
Since there is no slope, you know this is a horizontal or vertical line.
Because the two points have the same x- value, you know that it is a vertical line at x = -6.
You can see the two points and the line in the graph I've attached below.
A 2-column table with 9 rows. The first column is labeled x with entries negative 4, negative 3, negative 2, negative 1, 0, 1, 2, 3, 4. The second column is labeled f of x with entries 18, 9, 6, 3, 0, negative 3, negative 6, negative 9, negative 18. Based on the table, which best predicts the end behavior of the graph of f(x)? As x → ∞, f(x) → ∞, and as x → –∞, f(x) → ∞. As x → ∞, f(x) → ∞, and as x → –∞, f(x) → –∞. As x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞. As x → ∞, f(x) → –∞, and as x → –∞, f(x) → –∞.
The best prediction is
(C) x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.
What is interval?An interval is a set of real numbers between two given numbers called the endpoints of the interval.
Given:
x f(x)
-4 18
-3 9
-2 6
-1 3
0 0
1 -3
2 -6
3 -9
4 -18
As, from the table x increases, the value of f(x) decreases
i.e. Over time, when x → ∞, f(x) → –∞
and then x decrease, the value of f(x) increases
when x → –∞, f(x) → ∞.
Hence, best predicts the end behavior of the graph of f(x) is x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞.

The value of tan(3π/4) is -1. How does the value of tan(3π/4 – π) compare? Explain your reasoning.
Answer:
The value of tan(3π/4) is indeed -1.
Now, to evaluate tan(3π/4 - π), we can use the following trigonometric identity:
tan(a - b) = (tan(a) - tan(b)) / (1 + tan(a)*tan(b))
Applying this identity to the expression tan(3π/4 - π), we get:
tan(3π/4 - π) = (tan(3π/4) - tan(π)) / (1 + tan(3π/4)*tan(π))
Substituting the values of tan(3π/4) = -1 and tan(π) = 0, we get:
tan(3π/4 - π) = (-1 - 0) / (1 + (-1)*0) = -1
So the value of tan(3π/4 - π) is also -1, which is the same as the value of tan(3π/4).
In other words, the value of tan(3π/4 - π) is equal to the value of tan(3π/4) because π is equal to 180 degrees, which is a full rotation. Subtracting a full rotation from an angle simply results in an equivalent angle in the opposite direction. Thus, the values of tangent for both angles remain the same.

After considering the given data we conclude that the given width of the rectangle is 5x - 8, under the condition that the given area of the rectangle is 35x²-36x-32 and length of the rectangle is 7x + 4.
To evaluate the width of a rectangle given its area and length, we can apply the formula:
width = area / length
As we all know the area of the rectangle is 35x²-36x-32 square inches and its length is 7x + 4 inches.
So, staging these values in the formula above, we get:
width = (35x²-36x-32) / (7x + 4)
Here we have to perform polynomial division.
(35x²-36x-32) / (7x + 4)
