Work Shown:
x = smallest side
y = medium side
z = largest side
x = y-79
z = y+377
x+y+z = perimeter
x+y+z = 3064
(y-79) + (y) + (y+377) = 3064
3y + 298 = 3064
3y = 3064-298
3y = 2766
y = 2766/3
y = 922
x = y-79
x = 922-79
x = 843
z = y+377
z = 922+377
z = 1299
------------------
Summary:
x = 843, y = 922, z = 1299
Check:
x+y+z = 843+922+1299 = 3064
which matches the given perimeter, so the answer is confirmed.

The equation c+d=58 represents the sum of the two numbers.
The equation c+d=58 represents the sentence "The first number is 8 less than half the seco
The equation C=d-8 represents the relationship between the two numbers.
The equation C=d-8 represents the sum of the two numbers.
The number d is 14.
The number c is 44.
The number is 14
Answer:
The following are the correct choices
First : The equation c + d represents the sum of the two numbers
Third: The equation c = (1/2)d - 8 represents the relationship
and the last choice : The number c is 14
Step-by-step explanation:
Translate the word problem into equations and solve for c and d where c is the first number and d the second
Sum is 58 translates to
c + d = 58 (1) ===> First choice
First number is 8 less than half the second number translates to
c = (1/2)d - 8 (2) ==> Third choice
Multiply equation (2) by 2 on both sides giving
2c = d - 16 ==> 2c - d = -16 (3)
Add equations (1) and (3) giving
c + d + 2c - d = 58-16
3c = 42
c = 42/3 = 14 ===> Last choice
Substituting for c in equation (1) gives
14 + d = 58
d = 44

The [tex]\lim_{x \to 1} 7x-3=7(1)-3=4[/tex] using the ε − δ definition of a limit.
The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are also required to determine continuity, derivatives, and integrals.
The limit of f(x) at x = c is L according to the epsilon-delta definition of limits if ε > 0 there's a δ > 0 such that if the distance of x from c is less than, then the distance of f(x) from L is less than ε. The idea that we can approach L as closely as we like is expressed in this way.
[tex]\lim_{x \to a}f(x)= L[/tex] if ∀ ε > 0, ∃ δ > 0
0 < | x − a| < δ
⇒ | f(x) − L | < ε
Now, consider the limit
[tex]\lim_{x \to 1} 7x-3=4[/tex]
Here, f(x) = 7x - 3, a = 1, L = 4
Proof:
∀ ε > 0, ∃ δ = ε > 0
0 < | x - 1 | < δ

If X = 6 units, Y = 8 units, and h = 6 units, what is the area of the trapezoid?????????
-7th
The area of the trapezoid is 42 square units
How to determine the areaThe formula for area of a trapezoid is expressed as;
Area = a + b/ 2 h
Where;
a is the length of the side = 6 unitsb is the length of its base = 8 unitsh is the height of the trapezoid = 6 unitsNow, to determine the area of the trapezoid, we need to substitute the values of the length of the side and its base with the height of the trapezoid.
Substitute the value into the equation
From the above information, we have that;
Area = 6 + 8/ 2 (6)
Find the quotient
Area = 14/ 2(6)
Area = 7(6)
Multiply through
Area = 42 square units
We have that the area of the trapezoid takes the value 42 square units

Can someone provide an example and counter example of a function ?
Answer:
A weekly salary is a function of the hourly pay rate and the number of hours worked
Step-by-step explanation:
a function is a map assigning values of a result or solution set to values of a set of initial or starting values.
we typically name these starting values x and the solution values f(x) or y (the results "created" out of x).
we often say
y = f(x)
and provide an expression or table to explain the logic of the mapping between x and f(x).
the only rule to be a function and not just a general relationship between these 2 sets :
every value in the set of starting values must have exactly one assigned solution value. not 0, not 2 (or more). one and only one.
but yes, different values of x can have the same assigned solution value. that is not a problem for a function. it just cannot be the other way around. there cannot be different solution values assigned to the same value of x.
so, a typical example of a function is a line.
e.g.
y = f(x) = 5x + 12
for every value of x you could think of (and everything else) there is exactly one result value calculated.
or the score board in a sports event :
athlete 1 : 12 points
athlete 2 : 24 points
athlete 3 : 20 points
athlete 4 : 22 points
...
the athletes are the "x". and their associated points the "f(x)" or "y".
no athlete is listed multiple times with different scores.
a typical example of not being a function is a circle. for almost every value of x inside the circle (that means for almost every point of the horizontal diameter of the circle) there are 2 values of y (that means points on the arc of the circle) : one above and one below the diameter.
or a strange score board like
athlete 1 : 12 points
athlete 2 : 24 points
athlete 3 : 20 points
athlete 2 : 22 points
athlete 4 : 22 points
...
athlete 2 is listed twice with 2 different scores.
so, this is therefore not a function.
The announcer said, ingrid won the 100 metre race in 13.9 seconds. Her time was originally measured to 2 decimal places. What was the slowest time she could have run?
Answer:
13.94 seconds
Step-by-step explanation:
The greatest number with 2 decimal places that can be rounded to 13.9 is 13.94.
Answer: 13.94 seconds
The announcer said that Ingrid has won the race in 13.9 seconds, then the slowest time she could have run is 13.94 seconds.
What is approximation?Something similar to something else but not precisely the same is called an approximation. By rounding, a number can be roughly estimated.
By rounding the values in a computation before carrying out the procedures, an estimated result can be obtained.
13.94 is the largest number that can be rounded to the nearest two decimal places and be equal to 13.9.
Because after the second decimal, that is 4 the number has to increase as per the rules of approximation. That's why the number 13.94 up to two decimal places is correct.

The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases
How to prove: The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases?From the figure, we have the following coordinates
B = (a, 0)
D = (d, c)
The midpoint of line segment BD is calculated as
BD = 1/2 * (x1 + x2, y1 + y2)
So, we have
BD = 1/2 * (a + d, 0 + c)
This gives
BD = ((a + d)/2, c/2)
Also, we have:
Lines MN and AB are horizontal lines
This means that they have a slope of 0
i.e.
Slope of AB = Slope of MN = 0
Parallel lines have equal slope
Hence, the segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases

Which answer correctly describes the transformation from segment MR to segment M′R′?
Answer:
The transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)" ⇒ B
Step-by-step explanation:
Let us revise some transformationIf the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y) ⇒ R(180, O) (x, y) → (-x, -y) If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k) ⇒ T (x, y) → (x, y + k)∵ The coordinates of the point R = (-2, 4)∵ The coordinates of point R" = (3, -3)→ Both coordinates in R" have opposite signs then R∴ R rotated 180° about the origin ⇒ using the 1st rule above∴ R' = (2, -4)→ Find the difference between the x-coordinate of R" and x-coordinate of R'∵ xR" - xR' = 3 - 2 = 1→ By using the 2nd rule above∴ R' translated 1 unit to the right → Find the difference between the y-coordinate of R" and y-coordinate of R'∵ yR" - yR' = -3 - (-4) = -3 + 4 = 1→ By using the 3rd rule above∴ R' translated 1 unit up∴ The rule of translation is T(x, y) ⇒ (x + 1, y + 1)Let us use these 2 rules on S to find S"∵ The coordinates of the point S = (-4, -1)∵ S is rotated 180° around the origin→ By using the 1st rule above, opposite the signs of its coordinates∴ S' = (4, 1)∵ S' translated 1 unit right→ By using the 2nd rule above, add its x-coordinate by 1∵ S' translated 1 unit up→ By using the 3rd rule above, add its y-coordinate by 1∴ S" = (4 + 1, 1 + 1)∴ S" = (5,2)→ That means the rules of transformation of point R is rightThe transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)"

A natural log is a logarithm with the base "e." It is represented by the symbol "ln." In other words, loge = ln. In other words, the natural logarithm lacks a base. When "ln" is recognized automatically, "e" is assumed to be its base. The same set of logarithmic rules applies to all logarithms, including the natural logarithm. As a result, the following are the key natural log rules (also known as ln rules):
ln (mn) = ln m + ln nln (m/n) = ln m - ln nln mn = n ln mln a = (log a) / (log e)ln e = 1ln 1 = 0log∨b m = x ⇒ m = b∧xlog∨e(3x)=23x=e²x=e²/3Therefore the final answer for the given question is x=e²/3
