The required equation to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours is,
⇒ | 200 - 65h | = 4.
Option B is correct.
We have to given that,
A train is moving at a rate of 65 miles/hour toward a railroad marker located 200 miles away.
Since, Distance is defined as the object traveling at a particular speed in time from one point to another.
Let the time be h and the distance traveled by train in time h is 65h.
Since at time h the distance between the train and rail road maker is 4 miles,
So the expression can be given as train traveled 65h distance to reduce the distance of 200 miles to 4 miles
| 200 - 65h | = 4
(MODULUS is used because distance can never be negative.)
Thus, the required equation to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours is | 200 - 65h | = 4.

The graphs below have the same shape. What is the equation of the blue
graph?
Answer:
\(\text{C. }g(x)=(x-5)^2\)
Step-by-step explanation:
The function \(y=(x-c)^2\) has a phase shift of \(c\) to the parent function \(y=x^2\). Since \(g(x)\) has moved to the right 5 units from the parent function \(f(x)=x^2\), we're looking for a value of \(c=5\).
Therefore, we have:
\(g(x)=\boxed{(x-5)^2}\)

A farmer plans to build the small silo shown to store chicken feed. What is the circumference of the base of the silo if it can hold a maximum of 132 cubic feet of feed?
The circumference of the base of the silo that can hold a maximum of 132 cubic feet of feed is approximately 28.796 feet.
How to determine the circumference of the base of a silo
The circumference is the measure of the contour of a circle. In this question we have to determine the radio of the base of the cone from the volume formula and later the circumference is found by this finding:
Volume
V = (π/3) · R² · h (1)
Circumference
s = 2π · R (2)
Where:
R - Radius of the base, in feeth - Height of the silo, in feetIf we know that V = 132 ft³, h = 6 ft, then the circumference that can hold the given capacity is:
\(R = \sqrt{\frac{3\cdot V}{\pi \cdot h} }\)
\(R = \sqrt{\frac{3\cdot (132\,ft^{3})}{\pi\cdot (6\,ft)} }\)
R ≈ 4.583 ft
s = 2π · (4.583 ft)
s ≈ 28.796 ft
The circumference of the base of the silo that can hold a maximum of 132 cubic feet of feed is approximately 28.796 feet. \(\blacksquare\)
RemarkThe statement is complete, complete form is introduced below:

Find the sum of the first 16 terms of an arithmetic sequence where a4=7 and a7= 16. (I need the procedure y Example) please
Answer:
S₁₆ = 328
Step-by-step explanation:
the nth term of an arithmetic sequence is
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₄ = 7 and a₇ = 16 , then
a₁ + 3d = 7 → (1)
a₁ + 6d = 16 → (2)
subtract (1) from (2) term by term to eliminate a₁
0 + 3d = 9
3d = 9 ( divide both sides by 3 )
d = 3
substitute d = 3 into (1) and solve for a₁
a₁ + 3(3) = 7
a₁ + 9 = 7 ( subtract 9 from both sides )
a₁ = - 2
the sum to n terms of an arithmetic sequence is
\(S_{n}\) = \(\frac{n}{2}\) [ 2a₁ + (n - 1)d ]
with a₁ = - 2 and d = 3 , then
S₁₆ = \(\frac{16}{2}\) [ (2 × - 2) + (15 × 3) ]
= 8(- 4 + 45)
= 8 × 41

Determine the equation of the circle graphed below.
The circle has a diameter of 10 and a radius of 5
the radius times itself ( 5 x 5 ) = 25
25 times pi (3.14) = 78.5
so the circle is 78.5, lets say square cm.
and the circumference is 31.41593 or 31.42
we need to find the center point and the length of the radius. The center point is at 5. 1. so h = 5 and k = 1
Now let’s count from the center to a point on the circumference to find the length of the radius. 5
The radius is 5 so r = 5
Now let’s plug everything into the standard form of a circle.
(x - h)²+ (y - k)² = r²

Brainlist
Answer:
12 gallons
Step-by-step explanation:
Given the following :
Total amount of gas used by aircraft = 51 gallons
Flight departure time = 9:30 a.m
Arrival time of flight = 1:45p.m
Number of hours traveled by flight:
Arrival time - Departure time
1:45pm - 9:30a.m = 4hrs 15 minutes = [(60*4)+15] minutes = 240 + 15 = 255 minutes
Amount of gallons used per hour :
255 minutes = 51 gallons
I minutes = x
255x = 51 gallons
x = 51 / 255
x = 0.2 gallons
0.2 gallons per minute
1 hour = 60 minutes
Number of gallons per hour = (0.2 * 60) = 12 gallons

Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water. W represents the volume of water Andrei uses (in liters) if he uses n marbles.
W = 32 – 0.05n
What is the glass tank's volume? how many liters?
Answer:
640
Step-by-step explanation:
=32-0.05W
We move all terms to the left:
-(32-0.05W)=0
We add all the numbers together, and all the variables
-(-0.05W+32)=0
We get rid of parentheses
0.05W-32=0
We move all terms containing W to the left, all other terms to the right
0.05W=32
W=32/0.05
W=640
Consider the absolute value function f(x) = |3x − 6|. what is the vertex of the function?
A vertex can be found in many different kinds of graphs. The graphs of the quadratic function and the absolute value function are two examples of this. The graph's vertex is where the direction of the line changes.
what is the vertex of the function?Using the conventional equation \(y = ax_2 + bx + c\), obtain h(x-coordinate of the vertex) = -b/2a, and then locate y at h to obtain k. (the y-coordinate of the vertex).
Absolute value equations are those in which a variable is enclosed by an absolute value operator, such as \(\[|3x-6|\]\)A number's absolute value is determined by its sign; if it is positive, it is equal to the number: \([|5|=5\]\). The absolute value of a number is its opposite if it is negative: \(\[|-5|=5\]\). So, when working with a variable, we must take into account both scenarios.
In the indicated equation, \(\[y=a|x-h|+k\].\) Variable x exists. Allow m to be the equation's slope. slope \(\[m=a\]\) on the right side of the vertex that is \([x > h\]\) and slope \(\[m=-a\]\) The vertex is [x] on its left side. We must locate an absolute value equation's vertex in order to answer the query.
the center of an equation with absolute values \(\[y=a|x-h|+k\]\)is \(\[(h,k)\].\)Looking at the equation that is can help us locate a vertex. \(\[(h,k)\]\). As a result, by examining it, we may determine the vertex of an equation for absolute value, which is \(\[(h,k)\] [y=a|x-h|+k\]\).

define a function that transforms the parent root function with a horizontal compression by a factor of 5 and a downward shift of 10 units
a function that transforms the parent root function with a horizontal compression by a factor of 5 and a downward shift of 10 units is: \(f(x) = \sqrt[n]{5x} -10\)
What is function?The function is a mathematical phrase, rule, or law that establishes the connection between an independent variable and a dependent variable (the another variable).
A function is described as a relationship between a group of inputs and one output each. A function is, to put it simply, a connection between inputs in which each input is connected to exactly one output.
Parent root function is given by:
\(f(x) = \sqrt[n]{x}\)
According to rules-
Compression would be achieved by multiplying the by 5. So, we would have: \(\sqrt[n]{5x}\)Downward vertical shift would be achieved by adding a to the function.So, \(\sqrt[n]{x}-10\)Combining these 2 transformation gives us the function: \(f(x) = \sqrt[n]{5x} -10\)

What distinguishes a mathematical element?The elements or members of a set are the parts that make it up. To divide the components of a set, commas and two curly (idle) braces are typically employed. Capital letters are always used to print the set's name. The set "A" in this context consists of the letters v, w, x, y, and z.
Based on the given diagram and instructions, it appears that the error in the construction is that the first arc is centered at point C instead of point A. The correct procedure for constructing a line parallel to line AB and passing through point P is as follows:
1.Draw a line AB and mark point P not on line AB.
2.From point P, draw an arc that intersects line AB at points D and E.
3.Draw another arc, centered at point D, with the same radius as the first arc. This arc should intersect the first arc at point F.
4.Draw a line through point P and point F. This line is parallel to line AB and passes through point P.
So the answer is: the first arc should pass through point B (not A). All other elements in the diagram appear to be correct.
