Function:
A function is defined as the an expression, rule, or law that defines a relationship between one independent variable and another dependent variable.
Given,
Here we have the function H(X) = 0.6X + 3.8 models the height in inches of a stack of X cups.
And we need to find the key features is at H(0).
To find the key feature at H(0), then we have to simple apply the value of X as 0,
Like the following, we have to replace the X value in the function with 0, then we get the expression like the following,
=> H(0) = 0.6(0) + 3.8
=> H(0) = 0 + 3.8
H(0) = 3.8

Omar gave out a survey to some students in his school about their favorite color. 650 of those surveyed said their favorite color was blue. If 65% of the students surveyed said their favorite color was blue, how many students were surveyed in total?
The total number of students surveyed by Omar in his school is 1000.
Here, we are given that Omar conducted a survey of some students in his school about their favorite color.
650 of those surveyed said their favorite color was blue.
Further, 65 percent of the students surveyed said their favorite color was blue.
Let the total number of students surveyed be x
Then, according to the given information,
65% of x is 650
Thus, we can form the following equation-
65/ 100 × x = 650
0.65x = 650
x = 650/ 0.65
x = 65000/ 65
x = 1000

What does it mean when a point is translated horizontally to the right by 6 units? That means its x coordinate is increased by 6 units, the y-coordinate is unchanged
(If it was translated 6 units to the left, it's x coordinate would decrease by 6 units)
So if we had a point say (1, 1) then its new x-coordinate will be (1+6, 1) or (7,1) The y-coordinate stays unchanged if the translation is horizontal
When a point is translated vertically by 6 units, its x-coordinate is unchanged but the new y coordinate is increased by 6 units (-6 units if the translation is vertically down)
So with a point (1, 1), an up translation will result in a new point (1, 7)
If both translations are applied both x and y coordinates will change to
(7, 7)
To figure out the new coordinates denoted by P'Q'R'S'T' of each of the points PQRST of the given figure:
Add 6 to the x-coordinate of each point and at the same time add 6 to the y-coordinate of that point
If you look at the graph, the original points and translated points for 6 units to right and 6 units up are
P(-3, -5) which translates to P'(-3 + 6, -5 + 6) or P'(3, 1)
The other new points are calculated the same way by adding 6 to both x and y coordinates
Q(-1, -5) ==> Q'(5, 1)
R(-1, -2) ==> R'(5, 4)
S(-3, -2) ==> S'(3, 4)
T(-3, -3) ==> T'(3, 3)
U(-5, -3) ==> U'(1, 3)
V( -5, -4) ==> V'(1, 2)
W(-3, -4) ==> W'(3, 2)
The attached graph shows the translated figure with the translated points. Essentially the original figure has been shifted 6 units to the right and 6 units up
26. Given: mABD = mFDB; m/1 = m/4
Prove: BC || ED
How would I solve this proof in a two column proof?
Following is the proof of BC||ED using alternate interior angles.
What is the property of alternate interior angles?According to the alternate angle theorem, when a transversal cuts two parallel lines, the resulting alternate interior angles or alternate exterior angles are congruent.
We are given the ∠ABD = ∠FDB
and
∠1 = ∠4
using the above-given conditions we need to prove that line BC is parallel to line BD (i.e. BC || BD)
∠ABD = ∠FDB...................................(i)
∠ABD= ∠1 +∠2
and
∠FDB= ∠3+∠4
now subsituting these values of ∠ABD and ∠FDB in equation(i)
we get,
∠1 +∠2=∠3+∠4
we are also given that ∠1 = ∠4, substituting that,
∠1 +∠2=∠3+∠1
= ∠2=∠3+∠1-∠1
= ∠2=∠3
through the given fig we know,
∠2=∠CBD
and
∠3=∠EDB
i.e.
∠CBD=∠EDB
∠CBD and ∠EDB make alternate interior angles of the lines BC and ED,
and since both the alternate interior angles are equal(∠CBD and ∠EDB) both the lines are parallel (||).
therefore we have BC||ED, hence proved.

Given the midpoint (M) and either endpoint of AB. find
the other endpoint.
A(-1, 2) and M(3,6)
a B is (7, 10)
b Bis (9, 12)
c B is (10, 10)
d B is (13, 10)
The other endpoint is (7,10).
Assuming that your midpoint M = (x, y) and endpoint A = (x1, y1) are both present: Coordinates of the double midpoints are 2x, 2y. To find the x-coordinate of the missing endpoint, subtract the known endpoint's x-coordinate from the first value: x₂ = 2x - x₁.
The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.
An alternate solution would be to substitute (-1, 2) for (x1,y1) and (3,6) for (x2,y2) into the midpoint formula:
(x - 1)/2 = 3
x -1 = 6
x =7
(y + 2)/2 = 6
y + 2 = 12
y =10
Solving each equation for (x2,y2) yields the solution (7,10).

The distance traveled by the tip of the minute hand in 45 minutes is approximately 256.77 mm, while the distance traveled by the tip of the hour hand in 1 hour is approximately 267 mm.
A) The hour needle completes a complete rotation of 12 hr, in 45 min = 0.75 hours, it will be 0.75 ÷ 12 of a complete rotation.
Given that the hour arrow's tip touches the rim of a clock, the radius of the clock is equal to the distance of the pointer.
The circumference of a circle is:
C=2 × π × radius
The span crossed by the hand in 12 hours is:
2 × 36=76π mm
The space traversed in 45 min is:
0.75 ÷ 12 × 72π=4.5π mm
in 45min, the min hand will make 45 ÷ 60=3 ÷ 4. If the min hand is 150% of the hour hand, then its length is 150 ÷ 100 × 36 = 54 mm.
As a result, the point of the minute will go around the complete circumference of a circle with a radius of 54 mm, implying that for a full circle, we will have:
2 × π × 54mm = 108π mm.
As a result, the minute hand's tip will have moved 45 minutes in 45 minutes, 108 × 3 ÷ 4 × π = 81π mm.
B) The clock's hour hand measures 30 mm.
As a result, the radius of the minute hand is,
1.5 × 30 = 45mm
And the minute hand moves after one hour 2π × ( r )²:
2 × 3.14 × 45 × 45 = 90π mm
And the minute hand moves,
π ÷ 6 × 30 = 5π mm
As a result, the minute hand moves,
90π - 5π = 85π mm

homeowner makes the trough from a rectangular piece of of aluminum that is 20 in. long and 12
in. wide. He makes a fold along the long sides a distance of x inches from the edge. If he wants the
trough to hold 360 in³ of water, how far from the edge should he make the fold?
Answer:20 in * (12 in - 2X in) * (X in) = 360 in3
This can be simplified by dividing both sides by 20 in:
20 in * (12 in - 2X in) * (X in) = (360 in3/ 20 in)
After dividing both sides by 20 in:
(12 in - 2X in) * X in = 18 in2
Distribute X in. across (12 in -2X in):
12X in2 - 2X2 in2 = 18 in2
1.Subtract 18 in2 from both sides:
12X in2 - 2X2 in2 - 18 in2 = 0
2. Rearrange the equation:
-2X2 in2 + 12X in2 - 18 in2 = 0
This for matches the form for a quadratic equation (Ax2 + Bx +C = 0)
You can then plug these values into the quadratic formula to solve for X

250 word minimum essay on the steps of solving for both the x and y intercept.
Answer:
Step-by-step explanation:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y and an x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system. To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis. When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. For example In algebra, 2-dimensional coordinate graphs have a horizontal axis, or x-axis, and a vertical axis, or y-axis. The places where lines representing a range of values cross these axes are called intercepts. The y-intercept is the place where the line crosses the y-axis and the x-intercept where the line crosses the x-axis. For simple problems, it is easy to find the x-intercept by looking at a graph. You can find the exact point of the intercept by solving algebraically using the equation of the line.
