The rate of change of function 2 is greater than the rate of change (slope) of function 1 by: B. 2.
How to determine the difference in the rate of change?Since the line on this graph is perpendicular to the y-axis (horizontal line), we can reasonably and logically deduce that its rate of change (slope) is equal to zero (0) because there is no change in the y-value on the y-axis.
This ultimately implies that, the rate of change (slope) of function 1 (y = 6) with an horizontal line is equal to zero (0).
Next, we would calculate the rate of change (slope) of function 2 i.e y = 2x + 7. Mathematically, the standard form of the equation of a straight line function is given by;
y = mx + c
Where:
m represents the slope.x and y are the points.c represents the y-intercept.By comparing the two (2) equations, we have the following:
y = mx + c ≡ y = 2x + 7
Therefore, the rate of change (slope) of function 2 is equal to 2.
Now, we can calculate the difference between the rate of change (slope) of function 2 and the rate of change (slope) of function 1 as follows:
Difference = 2 - 0
Difference = 2.

While charting, a nurse notes that a patient has a medication infusing at 40.5 mL/hr. The label on the IV bag says 400 mg in 250 mL. How many mcg/min is the patient receiving?
The conversion factor you will need for this question is: 1 mg equals 1000 mcg
The amount that the patient is receiving, in mcg/min, using proportions, is of:
1008 mcg/min.
What is a proportion?A proportion represents a unit rate relative to a total amount, and this unit rate is used along basic arithmetic operations, especially multiplication and division, to find the desired measures in the context of a problem.
Considering than an hour has 60 minutes, the amount infused each minute is given as follows:
40.5/60 = 0.675 mL/min.
The rate of milligrams per milliliters is given as follows:
400/250 = 1.6 mg per mL.
Hence the number of mg received per minute is:
1.6 x 0.675 = 1.08 mg per minute.
1 mg equals 1000 mcg, hence the number of mcg received per minute is:
1.08 x 1000 = 1008 mcg/min.

An arrow released from a bow, traveling towards a target 200 yards away,
reaches a max height of 42.6 ft in only 1.5 seconds. What is the height of the
arrow at 2.5 seconds?
Thank you so much!
The height of the arrow at 2.5 seconds is 71 feet.
Given:
An arrow released from a bow, traveling towards a target 200 yards away,reaches a max height of 42.6 ft in only 1.5 seconds.
1.5 seconds = 42.6 feet
divide by 1.5 on both sides.
1 sec = 28.4 feet
0.5 sec = 28.4/2
0.5 sec = 14.2 feet
2.5 sec = 1.5 sec + 1 sec
= 42.6 + 28.4
= 71 feet

NO LINKS!! Please help me with the Segment Proofs Part 1
Answers in bold
GivenGivenDefinition of midpointTransitive property of equalityAddition property of equalitySimplificationSubstitutionSegment addition postulateTransitive property of equalityDivision property of equality====================================================
Explanation:
Always start the proof with what you are given. It seems silly to repeat the given information, but it's just how all proofs are formed. This is to build from those given statements to lead to what we want to prove on the last line.
The term "midpoint" refers to splitting a segment into two equal smaller pieces. So for instance, if Q is the midpoint of PR, then the pieces PQ and QR are equal. Each smaller piece is half as long as PR.
The transitive property is the idea if A = B and B = C, then A = C. Think of it like substitution. Or you can think of a set of dominoes: A knocks down B, which knocks down C. Therefore A knocks down C.
The addition property of equality is where we go from A = B to A+C = B+C. I've added C to both sides. Adding the same thing to both sides will not change the equation. It keeps things balanced. When going from line 4 to line 5, we added PQ to both sides.
In line 6, we've gone from PQ+PQ to 2PQ.
In line 7, we replace PQ with QR on the right hand side. We use the substitution property here (refer to line 3 where we found PQ = QR)
Line 8 uses the segment addition postulate. If A,B,C are collinear, then AB+BC = AC. The point B doesn't necessarily need to be the midpoint.
Line 9 uses the transitive property again (we combine lines 7 and 8 to lead to line 9).
The final line has us divide both sides by 2 to get what is shown in the table. This is the division property of equality.
------------------------
Shortcut using informal logic:
PQ = QR
QR is half as long as QS
Therefore, PQ is also half as long as QS
Answer:
The last reason for [tex]PQ=\frac{1}{2}QS[/tex] is division property of equality
Step-by-step explanation:
The reason for [tex]PQ=\frac{1}{2}QS[/tex] can be evaluated as follows
For the statement [tex]Q[/tex] is the midpoint of [tex]\overline{PR}[/tex], the reason is given
For the statement [tex]R[/tex] is the midpoint of [tex]\overline{QS}[/tex], the reason is given
For the statement [tex]PQ=QR, QR=RS[/tex] , the reason is definition of midpoint
The midpoint of a line segment is the point that separates the line segment into two congruent parts.
For the statement [tex]PQ=RS[/tex] , the reason is transitive property
Transitive property says that if [tex]a=b[/tex], and [tex]b=c[/tex], then [tex]a=c[/tex]
In this statement [tex]PQ=QR, QR=RS[/tex], then [tex]PQ=RS[/tex]
For the statement [tex]PQ+PQ=PQ+RS[/tex] , the reason is addition property of equality
Addition property of equality says that if [tex]a=b[/tex], then [tex]a+c=b+c[/tex]
For the statement [tex]2PQ=PQ+RS[/tex] , the reason is combining of like terms of algebraic expression
Combining like terms is the process to add or to substract the coefficient of the terms
In this statement combining like terms is at the left side of the equation, [tex]PQ+PQ=2PQ[/tex]
For the statement [tex]2PQ=QR+RS[/tex] , the reason is substitution property
Substitution property of equality says that if [tex]a=b[/tex], then [tex]a[/tex] replaces [tex]b[/tex] in any equation, in this statement [tex]QR[/tex] replaces [tex]PQ[/tex]
For the statement [tex]QR+RS=QS[/tex] , the reason is substitution property and definition of midpoint
In this statement [tex]QR+RS[/tex] replaces [tex]2PQ[/tex], and [tex]QS[/tex] is the sum of two congruent parts [tex]QR+RS[/tex]
For the statement [tex]2PQ=QS[/tex] , the reason is substitution property
In this statement [tex]2PQ[/tex] replaces [tex]QR+RS[/tex]
For the statement [tex]PQ=\frac{1}{2}QS[/tex] , the reason is division property of equality
Division property of equality says that if [tex]a=b[/tex], and [tex]c\neq 0[/tex], then [tex]\frac{a}{c} =\frac{b}{c}[/tex]
In this statement [tex]\frac{2PQ}{2} =\frac{QS}{2}[/tex] or can be reduced into [tex]PQ=\frac{1}{2}QS[/tex]

Given, a rectangle's length is 5.1 more than 2 times its width.
Its perimeter is 165.6.
Let the length of the rectangle be l,
breadth of the rectangle be b.
According to the question,
l = 5.1 + 2b
Using the formula of Perimeter,
Perimeter = 2(l + b)

what is 3 5/8 adding 1 2/8
Answer:
The solution is 4 7/8 or 39/8
Step-by-step explanation:
[tex] \sf 3 \frac{5}{8} + 1 \frac{2}{8} \\ \\ = \sf (3 + 1) + ( \frac{5}{8} + \frac{2}{8} ) \\ \\ = \sf 4 + \frac{7}{8} \\ \\ = \sf 4 \frac{7}{8} [/tex]
Or
[tex]\sf 3 \frac{5}{8} + 1 \frac{2}{8} \\ \\ = \frac{29}{8} + \frac{10}{8} \\ \\ = \sf \frac{39}{8} [/tex]
Determine whether the figure is a parallelogram using the distance formula.
Q\left(-10,-2\right),R\left(1,-1\right),S\left(1,-7\right),T\left(-11,-8\right)Q(−10,−2),R(1,−1),S(1,−7),T(−11,−8)
The distance formula used to determine if the figure is a parallelogram indicates;
The length of QR ≈ 11.0 and the length of ST ≈ 12.0. The length of QS ≈ 12.1, and the length of RT ≈ 13.9. Therefore, QRST is not a parallelogramWhat is a parallelogram?A parallelogram is a quadrilateral that have two pairs of facing sides that are parallel and of the same length.
The length of the sides can be found by using the formula for finding the distance between two points on the coordinate plane as follows;
The distance between the points (x₁, y₁) and (x₂, y₂) is d = √(x₂ - x₁)² + (y₂ - y₁)²
The length of QR = √((1 - (-10))² + (-1 - (-2))²) = √(122) ≈ 11.0
Length of ST = √((1 - (-11))² + (-7 - (-8))²) = √(145) ≈ 12.0
Length of QS = √((1 - (-10))² + (-7 - (-2))²) = √(146) ≈ 12.1
Length of RT = √((1 - (-11))² + (-1 - (-8))²) = √(193) ≈ 13.9
The lengths of the opposite sides of a parallelogram are the same. The lengths of the sides of the quadrilateral QRST are different, therefore, quadrilateral QRST is not a parallelogram.
