Step-by-step explanation:
Hope this helps
The complete statement is, on a linear graph, the rate of change is called the slope of a line.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
From the above concepts we now know that, on a linear graph, the rate of change is called the slope of a line.
It can also be defined as, (y₂ - y₁)/(x₂ - x₁).

If f(x) is a linear function such that f(2)= 5 and f(4) = 13, f(x) = ?
A) 3x - 4
B) 4x - 3
C) 4x + 3
D) 1/4x + 9/2
Answer: you are on your own.
Step-by-step explanation:
The equation of the linear function f(x) is f(x) = 4x - 3. So, the answer is B) 4x - 3.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
We can use the two given data points to determine the equation of the linear function f(x) using the slope-intercept form:
f(x) = mx + b
where m is the slope and b is the y-intercept.
First, we can find the slope of the function by using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (2, 5) and (x₂, y₂) = (4, 13)
m = (13 - 5) / (4 - 2) = 4
Now we can use the slope and one of the given points to solve for the y-intercept:
5 = 4(2) + b
b = -3
Therefore, the equation of the linear function f(x) is f(x) = 4x - 3.

A cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm, what was its radius (in mm) before deformation
The radius of the copper specimen before deformation was 8 mm of a cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm
Given information:
Ductility (%el) of cold-worked copper = 25%Cold-worked radius = 10 mmTo find the radius of the copper specimen before deformation, we'll use the formula for calculating the ductility:
Ductility (%el) = ((Final radius - Initial radius) / Initial radius) * 100
Let's denote the initial radius as "r" (in mm). The final radius is 10 mm (after cold-working).
25% = ((10 - r) / r) * 100
Now, solve for "r":
25% = (10 - r) / r
Convert percentage into fraction:
25/100 = (10 - r) / r
Convert fraction into decimal:
0.25 = 10 - r/r
on Cross-multiplication gives:
0.25r = 10 - r
Add r on both sides gives,
1.25r = 10
On dividing by 1.25 gives:
r = 8 mm
So, the radius of the copper specimen before deformation was 9.75 mm.

An IV solution of 320 mL at a drip rate of 25 gtt/min using a tubing factor of 10 gtt/mL has been ordered to be initiated at 1145. Calculate the infusion time. (Round your answer to the nearest tenth of an hour.)
The infusion time for the IV solution that was prescribed = 128 mins.
Calculation of IV infusion timeTo calculate the infusion time the formula for IV drip rate is used which is;
Drip rate = volume/time × Drop factor
Drip rate = 25gtt/min
Volume = 320mL
Drop factor= 10 gtt/mL
Time = ?
From the formula above, make time the subject of formula. That is,
Time = vol × drop factor/drip rate
= 320 × 10/25
= 3200/25
= 128 mins
Therefore, the infusion time for the IV solution that was prescribed = 128 mins

Answer:
V = 54π or V = 169.56 units³
Step-by-step explanation:
The volume of a cylinder is given by the formula:
V = πr²h
If we use 3.14 as pi we get this:
V = (3.14)×(3)²×(6)
V = 3.14×9×6
V = 3.14×54
V = 169.56
Since it is volume the units will be units³
So our final answer is 169.56 units³
If you wanted an exact in pi form you would do the same steps but not simplify pi:
V = πr²h
V = π×(3)²×6
V = π×9×6
V = 54π

Allie identifies the coordinates of point D as (3, 7). Explain her error and explain how to correctly identify the ordered pair. hurry
Here Allie mistook the x and y axis completely oppositely.
→ First should be the x axis and then the y axis, (x, y)
Answer:
Step-by-step explanation:
Coordinates of a point are usually represented by (x, y) where x describes the horizontal distance from the y-axis and y describes the vertical distance from the x-axis.
Point A
4 units from the y-axis ⇒ x = 4
6 units from the x-axis ⇒ y = 6
A = (4, 6)
Point B
2 units from the y-axis ⇒ x = 2
9 units from the x-axis ⇒ y = 9
B = (2, 9)
Point C
0 units from the y-axis ⇒ x = 0
4 units from the x-axis ⇒ y = 4
C = (0, 4)
Point D
Allie has mixed up the x and y coordinates of D.
7 units from the y-axis ⇒ x = 7
3 units from the x-axis ⇒ y = 3
D = (7, 3)

What is the area of the composite figure? (6π 4) cm2 (6π 16) cm2 (12π 4) cm2 (12π 16) cm2
The area of the considered composite figure is given by: Option: 6π + 16 cm²
How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
For this case, the missing image is attached below.
As visible, the area of the figure = Sum of area of those 3 semi circles + Area of that square(its square because it has 4 equal sides in which adjacent sides are perpendicular) in between.
The side of the square is of 2+2=4 cm( as half of its side is 2 cm), thus, Area of that square = 4² = 16 cm²
All those 3 semicircles has radius = 2 cm
Since radius is same, so area of those 3 semicircle is same = [tex]\dfrac{\pi r^2}{2} = \dfrac{\pi (2)^2}{2} = 2 \pi\: \rm cm^2[/tex]
Thus, we get:
Area of the composite figure = [tex]2 \pi +2 \pi +2 \pi + 16 \: \rm cm^2 = 6 \pi+ 16 \: \rm cm^2[/tex]
