Each face of a cube has an area of 4 square units, then the volume of the cube is 8 cubic units.
The given information states that each face of the cube has an area of 4 square units.
Since a cube has 6 faces, this means that the total surface area of the cube is:
Total Surface Area = 6 * 4 square units = 24 square units
Now, let's relate the surface area of the cube to its volume:
For a cube, the surface area (S) and the volume (V) are related by the formula:
S = 6s²
Where "s" is the length of each side of the cube. In this case, we have:
S = 24 square units
Substitute this into the formula:
24 = 6s²
Now, solve for "s":
s² = 24 / 6
s² = 4
Take the square root of both sides:
s = √4
s = 2
So, each side of the cube is 2 units long.
Now, to find the volume of the cube, you can use the formula for the volume of a cube:
V = s³
Substitute the value of "s":
V = 2³
V = 8 cubic units
Therefore, the volume of the cube is 8 cubic units.

Find the average rate of change from x = 1 to x=5
Answer:
The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
Therefore the slope, or the average rate of change, between these points is 2.

b + 1.5 = 6
solve the equation and find the value of the variable
Answer:
[tex]\boxed{\sf{b=4.5}}[/tex]Step-by-step explanation:
To find the value of variable, you have to isolate the term of b from one side of the equation.
b+1.5=6First, you subtract by 1.5 from both sides.
→ b+1.5-1.5=6-1.5
Solve.
Subtract the numbers from left to right.
⇒ 6-1.5=4.5
⇒ b=4.5
Therefore, the correct answer is b=4.5.I hope this helps you! Let me know if my answer is wrong or not.

What is the magnitude and direction of RS with tail and head points R(4, -6) and S(-2, 1)?
9.2 units, 49.4° north of west
10.4 units, 40.6° north of west
9.2 units, 49.4° south of east
10.4 units, 40.6° south of east
Using vector concepts, it is found that the correct option regarding the magnitude and the tail is given by:
9.2 units, 49.4° north of west
How do we find the vector, and what is it's magnitude?To find them, we subtract the end coordinate by the start coordinate, hence:
RS = S - R = (-2, 1) - (4,-6) = (-6,7).
The magnitude is given by the square root of the sum of the squares of each coordinate, hence:
[tex]|RS| = \sqrt{(-6)^2 + 7^2} = \sqrt{85} = 9.2[/tex]
Considering a xy graph, the vector is decaying, that is, moving north of west, hence the correct option is:
9.2 units, 49.4° north of west

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

I have 90 because of the right angle. That is a 90-degree angle.
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.

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
