Therefore, the greatest number of file boxes that can be stacked is 12.
Use the power reducing fabulous rewrite the identity in terms of the first power of cosine
The power reducing formula for the fourth power of the cosine function is:
[tex]\cos ^4\theta=\frac{3}{8}+\frac{1}{2}\cos (2\theta)+\frac{1}{8}\cos (4\theta)[/tex]Replace θ=3x to find the expression for cos⁴(3x) in terms of the first power of the cosine function:
[tex]\begin{gathered} \cos ^4(3x)=\frac{3}{8}+\frac{1}{2}\cos (2\cdot3x)+\frac{1}{8}\cos (4\cdot3x) \\ \frac{3}{8}+\frac{1}{2}\cos (6x)+\frac{1}{8}\cos (12x) \end{gathered}[/tex]Therefore, the answer is:
[tex]\cos ^4(3x)=\frac{3}{8}+\frac{1}{2}\cos (6x)+\frac{1}{8}\cos (12x)[/tex]Use the second option to write this expression as input.
there is a linear relationship between the distance that a car drives and the amount of gas left in the tank of the car. the value of r2 for this linear relationship is 98.01%. what is the value of r?
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car is negative, and the value of r is -0.99
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car are negative because when a car travels a distance, it consumes fuel, and so fuel decrease with distance
Calculating the value of r
Given, r^2=98.01%
r^2=0.9801
r=±√0.9801
r=±0.99
Since r should be negative, so we pick the negative value and reject the positive value
r=-0.99

Answer: 2
Step-by-step explanation: 12 divided by 3 is 4 so 6 divided by 3 would be 2
⇒I will use the similarity theorem which works by proportion of sides in similar shapes.
⇒The side with magnitude 12 in the bigger triangle is proportional with the side with magnitude 4 in the smaller triangle
⇒The side with magnitude 6 in the bigger triangle is proportional with the side with magnitude x in the smaller triangle. The proportionality theorem allows us to equalize the proportions of the sides

Outward journey Speed = 20 km/hr , James stopped for 45 Mins ,Average speed homewars 15 km/hr
What is speed, for instance?
A measure of speed is the rate at which something is happening, moving, or moving swiftly. The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed.From graph Journey Started at 2PM
on 3PM James covered 20 km
Hence Speed = (20 - 0)/(3 -2) = 20 km/hr
outward journey Speed = 20 km/hr
Now outward Distance = 45 km
Time taken = 45/20 = 2 hr 15 min
Hence reached at 4 : 15 PM
Started home at 5 PM
James stopped for 45 Mins (3/4 hrs)
Reached back at 8PM
time taken = 8 - 5 = 3 Hrs
Distance = 45 km
Average speed homeward = 45/3 = 15 km/hr

Step-by-step explanation:
y = mx + b
b = -5 (the y-intercept)
m = 1/1 = 1
y = x - 5
Can anybody help me on this please? Does anyone see my question?
The slope of the line is represented by the word m which is obtained as 0.5.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To determine a line's inclination or steepness, use the slope formula. Calculating the ratio of the change in the y-axis to the change in the x-axis may be used to calculate the slope of any line.
From the graph, the data is observed as,
(x₁,y₁)=(0,1)
(x₂,y₂) = (-2,0)
The slope of the line is found as,
[tex]\rm m =\dfrac{0-1}{-2-0} \\\\ m = 0.5[/tex]
Thus, the slope of the line is represented by the word m which is obtained as 0.5.

Similarity Theorems
Triangles ABG and DCB are similar by the AA similarity postulate
"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"
The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.
On the other side, angles DBC and AGB are congruent also because they are both right angles.
With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options. 18 x minus 15 = 72 50 x minus 25 = 72 18 x minus 9 = 72 3 (6 x minus 3) = 72 x = 4.5
The equations with same value of x as (3/5)(30x - 15) = 72 is 18x - 9 = 72, 3(6x - 3) = 72 and x = 4.5
How to solve an equation?An equation shows the relationship between two or more numbers and variables.
Given the equation:
(3/5)(30x - 15) = 72
Opening the parenthesis:
18x - 9 = 72
Factorizing the equation:
3(6x - 3) = 72
Dividing through by 3:
6x - 3 = 24
6x = 27
Dividing through by 6:
x = 4.5
The solution to the equation (3/5)(30x - 15) = 72 yields x = 4.5

Answer:
x = 4 , x = 2.4
Step-by-step explanation:
[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5
multiply through by (x - 2)(x - 3)
4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)
4x - 12 + 3x - 6 = 5(x² - 5x + 6)
7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )
0 = 5x² - 32x + 48
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 48 = 240 and sum = - 32
the factors are - 20 and - 12
use these factors to split the x- term
0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )
0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term
0 = (x - 4)(5x - 12)
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4
