Answer:the cycle repeats every 2pi radians
Step-by-step explanation:
Answer:
The statement which does not describe the tangent function is A. The cycle repeats every 2pi radians.
Step-by-step explanation:
Tangent functionThe tangent function is the ratio of the length of the opposite side to that of the adjacent side. It is also described as the ratio of sine and cos .
If we analyses the tan function graph we will happened to find that it repeats itself after every π radian .
So, its cycle cannot repeat every 2pi radians.
Therefore, The statement which says that The cycle repeats every 2pi radians does not describe the tangent function.

Kaizen is a Japanese word that means continuous development. It says that each day we should focus on getting 1% better on whatever we're trying to improve.
How much better do you think we can get in a year if we start following Kaizen today?
Note: You can take the value of
(1.01)^365 as 37.78.
Answers
If we follow Kaizen's principle and improve by 1% each day, we can get approximately 37.78 times better in a year.
If we follow Kaizen's principle of improving by 1% each day, we can calculate how much better we will get in a year by using the formula:
Final Value = Initial Value x (1 + Daily Improvement Percentage)^Number of Days
Since we are trying to calculate how much better we can get in a year, we can plug in the following values:
Initial Value = 1 (assuming we are starting from our current level of performance)
Daily Improvement Percentage = 0.01 (since we are trying to improve by 1% each day)
Number of Days = 365 (since there are 365 days in a year)
Using these values, we get:
Final Value = 1 x (1 + 0.01)³⁶⁵
Final Value ≈ 1 x 37.78
Final Value ≈ 37.78
This shows the power of continuous improvement and the importance of consistent effort towards our goals.

Multiply.
2x^4 (3x³ − x² + 4x)
Answers
Answer: A
Step-by-step explanation:
When multiplying: Numbers multiply with numbers and for the x's, add the exponents
If there is no exponent, you can assume an imaginary 1 is the exponent
2x⁴ (3x³ − x² + 4x)
= 6x⁷ -2x⁶ + 8x⁵
Answer:
A. \(6x^{7} - 2x^{6} + 8x^{5}\)
Step-by-StepLabel the parts of the expression:
Outside the parentheses = \(2x^{4}\)
Inside parentheses = \(3x^{3} -x^{2} + 4x\)
You must distribute what is outside the parentheses with all the values inside the parentheses. Distribution means that you multiply what is outside the parentheses with each value inside the parentheses
\(2x^{4}\) × \(3x^{3}\)
\(2x^{4}\) × \(-x^{2}\)
\(2x^{4}\) × \(4x\)
First, multiply the whole numbers of each value before the variables
2 x 3 = 6
2 x -1 = -2
2 x 4 = 8
Now you have:
6\(x^{4}x^{3}\)
-2\(x^{4}x^{2}\)
8\(x^{4} x\)
When you multiply exponents together, you multiply the bases as normal and add the exponents together
\(6x^{4+3}\) = \(6x^{7}\)
\(-2x^{4+2}\) = \(-2x^{6}\)
\(8x^{4+1}\) = \(8x^{5}\)
Put the numbers given above into an expression:

What is the relationship between the volume of a rectangular prism and the volume of a pyramid with the same height and base?
Answers
The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.
How to find the volume of a rectangular prism and pyramid?
The formula for the volume of a rectangular prism is:
Volume = Length * Width * Height
The formula for the volume of a pyramid is:
Volume = (Base Area * Height) / 3
The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.
This is because the volume of a rectangular prism is calculated by multiplying its three dimensions together, whereas the volume of a pyramid is calculated by multiplying the base area by the height and dividing the result by 3.
Hence, the volume of the rectangular prism is greater than the volume of the pyramid with the same height and base. This is because the rectangular prism has additional volume in the form of its width, which the pyramid does not have.

Find four numbers forming a geometric sequence such that the second term is 35 less than the first term and the third term is 560 more than the fourth term. Show your work.
Answers
Four numbers forming a geometric sequence such that the second term is 35 less than the first term and the third term is 560 more than the fourth term are -35/3, -140/3, - 560/3, -2240/3 and 7, -28, 112, - 448
Four numbers forming a geometric sequence can be calculate as follows
these terms: a₁, a₂, a₃, a₄
a₁ = a₂ + 35
a₃ = a₄ + 560
Use the formula for the n-term:
a₂ = a₁r
a₃ = a₁r²
a₄ = a₁r³
replace
a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35
a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560
Subtracting from the first equation to the second:
r² = 560/35
r² = 16
r = √16
r = ± 4
Use the first equation to find the first term:
a₁( 1 ± 4) = 35
1. a₁ = 35/-3 = -35/3
2. a₁ = 35/5 = 7
We have two sequences:

Mr. Schwartz builds toy cars. He begins the week with a supply of 85 wheels, and uses 4 wheels for each car he builds. Mr. Schwartz plans to order more wheels once he has fewer than 40 wheels left.
The inequality that can be used to find the number of cars, x, Mr. Schwartz builds before he places an order for more wheels is − x < 40.
Mr.Schwartz will need to order more wheels after building cars.
Answers
Mr. Schwartz will need to order more wheels after building 12 cars.
The number of cars x Mr. Schwartz builds before he places an order for more wheels can use the following steps:
Determine how many wheels are used per car:
4 wheels/car
Determine the number of wheels available at the start of the week:
85 wheels
Determine the minimum number of wheels needed to be available before placing an order:
40 wheels
Set up an inequality to represent the situation using x to represent the number of cars built before an order is placed:
Number of wheels used = 4x
Number of wheels remaining = 85 - 4x
Order is placed when number of wheels remaining is less than 40:
85 - 4x < 40
Solve for x by isolating the variable:
85 - 4x < 40
-4x < -45
x > 11.25
Since x represents the number of cars built can't have a fractional value for x.
The nearest integer to get the minimum number of cars that need to be built before an order is placed:
x > 12

suppose there are three cards, a, b, and c. two of them will be drawn one by one with replacements. what is the probability of getting (a, b), i.e. the first card is a and the second card is b?
Answers
the probability of getting (a, b), i.e. the first card is a and the second card is b is 2/3 by conditional probability.
The potential of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is computed by dividing the likelihood of the earlier occurrence by the likelihood of the subsequent, or conditional, event.
This is where the independent event and dependent event notion is used. Consider a student who misses class twice each week, omitting Sunday. What are the possibilities that he will take a leave of absence on Saturday of the same week if it is known that he will be absent from school on Tuesday? It has been noted that situations where the outcome of one event influences the outcome of a subsequent event are termed as conditional probability
We can work this out directly from the definition of conditional probability,
\(P(G_1|G_2)=P(G_1nG_2)/(P(G_1)\)
Exactly one of the three cards has sides, so
P(G1∩G2)=1/3
and P(G1)=1/2
THEN
the probability of getting (a, b), i.e. the first card is a and the second card is b IS = 1/3÷1/2 = 2/3

Convert the integral ∫∫ r √4 −x2−y2da where r = {(x, y) : x2 y2≤ 4, x ≥ 0} to polar coordinates, and then evaluate.
Answers
The integral ∫∫ r √4 −x2−y2da where r = {(x, y) : x2 y2≤ 4, x ≥ 0} conversion to polar coordinates the value of the integral is (4/3)π.
To convert the integral to polar coordinates, we need to express the limits of integration in terms of the polar coordinates.
Recall that in polar coordinates, x = r cosθ and y = r sinθ, where r is the radial distance from the origin and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin to the point (x, y).
In this case, the region r is defined by \(x^2 + y^2\) ≤ 4 and x ≥ 0. In polar coordinates, this corresponds to the region 0 ≤ r ≤ 2 and 0 ≤ θ ≤ π/2. To see why, note that x ≥ 0 implies 0 ≤ θ ≤ π/2, and \(x^2 + y^2 = r^2\), so r ≤ √4 = 2.
So we have:
∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(r=0 to 2) r√(4-\(r^2\)) dr dθ
To evaluate this integral, we can use the substitution u = 4 - \(r^2\), du = -2r dr, which gives:
∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) ∫(u=4 to 0) -1/2 √u du dθ
Now we can evaluate the inner integral:
∫(u=4 to 0) -1/2 √u du = [-1/3 u^(3/2)](u=4 to 0) = (1/3)(8 - 0) = 8/3
Substituting this back into the original integral, we have:
∫∫ r √4 −x2−y2da = ∫(θ=0 to π/2) (8/3) dθ = (8/3) (π/2 - 0) = (4/3)π
Therefore, the value of the integral is (4/3)π.
