Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.
Answer:
n < 0
Step-by-step explanation:
Given that:
A number less than 0
Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.
From the following answer chioce:
[A] n=0
[B] n greater than n 0
[C] n greater then n with a underscore on the bottom 0
[D] n greater than 0 with a underscore 0
We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.
I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.
< → less than
> → greater than
A number less than 0 ⇒ n < 0

find f. f '(t) = sec(t)(sec(t) tan(t)), − 2 < t < 2 , f 4 = −7
This problem can be solved with integration. The first step is to integrate f '(t) dt. We use the integration formula for this purpose.The function f(t) has been found using the differential equation f'(t) = sec(t)(sec(t) tan(t))
f '(t) = sec(t)(sec(t) tan(t))
Integral calculus is used to find f(t) since it deals with derivatives.
Let's solve it.
f '(t) = sec(t)(sec(t) tan(t)) f(t) = ∫f '(t) dt
Using the integration formula,
f(t) = ∫ sec^2(t)dt = tan(t) + C [where C is the constant of integration]
f(t) = tan(t) + C
Now we have f(4) = -7. To find the value of C, we'll use
f(4) = -7=tan(4) + C7 = 1.1578 + C C = -7 - 1.1578 = -8.1578
Thus, the function
f(t) = tan(t) - 8.1578.
Therefore,The function f(t) has been found using the differential equation f'(t) = sec(t)(sec(t) tan(t))
In conclusion,f '(t) = sec(t)(sec(t) tan(t)) has been solved using integration. The value of the constant of integration, C, was found using the value of f(4) = -7. The function f(t) = tan(t) - 8.1578 is the solution to the differential equation.

Which geometric series results in a sum of -69,905
Using geometric sequence concepts, it is found that the one which results in a sum of -69,905 is:
D. \(\sum_{k = 0}^{9} -\frac{1}{5}(4)^k\)
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.As a sum, it can be represented by:
\(\sum_{k = 0}^{n - 1} a_1(q)^k\)
In which \(a_1\) is the first term.The result of the sum is:
\(S = \frac{a_1(1 - q^n)}{1 - q}\)
Item A:
For this sequence, we have that:
\(a_1 = \frac{1}{4} = 0.25, n = 8, q = -5\)
Hence, the sum is:
\(S = \frac{0.25(1 - (-5)^8)}{4} = -24414\)
Item B:
For this sequence, we have that:
\(a_1 = -\frac{1}{4} = -0.25, n = 12, q = 5\)
Hence, the sum is:
\(S = \frac{-0.25(1 - (5)^12)}{-4} = -15258789\)
Item C:
For this sequence, we have that:
\(a_1 = \frac{1}{5} = 0.2, n = 11, q = -4\)
Hence, the sum is:
\(S = \frac{0.2(1 - (-4)^11)}{3} = 279620.3\)
Item D:
For this sequence, we have that:
\(a_1 = -\frac{1}{5} = -0.2, n = 10, q = 4\)
Hence, the sum is:
\(S = \frac{-0.2(1 - (4)^10)}{-3} = -69905\)
Hence option D is correct.

a rectangle's length is 5cm more than its width, if it has an area of 336 cm squared find the length
The length of the rectangle is 19 cm.
The formula for the area of a rectangle,
Area = Length x Width
Given that the area is 336 cm squared.
So, we can set up an equation,
⇒ 336 = (w + 5)w
where w represents the width of the rectangle.
Expanding this equation,
⇒ 336 = w² + 5w
Moving all terms to one side:
⇒ w² + 5w - 336 = 0
This is a quadratic equation that we can solve using the quadratic formula,
⇒ w = (-5 ± √(5² - 4(1)(-336))) / (2(1))
⇒ w = (-5 ± 23) / 2
We'll take the positive value,
⇒ w = 14
So, the width of the rectangle is 14 cm.
We also know that the length is 5 cm more than the width,
Therefore,
⇒ l = w + 5
⇒ l = 14 + 5
⇒ l = 19
Therefore, the length of the rectangle is 19 cm.

Luego es lanzado en sentido contrario por el mismo plano con una velocidad inicial de 4.0 m/s. a) ¿Qué distancia subirá por el plano antes de detenerse? b) ¿Deslizará nuevamente hacia abajo?AYUDAAAA ES PARA HOY!!!
The distance travelled across the slant will be -
h = √({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}² and yes it will slide down again.
What is resolution of vectors?If we take a single vector we can find a pair of vectors at right angles to each other that would combine to give the single original vector. This reverse process is called resolution or resolving vectors.
Given is that body slides down a 22º inclined plane with constant speed. It is then thrown in the opposite direction by the same plane with an initial velocity of 4.0 m/s.
[A] -
We can write the total distance covered along the slant as a function of [x] and [y] components as -
h = h[x] i + h[y] j
Now -
h[x] = 4tcos(22°)
Now -
F = ma
F = m{dv/dt}
Fdt = mdv
mg sin(22°)dt = mdv
dt = {1/g sin(22°)}dv
∫dt = ∫ {1/g sin(22°)}dv
t = v/g sin(22°)
So, we can write -
h[x] = 4 cos(22°)v/g sin(22°)
h[x] = {4v/g}{cot (22°)}
Similarly -
h[y] = 4t'cos(22°)
F = ma
F = m{dv/dt}
Fdt = mdv
N cos(22°) - mg = F
{N cos(22°) - mg}dt' = mdv
{mg cos(22°) - mg}dt' = mdv
{g cos(22°) - g}dt' = dv
dt' = dv/{g cos(22°) - g}
∫dt' = ∫dv/{g cos(22°) - g}
t' = {v/g(cos(22°) - 1)}
So -
h[y] = 4 x {v/g(cos(22°) - 1)} x cos(22°)
h[y] = {4v/g(cos(22°) - 1)} cos(22°)
So -
Distance travelled across the slant -
h = √({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}²
[2] -
Yes, it will slide down again.
Therefore, the distance travelled across the slant will be -
h = √({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}² and yes it will slide down again.

A. They are congruent and similar
B. They are congruent but not similar
C. They are similar but not congruent
D. They are neither congruent nor similar
They are congruent but not similar is true about triangle M and N.
When a triangle is dilated with a scale factor 2, its side lengths are multiplied by 2 and its area is multiplied by 4.
When a triangle is reflected over the x-axis, its orientation is flipped, but its size and shape remain the same.
Since Triangle M is reflected over the x-axis, its orientation is flipped.
Then, it is dilated with a scale factor of 2.
Therefore, Triangle N is similar to Triangle M, but not congruent to it, because its size has been doubled.

The percentage that is less than the average number of shoppers in the original store at any time is 60%.
Little's law:Little's law is a fundamental principle in queueing theory that relates the average number of customers in a stable system to the average time that a customer spends in the system.
The law states that the average number of customers N in the system is equal to the average rate of customer arrivals r multiplied by the average time W that a customer spends in the system:
N = rWHere we have
For the new store, the owner estimates that, during business hours, an average of 90 shoppers per hour enter the store and each of them stays an average of 12 minutes.
=> Number of shoppers per minute = 1.5
=> Rate of shoppers per minute = 1.5
The manager estimates that each shopper stays in the store for an average of 12 minutes.
Hence, by Little’s law, the number of shoppers N = r × t
=> Number of shoppers = (1.5) × 12 = 18

please help me as soon as you can it would be greatly appreciated I’m in a hurry.
Answer:
a. 6.75 ft
b. Exponent on w is w^4
Step-by-step explanation:
a. The best thing here is to work with decimals
each piece was 3/4 foot tall which means each piece is 0.75 ft tall
Now since he staked 9, the height of the wood pile would be 9 * 0.75 = 6.75 ft
b. Firstly let’s evaluate the denominator
That becomes; 2v^-3w^8 * v^4w = 2v^(-3+4)w^(8+1) = 2vw^9
So let’s now divide this by the numerator
Since we are concerned with only the exponent on w, we place w^13 over w^9 = w^(13-9) = w^4
HELP!!!! The point P lies on the terminal side of the angle. Find the valueof the trigonometric function: P(-(5),5),cot (theta)
Answer:
A. 1
Explanation:
Given the point P(-5,5), this falls in the second quadrant.
Accoording to pythagoras theorem;
r^2 = x^2 +_ y^2
r^2 = (-5)^2 + 5^2
r^2 = 25 + 25
r^2 = 50
r = \sqrt[50]
r = 5\sqrt[5]
Get cot theta;
cot theta = 1/tan theta
in the second quadrant, tan theta = y/-x
tan theta = 5/-(-5)
tan theta = 5/5
tan theta = 1
Recall that cot theta = 1/tan theta
cot theta = 1/1
cot theta = 1

Steel rods are manufactured with a mean length of 30 centimeter (cm) Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.07 cm Click the icon to view a table of areas under the normal curve. (a) What proportion of rods has a length less than 29.9 cm? (Round to four decimal places as needed)
The proportion of rods with a length less than 29.9 cm is approximately 0.0764 (or 7.64%).
To find the proportion of rods that have a length less than 29.9 cm, we need to calculate the cumulative probability up to 29.9 cm using the normal distribution.
First, we need to calculate the z-score, which is a measure of how many standard deviations away from the mean a particular value is:
z = (x - μ) / σ
where x is the value we want to find the proportion for (29.9 cm in this case), μ is the mean (30 cm), and σ is the standard deviation (0.07 cm).
Plugging in the values, we get:
z = (29.9 - 30) / 0.07
= -0.1 / 0.07
≈ -1.4286
Next, we look up the cumulative probability corresponding to the z-score of -1.4286 in the standard normal distribution table. The table provides the area under the normal curve to the left of the given z-score.
From the standard normal distribution table, we find that the cumulative probability for a z-score of -1.4286 is approximately 0.0764.
Therefore, the proportion of rods with a length less than 29.9 cm is approximately 0.0764 (or 7.64%).
Note: The table of areas under the normal curve may be needed to obtain the precise value for the cumulative probability.

The correct answer is (a) event. An event is a subset of outcomes from the sample space. It represents a specific outcome or set of outcomes that we are interested in. Events can be simple, consisting of a single outcome, or they can be compound, consisting of multiple outcomes.
For example, consider rolling a fair six-sided die. The sample space is {1, 2, 3, 4, 5, 6}. Let's say we are interested in the event of rolling an even number. The event in this case would be {2, 4, 6}, which is a subset of the sample space.
Events can also be mutually exclusive, meaning they cannot occur at the same time, or they can be independent, meaning the occurrence of one event does not affect the probability of the other event occurring.
In summary, an event is a subset of outcomes from the sample space and represents a specific outcome or set of outcomes that we are interested in. It is an important concept in probability theory.

Step-by-step explanation:
A carpenter uses a hand saw to cut a piece of wood in half. The length of the saw blade is 40 cm, while the wood he is cutting is 8 cm across. Each time he extends the saw out with his arm, there is 5 cm of blade between the handle and the wood. When he pulls the saw toward his self with his arm, the saw handle is 25 centimetres from the wood. Each time he extends his arm out and pulls it back in, 1 second has passed. He starts with his arm extended out. Write an equation that models how far the tip of the saw is from the wood in terms of time.
Answer:
The equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17
Step-by-step explanation:
The given parameters are;
Length of the saw blade = 40 cm
Thickness of the wood across = 8 cm
Length of blade between wood saw handle with hand extended = 5 cm
Length of the tip from the wood at the above time = 40 - 8 - 5 = 27 cm
Length of blade between wood saw handle with saw pulled inwards = 25 cm
Length of the tip from the wood at the above time = 40 - 8 - 25 = 7 cm
Time for one complete cycle = 1 second
We note that the basic equation for oscillatory motion is of the form;
x(t) = A·cos(ωt) + d
Where:
A = Amplitude of the motion = (27 - 7)/2 = 10 cm
ω = Angular frequency = 2·π/T
ωt = Motion's phase
t = Time of the motion
d = The middle location = 27 - 10 = 17 cm
T = The time to complete a cycle = 1 s
Therefore;
ω = 2·π
Given that he stars with his arm extended out, we have;
27 = 10×cos(2×π×0) + 17
Therefore, the equation that models how far from the tip of the saw is from the wood in terms of time is x(t) = 10×cos(2×π×t) + 17.
