Answer:

Point, line and plane

Step-by-step explanation:

Words are defined using other defined words or terms. However, these three terms are very difficult to find other words to describe. Without using other terms, we create circular definitions; thus these are called the "undefined terms" of geometry.

It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.

For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

Answer:

D square root of 10 over 5

Step-by-step explanation:

sec means \(\frac{1}{x}\), so if sec of theta is \(\frac{\sqrt{10} }{2}\) in this situation then you can set those equal to one another to get x.

x=\(\frac{\sqrt{10} }{5}\)

cos is just another way to say x so what you got for x is your answer

The secant of theta is equal to the square root of 10 over 2 comma what is, then the value of cos is square root of 10 over 5 .The correct option is d.

For a right angle triangle, secant of the angle formed by the sides opposite to hypotenuse is equal to the ratio of Hypotenuse and the base of triangle,

Given the value of sec of θ

secθ = sqrt (10)/2

Then cos θ = 1/secθ

Plug the value, we get

secθ=  sqrt  (10) / 5

Thus, the correct option is d.

The probability that at least one sensor detects the pollutant is 0.9.The probability that either only S1 or only S2 detects the pollutant is 0.5.The probability that S1 does not detect the pollutant, and S2 detects the pollutant is 0.2.The probability that S2 fails to detect the pollutant is 0.3.

The event "at least one sensor detects the pollutant" refers to the scenario where either S1 or S2 (or both) detect the excessive pollution. This can be visualized as the union of the two events: S1 detecting the pollutant (event A) and S2 detecting the pollutant (event B). The probability of event A is 0.7, the probability of event B is 0.8, and the probability of both events A and B occurring together is 0.6. By applying the principle of inclusion-exclusion, we can calculate the probability of the union as P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = 0.7 + 0.8 - 0.6 = 0.9.

The event "either only S1 or only S2 detects the pollutant" can be represented as the exclusive OR (XOR) of the two events: S1 detecting the pollutant without S2 detecting it (event A) and S2 detecting the pollutant without S1 detecting it (event B). Since the probabilities of events A and B are not explicitly given, we assume that they are equal. Let's denote this probability as p. Therefore, the probability of either event A or event B occurring is 2p. Given that the sum of probabilities of all possible outcomes is equal to 1, we have 2p + P(A ∩ B) = 1. We are also given that P(A ∩ B) = 0.6. Solving these equations simultaneously, we find that p = 0.2. Hence, the probability of the event "either only S1 or only S2 detects the pollutant" is 2p = 2 × 0.2 = 0.4.

The event "S1 does not detect, and S2 detects the pollutant" is the complement of S1 detecting the pollutant (event A) intersected with S2 detecting the pollutant (event B). The probability of event A is 1 - P(S1 detects) = 1 - 0.7 = 0.3. The probability of event B is P(S2 detects) = 0.8. The probability of both events A and B occurring together is given as P(A ∩ B) = 0.6. Therefore, the probability of the event "S1 does not detect, and S2 detects the pollutant" is P(A' ∩ B) = P(A ∩ B') = P(A) - P(A ∩ B) = 0.3 - 0.6 = 0.2.

The event "S2 fails to detect the pollutant" is the complement of S2 detecting the pollutant. Therefore, the probability of this event is 1 - P(S2 detects) = 1 - 0.8 = 0.2.

What is Normal Distribution?

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell-shaped curve represents the probability.  

How to use z-table?

Step 1: In the z-table, find the two-digit number on the left side corresponding to your z-score. (e.g 0.9 1.4, 2.2, 0.5, etc.)

Step 2:Then look up at the top of the z-table to find the remaining decimal point in the range of 0.00 to 0.09. (e.g. if you are looking for 0.95 then go for the 0.05 column)

Step 3:Finally, find the corresponding probability from the z-table at the intersection of step 1 and step 2. We want to find out the probability that what percentage of his times between pitches are longer than 31 seconds.

Here, In the given question: we have,

Mean=36 seconds

Standard deviation = 2.5 seconds

So,

For x>39

We want to find out the probability that what percentage of his times between pitches are longer than 39 seconds.

\(\begin{aligned}&P(X > 39)=1-P(X < 39) \\&P(X > 39)=1-P\left(Z < \frac{x-\mu}{F}\right) \\&P(X > 39)=1-P\left(Z < \frac{39-36}{2.5}\right) \\&P(X > 31)=1-P\left(Z < \frac{3}{2.5}\right) \\&P(X > 39)=1-P(Z < 1.2)\end{aligned}\)

The z-score corresponding to 1.2 is 0.8849

\(\begin{aligned}&P(X > 39)=1-0.8849 \\&P(X > 39)=0.1151 \\&P(X > 39)=11.51 \%\end{aligned}\)

Therefore, 11.51% of his times between pitches are longer than 39 seconds.

The required ordered pair represents the center of the new circle after the transformation is (-x,y). Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them.

Here,
If a circle is reflected across the y-axis, its center, which was originally located at (x, y), will move to a new location that is the same distance from the y-axis but on the opposite side. Since the y-coordinate does not change during a reflection across the y-axis, the y-coordinate of the new center will remain the same as the original, which is y.

However, the x-coordinate will be negated, since the reflection across the y-axis involves flipping points to the opposite side of the y-axis. Therefore, the center of the new circle will have the coordinates (-x, y).

So the answer is A) (-x, y).

A using the limit definition derivative of f(x) = 7x²2 + 4x using the limit definition is f'(x) = 14x + 4.

To find the derivative of the function f(x) = 7x²2 + 4x using the limit definition of the derivative, we need to evaluate the following limit:

f'(x) = lim(h→0) [f(x + h) - f(x)] / h

Let's start by substituting f(x) into the limit expression:

f'(x) = lim(h→0) [(7(x + h)²2 + 4(x + h)) - (7x²2 + 4x)] / h

Now, we expand and simplify the expression inside the limit:

f'(x) = lim(h→0) [(7(x²2 + 2xh + h²2) + 4(x + h)) - (7x²2 + 4x)] / h

f'(x) = lim(h→0) [7x²2 + 14xh + 7h²2 + 4x + 4h - 7x²2 - 4x] / h

Next, we can cancel out like terms:

f'(x) = lim(h→0) (14xh + 7h²2 + 4h) / h

Now, we can factor out an h from the numerator:

f'(x) = lim(h→0) h(14x + 7h + 4) / h

The h term cancels out:

f'(x) = lim(h→0) 14x + 7h + 4

Finally, we can evaluate the limit as h approaches 0:

f'(x) = 14x + 7(0) + 4

f'(x) = 14x + 4

Therefore, the derivative of f(x) = 7x²2 + 4x using the limit definition is f'(x) = 14x + 4.

The given statement " The allowable range for an objective function coefficient assumes that the original estimates for all the other coefficients are completely accurate so that this is the only one whose true value may differ from its original estimate " is false because the allowable range for an objective function coefficient assumes that the original estimates for other coefficients are approximately correct

The allowable range for an objective function coefficient assumes that the original estimates for all the other coefficients are approximately correct, but not necessarily completely accurate. The allowable range takes into account the potential variability or uncertainty in the estimated values of the other coefficients, as well as the impact of any errors or discrepancies in the data used to estimate the model.

Therefore, the allowable range provides a range of values within which the objective function coefficient can vary while still producing a valid and useful model. It does not assume that the other coefficients are completely accurate or that this is the only coefficient whose true value may differ from its original estimate.
