What is the domain of the function graphed below?
Answer:
x≤7
Step-by-step explanation:
i hope it will help
===============================================
Explanation:
The drawing is fairly faint, but it appears there's an arrow pointing to the left at the location (-6,3). If this is the case, then the function curve continues on forever in that direction.
The domain is the set of allowed x values. If we were to place the pencil on the blue curve and shade the x axis directly above or below that pencil point, then we would effectively shade everything to the left of x = 7.
In other words, we would shade x < 7 on the number line. The value x = 7 itself is left out due to the open hole.
Again, this all assumes that there is an arrow at (-6,3) that points to the left.
Container a was filled with water to the brim. then, some of the water was poured into an empty container b until the height of the water in both containers was the same. find the new height in both water containers
After pouring some water from container A into container B, the new height of the water in both containers will be equal.
When container A is filled with water to the brim, it reaches its maximum capacity. Let's assume the initial height of the water in container A is h.
When some water is poured from container A into container B, the water level in both containers will gradually equalize until they reach the same height. Let's denote this new height as H.
The reason the water levels equalize is due to the principle of fluid equilibrium. When the containers are connected and the water is allowed to flow, the water seeks a common level. This occurs because the pressure at the same height in a fluid is equal.
Therefore, after pouring water from container A to container B, the final height of the water in both containers will be H, which indicates that the water has reached an equilibrium point where the pressure is equal in both containers.

Find the absolute maximum and absolute minimum values of f on the given interval. f(t) = 7t + 7 cot(t/2), [pi/4, 7pi/4] absolute minimum value absolute maximum value
The absolute minimum value of given trigonometric-function is 331.9 and absolute maximum value of the same function is 4403.
What is absolute value?
The non-negative value of x or its distance from zero on the number line, regardless of its sign, is the absolute value, modulus, or magnitude denoted by | x | for any real number x. When a function reaches its absolute minimum value, it has reached its lowest conceivable value, and when it reaches its absolute maximum value, it has reached its highest possible value.
Given that the trigonometric function is f(t) = 7t + \(7 cot\frac{t}{2}\)
Also given the point at which the function has critical values= [\(\frac{\pi }{4} , \frac{7\pi }{2}\) ]
Value of function at \(\frac{\pi }{4}\) :
f( \(\frac{\pi }{4}\) ) = 7( \(\frac{\pi }{4}\) ) + 7 cot(\(\frac{\pi }{4}.\frac{1}{2}\))
=\(\frac{7\pi }{4}\) + 7 cot (\(\frac{\pi }{8}\))
=315 + 7 cot 22.5
=315 + 7(2.414)
= 315 + 16.898
=331.898
f( \(\frac{\pi }{4}\) ) ≈ 331.9
Value of function at \(\frac{7\pi }{2}\) :
f( \(\frac{7\pi }{2}\) ) = 7( \(\frac{7\pi }{2}\) ) + 7 cot(\(\frac{7\pi }{2}.\frac{1}{2}\))
=\(\frac{49\pi }{2}\) + 7 cot (\(\frac{7\pi }{4}\))
=4410 + 7 cot 315
=4410 + 7(-1)
=4410-7
=4403
f( \(\frac{7\pi }{2}\) ) =4403
The minimum value=331.9 & maximum value is 4403

Simplify each expression.
-15+(-23)
The expression -15 + (-23) simplifies to -38.
To simplify -15 + (-23), we can combine the negative numbers together. The negative sign in front of the 23 indicates that the number is being subtracted. Therefore, -15 + (-23) can be rewritten as -15 - 23.
To perform the subtraction, we start with -15 and subtract 23. Since we are subtracting a larger number from a smaller number, the result will be negative. Subtracting 23 from 15 gives us 8, and since we are subtracting, the answer is -8.
Therefore, -15 + (-23) simplifies to -38. The negative sign indicates that the result is a negative number.

→ Find EBG
75.4
→ Now find x
x + 75.4 + 44.2 = 180
→ Simplify
x = 60.4°
Answer:
x = 60.4°
Step-by-step explanation:
DEF is a straight line , then
110.2 + ∠ BEG + 25.6° = 180°
∠ BEG + 135.8° = 180° ( subtract 135.8° from both sides )
∠ BEG = 44.2°
∠ DEB and ∠ CBE are alternate angles and are congruent , so
∠ EBG = 110.2° - 34.8° = 75.4°
Then using °°the sum of angles in a triangle = 180°
x = 180° - 44.2° - 75.4° = 180° - 119.6° = 60.4°

El producto de los dos términos de una fracción es 162, hallar la fracción, si es equivalente a
If the product of the terms of the fraction is 162 and the fraction is equivalent to 2/9 then the fraction is 6/27.
Let's assume the two terms of the fraction are x and y. We are given that xy = 162. Also, we know that the fraction is equivalent to 2/9. So, we can write,
x/y = 2/9
Cross-multiplying, we get,
9x = 2y
Solving for y, we get,
y = (9/2)x
Substituting this value of y in the equation xy = 162, we get,
x(9/2)x = 162
Simplifying, we get,
(9/2)x² = 162
x² = 36
x = 6 (taking the positive square root as x and y are positive)
Substituting this value of x in the equation y = (9/2)x, we get,
y = (9/2)(6) = 27
So, the fraction is 6/27, which simplifies to 2/9.

the water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day. they would like the estimate to have a maximum error of 0.15 gallons. a previous study found that for an average family the variance is 3.61 gallons and the mean is 17.3 gallons per day. if they are using a 90% level of confidence, how large of a sample is required to estimate the mean usage of water? round your answer up to the next integer.
We need to round up to the nearest integer, the required sample size is 76 households.
To estimate the required sample size, we can use the formula:
\(n = (z^2 * s^2) / E^2\)
Where:
z is the z-score corresponding to the confidence level (90% = 1.645)
s is the standard deviation of the population (square root of the variance, so s = sqrt(3.61) = 1.898)
E is the maximum error allowed (0.15 gallons)
Plugging in the values, we get:
\(n = (1.645^2 * 1.898^2) / 0.15^2\)
n = 75.57
Since we need to round up to the nearest integer, the required sample size is 76 households.

The Graduate Record Examinations (GRES) are widely used to help predict the performance of applicants to graduate schools.
The scores on the GRE Chemistry test are approximately normal with mean 694 and standard deviation 112.
(a) About what percent of test takers earn a score less than 500 on the GRE Chemistry test?
(b) What proportion of test takers earn a score greater than or equal to 900 on this test?
(c) Estimate the score at the 99th percentile on the GRE Chemistry test.
a) About 4.16% of test takers earn a score less than 500 on the GRE Chemistry test.
b) About 96.64% of test takers earn a score greater than or equal to 900 on the GRE Chemistry test.
c) The estimated score at the 99th percentile on the GRE Chemistry test is approximately 954.512.
To answer these questions, we'll use the properties of the normal distribution and the given mean and standard deviation.
(a) To find the percentage of test takers who earn a score less than 500 on the GRE Chemistry test, we need to calculate the cumulative probability up to the score 500.
z-score = (X - mean) / standard deviation
where X is the score we are interested in.
z-score = (500 - 694) / 112
z-score ≈ -1.732
Now, we look up the cumulative probability for a z-score of -1.732 in the standard normal distribution table or use a calculator to find that the cumulative probability is approximately 0.0416 or 4.16%.
So, about 4.16% of test takers earn a score less than 500 on the GRE Chemistry test.
(b) To find the proportion of test takers who earn a score greater than or equal to 900, we need to calculate the cumulative probability from 900 to positive infinity.
z-score = (X - mean) / standard deviation
where X is the score we are interested in.
z-score = (900 - 694) / 112
z-score ≈ 1.839
Now, we look up the cumulative probability for a z-score of 1.839 in the standard normal distribution table or use a calculator to find that the cumulative probability is approximately 0.9664 or 96.64%.
So, about 96.64% of test takers earn a score greater than or equal to 900 on the GRE Chemistry test.
(c) To estimate the score at the 99th percentile on the GRE Chemistry test, we need to find the value that separates the lowest 99% of the scores from the highest 1%.
We use the z-score formula to find the z-score corresponding to the 99th percentile:
z-score = invNorm(0.99)
z-score ≈ 2.326
Now, we use the z-score to find the score corresponding to the 99th percentile:
X = mean + (z-score * standard deviation)
X = 694 + (2.326 * 112)
X ≈ 694 + 260.512
X ≈ 954.512
So, the estimated score at the 99th percentile on the GRE Chemistry test is approximately 954.512.
