If F(x)=integral of sqrt(t^3+1) dt from 0 to x, then F'(2)=?
F'(2) = 3
[tex]\int\limits^x_0 {\sqrt{t^3+1}} \, dt[/tex]
Using Fundamental Theorem of Calculus:
Since x = 2, you now have:
[tex]\int\limits^2_0 {\sqrt{t^3+1} } \, dt[/tex]
so F'(x) = [tex]\sqrt{t^3+1}[/tex]
--> F'(2) = [tex]\sqrt{2^3+1}[/tex] = [tex]\sqrt{9}[/tex] = 3
so F'(2) = 3
F'(2) is the square root of [tex](2^3+1)[/tex], which simplifies to 3.
Explanation:If F(x) is defined as the integral of [tex]\sqrt(t^3+1)[/tex] dt from 0 to x, then F'(x) represents the derivative of F with respect to x. According to the Fundamental Theorem of Calculus, the derivative of an integral function of this form is simply the value of the function inside the integral evaluated at x. Therefore, F'(2) is the square root of (2^3+1), which simplifies to sqrt(9), or 3.

Evaluate cos((Sin^-1)0)
To solve 'Evaluate cos((Sin^-1)0)', the arcsin of 0 is determined first, which equals 0 in degrees. Then, find the cosine of this resulting value, which equals 1.
Explanation:The student's question relates to an evaluation of trigonometric functions: 'Evaluate cos((Sin^-1)0)'. To solve this problem, it's important to recognize the meaning of inverse sine or arcsine. We can denote Sin^-1(0) as an angle, let's call it θ, whose sine value is 0. The sine of an angle will be 0 at 0 degrees. Therefore, Sin^-1(0) = 0 in degrees. Now we need to find out the cosine of this angle. Cosine of 0 degrees is 1, so cos(Sin^-1(0)) = cos(0) = 1. So, the answer is 1.

None of the above
Multiply the first equation by 2 and multiply the second equation by 3.
Final answer:
The best step to eliminate the x variable from the given system of equations is to multiply the first equation by –2 and the second by 3, facilitating the cancellation of the x terms and allowing for straightforward calculation of y.
Explanation:
To select the best possible first step to solving the system by first eliminating the x variable from the given equations 3x – 9y = 6 and 2x – 11y = 6, we need to make the coefficients of x in both equations equal in magnitude but opposite in sign. This way, when we add the equations together, the x terms will cancel out, leaving us with an equation in terms of y only. Here are the options analyzed:
Multiply the first equation by –2 and multiply the second equation by 3, resulting in –6x + 18y = –12 and 6x - 33y = 18. Adding these together will eliminate the x variable, which is the desired outcome.
Multiplying the first equation by –2 and the second equation by –3 does not effectively eliminate x because it gives us –6x + 18y = –12 and –6x + 33y = –18, which does not help in eliminating x when added or subtracted.
Multiplying the first equation by 2 and the second equation by 3 does not suit our needs for elimination as it results in 6x – 18y = 12 and 6x – 33y = 18, where adding or subtracting does not eliminate x.
Therefore, the correct first step is to multiply the first equation by –2 and multiply the second equation by 3. This approach aligns with standard algebraic methods for solving systems of equations by elimination, providing a clear and effective strategy to simplify the problem by removing one variable, allowing for the straightforward solution of the other.

The g subject of the equation x = 3g + 2 is g = (x - 2) / 3.
To make g the subject of the equation x = 3g + 2, you need to isolate g on one side of the equation. Here is a step-by-step guide:
Subtract 2 from both sides of the equation to get x - 2 = 3g.
Divide both sides of the equation by 3 to isolate g, resulting in g = (x - 2) / 3.
Now, g is the subject of the equation, and it can be expressed as g = (x - 2) / 3.

Here are the IQ scores of 10 randomly chosen fifth-grade students: 145,139,126,122,125,13,96,110,118,118. TRUE OR FALSE If the value 96 were removed from the data set, the IQR of the remaining 9 IQ scores would be lower than the IQR of all 10 scores.
False, because the IQR of 9 observations is 17 and the IQR of 10 observations is 13.
The given observations are 145, 139, 126, 122, 125, 113, 96, 110, 118, 118.
What is inter quartile range?The Interquartile Range (IQR) formula is a measure of the middle 50% of a data set. The smallest of all the measures of dispersion in statistics is called the Interquartile Range. The difference between the upper and lower quartile is known as the interquartile range.
Interquartile range = Upper Quartile - Lower Quartile
Q2=Q3 - Q1
Ascending order of the given observation is
96, 110, 113, 118, 118, 122, 125, 126, 139, 145
Here, Q1 (median of lower quartile) =113 and
Q3 (median of upper quartile) =126
Q2= 126-113
= 13
The value 96 were removed from the data set, so
110, 113, 118, 118, 122, 125, 126, 139, 145
Q1 =(113+118)/2 =115.5
Q3 =(126+139)/2
= 132.5
Q2 =132.5-115.5

Final answer:
The probability that a randomly chosen two-digit number from 10 to 99 is divisible by 5 is 1/5 or 20%.
Explanation:
To find the probability that a randomly chosen two-digit number from 10 to 99 is divisible by 5, we first establish the total number of two-digit numbers, which is 99 - 10 + 1 = 90. Numbers divisible by 5 end in either 0 or 5, so we can count how many of these there are within our range. Starting from 10, the first such number, we have 10, 15, 20, ..., 95. We clearly have two of such numbers per every 10 numbers, resulting in a total of 90/10 * 2 = 18 numbers divisible by 5 between 10 and 99. Hence, the probability is the number of favorable outcomes (numbers divisible by 5), divided by the total number of possible outcomes (two-digit numbers), which gives us a probability of 18/90 = 1/5 or 20%.

By decreasing each side of a rectangle by 1 unit, the area decreased from 60 square feet to 44 square feet. Find the perfect decrease in area. ...?
Answer:
Decrease in area would be 26.67%
Step-by-step explanation:
By decreasing each side of a rectangle by 1 unit area of the rectangle decreases from 60 square feet to 44 square feet.
So decrease in area = 60 - 44 = 16 square feet.
Percentage decrease in the area will be = [tex]\frac{\text{Decrease in area}}{\text{Area before decrease}}\times 100[/tex]
= [tex]\frac{16}{60}\times 100[/tex]
= [tex]\frac{160}{6}[/tex]
= 26.67%
Decrease in area would be 26.67%
The perfect decrease in area of the rectangle when each side is decreased by 1 unit, resulting in a decrease from 60 square feet to 44 square feet, is 16 square feet.
The question asks to calculate the perfect decrease in area of a rectangle when each side is decreased by 1 unit, resulting in a change in area from 60 square feet to 44 square feet. To solve for this, let's assign variables to the original dimensions of the rectangle. Let the length be L and the width be W.
The original area A1 is given by L imes W = 60. After reducing each dimension by 1, the new length and width are L - 1 and W - 1, respectively, so the new area A2 is (L - 1) imes (W - 1) = 44. The perfect decrease in area is the difference between the original and new areas, which is 60 - 44 = 16 square feet.
Using the completing-the-square method, find the vertex of the function f(x) =- 3x2 + 6x − 2 and indicate whether it is a minimum or a maximum and at what point.
To find the vertex of the quadratic function using the completing-the-square method, rearrange the equation in vertex form, complete the square, and simplify. The vertex of the given function is located at (1, 1) and represents a maximum point.
Explanation:To find the vertex of the function f(x) = -3x^2 + 6x - 2 using the completing-the-square method, follow these steps:
Start by rearranging the equation in the form f(x) = a(x - h)^2 + k, where (h, k) represents the coordinates of the vertex.Factor out the coefficient of x^2. In this case, factor out -3: f(x) = -3(x^2 - 2x) - 2.Complete the square by adding and subtracting the square of half the coefficient of x. In this case, add and subtract (2/2)^2 = 1: f(x) = -3(x^2 - 2x + 1 - 1) - 2.Simplify: f(x) = -3((x - 1)^2 - 1) - 2.Expand and simplify: f(x) = -3(x - 1)^2 + 3 - 2.Final vertex form: f(x) = -3(x - 1)^2 + 1.The vertex of the function is at the point (1, 1). Since the coefficient of x^2 is negative, the vertex represents a maximum point. Therefore, the vertex is a maximum point located at (1, 1).

Following the 1966 supreme court decision in miranda v. arizona, police began informing people placed under arrest that they "have the right to remain silent." what basic freedom is this meant to protect, and how does it affect arrested individuals?
Answer:
The protection against self-incrimination; it informs them that speaking to law enforcement could incriminate them.
Step-by-step explanation:
In the Supreme Court case Miranda v. Arizona, the court examined the rights protected in the
Fifth and Sixth Amendments to the U.S. Constitution. Ernesto Miranda was arrested after a
crime victim identified him in a police lineup. The police officers questioning him did not inform
him of his Fifth Amendment right that prevents government from forcing citizens to give
evidence against themselves. He also was not informed of his Sixth Amendment right to the
assistance of an attorney. In 1966, the Supreme Court agreed to hear the case and ruled in favor
of Miranda. As a result, police officers now read the Miranda warning to suspects before they are
arrested. This helps ensure suspects understand they have the right to not answer questions, or
say anything at all, if they choose. However, if a suspect chooses to speak despite the Miranda
warning, what they say could be used in court. The Miranda warning also explains that suspects
have the right speak to an attorney.
