The question is asking for the value of h(g(1.5)) using given functions h(x) and g(x). First, find g(1.5) by substituting 1.5 into g(x) to get 3.5. Then, substitute 3.5 into h(x) to get the final answer of 12.
Explanation:Firstly, identify the functions h(x) and g(x) given to you. h(x) =
2x+5
and g(x)=
8-3x
. The question requires you to find h(g(1.5)). This means that you need to plug g(1.5) into h(x).
Start by calculating g(1.5). In the function g(x), replace x with 1.5. g(1.5) = 8 - 3*1.5 = 3.5.
Now, substitute the value obtained, which is 3.5, into h(x). So, h(g(1.5)) turns into h(3.5) = 2*3.5 + 5 = 12. Therefore, the value of h(g(1.5)) is
12

To calculate the composite function h(g(1.5)), first calculate the value of g(1.5) which is 3.5, then substitute this value into the function h(x) to get the answer, which is 12.
Explanation:The question is asking us to find the value of h(g(1.5)). This means we need to first find the value of g(1.5) and then substitute that value into the function h(x).
So, let's first determine g(1.5). We know that g(x)=8-3x. Substituting 1.5 in place of x in g(x), we get: g(1.5) = 8 - 3*(1.5) = 8 - 4.5 = 3.5.
Next, to find h(g(1.5)), we substitute the value of g(1.5) which is 3.5 into h(x) to get: h(3.5) = 2*(3.5) + 5 = 7 + 5 = 12. Thus, the value of h(g(1.5)) is 12.

A drawer contains 8 red shirts, 6 blue shirts, and 7 white shirts. If a shirt is drawn at random, what is the probability that the shirt will be blue?
Answer:
The Probability of drawing shirt is blue is [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
Given : A drawer contains 8 red shirts, 6 blue shirts, and 7 white shirts.
We have to find the probability if a shirt is drawn at random, then the shirt will be blue.
Total number of shirt in drawer = 8 + 6 + 7 = 21
Number of blue shirts = 6
Probability of an event = [tex]\dfrac{\text{number of possible outcomes}}{\text{number of total outcomes}}[/tex]
Event (E) : shirt drawn is blue.
number of possible outcomes = 6
number of total outcomes = 21
Thus, the Probability of drawing shirt is blue is [tex]\frac{6}{21}[/tex]
Simplifying , we get,
The Probability of drawing shirt is blue is [tex]\frac{2}{7}[/tex]

y =5.5x represents a proportional relationship. What is the constant proportionality?
Answer: 5.5 is the constant proportionality.
Step-by-step explanation:
Since we have given that
y = 5.5x
As we can see that
y is directly proportional to x.
So, mathematically written as
[tex]y\ \alpha\ x\\\\y=kx[/tex]
If we comparing both the expression, we get that
k = 5.5.
Hence, 5.5 is the constant proportionality.
The constant of proportionality of y = 5.5x is 5.5.
A directly proportional relational relationship can be represented below
y ∝ xwhere
∝ = symbol for proportionality
y and x are the variable that are related. Therefore,
y = kx
where
k = constant of proportionality.
The equations y = 5.5x can be modelled as directly proportional relationship using y = kx.
Therefore, k = 5.5 is the constant of proportionality.
The constant of proportionality of y = 5.5x is 5.5.

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.

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.
The dimensions of a closed rectangular box are measured as 50 centimeters, 90 centimeters, and 80 centimeters, respectively, with the error in each measurement at most .2 centimeters. Use differentials to estimate the maximum error in calculating the surface area of the box.
The maximum error in calculating the surface area of the box is approximately 176 square centimeters.
What is the surface area of the rectangular box?The surface area of the rectangular box is given by:
S = 2(wh + lh + lw)
where w, h, and l are the width, height, and length of the box, respectively. The differential of S with respect to each dimension can be expressed as:
dS = 2((h+dh)(w+dw) + (l+dl)(h+dh) + (l+dl)(w+dw)) + 2(wh + lh + lw) - 2S
where dw, dh, and dl represent the maximum error in each measurement, which is given as 0.2 cm. We have to find the maximum error in calculating the surface area, so we need to find the maximum value of dS.
Substituting the given values into the differential expression, we get:
dS = [2*(0.2)*80+2*90*(0.2)]+[2*(0.2)*50+2*80*(0.2)]+[2*(0.2)*50+2*90*(0.2)]
≈ 176

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.

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.

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.
