I've been crying about this question plz Help i'll give brainliest. Question 7
Step-by-step Answer/Explanation(answers are underlined and bolded):
okay, first you want to identify all the numbers and what they mean:
lawyers:235 (within the main number of lawyers: Criminal lawyers: 74)
Family doctors: 87
Sergeons: 30
From there, add up all of said numbers (ignore the Criminal lawyers for now):
235 + 87 + 30 = 352
(352 is going to be the denominator or the number that we are going to be dividing from.)
Next, we start answering the questions!
the first one is asking for the percent of sergeons.
To do this, we need to take the number of sergeons listed, 30, and divide 352 from it:
30/352 = .0852
then multiply this by 100:
.0852 x 100= 8.52%
So the percent of sergeons is 8.52%
Next question: the percent of Family Doctors
so like the last question, we identify the number of doctors, 87, and divide 352 from it, then multiplying it by 100 after:
87/352 = .2472
.2472 x 100 = 24.72%
Meaning the percent of family doctors is 24.72%
Criminal Law is next:
repeat the steps in the last couple of problems:
72/352 = .2045
.2045 x 100 = 20.45%
Family Law:
Okay, so now, we need to take that 235 from earlier and subtract it from 72 (the criminal law students) to get the number of students going into family law.
235 - 72 = 163
now repeat the steps from the earlier problems:
163/352 = .3864
.3864 x 100 = 38.64%
(I don't particularly understand what the rest is asking...I figure you can probably figure out from here...? I hope this helps!!)
Let f(x) = 5(3)x
The graph of f(x) is stretched vertically by a factor of 2 to form the graph of g(x).
Choose the equation of g(x).
Responses
g(x) = 10(3)xg(x) = 10(3)x
g(x) = 7(3)xg(x) = 7(3)x
g(x) = 2(3)xg(x) = 2(3)x
g(x) = 5(6)x
The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).
The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.
Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.
In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.
Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):
⇒ g(x) = 2 × 5(3)x = 10(3)x
Therefore, the required equation is g(x) = 10(3)x.

Let R be the relation defined on Z by aRb if a + b is even. Show that R is an
equivalence relation.
R s an equivalence relation on the set of integers Z using the properties of reflexivity, symmetry, and transitivity.
To show that the relation R defined on the set of integers Z is an equivalence relation, we need to demonstrate that it satisfies three properties: reflexivity, symmetry, and transitivity.
Reflexivity: For any integer a, a + a = 2a, which is always even. Therefore, aRa holds true for all integers a, showing that R is reflexive.
Symmetry: If aRb holds, then a + b is even. However, the sum of two integers is unaffected by their order. So if a + b is even, b + a will also be even. Hence, if aRb, then bRa, establishing symmetry.
Transitivity: Suppose aRb and bRc, meaning a + b and b + c are both even. In this case, we can express a + c as (a + b) + (b + c) - 2b. Since the sum of two even numbers is even, and 2b is also even, it follows that a + c is even. Therefore, if aRb and bRc, then aRc, demonstrating transitivity.
In conclusion, the relation R satisfies the properties of reflexivity, symmetry, and transitivity, proving that it is an equivalence relation on the set of integers Z.

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom. Here are the results:
A Venn Diagram has 2 overlapping groups: Bride, 17 and Groom, 20. The overlapping area shared by both Bride and Groom is 42. The area not included by any group is identified as 1. In this sample, are the events "bride" and "groom" mutually exclusive?
In this sample, the events "bride" and "groom" are not mutually exclusive.
In logic and probability theory, mutually exclusive events are events that do not take place at the same time. This means that any such two or more events are not going to happen together but will take place at different times. For example - when a die is rolled, we might get any of the six numbers but they don't appear at the same time together.
In the given problem we see that the randomly selected person can either be the groom's friend or the bride's friend or they can be a friend of both of them. This means that both events can take place together at the same time. And, hence, these are not mutually exclusive events.

Signature of the Principle investigator on the final proposal implies his responsibility for the following except
The signature of the Principal Investigator on the final proposal does not imply responsibility for the availability of funding or the financial aspects of the project.
The signature of the Principal Investigator (PI) on the final proposal does not imply responsibility for certain aspects of the project beyond their control or expertise. While the PI plays a crucial role in leading and overseeing the research project, there are certain areas for which they may not bear direct responsibility.One aspect the PI may not be responsible for is the availability of funding. Although they may have been involved in securing the initial funding or writing the budget proposal, the final decision and availability of funds typically lie with funding agencies, institutions, or sponsors. The PI's signature on the proposal signifies their commitment to the project but does not guarantee funding.Additionally, the PI may not be accountable for the technical or scientific success of every aspect of the project. Research projects often involve interdisciplinary collaborations and multiple team members who contribute their expertise. The PI's signature signifies their leadership and overall responsibility, but they rely on the expertise and contributions of other team members for specific tasks and outcomes.Furthermore, the PI may not bear sole responsibility for external factors that can impact the project, such as changes in regulations, unforeseen events, or external market conditions. While they may adapt the project's direction and approach as needed, these external factors are beyond their direct control.In summary, the signature of the Principal Investigator on the final proposal does not imply responsibility for funding availability, technical success of every aspect, or external factors that may influence the project.

What are the zeros of the function
Answer: i think c
Step-by-step explanation:
Solve the differential equation :
(2xy^2-x^3)dy+(y^3-2yx^2)dx=0
Multiply both sides by \(x^{-3}\) to get a homogeneous equation.
\((2xy^2 - x^3) \, dy + (y^3 - 2yx^2) \, dx = 0 \\\\ \implies \left(2\dfrac{y^2}{x^2} - 1\right) \, dy + \left(\dfrac{y^3}{x^3} - 2\dfrac yx\right) \, dx = 0\)
Substitute \(y=vx\) and \(dy = x\,dv + v\,dx\). This makes the equation separable.
\((2v^2 - 1) (x\,dv + v\,dx) + (v^3 - 2v) \, dx = 0\)
\(x (2v^2 - 1) \,dv + (2v^3 - v) \, dx + (v^3 - 2v) \, dx = 0\)
\(x (2v^2 - 1) \,dv + (3v^3 - 3v) \, dx = 0\)
Separate the variables.
\(x (2v^2 - 1) \, dv = (3v - 3v^3) \, dx\)
\(\dfrac{2v^2-1}{3v-3v^3} \, dv = \dfrac{dx}x\)
\(\dfrac13 \dfrac{1 - 2v^2}{v(v-1)(v+1)} \, dv = \dfrac{dx}x\)
Expand the left side into partial fractions.
\(\dfrac{1-2v^2}{v(v-1)(v+1)} = \dfrac av + \dfrac b{v-1} + \dfrac c{v+1} \\\\ \dfrac{1-2v^2}{v(v-1)(v+1)} = \dfrac{a(v^2-1) + bv(v+1) + cv(v-1)}{v(v-1)(v+1)} \\\\ 1-2v^2 = (a+b+c) v^2 + (b-c) v - a\)
Solve for the coefficients \(a,b,c\).
\(\begin{cases} a + b + c = -2 \\ b-c = 0 \\ -a = 1 \end{cases} \implies a=-1, b=c=-\dfrac12\)
Thus our equation becomes
\(\left(-\dfrac1{3v} - \dfrac1{6(v-1)} - \dfrac1{6(v+1)}\right) \, dv = \dfrac{dx}x\)
Integrate both sides.
\(\displaystyle \int \left(-\dfrac1{3v} - \dfrac1{6(v-1)} - \dfrac1{6(v+1)}\right) \, dv = \int \dfrac{dx}x\)
\(\displaystyle -\frac13 \ln|v| - \frac16 \ln|v-1| - \frac16 \ln|v+1| = \ln|x| + C\)
Solve for \(v\) (as much as you can, anyway).
\(\displaystyle -\frac16 \left(2\ln|v| + \ln|v-1| + \ln|v+1|\right) = \ln|x| + C\)
\(\displaystyle \ln\left|\frac1{\sqrt[6]{v^2(v^2-1)}}\right| = \ln|x| + C\)
\(\displaystyle \frac1{\sqrt[6]{v^4-v^2}} = Cx\)
\(\sqrt[6]{v^4-v^2} = \dfrac Cx\)
\(\left(\sqrt[6]{v^4-v^2}\right)^6 = \left(\dfrac Cx\right)^6\)
\(v^4-v^2 = \dfrac C{x^6}\)
Put the solution back in terms of \(y\).
\(\left(\dfrac yx\right)^4-\left(\dfrac yx\right)^2 = \dfrac C{x^6}\)
\(y^4 - x^2y^2 = \dfrac C{x^2}\)
\(\boxed{x^2y^4 - x^4y^2 = C}\)
which is about as simple as we can hope to get this.

an octagonal prism has a surface area of 50mm^2 and a volume of 88 mm^3 Another octagonal prism has a surface area of 450mm^2 and a volume of 792mm^3. Are these two shapes similar ? Explain your answer
The two octagonal prisms are similar because their corresponding sides are proportional.
How do we determine the octagonal prisms are similar?We can find out if two octagonal prisms are similar by checking if they have the same shape but may be different sizes. Two shapes are similar if their corresponding sides are proportional, and their corresponding angles are congruent.
Let's represent the dimensions of octagonal prism1:
Base edge length = a
Height = h
The octagonal prism2 dimensions:
Base edge length = b
Height = k
From the surface area and volume equations of an octagonal prism, we have the following system of equations:
50 = 2a² + 8ah
88 = 2a²h
450 = 2b² + 8bk
792 = 2b²k
We can simplify these equations by dividing the second equation by the first, and the fourth equation by the third, to eliminate h and k:
88/50 = 2a²h / (2a² + 8ah) => 44/25 = h / (a + 2h)
792/450 = 2b²k / (2b² + 8bk) => 44/25 = k / (b + 2k)
Then, we rearrange the equations to obtain expressions for h and k in terms of a and b, respectively:
h = (44/25) * (a + 2h)
k = (44/25) * (b + 2k)
Multiplying both sides of each equation by 25/19, we obtain:
h = (44/19) * a
k = (44/19) * b
We can now check if the corresponding sides are proportional:
Base edge length = a:b = 1:3
Height = h:k = 1:3
Since the corresponding sides are proportional, the two octagonal prisms are similar.

The domain of TSince T = {x ∈ R : 0 ≤ [x^2 − 25} ⇒ x² - 25 ≥ 0
⇒ x² ≥ 25
⇒ x ≥ ±5
⇒ -5 ≤ x ≤ 5.
Inverse image of f(x)
The inverse image of f(x) is f⁻¹(x) = ∛(x/3)
f : R → R defined by f(x) = 3x³
Let f(x) = y.
So, y = 3x³
Dividing through by 3, we have
y/3 = x³
Taking cube root of both sides, we have
x = ∛(y/3)
Replacing y with x we have
y = ∛(x/3)
Replacing y with f⁻¹(x), we have
So, the inverse image of f(x) is f⁻¹(x) = ∛(x/3)
Inverse image of g(x)
The inverse image of g(x) is \(g^{-1}(x) = e^{x}\)
g : R+ → R defined by g(x) = ln(x).
Let g(x) = y
y = ln(x)
Taking exponents of both sides, we have
\(e^{y} = e^{lnx} \\e^{y} = x\)
Replacing x with y, we have
\(y = e^{x}\)
Replacing y with g⁻¹(x), we have
So, the inverse image of g(x) is \(g^{-1}(x) = e^{x}\)
Inverse image of h(x)The inverse image of h(x) is h⁻¹(x) = x + 9
h : R → R defined by h(x) = x − 9
Let y = h(x)
y = x - 9
Adding 9 to both sides, we have
y + 9 = x
Replacing x with y, we have
x + 9 = y
Replacing y with h⁻¹(x), we have
So, the inverse image of h(x) is h⁻¹(x) = x + 9

write and simplify an expression to find the total cost of X pencils one poster board and one notebook
Answer:
xp + b + n
Step-by-step explanation:
Let "x" represent the amount of pencils needed to be bought
Let "p" represent the cost of 1 pencil
Let "b" represent the cost of one poster board
Let "n" represent the cost of one notebook
Since there is only one poster board and notebook being bought, they do not need a variable in front of their cost.
What should be subtracted from minus 3 / 4 so has to get 5 / 6 ?
Answer:
Step-by-step explanation:
Step 1:First Make 3/4 and 5/6 into like fractions.Find the L.C.M of 4 and
6,which is 12.
3*3/4*3=9/12
5*2/6*2=10/12
