Answer:
96.2+240.5/x
Step-by-step explanation:
g(x)=96.2(4)(x+2.5)
h(x)=[96.2(x+2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x)=(96.2x+240.5)(4)
h(x)=x(96.2+240.5/x)(4)----------bring out X,So 96.2x+240.5 is divided by x
h(x)=(96.2+240.5/x)(4)x
h(x)=a(4)x
so a=96.2+240.5/x
The value of a is 96.2 + 240.5/x.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
Given g(x) = 96.2(4)(x+2.5),
and h(x) = a(4)x,
to find a
h(x) = [96.2(x + 2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x) = (96.2x + 240.5)(4)
h(x) = x(96.2 + 240.5/x)(4)--------bring out x,So 96.2x+240.5 is divided by x
h(x) = (96.2 + 240.5/x)(4)x
h(x) = a(4)x
so a = 96.2 + 240.5/x
Hence value of a = 96.2 + 240.5/x

Answer:
question is incomplete. A complete question is ----> Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/16 of a liter of paint. find the number of statues.
each statue requires 1/16th of a liter of paint.
so, in a liter , 16th statues can be painted by Diana.
but A/C to question,
she has 7/8 of a liter of paint remaining.
so, we have to find how many statues she can paint in 7/8 litres.
so, number of statues = 7/8 × 16 = 14

Find the value of k for which the quadratic equation 4x2+kx+3=0 has equal roots.
Answer:
k = +/-√48
Step-by-step explanation:
4x^2 + kx + 3 = 0
For equal (duplicate) roots the discriminant = 0, so
k^2 - 4*4*3 = 0
k^2 - 48 = 0
k^2 = 48
k = +/-√48

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer: The total percentage decrease in the investor's stock account is 34%
Step-by-step explanation:
The investor's stock in Company A= $3800
The investor's stock in Company B= $3400
Percentage decline in stock of company A= 22%
Decline in value of stock of company A= 3800× 22/100
= 38×22
= $836
Percentage decline in stock of company B= 3400×12/100
= 34×12
=$408
Total decline in wealth of investor= 836+ 408
= $1244
Total percentage decline in wealth= 1244×100/7200
= 124400/7200
= 17.27%
The percentage decrease in investor's stock is 17.27%

Answer:
Sharon is wrong in step 2.
Step-by-step explanation:
So, basically we need to look at how Sharon step by step solved this problem.
We need to check her work by solving it ourselves, and seeing what she did wrong.
So we have:
9=-3(e-2)
The first thing that we need to do is distrubute the -3 to the e and -2:
9=-3e+6
This is looks like step 1 of Sharon's work.
Now, we need to get -3e alone by getting all the numbers to one side. This means we need to get rid of the 6 by subtracting 6 from both sides:
3=-3e
This doesnt look like what Sharon got.
She has:
15=3w
How did she do this? Note everything from here to the next bolded words explains her incorrect method of solving.
Well, what if we factor out a negative sign, making -3e into 3e?
This would make +6 into -5.
Then you would get:
9=-(3e-6)
The reason why you CANNOT do this is one problem.
Anything that has been factored(basically a value that has had something taken from it), such as the - in our case, cannot be subtracted or added to another number.
The reason you cannot subtract or add a factored number is it changes the value of the answer. So pretty much subtracting and adding factored numbers is BIG NO NO.
Back to how we solve for e.
So we have already gotten to step 2 with:
3=-3e
Lets get e alone by dividing both sides by -3.
3/-3=-1.
-3e/-3 = e.
So our answer, in step 3 is:
-1=e
This is not needed for your answer, and only shows how you can double check your answer.
So if oyu arent 100% sure with this, lets double check.
We got -1 as e, so lets plug it into our orginal equation:
9=-3(e-2)
Plug in -1:
9=-3(-1-2)
Distrubute the -3:
9=3+6
Add together the numbers:
9=9
This is correct!
Hope this helps!

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n?
06
18
30
0 36
Answer:
n = 30
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 180 when x = n, then
180 = kn ( divide both sides by n )
k = \(\frac{180}{n}\)
y = \(\frac{180}{n}\) x ← equation of variation
y = n when x = 5, thus
n = \(\frac{180}{n}\) × 5 = \(\frac{900}{n}\) ( multiply both sides by n )
n² = 900 ( take the square root of both sides )
n = \(\sqrt{900}\) = 30
The required value of y varies directly as x, so the value of 'n' is 30. Option c is correct.
What is proportionality?Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other. This relationship can be either direct or inverse, depending on whether the values increase or decrease together, or one value increases while the other decreases.
Here,
We can use the formula for direct variation which states that y = kx, where k is the constant of proportionality.
First, we can find the value of k by using the given values:
y = kx
180 = kn
n = 180/k
y = kx
n = 5
n = 5k
Now we can substitute n = 180/k into the second equation to solve for k:
n = 5k
180/k = 5k
180 = 5k²
k² = 36
k = 6 or k = -6
We can discard the negative value of k since we are dealing with a direct variation (where k is always positive).
So, k = 6, and we can use this to find the value of n:
n = 180/k = 180/6 = 30
Therefore, the value of n is 30.
