jenny believes that spending one hour studying for economics will increase her grade by 20 points. studying for a second hour will increase her grade by 10 points. she also believes that studying for an hour for history will increase her grade by 15 points, but spending a second hour will increase her grade by only 5 points. jenny has two hours to study. if jenny wants to maximize her scores, what should she do?
If Jenny studies one hour both for economics and history she can gain 10+15=25 points
What is meant by Increasing?Increasing: Growing larger or greater. Therefore, if the derivative of a function is positive, then the function is increasing. Let's consider our example of g(x) = x2. The derivative of g(x) = x2 is g'(x) = 2x. Since we are multiplying x by the positive number 2, it's easy to see that g ' is positive when x is positive and negative when x is negative.
Jenny will receive 15 points if she simply studies economics, which equates to 10 points in the first hour and 5 points in the second.
Jenny will earn 20 points if she exclusively studies history, which equates to 15 points in the first class and 5 points in the second.
Jenny should study economics for one hour, which will get her 10 points, and history for one hour, which will gain her 15 points, for a total of 25 points in the two hours
So we concluded that if Jenny studies one hour both for economics and history she can gain 10+15=25 points

Find the HCF of 200 and 240
Answer:
its 40
Step-by-step explanation:
200 and 240 have an HCF of 40.
Finding all common factors between two numbers and choosing the biggest one yields the highest common factor (HCF).
So, let's determine factors of 200
1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200 are all factors of 200.
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, and 240 they are all factors of 240.
now, we will select the highest common factors of 200 and 240.
the highest common factors of 200 and 240 is 40.
Hence, the HCF of 200 and 240 is 40.

1.if the m∠7 = 115° , find the measure of ∠2
Show your work
Answer: The measure of is 115°.
Step-by-step explanation:
Now, assuming those angles are supplementary, then
m<7 + m<2 + 180
Because, supplementary angles sum 180\°, due to their position on a straight angle.
We know by given that m<7 = 115 , replacing this value, we have
115 + m<2 + 180
m<2 = 180 - 115
m<2 + 65

Hi I have question on solving algebraic fractions. How would I find the LCD for this?
(x/x+1)+(x-1/4)=(11/12)
I tried multiplying the denominator by the opposites (x+1 and 4) to make them the same denominator and then add them and cross multiply, however, I never got the right answer
The value of x is either 2 or -7/3.
Given expression:-
(x/x+1)+((x-1)/4)=(11/12)
We have to find the value of x.
The LCM of (x + 1) and 4 is 4(x - 1).
We can write,
[4x + (x + 1)(x - 1)]/4(x + 1) = 11/12
[tex]\frac{4x+x^2-1}{4(x+1)}=\frac{11}{12}[/tex]
We can multiply 4 to the given equation, and get,
[tex]\frac{4x+x^2-1}{(x+1)}=\frac{11}{3}[/tex]
By cross multiplying, we can write,
[tex]12(4x+x^2-1)=11(4(x+1))[/tex]
12x + [tex]3x^2[/tex] -3 = 11x + 11
[tex]3x^2[/tex] + 12x - 11x -3-11 = 0
[tex]3x^2[/tex] + x-14 = 0
Using the middle-term split theorem, we can write,
[tex]3x^2[/tex] + 7x - 6x -14 = 0
x(3x + 7) - 2(3x + 7) = 0
(3x + 7)(x - 2) = 0
x = -7/3, 2.

What is a function?A relation between a collection of inputs and one output for each of those inputs is the definition of a function.
A function is a connection between inputs in which each input is associated with precisely one output.
To put it another way, a function is a relationship between inputs. Each function has both a domain and a codomain or range that it operates inside.
Generally, The progression towards
g(x) = f(x -h) +k
depicts a translation with k units added on top and h units added to the right.
Since you have h equal to 0 and k equal to -2, this means that the graph is moved 0 units to the right and 2 units in the opposite direction of up.
The graph of g may be found by shifting f's graph down by two units.

A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in. If the container holds 1096 cubic feet of shipped goods, what percent is empty?
As per the volume of a rectangular prism, it is found that 34.76% of the container is empty.
Volume of a rectangular prism
The volume of the rectangle prism is calculated by multiplying the length, breadth and height of the prism.
The formula for the volume of rectangle prism is
V = l x w x h
where
l represents the length
w represents the width
h represents the height
Given,
A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in.
Here we need to find if the container holds 1096 cubic feet of shipped goods, what percent is empty
According to the given question,
Let us consider the length is 30ft, Width is 8ft and Height is 7ft.
Here the value 3ft refers the depth.
That one is also multiplied with the volume.
Therefore, the volume of the container is
=> 8 x 7 x 30
=> 1680
Therefore, the volume of the container is 1680 cubic feet.
So, here we have to percentage of the empty space for that we have to find the difference of them and convert it into percentage,
=> 1680 - 1096
=> 584
The percent of empty space is,
=> x% of 1680 = 584
=> x% = 584/1680
=> x% = 0.3476
=> x = 34.76
Therefore, 34.76% of rectangular prism container is empty.

A=
B=
It can be written in the form is like ax+b/x^2-9
so we only need the A and B.
Please reply to this ASAP
Step-by-step explanation:
so, if I understand your text correctly, we need to bring
2 - (x+2)/(x-3) - (x-6)/(x+3)
into a form
(ax + b)/(x² - 9)
what we notice immediately is
(x+3)(x-3) = x² - 9
that makes sense, as we want to transform all terms into fractions with the same denominator.
and the necessary "criss-cross" multiplication leads to (x² -9) as denominator.
so, let's transform every term to a fraction with that denominator, and then we add or subtract them all up as per the original expression.
2 :
multiply by (x²-9)/(x²-9)
2(x²-9)/(x²-9) = (2x²-18)/(x²-9)
(x+2)/(x-3) :
multiply by (x+3)/(x+3)
(x+2)(x+3)/(x²-9) = (x²+3x+2x+6)/(x²-9) =
= (x²+5x+6)/(x²-9)
(x-6)/(x+3) :
multiply by (x-3)/(x-3)
(x-6)(x-3)/(x²-9) = (x²-3x-6x+18)/(x²-9) =
= (x²-9x+18)/(x²-9)
for the whole expression we get then
(2x²-18)/(x²-9) - (x²+5x+6)/(x²-9) - (x²-9x+18)/(x²-9) =
= (2x²-x²-x² -5x+9x -18-6-18)/(x²-9) =
= ( 0 + 4x - 42 )/(x²-9)
a = 4

An observational study is based on observations and analysis of different comparable situations. A survey is actually a method to study about things directly through personally involving into the situations.
Experiments are mostly used in situations which asks for a solution to certain issue. An experiment is implementing new measures first and then check if it works and get on conclusions about it. Such experiments leads to new inventions.
