Suppose the government has a balanced budget and wants to increase spending without changing tax rates. The government enters the loanable funds market to borrow $150 billion for economic stimulus spending. How much money is available for private investment after this action has shifted the demand curve as shown in the figure?
The money available for private investment is $250 billion dollar
What is demand curve ?
The demand curve is a graphical representation of the connection between the cost of a commodity or service and the amount that is demanded over time. The price will often be shown on the left vertical axis in a representation, and the amount needed will typically be shown on the horizontal axis.
Refer to the attachment for graph:
Once investments and government borrowing are added together, the total is = $400
if borrowing from the government is= $150
private investment
=( investment and and government borrowing) - (government borrowing )
= $400 - $150 = $250

5=?
Answer:
5 = 1
or
5 = 25
Step-by-step explanation:
I've seen two answers to this.
1. Since we are told 1 = 5, then 5 = 1.
One answer is 1 = 5
2. Since each number on the right is 5 times the number on the left, then 25 corresponds to 5, and 5 = 25.
Answer: 5=1 (The correct answer) 5=25 (The answer that makes sense but is not correct).
Step-by-step explanation:
Explanation for answer 1: It say's that 1 = 5.
Explanation for answer 2: If we follow the pattern of adding 5 each time we go up a number then 5 would equal 25.

Answer:
The letter a in an ellipse equation is:
Half of the major axis if a > b and the ellipse is horizontal, orHalf of the minor axis if b > a and the ellipse is vertical.Step-by-step explanation:
General equation of an ellipse
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]
where:
center = (h, k)Vertices = (h±a, k) and (h, k±b)Foci = (h±c, k) or (h, k±c) where c²=a²−b²If a > b the ellipse is horizontal, a is the major radius, and b is the minor radius.
If b > a the ellipse is vertical, b is the major radius, and a is the minor radius.
The major axis is the longest diameter of an ellipse, so the major radius is one half of the major axis.
The minor axis is the shortest diameter of an ellipse, so the minor radius is one half of the minor axis.
Therefore the letter a in an ellipse equation is:
The major radius (half of the major axis) if a > b and the ellipse is horizontal, orThe minor radius (half of the minor axis) if b > a and the ellipse is vertical.Cp when Sp is 5625 and profit is 25%

One hundred eight Americans were surveyed to determine the number of hours they spend watching television each month. It was revealed that they watched an average of 151 hours each month with a standard deviation of 32 hours. Assume that the underlying population distribution is normal.
Which distribution should you use for this problem? (Enter your answer in the form z or tdf where df is the degrees of freedom.)
The Z distribution also referred to as the standard normal distribution is the distribution that we would have to use here.
What is the z distribution?A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution.
By transforming the values of any normal distribution into z-scores, it is possible to standardize it. Z-scores indicate the number of standard deviations from the mean that each value falls within.

What are linear equations?In mathematics, a linear equation is one that may be written in the form where the variables are alphabets, and the coefficients are frequently real integers. An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
It is rather simple to locate both intercepts when an equation is stated in this way (x and y).
The given linear equation is
6 - (3/4)x + (1/3) = (1/2)x + 5
In this equation the fractions are
(3/4), (1/3) and (1/2)
Take the LCM of 4, 3, and 2
LCM(4, 3, 2) = 12
So, if we multiply the equation with the number 12 we can eliminate the fractions.

y: 7,6,5,4,3
y=2x-3 x: -1, 0, 1, 2, 3
y: -5, -3, -1, 1, 3
By evaluating in x = 0, we can see that the function with the greater y-intercept is the first one:
y=-x+6
Which function has the greater y-intercept?
For any function y = f(x), we define the y-intercept as the value that y takes when we evaluate the function in x = 0.
For the first function:
y = -x + 6
The y-intercept is:
y = -0 + 6 = 6
While for the second function:
y = 2x - 3
Evaluating in 0 we get:
y = 2*0 - 3 = -3
So the y-intercept of the first function is 6, and the one of the second function is -3.
Then the first function has the greater y-intercept.

Timothy plans to add a railing parallel to a flight of stairs that goes down to the basement in his house. Each step has the dimensions shown in the sketch.
What will be the length of the railing?
The length of the railing is 105.81 inches.
Given,
The stair has 7 steps
The rise of each step = 8.5 inches
The tread of each step = 12.5 inches
Slope of each step = x
We have to find the length of the railing.
Length of railing = 7x
Then,
Slope of step, x can be determined using Pythagorean theorem.
Let rise be the height of the right angled triangle and tread be the base of the triangle
Then,
Hypotenuse= Slope, x = [tex]\sqrt{Rise^{2} + Tread^{2} }[/tex]
x = [tex]\sqrt{8.5^{2}+ 12.5^{2} }[/tex]
x = [tex]\sqrt{72.25 + 156.25}[/tex]
x = √228.5
x = 15.12 inches
That is,
The slope, x of one step is 15.12 inches
Now,
Length of the railing = 7x = 7 × 15.12 = 105.81 inches
Therefore,
The length of the railing is 105.81 inches.

A toy rocket is shot vertically into the air from a launching pad 7 feet above the ground with an initial velocity of 72 feet per second. The height $h$, in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=-16 t²+72 t+7. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at ? second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is ? feet.
(Simplify your answer.)
The time taken for the rocket to reach its maximum height is; 2.25 seconds.
The maximum height reached by the toy rocket is; 88 feet.
What is the maximum height reached by the rocket?It follows from the task content that the maximum height reached by the rocket is to be determined.
The given function is; h (t) = -16 t² + 72t + 7.
Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.
Therefore; at maximum height;
h'(t) = 0
h'(t) = -32t + 72 = 0
-32t = -72
t = -72/-32
t = 2.25 seconds.
Therefore, the time taken for the rocket to reach its maximum height is; 2.25 seconds.
Also, the maximum height reached by the rocket is at; h (2.25);
h(2.25) = -16(2.25)² + 72 (2.25) + 7

What is meant by a function?A function from a set X to a set Y in mathematics assigns to each element of X exactly one element of Y. The domain of the function is the set X, and the codomain of the function is the set Y.
The first known approximation to the concept of function is attributed to the Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Functions were originally idealistic representations of how one variable quantity depended on another. The location of a planet, for example, changes throughout time. Historically, the concept was formed with infinitesimal calculus near the end of the 17th century, and the functions that were analyzed were differentiable until the 19th century.
Given function,
f(x)=[tex]e^{2 x^{2} +5}[/tex]/-6x
f'(x)=-1/6x([tex]e^{2 x^{2} +5}[/tex])(4x)+[tex]e^{2 x^{2} +5}[/tex](1/6x²)

2x + ky = 14
For the given system of linear equations 6x-12y = -7 and 2x + ky = 14 the value of k for which linear equations are inconsistent is k= -4.
As given in the question,
Given system of linear equations are as follow:
6x-12y = -7 ____(1)
2x + ky = 14 _____(2)
Form equation (1) we have,
6x -12y = -7
⇒3 ( 2x -4y) = -7
⇒ 2x - 4y = -7 /3 ____(3)
From equation (2) and (3) we have,
2x + ky = 14
2x - 4y = - 7/3
Value of k so that the given system of equations are inconsistent is given by:
k = -4
For inconsistent there is no solution.
Therefore, for the given system of linear equations 6x-12y = -7 and 2x + ky = 14 the value of k for which linear equations are inconsistent is k= -4.

The graph of the linear equation can be seen in the image at the end.
Which graph represents the amount of money Anika has?We start by defining the variables we will use:
x = number of weeks.
y = money that Anika has.
We assume that Anika starts with $0, and then she wins $5 each week, so after x weeks she has:
y = $5*x
To graph this linear equation we need to find two points on the line, if x = 0 we get:
y = $5*0 = $0
So we have the point (0, 0)
if x = 1
y = $5*1 = $5
