with a reserve requirement of 5% and an initial deposit of $400, what is the maximum total amount of money that will be in the money supply? assume that all currency is deposited in a bank 7 banks hold no excess reserves (rr=.05)
Answers
The maximum money supply with a 5% reserve requirement and a $400 initial deposit is $8,000.
How to find maximum money?To calculate the maximum total amount of money that will be in the money supply, we need to consider the money multiplier effect based on the reserve requirement.
The money multiplier is given by the formula: MM = 1 / reserve requirement.
Given that the reserve requirement is 5% (rr = 0.05), the money multiplier is MM = 1 / 0.05 = 20.
The initial deposit is $400.
To calculate the maximum total amount of money in the money supply, we multiply the initial deposit by the money multiplier:
Maximum Money Supply = Initial Deposit * Money Multiplier
= $400 * 20
= $8,000.
Therefore, the maximum total amount of money that will be in the money supply is $8,000 when the reserve requirement is 5% and all currency is deposited in banks with no excess reserves.

1 m cube is equal to how many centimetre cube?
Answers
Answer:
1,000,000 cm³
Step-by-step explanation:
A cube has 3 dimensions of equal measure: length, width and height
To determine the volume of a cube, we multiply the dimensions:
⇒ volume of a cube = length × width × height
1 metre = 100 centimetres
Therefore, for a cube with a length, width and height of 100 cm:
⇒ volume = 100 cm × 100 cm × 100 cm

(For 160,000 it takes 18ms to sort each half. Then merging together the two sorted halves with 80,000 numbers in each of them takes 40-218 = 4 ms. For 320,000 elements, it will take 240 to sort each half and 24 to merge the sorted halves with 160,000 numbers in each, for the total of 240+8 = 88 ms.)
Answers
For a larger input size of 320,000 elements, it will take 240 ms to sort each half and 24 ms to merge the sorted halves, resulting in a total time of 264 ms.
The given information describes the time required for sorting and merging operations on two different input sizes. For 80,000 elements, it takes 18 ms to sort each half, resulting in a total of 36 ms for sorting. Merging the two sorted halves with 80,000 numbers in each takes 40 - 18 = 22 ms.
When the input size is doubled to 320,000 elements, the sorting time for each half increases to 240 ms, as it scales linearly with the input size. The merging time, however, remains constant at 4 ms since the size of the sorted halves being merged is the same.
Thus, the total time for sorting and merging 320,000 elements is the sum of the sorting time (240 ms) and the merging time (4 ms), resulting in a total of 264 ms.
Therefore, based on the given information, the total time required for sorting and merging 320,000 elements is 264 ms.

Answers
The total distance the ball travels from the baseball player´s bat to the bird is 32.9 ft
Calculating the total distance travelledFrom the question, we have the following parameters that can be used in our computation:
The figure
Start by calculating the distance (d1) from the baseball player to the ground using the following Pythagoras theorem
d1 = √(8² + 15²)
d1 = 17
Next, we calculate the distance from the ground to the bird using
d2 = 10/cos(51)
d2 = 15.9
Add these distances
d = 17 + 15.9

6. What is the measure of ZDAB?
Answers
Answer:
118 degrees
Step-by-step explanation:
To solve this, you need to know some things.
There are 180 degrees in a straight line, and 180 degrees in a triangle (or a few other polygons).
If there are 180 degrees in a triangle, we can subtract the given degrees to find the missing degree.
180- 85 - 33 = 62
We can subtract that from 180 again, because we want to find the angle of the other side of the straight line of DAC, which is called supplementary angles (when two angles add up to 180 degrees or a straight line).
180 - 62 = 118
DAB is 118.

What is a parabola?
A parabola is a plane curve that is mirror-symmetrical and roughly U-shaped in mathematics. It fits several seemingly disparate mathematical descriptions, all of which can be shown to define the same curves. A point and a line are two ways to describe a parabola.
That’s a parabola in the usual orientation. y=1 is the directrix. (f, k) is the focus. Squared distance, as usual, is the fundamental quantity.
If (x,y) is a point in the set, the squared distance to y=1 is (y−1)². The squared distance to (f, k).
(y - 1)²=(x - f)²+(y - k)²
Hence, we can say that the set of all points (x, y) is equidistant from the point (f, k) and the line x.

The value of KL in the right triangle JKL is determined as 5.34.
What is the value of KL?
To find the value of side length KL, we need to determine the value of opposite side of triangle JML.
Apply trigonometry identity as follows;
tan (51) = JL/JM
tan (51) = JL/14
JL = 14 x tan(51)
JL = 17.29
The value of KL is determined by considering right triangle JKL.

4 A home-decorating company is determining the amount of fabric required for a customer's window treatments. A single window requires 13 yards and a double 7 window requires 16, yards of fabric. If there are two single windows and one double window, how much fabric is required?
Answers
The solution will be that the home-decorating company will require 42 yards of fabric for the customer's window treatments.
As per the information we have received from the question,
A single window requires 13 yards and a double window requires 16 yards of fabric. We are asked to find out the length of fabric that will be required by the home-decorating company, in case there were 2 single windows and 1 double window. The total amount of fabric that will be required by the home-decorating company is hence equal to
13×(no of single windows)+ 16×(no of double windows)
Here, no of single windows= 2
And, no of double window= 1
Hence, total fabric length=13×2 + 16×1=26 + 16=42 yards
Hence the solution is 42 yards of fabric.

state and interpret the y-intercept, if applicable. if not applicable, explain why.
Answers
The y-intercept of a function is the point at which it intersects the y-axis. In other words, it is the value of the function when the input (x) is zero.
Whether or not a function has a y-intercept depends on its equation and the nature of the function. For example, a linear function of the form y = mx + b (where m is the slope and b is the y-intercept) will always have a y-intercept, since b represents the value of y when x = 0. On the other hand, some functions (such as circles or exponential functions) do not intersect the y-axis and therefore do not have a y-intercept.
If a function does have a y-intercept, its value can provide useful information about the behavior of the function. For example, in a linear function, the y-intercept represents the starting point of the line and can be used to calculate the value of the function at any point along the line. In a quadratic function, the y-intercept represents the point at which the parabola intersects the y-axis and can provide information about the maximum or minimum value of the function.
In summary, the y-intercept is an important concept in mathematics that can provide valuable information about the behavior of a function. However, it is not always applicable, depending on the equation and nature of the function in question.

∠1 and ∠2 are supplementary. m∠1=124°m∠2=(2x 4)° what is the value of x? select from the drop-down menu to correctly answer the question. x = choose...
Answers
For the two supplementary angles given, the value of x is 30. Two angles are called supplementary when their measures add up to 180 degrees.
If two angles are supplementary, their sum must equal 180 degrees. Supplementary angles are double of complementary angles. So if m∠1=124° and
m∠2=(2x - 4)°, we can set up the equation:
124 + (2x - 4) = 180
Solving for x, we can isolate x by subtracting 124 from both sides:
2x - 4 = 56
Adding 4 to both sides:
2x = 60
Finally, dividing both sides by 2:
x = 30
So the value of x is 30
