If jimmy as three balls and gives away one and if earl gives jimmy fifteen balls and jimmy loses seven. how many balls does he have?
Answer: Jimmy has 10 balls .
Step-by-step explanation:
Since we have given that
Number of balls Jimmy has = 3
Number of lost balls = 1
Remaining balls Jimmy has = 3-1=2
Number of balls Earl gives to Jimmy = 15
Now,
Total Number of balls Jimmy has = 15+2=17
Again,
Number of balls Jimmy lost = 7
So,
Remaining balls Jimmy has = 17-7=10
So, he has 10 balls at last .
Let f(x) = 2x2 − 2x + 7 and g(x) = x2 + 9x − 6. find f(x) − g(x). (1 point) x2 − 11x + 13 x2 − 11x + 1 x2 + 7x + 1 x2 + 7x + 13
Answer:
[tex]x^2-11x + 13[/tex]
Step-by-step explanation:
Let [tex]f(x) = 2x^2 - 2x + 7[/tex] and [tex]g(x) = x^2 + 9x - 6[/tex]
We need to find f(x)- g(x)
Replace f(x) and g(x). then subtract the expressions
[tex]f(x)-g(x) =(2x^2 - 2x + 7)- (x^2 + 9x - 6)[/tex]
Remove the parenthesis and multiply negative sign inside second parenthesis
[tex]2x^2 - 2x + 7- x^2 - 9x + 6[/tex]
Combine like terms
[tex]x^2-11x + 13[/tex]
what statement describes the function f(x)=|x^4-x^3|
did u ever get the answer for this
The given function f(x) = |[tex]x^{4}[/tex] - x³| is Option A. neither even nor odd because substituting -x changes the form of the function inside the absolute value. Thus, the function does not meet the criteria for either even or odd functions.
To determine if the function f(x) = |[tex]x^{4}[/tex] - x³| is even, odd, or neither, we need to check how it behaves under the transformation x -> -x.
An even function satisfies the property f(-x) = f(x) for all x, while an odd function satisfies f(-x) = -f(x) for all x.
First, let's consider the inside of the absolute value:
If we replace x with -x, we get: f(-x) = |[tex]-x^{4}[/tex] - (-x)³| = |[tex]x^{4}[/tex] + x³|.
We see that the expression has changed, since |[tex]x^{4}[/tex] - x³| is different from |[tex]x^{4}[/tex] + x³| . Therefore, f(x) does not exhibit the properties of being either even or odd.
This means the correct answer is:
Option A. The function is neither even nor odd.
Complete question:
Which statement describes the function f(x) = the absolute value of x^4 - x^3?

The length of a rectangle is 5 yd longer than its width. if the perimeter of the rectangle is 46 yd , find its area.
The area of the rectangle is 126 square yards.
Solving the area and perimeter of a rectangle.
The area of a rectangle is the multiplication of the length and the width. The perimeter of the rectangle is calculated by using the formula perimeter = 2(length × width).
Let the Length be (L) and the width be (w).
Length = w + 5Width = wPerimeter = 2 (length + width)
Perimeter = 2 ((w+5) +w)
Perimeter = 2w + 10 + 2w
Perimeter = 4w + 10
Since Perimeter = 46 yd, then:
46 = 4w + 10
4w = 36
w = 36/4
w = 9 yards
Length = 9 + 5 = 14 yards
The area of the rectangle is:
Area = length × width
Area = 14 yd × 9 yd
Area = 126 yd²

what is the equation for the linear model in the scatter plot obtained by choosing the two points closest to the line?
y= -3.5x+57.5
y= 3.5x+57.5
y= -3.5+32.5
y= -3x+57.5
Answer: The correct option is
(A) [tex]y=-3.5x+57.5.[/tex]
Step-by-step explanation: We are given to find the equation for the linear model in the scatter plot obtained by choosing the two points closest to the line.
From the table and the scatter plot sown in the figure, we note that
the two points that are closest to the line are (5, 40) and (15, 5).
We know that
the slope of a line passing through the points (a, b) and (c, d) is given by
[tex]m=\dfrac{d-b}{c-a}.[/tex]
So, the slope of the given line will be
[tex]m=\dfrac{5-40}{15-5}=-\dfrac{35}{10}=-3.5.[/tex]
Since the point (5, 40) is very close to the line, so its equation will be
[tex]y-40=m(x-5)\\\\\Rightarrow y-40=-3.5(x-5)\\\\\Rightarrow y=-3.5x+17.5+40\\\\\Rightarrow y=-3.5x+57.5.[/tex]
Thus, the required equation for the linear model is [tex]y=-3.5x+57.5.[/tex]

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 5050 states. what is the probability that she selects the route of fourfour specific capitals? is it practical to list all of the different possible routes in order to select the one that is best?
The probability of the presidential candidate selecting a specific route of four capitals is approximately 0.00575. It is not practical to list all the different possible routes to select the best one.
Explanation:To find the probability that the presidential candidate selects a specific route of four capitals, we need to calculate the number of possible routes and divide it by the total number of routes. Since there are 44 capitals and we need to select 4, we can use the combination formula.
The number of possible routes is given by C(44,4) which is equal to 44!/(4!(44-4)!) = 44!/(4!40!) = (44*43*42*41)/(4*3*2*1) = 91,390.
The total number of routes is 50P44, which is equal to 50!/6! = (50*49*48*47...*7*6!)/(6!) = (50*49*48*47...*7) = 15,890,700.
Therefore, the probability of selecting the specific route of four capitals is 91,390/15,890,700 = 0.00575 (rounded to 5 decimal places). This means that there is a very low probability of selecting this specific route.
It is not practical to list all of the different possible routes in order to select the best one, as there are over 15 million routes. Instead, the candidate may use other criteria such as population density, political demographics, or strategic considerations to determine the best route.

Connor and Megan are separated by 50-18,5=31,5 dollars. 7,75-5,5=2,25 $ is the difference between the two saves. To save the same amount, it will take them 14 weeks.
What exactly do you mean by an equation system?Simultaneous equations, or a system of equations, Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system).
The number of equations must match the number of unknowns for a system to have a singular solution.
What function does an equation system serve?When there are multiple unknowns and there is sufficient data to set up equations in those unknowns, systems of equations are utilized to solve applications.

Given six distinct pairs of gloves, 12 distinct gloves in all, how many ways are there to distribute two gloves to each of six sisters
a) if the two gloves someone receives might both be for the left hand or right hand.
b) if each sister gets one left and one right.
Soln:
a) So i thought about dissectng the problem first into finding the number of ways in which I could make pairs of gloves:
C(12, 2)
then I asked how many ways could the sets of gloves be assigned amongst the 6 sisters:
6!6!
and taking the product of this would give me the amount of ways this could occur:
= C(12,2) * 6!
then for part b)
using this same idea except:
C(6,1) C(6,1) for the left and right glove each .
the C(6,1)*C(6,1)*6!
Right way to think them through?
Why do astronomers say that the sun rotates once every 27 to 31 days, rather than give an exact number?
Astronomers provide a range for the Sun's rotation period due to differential rotation, with varying speeds at different latitudes.
This question demands basic understanding of planetaty motion i.e rotation and revolution in general and about motion of sun in particular
Astronomers say that the Sun rotates once every 27 to 31 days because of the phenomenon known as differential rotation. This means that the speed of rotation of the Sun varies based on its latitude.
The rotation period of the Sun is about 25 days at the equator, 28 days at latitude 40°, and 36 days at latitude 80°. Due to this variable rotation speed, astronomers provide a range rather than an exact number for the Sun's rotation period.

Does tis table represent a function ?
Answer: A function is so F(X) = Y where for every X exist only one Y, in this case you can see that F(3) = 4 and F(3) = 3, so the independent variable x = 3, has two solutions y.
So the solution is A, because a function cannot have two different y values for one x value.
