The first four terms of the binomial series are 1, x³/5, (12/25)x⁶ and respectively.
The binomial provided to us is (1+x^3)^-1/5.
To find out the first four terms of the binomial, we shall first extend the standard binomial (1+x)^n.
[tex](1+x)^n = 1 + nx + [n(n - 1)/2!] x^{2} + [n(n - 1)(n - 2)/3!] x^{3} +...[/tex]
As we can see here,
The value of x = x³,
The value of n = -1/5.
We get,
[tex](1+x^{3})^{-\frac{1}{5} } = 1 - \frac{1}{5} (x^{3} ) + [\frac{-1}{5} (\frac{-1}{5} -1)/2!]x^{6} + [\frac{-1}{5} (\frac{-1}{5} -1)(\frac{-1}{5} -2)/3!]x^{27} +[/tex]
From the expansion, we can see,
First term = 1
Second term = x³/5
Third term = (12/25)x⁶
Fourth term = (-13/125)x²⁷

Which linear function has the same slope as the one that is represented by the table?
y = -1/5x +1/2 linear function has the same slope .
What is slope ?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. We shall comprehend the slope-finding method and its applications in this essay.
First solve for the slope

suppose you are35 years old and would like to retire at age65 . Furthermore, you would like to have a retirement fund from which you can draw an income of $150000 per yearforever! How much would you need to deposit each month to do this? Assume a constant APR of8 % and that the compounding and payment periods are the same.
Answer:
$1258.09
Step-by-step explanation:
You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.
Account balanceIn order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.
I = Prt
150,000 = P(0.08)(1)
P = 150,000/0.08 = 1,875,000
Annuity paymentThe value of an ordinary annuity is given by the formula ...
A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.
Using the values we know, we can find P:
1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P
P ≈ 1258.09
You would need to deposit $1258.09 each month.

How to find the equation for the linear function?The linear function is f(x)
f(-2) = - 2 and f(5) = 0
Therefore, let's find the equation for the linear function f(x):
A linear function is a function that represents a straight line on the coordinate plane.

Describe the transformation that shows Figure A is similar to Figure B
Dilate figure A with center o and scale factor 2
What is transformation?
The transformation, or f: X → X, is the name given to a function, f, that maps to itself. The pre-image X becomes the picture X following the transformation. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point.
Example: A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.
We know that re-sizing an item uses a transition called dilation.
In the figure the dimensions of the figures differ by a factor of 2.
Thus, dilation of figure A by a factor of 2 shows figure A is similar to Figure B

the first part of the ratio it asks is the "time spent studying in math" in hours which is 6.5

We use ratios to compare two numeric quantities or quantities with the same units
Basically a ratio of one quantity x to another quantity y can be expressed in the following ways, all read as the ratio of x to y
x/ y
x to y
x : y
The most useful way of representing a ratio is by using the fractional form because it can be used in determining other quantities
In this problem you spend 6.5 hours/week studying for math and 1.5 hours/week studying for English
Since both units are the same (hours/week) we can compute the ratio as
[tex]{\dfrac{\text{Number of hours studying math}}{\text{Number of hours studying English}}\\\\= \dfrac{6.5}{1.5}\\\\[/tex]
We can simply this fraction as follows
Multiply both numerator and denominator by 10
[tex]= \dfrac{65}{15}\\\\[/tex]
Divide both sides by 5
[tex]\dfrac{65 \div 5}{15 \div 5}\\\\= \boxed{\bold{\dfrac{13}{3}\\\\}}[/tex]
This is the same as 13:3 or 13 to 3
(Be careful what is the numerator and what is the denominator.
If the question had asked for the ratio of hours studying English to hours studying Math then the ratio would be 1.5/65 = 15/65 = 3/13)

Given: P is a point on the perpendicular bisector, l, of MN.
Prove: PM = PN
Line l is a perpendicular bisector of line segment M N. It intersects line segment M N at point Q. Line l also contains point P.
Because of the unique line postulate, we can draw unique line segment PM. Using the definition of reflection, PM can be reflected over line l. By the definition of reflection, point P is the image of itself and point N is the image of ________. Because reflections preserve length, PM = PN.
Given that P is a point on the perpendicular bisector, l, of MN, we have proved that PM = PN because By the definition of reflection, point P is the image of itself and point N is the image of N.
How to Interpret the Perpendicular Bisector?We are given :
P is a point on the perpendicular bisector, l, of MN.
Now, we want to prove that PM = PN
A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .
By the definition of reflection, we can deduce that point P is the image of itself , and point N is the image of M .
The line l acts as a Line of symmetry or axis of reflection.

You want to fence off a rectangular area of yard using the back side of your house as one of the sides. You have a total of 150 yards of fence. If the area of the fenced in portion comes to 2,800 square yards, what are the dimensions of the fenced-in area? Show all work for full credit.
The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .
In the question ,
it is given that
the total length of the fence = 150 yards
let L be the length of the area to be fenced
let B be the width of the house
Given that one side of the area is fenced using the back side of the house
So, the perimeter of the area to be fenced is 2L+B
equating both the perimeter we get
2L+B=150
B=150-2L ....(i)
Given the area fenced-in portion = 2800 yards
also the fenced-in portion area = L×B
hence
L*B=2800
Substituting the values of B from equation(i) , we get
L*(150-2L)=2800
150L - 2L² = 2800
2L² - 150L + 2800 = 0
simplifying further , we get
L² - 75L + 1400 = 0
L² -40L -35L +1400 = 0
L(L-40) -35(L-40) = 0
(L-35)(L-40) = 0
So , L = 35 yards or L = 40 yards
Using L = 35 yards , we get B = 150-2(35) = 80 yards
and using L =40 yards , we get B = 150-2(40) = 70 yards .
Therefore , The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .

(Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation.)
b) The equation of the line in standard form is
(Type your answer in standard form.)
The equation of the line passing through points (-2, 5) can be written as follows
slope intercept form: y = -x/3 + 13/3standard form: x + 3y = 13How to write the equation of the line in slope-intercept formEquation of a straight line is an equation of the form y = mx + c, where
m = slopec = interceptThe slope is the gradient which is the ratio of the difference in the y direction to the difference in x direction.
given that the equation of the line is x + 3y = 7
rewriting the equation gives
y = -x/3 + 7/3
hence the slope is -1/3, and this is equated with the formula for slope
[tex]\frac{y-y_{1} }{x-x_{1} }=-\frac{1}{3}[/tex]
substituting the values for points (-2,5) and cross multiplying gives
3 (y - 5) = - ( x - -2)
y - 5 = - (x + 2 ) /3
y - 5 = -x/3 - 2/3
y = -x/3 - 2/3 + 5
y = -x/3 + 13/3
Rewriting the equation of the line in standard form is done as follows
y = -x/3 + 13/3
3y = -x + 13
x + 3y = 13
The equations are gotten from substitution the values to the formula for slope and substituting. Rearranging the equation gives the equation in slope intercept form and in standard form.
