expand (x-4)^5 using the binomial theorem and pascal’s triangle show all necesssry steps
The binomial expansion of the [tex](x-4)^5[/tex] is [tex]x^5+20x^4+160x^3+640x^2+1280x+1024[/tex]
According to the statement
we have given that a equation and we have to expand it by use of the binomial theorem.
So, For this purpose we know that the
A binomial theorem, statement that for any positive integer n, the nth power of the sum of two numbers a and b may be expressed as the sum of n + 1 terms of the form.
And the general formula is
[tex](x+y)^n= ^nC_0x^ny^0+^nC_1x^(n-1)y^1+^nC_2x^(n-2)y^2+...+^nC_nx^0y^n[/tex]
And we have to solve it with the given equation (x-4)^5.
Then
[tex](x-4)^5=x^5+20x^4+(20)/(2)x^3(4^2)+(60)/(6)x^2(4)^3+(120)/(24)x^1(4)^4+(120)/(120)x^0(4)^5[/tex]
Now after solving the equation become
[tex](x-4)^5=x^5+20x^4+160x^3+640x^2+1280x+1024[/tex]
So, The after expanding the given statement with the binomial theorem the result output is
[tex](x-4)^5=x^5+20x^4+160x^3+640x^2+1280x+1024[/tex]
So, The binomial expansion of the [tex](x-4)^5[/tex] is [tex]x^5+20x^4+160x^3+640x^2+1280x+1024[/tex]

Answer:
see explanation
Step-by-step explanation:
to evaluate f(a) substitute x = a into f(x)
f(a) = 5a + 4
---------------------
2f(a) = 2(5a + 4) = 10a + 8
-----------------------
to evaluate f(2a) substitute x = 2a into f(x)
5(a + 2) + 4 = 5a + 10 + 4 = 5a + 14
--------------------------
f(a) + f(2) ← substitute x = 2 into f(x)
= 5a + 4 + 5(2) + 4 = 5a + 4 + 10 + 4 = 5a + 18

Compounding , it will be about
enter your response here years before Tanisha has $1,400.
With annual compounding, the number of years for 1000 to become 1400 is 6.7 years
With continous compounding, the number of years for 1000 to become 1400 is 1.35 years
How long would it take $1000 to become $1,400?With annual compounding, the formula that would be used is:
(In FV / PV) / r
Where:
FV = future value PV = present value r = interest rate(In 1400 / 1000) / 0.05 = 6.7 years
With continous compounding, the formula that would be used is:
(In 1400 / 1000) / (In e^r)
Where r = interest rate

The area of a square quilt is 35 ft 2. How will it look stretched across a queen sized bed measuring 60 inches wide and 80 inches long?
The quilt will be 10.99 inches wider and 9.01 inches shorter than the bed.
What is the relationship between the quilt and the bed?The first step is to determine the dimensions of the quilt.
Dimensions = √35 = 5.92 feet
Now convert the dimensions of the quilt to inches
1 feet = 12 inches
5.92 x 12 = 70.99 inches
Difference in the width of the bed and the quilt = 70.99 - 60 = 10.99
Difference in the length of the bed and the quilt = 80 - 70.99 = 9.01
Here are the options:
A. The quilt will cover half of the surface of the bed.
O B. The quilt will match up with the length of the bed, but 20 inches will hang over the length. °
C. The quit will be 14.6 inches wider and 15.4 inches shorter than the bed. O D. The quilt will be 10.99 inches wider and 9.01 inches shorter than the bed.

Answer:
Step-by-step explanation:
This is classic right triangle trig, cos specifically. Our reference angle is the one marked 26°, the hypotenuse is given as 12, and the side adjacent to the reference angle is our unknown. This is the cosine ratio. Setting up to solve for x:
[tex]cos26=\frac{x}{12}[/tex] and
12cos(26) = x Plug this into your calculator in degree mode to get that
x = 10.8
how tell me how you got answer 5.9 and also if you do at calculate can show me how to do pls thanks.
The steps you have are correct. I'll fill in the gap between step 2 and step 3.
[tex]0.4245 = \frac{2.5}{\text{x}}\\\\0.4245\text{x} = 2.5\\\\\text{x} = \frac{2.5}{0.4245}\\\\\text{x} = 5.8892815\\\\\text{x} = 5.9\\\\[/tex]
I multiplied both sides by x, then divided both sides by 0.4245 to isolate the variable.
With the exception of 2.5, every other decimal value mentioned is approximate.
Which set of ordered pairs could be generated by an exponential function?
The set of ordered pairs that could be generated by an exponential function is; C: (-1,1/2), (0, 1), (1, 2), (2, 4)
How to find the ordered pairs?An exponential function is represented by the general form;
y = abˣ
The above equation means that the value (0, 0) cannot be an ordered pair in an exponential function.
The highlight above means that, the options A, B and D cannot generate an exponential equation because they contain the point (0,0).
Thus, the set of ordered pairs that could be generated by an exponential function is option C: (-1,1/2), (0, 1), (1, 2), (2, 4)
The missing options are;
A. (-1,-1/2), (0, 0),(1,1/2), (2, 1)
