9514 1404 393
Explanation:
We can start with the relations ...
[tex]\displaystyle\left(x+\frac{1}{x}\right)^3=\left(x^3+\frac{1}{x^3}\right)+3\left(x+\frac{1}{x}\right)\\\\\left(x+\frac{1}{x}\right)^5=\left(x^5+\frac{1}{x^5}\right)+5\left(x^3+\frac{1}{x^3}\right)+10\left(x+\frac{1}{x}\right)\\\\\textsf{From these, we can derive ...}\\\\x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(\left(x+\frac{1}{x}\right)^3-3\left(x+\frac{1}{x}\right)\right)-10\left(x+\frac{1}{x}\right)[/tex]
[tex]\displaystyle x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(x+\frac{1}{x}\right)^3+5\left(x+\frac{1}{x}\right)\right)\\\\x^5+\frac{1}{x^5}=3^5 -5(3^3)+5(3)\\\\=((3^2-5)3^2+5)\cdot3=(4\cdot9+5)\cdot3=(41)(3)\\\\=\boxed{123}[/tex]

The hypotenuse of the right triangle is 5y inches long. The lengths of the legs are x + 8 and x + 3 inches. If the perimeter of the triangle is 76
inches and the length of the hypotenuse minus the length of the shorter leg is 17 inches, how many inches long is the hypotenuse?
X + 8
5y
x + 3
Answer: 35 inches.
Step-by-step explanation:
We know that:
hypotenuse = 5*y in
cathetus 1 = (x + 8) in
cathetus 2 = (x + 3) in
The perimeter of the triangle is 76 inches, then:
5*y + (x + 8) + (x + 3) = 76
5*y + 2*x + 13 = 76
We also know that the length of the hypotenuse minus the length of the shorter leg is 17 in.
The shorter leg is x + 3, then:
5*y - (x + 3) = 17
Then we have the equations:
5*y + 2*x + 11 = 76
5*y - (x + 3) = 17
With only these two we can solve the system, first we need to isolate one of the variables in one of the equations, i will isolate x in the second equation.
x = 5*y - 3 - 17 = 5*y - 20
x = 5*y - 20
Now we can replace this in the other equation, we get:
5*y + 2*x + 11 = 76
5*y + 2*(5*y - 20) + 11 = 76
15*y - 40 + 13 = 76
15*y - 29 = 76
15*y = 76 + 29 = 105
and remember that the hypotenuse is equal to 5*y, then we want to get:
3*(5*y) = 105
5*y = 105/3 = 35
5*y = 35
Then te length of the hypotenuse is 35 inches.
5^3x - 5^3x-1
[tex] {5}^{3x} - {5}^{3x - 1} = 4[/tex]
Answer:
x=1/3
Step-by-step explanation:
Factor out 5^3x
5^3x(1-1/5)=4
Combine the fractions
5^3x(4/5)=4
Multiply both sides by 5/4
5^3x=5
Now we have the same base of 5 so we can set the exponents equal to one another (the exponent of 5 is 1)
3x=1
X=1/3
solve for 65+5x and show work !!!
Answer:
x = -13
Step-by-step explanation:
65 + 5x = 0
65 = -5x
divide by -5
-13 = x
Answer:
x = 13
Step-by-step explanation:
You have to get x by itself
so you divide 5 by 65
Then X is by itself and your answer is 5/65

What is the present value of an ordinary annuity having semi-annual payments of 8000 for 12 years with an interest rate of 12%compound semi- annually?
Answer:
PV= $100,402.86
Step-by-step explanation:
To calculate the present value, first, we need to determine the future value using the following formula:
FV= {A*[(1+i)^n-1]}/i
A= semiannual deposit
n=12*2= 24 semesters
i= 0.12/2= 0.06
FV= {8,000*[(1.06^24) - 1]} / 0.06
FV= $406,524.62
Now, the present value:
PV= FV / (1+i)^n
PV= 406,524.62 / 1.06^24
PV= $100,402.86
what is the value of y???

B angle and C angle are equal so...
B = 75
75 = (3x)
75 / 3 = 25
x = 25
a triangles angles equals 180 degrees
75 + 75 = 150
180 = 150 + ?
180 - 150 = 30
A = 30 degrees
4y + 10 = 30
get the y on it's own side
4y + 10 - 10 = 4y
30 - 10 = 20
4y = 20
4y / 4 = y
20 / 4 = 5
y = 5

Answer:
1/2 ÷ 4 = 8
Step-by-step explanation:
Dividing fractions is as easy as pie. Flip the second and multiply.
1/2 ÷ 4 = 1/8
A whole number secretly has a 1 underneath, like this: 4/1
Flip the second number over to get 1/4, then multiply straight across.
[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex]
Try to do the same for the other answers and see if they're right (they're not).

Answer:
I believe it is because it is being transferred to kinetic energy
Step-by-step explanation:
As the puck falls, it loses potential energy and gains kinetic energy because it is now falling, which causes movement due to gravity. And as we know, kinetic energy is energy which a body possesses by virtue of being in motion
Please help with geometry work asap!!!
Answer:
z = 100°
x = 40°
Step-by-step explanation:
Triangle CBD is isosceles so there are two 50°
DBC = 50°
That means BDC = 80° because 180(sum of angles in triangle) - 50 - 50 = 80
Z = 100° bc angle of straight line is 180° and 180 - 80 = 100
Now triangle ADB is also isosceles because there are two sides of equal length
So there will be 2*x + 100 = 180
x = 40°
