Let d = 0.825252525..., then
10d = 8.25252525...=8\frac{25}{10^2-1}=8\frac{25}{99}

Therefore,
d=\frac{8}{10}+\frac{25}{990}=\frac{8(99)+25}{990}=\frac{817}{990}

How many zero pairs must be added to the function
MakcuM [25]

1 zero pair of 25 was added to bring given function into vertex form.

<h3>What is a Zero Pair ?</h3>

A zero Pair is the set of two numbers which when added together gives 0.

The function given is

f(x) = x² -10x -4

To convert it into the vertex form

y = a(x-h)²  +k

f(x) = x² -10x +25 -25 -4

f(x) = x² -10x +5² -25-4

f(x) = (x-5)² -29

Therefore this is the given function's vertex form and

1 zero pair of 25 was added to bring it into that.

Therefore Option D is the answer.

Solve the elimination method
vlada-n [284]

Answer:

C)No Solution

Step-by-step explanation:

Given  2 equations

  • 4x-2y=1
  • 2x-y=2

Mentioned to solve using eliminations method

4x-2y=1

2x-y=2

Multiply second equation with 2

⇒second equation is 4x-2y=4

Now subtract second equation from 1st equation

4x-2y-(4x-2y)=1-4

4x-4x-2y+2y=-3

0+0=3

0=3

But 0≠3

Therefore there exists no solutions for the given pair of equations

Both equations are Parallel lines as they have the same slope

T²= 4π² (M+m) ÷ ug
inessss [21]

Starting with ...

T^2=\dfrac{4\pi^2(M+m)}{ug}

1) Multiply by the inverse of the coefficient multiplying the sum with M, then subtract m.

\dfrac{T^2ug}{4\pi^2}=M+m\\\\M=\dfrac{T^2ug}{4\pi^2}-m

2) Multiply by g/T²

g=\dfrac{4\pi^2(M+m)}{T^2u}
