A^2+b^2=c^2
a^2= 324
b^2= 6,400
324+6,400=c^2
6,724=c^2
c=82

If 6^ = 1/126 find the value of x <br><br> Please ask help with b
Artemon [7]

Answer:

  a) x = -3

  b) 1/250

Step-by-step explanation:

The applicable rule of exponents is ...

  a^-b = 1/a^b

__

a) It is helpful to know that 216 = 6^3.* Then you would realize that ...

  6^x=\dfrac{1}{216}=\dfrac{1}{6^3}=6^{-3}\\\\x=-3

If you don't know that, then you can solve the equation using logarithms. Taking the log of both sides, you have ...

  x·log(6) = log(1/216)

  x = log(1/216)/log(6) = -3

__

b)

  5^{-3}\times 2^{-1}=\dfrac{1}{5^3}\times\dfrac{1}{2^1}=\dfrac{1}{125}\times\dfrac{1}{2}=\boxed{\dfrac{1}{250}}

_____

* This would be on your list of cubes of small integers that you might want to memorize, along with squares of numbers less than 20.

Prove that (sec theta-cos theta) ( cot theta+tan theta) = tan theta ×sec theta​
meriva

Given:

(\sec \theta \cos \theta)(\cot \theta+\tan \theta)=\tan \theta \sec \theta

To prove:

The given statement.

Proof:

We have,

(\sec \theta -\cos \theta)(\cot \theta+\tan \theta)=\tan \theta \sec \theta

Taking LHS, we get

LHS=(\sec \theta -\cos \theta)(\cot \theta+\tan \theta)

LHS=(\dfrac{1}{\cos \theta }-\cos \theta)(\dfrac{\cos \theta}{\sin \theta}+\dfrac{\sin \theta}{\cos \theta})

LHS=(\dfrac{1-\cos^2 \theta }{\cos \theta })(\dfrac{\cos^2 \theta+\sin^2 \theta}{\sin \theta\cos \theta})

LHS=(\dfrac{\sin^2 \theta }{\cos \theta })(\dfrac{1}{\sin \theta\cos \theta})          [\because \cos^2 \theta+\sin^2 \theta=1]

LHS=(\dfrac{\sin \theta }{\cos \theta })(\dfrac{1}{\cos \theta})

LHS=\tan \theta \sec \theta

LHS=RHS

Hence proved.

How many times does the graph of the function below interect or touch the x-axis? y=-2x^2+3x+5
Andrei [34K]

Answer:

Two times at (-1,0) and (2.5,0)

Step-by-step explanation:

When the graph intersects or touches x-axis, y is equal to 0

so y = -2x^2 + 3x + 5

=> 0 = -2x^2 + 3x + 5

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = -2

    b = 3

    c = 5

substitute in the formula

x = [-3 +/- √(3^2 - 4x-2x5)]/2(-2)

x = [-3 +/- √(9 + 40)]/(-4)

x = [-3 +/- 7]/(-4)

x1 = (-3 + 7)/(-4) = 4/-4 = -1

x2 = (-3 - 7)/(-4) = -10/-4 = 5/2 = 2.5

so the graph has two x-intercepts (-1,0) and (2.5,0), therefore it intersects x-axis two times
