Make x the subject of the formula for Q20.
saul85 [17]

Answer:

x = \sqrt{m(\frac{a}{b})^{2} +n  }

Step-by-step explanation:

a\sqrt{(\frac{x^{2} - n }{m}) } = \frac{a^{2} }{b}

\sqrt{\frac{x^{2} - n }{m} } = \frac{a}{b}   [Divide both sides by a]

\frac{x^{2} - n}{m} = (\frac{a}{b} )^{2}   [Square both sides]

x^{2} -n = m(\frac{a}{b} )^{2}   [Multiply both sides by m]

x^{2} =m(\frac{a}{b} )^{2}  + n   [Bring n to the right]

x = \sqrt{m(\frac{a}{b})^{2} +n  }   [Square root both sides]

Today only , a table is being sold at 34% discount. The sale price is $495. What was the price yesterday?
tekilochka [14]
In the given problem, it is given that the table is sold at a discount of only one day and that is today. so the table would be have been sold at its original price yesterday. The discount given today is 34% and the sale price for today is $495.
Let us assume the price of the table yesterday = x
Then we can write the equation as
x = 295 * (100/34)
  = 29500/34
  = 867.64
So the selling price of the table yesterday was $867.64.

The function f(x)=5(2)^x was replaced with f(x)+k , resulting in the function graphed below.
ella [17]
In this problem, you have to find the y- intercept of f(x)=5(2)^x. I graphed mine into a graphing calculator. An algebraic way to find it is to input x=0 in the function. The y-intercept is 5.  You can see the y-intercept for the new one is -2. That means we shifted the graph down 7 units. (Vertical Shift down 7)  
k=-7
