So pythagrorean theorem is the ideal way and easiest way to solve this

a^2+b^2=c^2

8.5^2+11^2=x^2
72.25+121=193.25
square root of 193.25=13.9014 or 13.9 in


9.5^2+15^2=x^2
90.25+225=315.25
square root of 315.25=17.7553 or 17.8 ft

Find the inverse of the function y = 2x2 + 2
Anvisha [2.4K]
We have that
y = 2x²<span> + 2

step 1

</span><span>exchange the value of x for y and the value of y for x
</span>y = 2x² + 2------> x=2y²+2

step 2
clear y variable
 x=2y²+2----> 2y²=x-2----> y²=[(x-2)/2]-----> y=(+/-)√[(x-2)/2]

step 3
the inverse is
f(x)-1=(+/-)√[(x-2)/2]

Can anyone explain me?​
Alika [10]

Answer:

Step-by-step explanation:

a) (a + b)² = (a + b) * (a +b)

  (a + b)³  = (a + b) * (a +b) * (a +b)

 a²- b² = (a +b) (a - b)

Here (a + b) is common in all the three expressions

HCF = (a + b)

b) (x - 1) = (x - 1)

  x² - 1  = (x - 1) * (x + 1)

  (x³ - 1) = (x - 1) (x² + x + 1)

HCF = (x -1)
