2√5(√3+3√5)
(1.73+3+2.23)= (6.96)
2√5= 4.23
4.23(6.96)= 29.44
We write f(x) in terms of y I.e y=7x-1/2.
Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.
Make x the subject, x=2y+1/14,
Thus the inverse f(x)=2x+1/14
Answer:
The answer is Phone Surveys.
Step-by-step explanation:
We can say that there are 4 main types of survey methods and they are "In-Person Surveys", "E-mail Surveys", "Phone Surveys" and "Online Surveys".
In-Person Surveys are out of the question in the situation that is described because we need the fastest possible method.
E-mail Surveys and Online Surveys are at completed at a time that the other party chooses so we have no control over how fast we can get the results.
The fastest and best option we can use for the situation Dr. Lee's in is Phone Surveys because they are direct and give quick results over a short amount of time and they can be scheduled according to our needs.
I hope this answer helps.
Answer:
x = 12 and x = -4
Step-by-step explanation:
abs (x-4) = 8
When we have absolute value equations, we get two solutions, one positive and one negative
x-4 = 8 and x-4 = -8
Add 4 to both sides
x-4+4 = 8+4 x-4+4=-8+4
x = 12 and x = -4
