Square root shows up
step 1
[ 10 + sqrt(3) ] * 1/2 = 5 + 1/2sqrt(3)
sqrt(90) = sqrt( 3 * 3 * 10) = 3 sqrt(10)
hope this helps : P
step 2
multiply both above together:
3sqrt(10) * [ 5 + 1/2sqrt(3) ] = 15 sqrt(10) + 3/2sqrt(30)
Answer for Question 1 is option 2
Answer for Question 2 is option 3
Answer for Question 3 is option 3
Step-by-step explanation:
For question 1 by plotting the two points we get the coordinates as (-2, 3) and (2, 1) where the x values are -2, 2 and the y values are 3, 1 respectively. By substituting values of x in the formula given we get that equation 2 satisfies the values of y as in the graph.
For question 2 the plotted line is split into two parts where one half is for values of x <2 and the other half is for values of x>2. By finding out the coordinates we get them as (2,-2), (1,-2.5) and (0,-3) for x<2 and by substituting the values of x in the formula we get option 3 as our answer.
For question 3 we need to find the value of y when x=3 and the first condition is only for values greater than 3 so we take the second condition and substitute the value of x=3 and we get the value of y as 5 so the answer is option 3
