Answer:
The first one is 1/2
The second one is 1
The third one is 0
Step-by-step explanation:
18. If f(x)=[xsin πx] {where [x] denotes greatest integer function}, then f(x) is:
since x denotes the greatest integers which could the negative or the positive values, also x has a domain of all real numbers, and has no discontinuous point, then x is continuous in (-1,0).
Answer: B]
20. Given that g(x)=1/(x^2+x-1) and f(x)=1/(x-3), then to evaluate the discontinuous point in g(f(x)) we consider the denominator of g(x) and f(x). g(x) has no discontinuous point while f(x) is continuous at all points but x=3. Hence we shall say that g(f(x)) will also be discontinuous at x=3. Hence the answer is:
C] 3
21. Given that f(x)=[tan² x] where [.] is greatest integer function, from this we can see that tan x is continuous at all points apart from the point 180x+90, where x=0,1,2,3....
This implies that since some points are not continuous, then the limit does not exist.
Answer is:
A]
∗ l = 50.6 ft
∗ w = ?
∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.
∗ 6w - 5.8 = 50.6
∗ 6w = 56.4
∗ w = 9.4
Now lets check.
∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6
∗ 6 • 9.4 - 5.8 = l
∗ 56.4 - 5.8 = l
∗ 50.6 = l
⋆The width is 9.4 feet⋆
