Answer:

∠ 1 = ∠ 2 = 75°

Step-by-step explanation:

The sum of the 3 angles in Δ CDE = 180°

sum the angles and equate to 180°

∠ 1 + 38° + 67° = 180°

∠ 1 + 105° = 180° ( subtract 105° from both sides )

∠ 1 = 75°

∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so

∠ 2 = 75°

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]

One day Mr. Pritz drove for 6 1/3 hours. The next day he drove 9 1/2 hours. For how many hours did he drive during the two days?

Answer:

Step-by-step explanation:

First convert them into improper fractions: $6\frac{1}{3} =\frac{19}{3}$ and $9\frac{1}{2} =\frac{19}{2}$ . Now we add: $\frac{19}{2}+\frac{19}{3}=\frac{95}{6}$ or $15\frac{5}{6}$ .

-4x+2=-6;2 us this a solution to the equation

Alex17521 [72]

Hi there! Yes, x = 2 is a solution to this equation.

Let's solve this equation step by step!
$- 4x + 2 = - 6$

Subtract 2 from both sides.
$- 4x + 2 - 2 = - 6 - 2 \\ - 4x = - 8$

Now divide both sides of the equation by -4 (and remember that when dividing two negatives we end up with a positive).
$x = \frac{ - 8}{ - 4} = 2$

And therefore x = 2 is a solution to this equation.
~ Hope this helps you!
