48. B and 47 is out of c and b
Step-by-step explanation:
Angles APD, DPC and CPB are supplementary. (Angles on a straight line)
Therefore Angle APD + Angle DPC + Angle CPB = 180°.
Since Angle DPC = 90° (Right angle),
Angle APD + Angle CPB = 180° - 90° = 90°.
=> (7x + 1) + (9x - 7) = 90
=> 16x - 6 = 90
=> x = 6
Hence arc measure of minor arc AD
= (7x + 1)° = [7(6) + 1]° = 43°.
your correct answer is b 39+n
Answer:
A.385.33
Step-by-step explanation:
24×10= 240
240÷2=120
13^2×pi= 530
530/2=265
265+120=385
Answer:
A
Step-by-step explanation:
So we have the two functions:

And we want to find (f/g)(x).
This is the same as:

So, substitute (2x+5) for f(x) and (x-8) for g(x). So:

Now, we want to find the domain.
Note that this is a rational function. The domain of a rational function is always all real numbers <em>except</em> when the denominator equals 0. This is because, remember, you can't divide by 0!
So, to find the domain restrictions, set the denominator equal to 0 and solve for x. So:

Solve for x. Add 8 to both sides:

So, our domain is all real numbers except for 8. We can check this, when x is 8, our function is 21/0, which is undefined.
Therefore, our answer is A.
And we're done!
